AZ-600 Foundations - Planning a Hybrid Cloud with Azure Stack Hub

The AZ-600 certification, officially titled "Configuring and Operating a Hybrid Cloud with Microsoft Azure Stack Hub," is an associate-level credential that validates a professional's expertise in this specialized hybrid cloud platform. It certifies that an individual has the subject matter knowledge required to deliver Infrastructure as a Service (IaaS) and Platform as a Service (PaaS) offerings from within their own datacenter using the power of Azure Stack Hub. This exam is designed for administrators and operators who are responsible for the day-to-day management, monitoring, and maintenance of the Azure Stack Hub infrastructure, ensuring its health and functionality.

Passing the AZ-600 exam demonstrates a comprehensive skill set. A certified professional is capable of planning a deployment, managing infrastructure certificates, handling registration and billing, and providing services to tenants. This includes managing the marketplace, offering resource providers like App Service, and configuring plans and offers. The exam's focus is practical, centering on the operational tasks that are crucial for running a successful and efficient hybrid cloud environment. It is a testament to an individual's ability to bridge the gap between on-premises infrastructure and the Azure cloud, a critical need in modern IT.

Candidates pursuing the AZ-600 should possess a strong background in managing on-premises systems and a solid understanding of Azure concepts. The certification is not just about knowing the features of Azure Stack Hub but also about applying that knowledge to real-world scenarios involving deployment, service delivery, and infrastructure lifecycle management. It signifies a deep understanding of how to operate a cloud platform that extends Azure services to any location, providing a consistent experience for developers and users alike, which is a key goal of any hybrid strategy.

The Role of the Azure Stack Hub Operator

The target audience for the AZ-600 certification is primarily Azure administrators or infrastructure administrators who are transitioning to managing an Azure Stack Hub environment. These individuals are responsible for the end-to-end lifecycle of the platform. Their duties range from the initial planning and deployment phases to ongoing operational tasks such as updating the system, managing capacity, and troubleshooting issues. This role is pivotal in ensuring that the hybrid cloud meets the organization's technical and business requirements, providing a stable platform for tenant workloads.

A key responsibility for an Azure Stack Hub operator, and a core focus of the AZ-600 exam, is service provisioning. This involves more than just keeping the lights on; it requires the operator to act as a cloud service provider to their internal or external customers. They must manage the Azure Stack Hub Marketplace, curating a catalog of services and applications. They create and manage plans, offers, and quotas to control resource consumption and deliver services in a structured, multi-tenant fashion. This requires a blend of technical acumen and a service-oriented mindset.

Furthermore, the operator is the first line of defense for maintaining the health and security of the system. They are tasked with monitoring the infrastructure, responding to alerts, and performing necessary maintenance. This includes critical procedures like rotating secrets and certificates, managing system updates, and planning for business continuity and disaster recovery. The AZ-600 certification validates that an individual has the skills to perform these diverse and critical functions, making them an essential asset for any organization leveraging Azure Stack Hub.

Planning Your AZ-600 Deployment Model

A foundational element of the AZ-600 curriculum is the ability to plan an Azure Stack Hub deployment effectively. The first major decision is selecting the appropriate deployment model for a given scenario. Azure Stack Hub can be deployed in either a connected or a disconnected mode. A connected deployment maintains a connection to Azure, which allows for integrated identity management with Azure Active Directory (Azure AD), a unified marketplace, and integrated billing. This is the most common and feature-rich deployment model, offering a seamless hybrid experience.

In contrast, a disconnected deployment is designed for environments with no or limited internet connectivity, such as secure facilities, mobile field units, or marine vessels. In this model, the Azure Stack Hub is completely isolated. Identity management must be handled by Active Directory Federation Services (AD FS), and the marketplace must be populated manually. Billing and usage data are also managed differently, requiring an export and import process. An AZ-600 candidate must be able to analyze business and technical requirements to recommend the correct model, understanding the trade-offs and operational differences of each.

The choice of deployment model has cascading effects on all other aspects of planning and operations. It dictates the identity provider, the method for managing the marketplace, the approach to updates, and the strategy for usage reporting. The AZ-600 exam will present scenarios requiring the candidate to weigh factors like connectivity, security posture, and operational overhead to make an informed recommendation. This decision is critical and forms the basis for the entire hybrid cloud architecture, making it a crucial topic for any aspiring Azure Stack Hub operator.

Developing a Name Resolution Strategy

Proper name resolution is critical for the functionality of an Azure Stack Hub deployment, and planning a strategy is a key skill tested in the AZ-600 exam. The operator must decide how the various infrastructure roles and endpoints within the Azure Stack Hub will resolve both internal and external names. A robust DNS infrastructure is a prerequisite. The strategy typically involves integrating with an organization's existing DNS servers. The Azure Stack Hub internal DNS service must be configured to forward requests for external domains to these existing servers.

The planning process involves defining conditional forwarders. For example, requests for the corporate domain name must be forwarded to the corporate DNS servers, while requests for public internet domains are forwarded to public DNS servers. An AZ-600 candidate needs to understand these concepts and be able to design a DNS forwarding architecture that ensures reliable name resolution for all components, including the privileged endpoint, the administrator portal, and tenant virtual machines. Misconfiguration of DNS is a common source of deployment and operational failures.

Furthermore, the strategy must account for the fully qualified domain name (FQDN) and region name chosen for the deployment. All the public-facing endpoints of the Azure Stack Hub will use this FQDN. The DNS strategy must include creating the necessary DNS zone and records to support these endpoints before the deployment begins. The AZ-600 exam requires a practical understanding of these requirements, including the specific DNS records needed to support services and user access, ensuring a seamless and functional deployment from day one.

Designing an IP Address Strategy

A well-designed IP address strategy is fundamental to a successful Azure Stack Hub deployment and a core topic for the AZ-600 certification. The operator must plan for several distinct IP address ranges to support the underlying physical network and the software-defined network (SDN) components. This includes a range for public VIPs (Virtual IP addresses), which are assigned to tenant services to make them accessible from outside the Azure Stack Hub. The size of this public IP pool must be carefully calculated based on the expected number of tenant services.

In addition to the public VIP pool, the strategy must define IP ranges for the internal infrastructure network. This network facilitates communication between the various Azure Stack Hub infrastructure components, such as the infrastructure controllers and storage services. The operator must also plan for the switch management network and the hardware lifecycle host (HLH) network. The AZ-600 exam expects a candidate to understand the purpose of each of these networks and be able to recommend appropriate CIDR ranges that do not overlap with existing datacenter networks.

The plan must also consider routing. The operator needs to decide whether to use static routes or a dynamic routing protocol like Border Gateway Protocol (BGP) to advertise the public VIP network to the broader corporate network. BGP is generally the recommended approach as it provides automatic failover and simplifies network management. An AZ-600 professional must understand the prerequisites for BGP, including the need for autonomous system numbers (ASNs) and peer IP addresses, and be able to design an IP and routing strategy that ensures robust and resilient connectivity.

Datacenter Firewall Integration

Integrating Azure Stack Hub with the datacenter network requires careful planning of firewall rules, a critical security and connectivity topic covered by the AZ-600 exam. Azure Stack Hub is not a security appliance; it relies on an upstream firewall or border device to protect it from malicious traffic. The operator must work with the network security team to create a comprehensive firewall integration strategy that allows legitimate traffic while blocking potential threats. This involves defining rules for a long list of required ports and protocols.

The strategy must address both inbound and outbound traffic. Inbound rules are needed to allow access to the administrator and user portals, as well as to tenant applications that are exposed via public IP addresses. Outbound rules are necessary for the Azure Stack Hub to communicate with external resources. In a connected deployment, this includes communication with Azure for registration, billing, and marketplace syndication. It also includes access to NTP for time synchronization and DNS for name resolution.

An AZ-600 candidate must be familiar with the extensive list of required URLs, ports, and protocols that must be opened on the datacenter firewall. The official documentation provides this information, and a certified professional is expected to know how to interpret and apply it. They should be able to recommend a strategy that adheres to the principle of least privilege, opening only what is absolutely necessary for the system to function correctly and securely. This detailed planning prevents connectivity issues during and after deployment.

Choosing an Identity Provider

The choice of an identity provider is one of the most important decisions in planning an Azure Stack Hub deployment and a key area of study for the AZ-600 exam. This choice is directly tied to the deployment model. For a connected deployment, the recommended and most integrated option is Azure Active Directory (Azure AD). Using Azure AD allows for a single identity for users across both Azure and Azure Stack Hub, enabling seamless management of permissions and access through a unified identity plane. This simplifies the user experience and administrative overhead.

For a disconnected deployment where there is no connectivity to Azure, Active Directory Federation Services (AD FS) is the required identity provider. In this model, a dedicated AD FS instance, backed by an on-premises Active Directory, is used to handle all authentication and authorization for the Azure Stack Hub. Setting up AD FS for this purpose requires careful planning, including the deployment of the necessary servers and the generation of specific certificates. An AZ-600 candidate must understand the infrastructure requirements and configuration steps for an AD FS-backed deployment.

The exam will test a professional's ability to choose the correct provider based on a scenario's requirements. This involves understanding the implications for user management, application authentication, and service principal creation. A candidate should also be proficient with the Azure Stack Hub Readiness Checker tool. This tool is used before deployment to validate that the chosen identity provider, whether Azure AD or AD FS, is configured correctly and meets all the prerequisites, helping to ensure a smooth and successful deployment process.

Planning Infrastructure Certificates for AZ-600

A critical and often complex prerequisite for deploying Azure Stack Hub is the management of infrastructure certificates. This is a significant portion of the AZ-600 curriculum. These Public Key Infrastructure (PKI) certificates are used to secure all the key endpoints of the Azure Stack Hub, including the administrator and user portals, and internal infrastructure communication. A candidate must be able to plan for these certificates, understanding the specific names and subject alternative names (SANs) required for each one.

The first decision in the certificate planning process is whether to use certificates from an internal enterprise Certificate Authority (CA) or from a public CA. For production environments, a public CA is often recommended because the certificates will be automatically trusted by client devices. Using an internal enterprise CA is also a valid option, but it requires that the CA's root certificate be distributed and trusted by all devices that will connect to the Azure Stack Hub. The AZ-600 exam requires a professional to understand the pros and cons of each approach.

Once the CA type is chosen, the operator must generate the certificate signing requests (CSRs) for a list of specific endpoints. This list includes endpoints for the public portal, the admin portal, authentication, and various resource providers. The operator needs to prepare these certificates with the correct attributes and then export them as PFX files, each secured with a password. This meticulous preparation is vital for a successful deployment, and the AZ-600 certification validates a professional's ability to execute this process without error.

Validating and Managing Certificates

After preparing the necessary PKI certificates, it is crucial to validate them before starting the Azure Stack Hub deployment. The AZ-600 curriculum emphasizes the use of the Azure Stack Hub Readiness Checker tool for this purpose. This PowerShell-based tool performs a series of tests on the prepared certificates to ensure they meet all the stringent requirements. It checks for correct subject names, subject alternative names, key usage attributes, and the validity period. Running this tool and resolving any reported issues is a mandatory pre-deployment step.

Certificate management does not end after the initial deployment. These certificates have a limited lifespan and will eventually expire. A key operational task for an Azure Stack Hub operator, and a topic covered in the AZ-600 exam, is the process of rotating these infrastructure certificates before they expire. This rotation process is a sensitive operation that must be performed carefully to avoid any service disruption. It involves generating new certificates and then using a dedicated process through the privileged endpoint to apply them to the system.

The operator must continuously monitor the validity of the infrastructure certificates. The administrator portal provides a view of the certificate status and will raise alerts as they approach their expiration date. An AZ-600 certified professional is expected to be proactive in managing the certificate lifecycle, understanding the tools and procedures for rotation, and being able to troubleshoot any issues that may arise during the process. This ensures the continued security and availability of the Azure Stack Hub environment.

Managing AZ-600 Registration and Billing

Every Azure Stack Hub deployment must be registered with Azure. This registration process links the on-premises instance to an Azure subscription, which is a fundamental concept for the AZ-600 exam. The operator must first recommend a registration model. The two primary models are pay-as-you-use and capacity-based. The pay-as-you-use model meters the consumption of services on the Azure Stack Hub, and the billing is processed through the linked Azure subscription. This offers a flexible, cloud-like consumption model.

The capacity model involves an upfront license based on the number of physical cores in the Azure Stack Hub. This provides a fixed, predictable cost for the software services. An AZ-600 professional needs to understand the financial and operational implications of each model to recommend the best fit for their organization's needs. The registration process itself differs for connected and disconnected environments. In a connected environment, the registration is done directly through the administrator portal with credentials for the Azure subscription.

For a disconnected environment, the process is manual. The operator must create an offline registration package, transfer it to a connected machine, upload it to the Azure portal, and then download the registration confirmation to be imported back into the Azure Stack Hub. An AZ-600 certified operator must be proficient in both methods. After registration, they are also responsible for managing usage data reporting. This involves monitoring the connection to Azure for usage reporting and knowing how to use the Usage API to retrieve and reconcile billing data.

Setting Up the Management Environment

To effectively manage an Azure Stack Hub, an operator needs a properly configured management environment. The AZ-600 exam covers the necessary steps to set up this environment. The primary management interfaces for Azure Stack Hub are the administrator portal, PowerShell, and the Azure CLI. To ensure secure access, operators should use a dedicated, hardened workstation, often referred to as an Operator Access Workstation or a Secure Admin Workstation. This helps to protect the administrative credentials from being compromised.

A key task is installing and configuring the correct PowerShell modules for Azure Stack Hub. This involves installing the Azure Stack Hub-specific modules and connecting to the correct Azure Resource Manager endpoints for both the administrator and tenant environments. An AZ-600 professional must know the PowerShell cmdlets to register the Azure Stack Hub environment and to switch between different environments. They also need to know how to install and configure the Azure CLI for use with Azure Stack Hub, providing an alternative command-line interface for management.

The setup process also includes downloading and using the Azure Stack Hub PowerShell tools from the popular code-hosting platform. These tools contain scripts for various administrative and operational tasks, including certificate validation and management of marketplace items. Understanding how to use these pre-built tools can significantly improve an operator's efficiency. The AZ-600 certification ensures that a professional can establish a secure and functional management workstation, equipped with all the necessary tools and configurations to manage the hybrid cloud platform effectively.

Connecting to Administrative Endpoints

An Azure Stack Hub operator interacts with the system through several key endpoints, and the AZ-600 exam requires a thorough understanding of how to connect to and use them. The primary graphical interface is the administrator portal, which provides a web-based dashboard for monitoring health, managing services, and configuring the system. Securing access to this portal is paramount. In addition to the portal, there are Azure Resource Manager endpoints that are used by PowerShell and the Azure CLI for programmatic management.

A critical component for advanced troubleshooting and maintenance is the privileged endpoint (PEP). The PEP is a pre-configured PowerShell remote session that provides access to the low-level infrastructure of the Azure Stack Hub. It is used for tasks that cannot be performed through the administrator portal, such as collecting advanced diagnostic logs, rotating certificates, and performing system recovery operations. An AZ-600 professional must know how to connect to the PEP from a secure workstation, as access to it is highly privileged.

The AZ-600 curriculum also covers the Emergency VM Access Service (EVA), also known as the Emergency Console. This service provides console-level access to the infrastructure virtual machines in a worst-case scenario where other management interfaces are unavailable. It is a tool of last resort for emergency diagnostics and recovery. A certified operator must understand the purpose of the EVA, how to enable it, and the procedures for using it securely. Mastery of all these administrative endpoints is essential for comprehensive system management.

Managing the AZ-600 Azure Stack Hub Marketplace

A core function of an Azure Stack Hub operator, and a key domain in the AZ-600 exam, is to manage the Marketplace. The Marketplace is the catalog of services, applications, and virtual machine images that are available for tenants to deploy. The operator is responsible for curating this catalog to meet the needs of their users. In a connected deployment, the operator can syndicate items directly from the global Azure Marketplace. This allows them to easily bring in a wide range of popular and trusted items from Microsoft and third-party vendors.

For a disconnected or partially connected environment, populating the Marketplace is a manual process. The operator must use the Marketplace Syndication tool on a connected machine to download the desired items. These items are then transferred to the disconnected environment and imported into the Azure Stack Hub Marketplace. An AZ-600 professional needs to be proficient in both the connected and disconnected syndication processes, understanding the steps and tools involved in each.

Beyond syndicating items, operators can also create their own custom Marketplace items. This is a powerful feature for publishing standardized, pre-approved solutions for the organization. This could be a custom virtual machine image with specific software pre-installed, or a custom Azure Resource Manager (ARM) template that deploys a multi-tier application. The AZ-600 exam requires a candidate to know how to create these custom items, package them correctly, and manage their lifecycle, including updating and retiring them as needed.

Offering the App Service Resource Provider

To provide Platform as a Service (PaaS) web hosting capabilities, an operator must deploy and manage the App Service resource provider. This is a complex add-on service that brings the functionality of Azure App Service to the Azure Stack Hub. Planning and deploying this resource provider is a significant task and a major topic within the AZ-600 curriculum. The planning phase involves considerations for capacity, networking, and the required supporting infrastructure, such as a file server and a SQL Server instance.

The deployment of the App Service resource provider is a multi-step process that is initiated from the administrator portal. It involves deploying several infrastructure roles, including controllers, management servers, publishers, front ends, and workers. An AZ-600 candidate must understand the function of each of these roles. For example, worker tiers host the actual tenant applications, and they can be scaled out to provide more capacity. The operator must be able to deploy the resource provider and then scale the different roles based on demand.

Ongoing management is also critical. An AZ-600 certified professional is responsible for the lifecycle of the App Service resource provider. This includes applying updates, rotating the secrets and certificates used by the service, and monitoring its health. They must also have a strategy for backing up the App Service, which includes the SQL databases that store its configuration and the file share that stores the web content. This ensures that the PaaS offering is robust, secure, and resilient.

Offering the Event Hubs Resource Provider

Similar to App Service, the Event Hubs resource provider is another add-on that brings a specific Azure PaaS capability to Azure Stack Hub. Event Hubs is a real-time data ingestion service that can handle millions of events per second, making it suitable for big data and IoT scenarios. The AZ-600 exam covers the operator's responsibilities in planning, deploying, and maintaining this resource provider. The planning process is similar to that of App Service, requiring careful consideration of capacity and the necessary prerequisites.

The deployment is performed through the administrator portal, and it sets up the necessary infrastructure to run the Event Hubs service within the Azure Stack Hub environment. Once deployed, the operator is responsible for the ongoing health and maintenance of the service. This includes applying updates to the resource provider as they are released by Microsoft. These updates provide new features, performance improvements, and security patches, so keeping the provider current is essential.

As with other components, the Event Hubs resource provider is secured by a set of secrets and certificates that must be managed. The AZ-600 curriculum requires a professional to know the process for rotating these secrets and certificates before they expire to prevent any interruption in service. This lifecycle management ensures that the Event Hubs service remains secure and available for tenants who rely on it for their data streaming and telemetry applications, making PaaS a viable offering on the hybrid platform.

Creating and Managing Plans, Quotas, and Offers

The foundation of service delivery in Azure Stack Hub is the structure of plans, quotas, and offers. This multi-tenant framework is a central concept in the AZ-600 exam. An operator begins by creating quotas. Quotas define the limits on the resources that a user can consume. For example, a quota for compute might limit the number of VMs, the number of cores, and the amount of RAM a subscription can use. There are separate quotas for each service, such as storage, network, and compute.

Next, the operator groups one or more quotas together into a plan. A plan represents a set of services with specific limits. For example, an operator might create a "Basic" plan with modest quotas for compute and storage, and a "Premium" plan with much higher limits. There are two types of plans: base plans, which are included in an offer by default, and add-on plans, which a user can choose to add to their subscription later to gain access to more services or higher limits.

Finally, the operator creates an offer. An offer is what is presented to the user for subscription. It contains one or more base plans and can also include optional add-on plans. The operator can make offers public, so any user can subscribe to them, or private, so they are only available to specific tenants. An AZ-600 professional must be an expert in this entire workflow, able to design a flexible and logical service catalog that meets the needs of different user groups while allowing the operator to maintain control over resource consumption.

Managing User Subscriptions

Once offers are created, users can subscribe to them, which creates a user subscription. This subscription is the container for all the resources that a user deploys. Managing these subscriptions is a key day-to-day task for an Azure Stack Hub operator and a topic covered by the AZ-600 exam. The operator can view all user subscriptions in the administrator portal, monitor their resource consumption, and manage their state.

A common administrative task is changing the owner of a subscription. This might be necessary if an employee changes roles or leaves the organization. The AZ-600 curriculum requires a candidate to know the process for transferring ownership, which ensures that someone is always accountable for the resources within the subscription. The operator can also add and remove add-on plans from a user's subscription, allowing for dynamic adjustment of their available services and quotas.

The operator also has the ability to disable or delete a user subscription. Disabling a subscription prevents the user from deploying new resources but keeps their existing resources running. This can be used as a temporary measure, for example, if a billing issue needs to be resolved. Deleting a subscription is a permanent action that removes the subscription and all the resources within it. An AZ-600 certified professional must understand the implications of these actions and use them appropriately to manage the tenant lifecycle.

Managing Identity and Access for AZ-600

Effective identity and access management (IAM) is crucial for securing a multi-tenant cloud platform like Azure Stack Hub. The AZ-600 exam thoroughly covers the operator's role in managing access for both administrators and tenants. A fundamental task is assigning users and groups to roles. Azure Stack Hub uses role-based access control (RBAC), just like Azure. The operator can assign built-in roles, such as Owner, Contributor, and Reader, to users and groups at different scopes, such as the entire system, a specific user subscription, or a resource group.

A key concept for the AZ-600 is understanding the principle of delegated administration. An operator should not manage tenant resources directly. Instead, they should delegate management tasks by assigning roles to the appropriate users within the tenant's subscription. The operator might also need to define custom RBAC roles. For example, they could create a custom role that allows a user to manage virtual machines but not the virtual network. This allows for fine-grained control that aligns with the principle of least privilege.

The operator is also responsible for managing service principals. A service principal is an identity used by applications, services, or automation tools to access resources. An AZ-600 professional must know how to grant an application access to resources by creating a service principal and assigning it an appropriate role. This is essential for enabling DevOps and automation scenarios on the platform, allowing CI/CD pipelines or management scripts to interact with the Azure Stack Hub environment securely.

Managing Multi-Tenancy

Azure Stack Hub is designed as a multi-tenant platform, and a significant part of the AZ-600 curriculum is focused on managing this aspect. In an environment where the identity provider is Azure AD, an operator can configure the Azure Stack Hub to support users from multiple Azure AD tenant directories. This is common in scenarios where a service provider is hosting multiple customer organizations on a single Azure Stack Hub instance. The operator is responsible for registering these tenant directories with the platform.

The registration process establishes a trust relationship, allowing users from the guest Azure AD tenant to authenticate and access the Azure Stack Hub. The AZ-600 exam requires a candidate to know the steps to register a new tenant directory and, just as importantly, how to update or unregister a directory if a customer relationship ends. This lifecycle management is crucial for maintaining a clean and secure multi-tenant environment.

Once a tenant directory is registered, the operator can create offers and delegate subscriptions to users from that directory. This allows for complete isolation between tenants, where each tenant manages their own resources within their subscription without having visibility into other tenants' environments. An AZ-600 certified professional must have a solid grasp of these multi-tenancy concepts to operate an Azure Stack Hub as a true cloud service provider, whether for internal business units or external customers.

Monitoring System Health with the Administrator Portal

Proactive monitoring is a primary responsibility of an Azure Stack Hub operator. The AZ-600 certification validates a professional's ability to maintain system health, and the first tool for this is the administrator portal. The portal provides a centralized dashboard with at-a-glance information about the health and status of the entire system. It shows the status of infrastructure roles, resource providers, and the physical nodes of the scale unit.

The portal also features a robust alerting system. It automatically generates alerts for a wide range of issues, from hardware failures like a broken disk to software problems like an unresponsive infrastructure role. An AZ-600 professional must know how to interpret and respond to these alerts. This involves understanding the alert severity, gathering more information about the cause, and following the recommended remediation steps provided in the alert details. Timely and effective response to alerts is key to preventing minor issues from escalating into major outages.

Beyond alerts, the operator can use the portal to monitor capacity. There are dedicated dashboards for monitoring the usage of storage, memory, CPU, and public IP addresses. This allows the operator to track consumption trends and proactively plan for capacity expansion before resources are exhausted. The ability to use the administrator portal effectively as a monitoring and health assessment tool is a fundamental skill for any operator and a core competency tested by the AZ-600 exam.

Monitoring with PowerShell and the REST API

While the administrator portal is excellent for visual monitoring, PowerShell and the REST API provide powerful tools for automated and programmatic health monitoring. The AZ-600 exam expects a candidate to be proficient in using these interfaces. A key PowerShell cmdlet for health validation is Test-AzureStack. This comprehensive command runs a series of tests against the entire system to check the status of infrastructure services, hardware, and registration. It can be used for routine health checks or for diagnosing a specific problem.

An AZ-600 professional should know how to use PowerShell to connect to the administrator endpoint and query for health and alert information. This allows for the creation of custom monitoring scripts. For example, a script could be scheduled to run periodically, check for any new critical alerts, and send a notification to the operations team. This kind of automation is essential for managing a large or complex environment efficiently and is a key skill for a modern cloud operator.

For even more advanced integration, the operator can use the REST API. The same health and alert information that is available in the portal and through PowerShell can also be accessed via REST API calls. This allows for integration with third-party monitoring and ticketing systems. An AZ-600 certified operator understands the value of this integration and has a conceptual knowledge of how to use the API to pull health data, enabling a holistic and integrated monitoring strategy for the entire datacenter.

Managing Diagnostic Logs

When troubleshooting complex issues, an operator often needs to collect and analyze detailed diagnostic logs from the Azure Stack Hub infrastructure. The AZ-600 curriculum covers the procedures for managing these logs. The operator can collect logs on demand through the administrator portal. This process gathers logs from all the relevant infrastructure components and packages them into a single zip file for analysis or for sharing with Microsoft support.

For more advanced scenarios, logs can be collected using the privileged endpoint (PEP). This method provides more options and can be used even if the administrator portal is unavailable. An AZ-600 professional must know the PowerShell cmdlets used in the PEP to start and stop the log collection process. They should also understand the different types of logs that can be collected to narrow down the scope of a problem.

To enable proactive and centralized log analysis, an operator can configure automatic diagnostic log collection. This feature can be configured to send the logs to a storage account in Azure or to an on-premises Syslog server. Configuring Syslog forwarding is a key skill, as it allows the Azure Stack Hub logs to be integrated with an organization's existing Security Information and Event Management (SIEM) system. This provides a unified view of security and operational events across the entire IT landscape, which is a best practice for enterprise operations.

Planning for Business Continuity and Disaster Recovery (BCDR)

Ensuring the resilience of the Azure Stack Hub and the tenant workloads it hosts is a critical responsibility for an operator. The AZ-600 exam places a strong emphasis on business continuity and disaster recovery (BCDR). The operator must be able to recommend a BCDR strategy that covers both the infrastructure itself and the tenant applications. For tenant workloads, the strategy might involve leveraging Azure Site Recovery for replication to Azure or to a secondary site, or using backup solutions that are compatible with Azure Stack Hub VMs.

A key part of the infrastructure protection strategy is managing the BitLocker recovery keys for the storage volumes. Azure Stack Hub uses BitLocker to encrypt all data at rest. In the event of a catastrophic failure and system recovery, these keys are required to access the data. An AZ-600 professional must know the procedure for securely retrieving and storing these recovery keys from the privileged endpoint. Losing these keys could result in a total loss of data.

The most important BCDR feature for the infrastructure is the infrastructure backup service. An operator must know how to configure this service to back up the critical configuration data of the Azure Stack Hub, such as the identity and service configuration. This backup does not include tenant data but is essential for recovering the system to a known good state after a failure. An AZ-600 candidate must be an expert in planning and configuring these infrastructure backups.

Configuring and Managing Infrastructure Backups

A core operational task covered by the AZ-600 exam is the configuration and management of infrastructure backups. The operator must choose and configure a storage target for these backups. This can be an external SMB file share, which must be highly available and have sufficient capacity. The operator needs to provide the path to the share and the credentials needed to access it. They must also configure the frequency of the backups and the retention policy for how long the backups are kept.

Security for the backup process is also a key consideration. The data transfer to the backup share can be encrypted, and the backups themselves are encrypted at rest on the share. This requires the operator to configure a certificate for the backup service to ensure the confidentiality and integrity of the backup data. An AZ-600 certified professional must understand these security settings and be able to implement them according to best practices.

Once configured, the operator must monitor the success of the backup jobs. They can validate the status of backups through the administrator portal or by using PowerShell. Periodically testing the backup and restore process is a crucial part of any BCDR strategy. While a full restore is a major operation, an AZ-600 candidate should be familiar with the process, which can be practiced and validated using the Azure Stack Development Kit (ASDK), a single-node version of Azure Stack Hub.

Performing Node and System-Wide Operations

The AZ-600 curriculum covers a range of operational tasks related to managing the physical nodes and the overall system. As an organization's needs grow, an operator may need to add new nodes to the Azure Stack Hub to increase its capacity and performance. This is a coordinated activity performed with the hardware vendor, but the operator is responsible for initiating the process and validating the successful addition of the new capacity.

Managing storage capacity is an ongoing task. An operator needs to monitor storage consumption and be able to perform operations to reclaim space or rebalance storage across the system. They may also need to add new public IP pools if the initial range becomes exhausted. These capacity management tasks are essential for preventing service disruptions caused by resource exhaustion, and an AZ-600 professional must be proficient in them.

Other system-wide operations include stopping and starting the entire Azure Stack Hub. This is a controlled and lengthy process that should only be done for planned maintenance, such as a datacenter-wide power down. The AZ-600 exam requires a candidate to know the correct procedure for this shutdown and startup to avoid data corruption or service impact. They must also know how to configure system-level settings like the NTP time server, external DNS forwarders, and the Syslog server for log forwarding.

Managing Updates for AZ-600

Keeping the Azure Stack Hub up to date is one of the most important and regular tasks for an operator. The AZ-600 exam thoroughly tests a candidate's knowledge of the end-to-end update process. Microsoft releases regular update packages that include the latest security patches, bug fixes, and new features for both the underlying operating system and the Azure Stack Hub software. The operator is responsible for downloading these packages, preparing the system, and applying the updates.

The update process is managed through the administrator portal. The operator can view available updates, run a readiness check to ensure the system is healthy enough to be updated, and then schedule and initiate the update. The update process is designed to be resilient and to minimize downtime for tenant workloads by updating one physical node at a time in a rolling fashion. An AZ-600 professional must be able to monitor the progress of the update and troubleshoot any issues that may cause it to fail.

Troubleshooting a failed update requires a logical approach. The operator would need to review the update logs, identify the point of failure, and take corrective action. This might involve working with the hardware vendor or Microsoft support. A deep understanding of the update architecture and the various stages of the process is essential. The AZ-600 certification validates that an operator has the skills to manage this critical lifecycle management task, ensuring the platform remains secure, stable, and supported.

Using the Privileged Endpoint (PEP)

The privileged endpoint, or PEP, is a critical tool for advanced administration and troubleshooting, and mastery of it is a key differentiator for an AZ-600 certified professional. The PEP is a set of restricted PowerShell endpoints on the Emergency Recovery Console VMs. It is not used for daily management but is essential for tasks that require low-level access to the infrastructure. A candidate must know how to securely connect to a PEP session from a hardened workstation.

Once connected, the operator can perform a range of powerful operations. This includes collecting advanced diagnostic logs, retrieving BitLocker recovery keys, and rotating the infrastructure PKI certificates. The PEP is also used to unlock a support session, which allows Microsoft support engineers to have temporary, authorized access to the system for deep troubleshooting. An AZ-600 professional must understand the process for granting and revoking this access securely.

The commands available in the PEP are specific and well-documented. An operator is not expected to memorize all of them but should be familiar with the key cmdlets for common advanced tasks. They must also understand the importance of closing the PEP session properly when their work is complete to maintain the security posture of the system. The ability to use the PEP confidently and responsibly is a hallmark of a senior Azure Stack Hub operator and is a vital skill validated by the AZ-600 exam.
