VMware 2V0-21.23 Exam Dumps & Practice Test Questions

Question 1:

An administrator is responsible for updating a vSphere cluster running vSAN using vSphere Lifecycle Manager. The update process should minimize downtime for the ESXi hosts. The administrator has already downloaded the necessary software, created a new image, attached this image to the cluster, checked cluster compliance, and completed a remediation pre-check without errors.

What two steps should the administrator take next to begin the cluster remediation using the new image? (Choose two.)

A. Use the Remediate option in vSphere Lifecycle Manager to update all ESXi hosts in the cluster simultaneously and let vSphere Lifecycle Manager manage maintenance mode automatically.
B. Manually place each ESXi host into maintenance mode, then stage the update software on each host one by one.
C. Keep all ESXi hosts operational and use the Stage All option in vSphere Lifecycle Manager to stage updates one host at a time.
D. Keep all ESXi hosts operational and use the Stage All option to stage updates on all hosts in parallel.
E. Use the Remediate option to update ESXi hosts one after another and allow vSphere Lifecycle Manager to control maintenance mode automatically.

Correct answers: A, E

Explanation:

When applying updates to a vSphere cluster running vSAN, the goal is to minimize downtime and ensure the update process is as seamless as possible. The administrator has already completed initial preparation steps such as creating the new image, attaching it, and running compliance and pre-checks.

The next critical step is remediation, which involves applying the updates to each ESXi host. Options A and E both use the Remediate feature of vSphere Lifecycle Manager, which automates the update process and maintenance mode management for the hosts. This is important because it eliminates manual errors and reduces operational overhead.

Option A suggests remediating all hosts in parallel. This approach updates multiple hosts concurrently, minimizing the total downtime for the cluster. This is beneficial in environments where reducing downtime is crucial, and parallel remediation is safe and supported.

Option E recommends remediating hosts sequentially, which means updating one host at a time. This method can be preferable in environments where stability is critical and there are concerns about running simultaneous updates, as it allows for closer control and easier troubleshooting if issues arise.

Options B, C, and D are less optimal. Manual placement into maintenance mode (B) increases the risk of human error and slows the process. Staging updates without applying them (C and D) prepares the software but does not complete the remediation. Also, staging updates one host at a time (C) is inefficient, and while staging in parallel (D) speeds preparation, it doesn't handle the actual update application.

In conclusion, using the Remediate option with automatic maintenance mode management ensures an efficient, low-downtime update process. Whether remediation happens in parallel or sequence depends on the environment’s tolerance for risk and downtime.

Question 2:

An administrator needs to provide log bundles from ESXi hosts for VMware Support. Which three methods can the administrator use to generate these log bundles? (Choose three.)

A. Use the vCenter Management Interface to generate a combined log bundle for all ESXi hosts.
B. Use the vSphere Host Client to generate individual log bundles for each ESXi host.
C. Use the vSphere Client to generate a combined log bundle for all ESXi hosts.
D. Use the vSphere Client to generate individual log bundles for each ESXi host.
E. Use the vCenter Management Interface to generate separate log bundles for each ESXi host.
F. Use the vSphere Host Client to generate a combined log bundle for all ESXi hosts.

Correct answers: B, D, E

Explanation:

When VMware Support requests log bundles for troubleshooting, the administrator can collect these logs using various management interfaces, but there are important distinctions in how these logs are generated and combined.

Options B, D, and E represent valid ways to generate log bundles per host, which is typically what VMware Support requires for accurate diagnostics:

• Option B: The vSphere Host Client allows direct connection to an individual ESXi host, from which the administrator can generate a separate log bundle. This is useful for granular, host-specific issues.

• Option D: The vSphere Client also provides the capability to generate logs per host, giving flexibility to administrators working in environments managed centrally through vCenter.

• Option E: The vCenter Management Interface (vCenter Server) enables administrators to create separate log bundles for each ESXi host under its management. This is particularly useful when multiple hosts need logs collected simultaneously but separately.

Options A, C, and F mention generating combined log bundles across multiple hosts, which is generally not supported natively through these interfaces:

• Option A is incorrect because vCenter does not provide an option to create a single combined log bundle covering all hosts.

• Option C is incorrect for the same reason; the vSphere Client doesn’t provide an option for combined bundles across hosts.

• Option F is incorrect because the vSphere Host Client is host-specific and cannot generate combined bundles.

Collecting individual log bundles ensures that VMware Support receives precise information related to each host’s status and events, which improves troubleshooting accuracy. Centralized combined bundles, while theoretically convenient, are not standard practice or supported through these interfaces.

In summary, the administrator should rely on host-level log bundle generation via the vSphere Host Client, vSphere Client, or vCenter Management Interface to meet VMware Support’s needs effectively.

Question 3:

An administrator wants to reduce the number of physical servers by migrating their workloads to a software-defined data center platform. Which VMware product should be recommended to achieve this?

A. VMware Horizon
B. VMware vSAN
C. VMware vSphere
D. VMware NSX

Answer: C

Explanation:

The administrator’s goal is to consolidate physical servers by migrating workloads into a software-defined data center (SDDC). This requires a solution that provides server virtualization, centralized management, and resource consolidation. Evaluating each option:

• VMware Horizon is designed for virtual desktop infrastructure (VDI). It enables the delivery of virtual desktops and applications to end users but does not focus on server workload migration or physical server consolidation. Hence, Horizon is not suitable here.

• VMware vSAN is a software-defined storage solution that aggregates local storage from physical servers into a shared storage pool. It works alongside virtualization platforms to deliver scalable, resilient storage but does not manage compute resource virtualization or workload migration by itself.

• VMware vSphere is the fundamental virtualization platform enabling server consolidation. It includes the ESXi hypervisor for running virtual machines and vCenter Server for centralized management. vSphere virtualizes CPU, memory, and storage resources of physical servers, enabling administrators to migrate workloads into virtual machines efficiently. It is the primary enabler of software-defined data centers.

• VMware NSX focuses on network virtualization and security, providing software-defined networking capabilities such as virtual switches, firewalls, and load balancing. NSX is essential for SDDC networking but does not perform workload consolidation or compute virtualization.

In summary, VMware vSphere offers the core capabilities needed for consolidating physical servers and migrating their workloads into a virtualized environment. It manages compute virtualization and resource allocation across the data center, making it the best recommendation for this use case.

Question 4:

Which two types of adapters should an administrator set up to enable Remote Direct Memory Access (RDMA) over Converged Ethernet version 2 (RoCE v2)? (Select two.)

A. Paravirtual RDMA adapter
B. RDMA network adapter
C. Software iSCSI adapter
D. Fibre Channel over Ethernet (FCoE) adapter
E. Software NVMe over RDMA storage adapter

Answer: B, E

Explanation:

RDMA over Converged Ethernet v2 (RoCE v2) enables high-speed, low-latency communication by allowing direct memory access between devices across Ethernet networks without involving the CPU heavily. This enhances throughput and reduces latency, which is critical for performance-sensitive storage and networking workloads.

• The RDMA network adapter (B) is a hardware component that supports RDMA protocols on Ethernet networks. It is essential for RoCE v2 because it enables direct memory access functionality at the network layer, bypassing the kernel and reducing CPU overhead.

• The Software NVMe over RDMA storage adapter (E) is required in environments where NVMe storage devices use RDMA for communication. NVMe over RDMA is a protocol optimized for low-latency access to storage devices over the network. When combined with RoCE v2, this adapter allows efficient use of RDMA capabilities for storage access.

Other options do not fit this context:

• The Paravirtual RDMA adapter (A) is a virtual adapter typically used inside virtual machines to facilitate RDMA-like functionality but is not a physical adapter required to support RoCE v2.

• The Software iSCSI adapter (C) uses TCP/IP to access storage over the network but does not utilize RDMA, thus not suitable for RoCE v2, which requires RDMA-capable hardware.

• The FCoE adapter (D) is used for Fibre Channel over Ethernet SANs, which is a different technology stack and does not implement RDMA or RoCE.

Therefore, the correct setup to enable RDMA over RoCE v2 involves configuring both the RDMA network adapter and the Software NVMe over RDMA storage adapter to maximize performance and protocol compatibility.

Question 5:

What action should an administrator take to apply a storage configuration change from the Standard-Config host profile to multiple other host profiles?

A. Export customizations from the host and import them into other host profiles.
B. Manually copy the storage settings from Standard-Config to other host profiles.
C. Duplicate the Standard-Config host profile and then modify the storage settings only.
D. Export the Standard-Config host profile and attach it to the other hosts.

Answer: D

Explanation:

When an administrator needs to apply storage configuration changes defined in one host profile (Standard-Config) to other hosts, the process should ensure consistency, minimize errors, and be scalable. Let’s analyze the options:

• Option A (exporting customizations and importing them) is too broad and might import unwanted settings or miss the precise storage settings. It lacks the precision needed for replicating a specific configuration like storage settings.

• Option B (manually copying settings) is error-prone and inefficient, especially when multiple hosts or profiles are involved. Manual processes increase the risk of inconsistencies and misconfigurations.

• Option C (duplicating the Standard-Config profile and modifying storage) creates additional profiles rather than applying the existing profile’s configuration to other hosts. This approach complicates management and doesn’t propagate the desired configuration to existing profiles or hosts.

• Option D (exporting the Standard-Config host profile and attaching it to other hosts) is the recommended and streamlined method. Exporting the profile packages the exact configuration, including storage settings, into a reusable profile. By attaching this profile to other hosts, the administrator enforces the configuration uniformly. This method reduces manual errors, ensures consistency, and simplifies the management of multiple hosts with identical storage configurations.

In conclusion, exporting the Standard-Config host profile and attaching it to the other hosts is the best practice to apply consistent storage settings efficiently across multiple host profiles.

Question 6:

In a vSphere cluster running both Production and Test virtual machines (VMs), where Distributed Resource Scheduler (DRS) is enabled but no resource pools exist, performance monitoring shows that Production VMs are not receiving their full memory allocation during peak cluster usage. 

Which two actions should the administrator take to guarantee that Production VMs always have their full memory allocation? (Choose two.)

A. Set a custom memory share value on the resource pool containing Production VMs.
B. Apply a memory reservation to the resource pool containing Production VMs.
C. Create a parent resource pool specifically for the Production VMs.
D. Create separate sibling resource pools for Production and Test VMs.
E. Create a child resource pool for the Test VMs.

Answer: B, C

Explanation:

When managing resource allocation in a vSphere cluster, particularly where Production workloads must be prioritized, the use of resource pools and memory reservations is critical to ensure guaranteed resource availability.

Why B is Correct:
Assigning a memory reservation to the resource pool that contains Production VMs guarantees a minimum amount of memory is always reserved for those VMs. This reservation ensures that even under high resource contention, the Production VMs will not be starved of their allocated memory. Without such a reservation, the system can oversubscribe memory, risking the performance of critical Production workloads.

Why C is Correct:
Creating a parent resource pool for the Production VMs helps group those VMs together, allowing the administrator to apply reservations, limits, and shares collectively. This structural organization provides better control over resource distribution and ensures that the Production group receives priority access to resources, especially during periods of cluster strain.

Why Other Options Are Not Optimal:

• A: Memory shares only influence resource priority during contention but do not guarantee minimum resource amounts. Hence, shares alone cannot assure full memory allocation under heavy load.

• D: Creating sibling pools segregates workloads but doesn't guarantee resource availability without reservations.

• E: Child pools for Test VMs do not address guaranteeing memory for Production VMs and thus don’t solve the core problem.

In summary, combining a parent resource pool (to group and manage Production VMs) with a memory reservation (to guarantee their memory) ensures Production VMs receive their full allocation at all times, making B and C the best solutions.

Question 7:

Which two datastore types store virtual machine components as individual objects rather than traditional files? (Choose two.)

A. VMware Virtual Machine File System (VMFS)
B. VMware vSAN
C. Network File System (NFS) version 3
D. vSphere Virtual Volumes (vVols)
E. Network File System (NFS) version 4.1

Answer: B, D

Explanation:

Virtual machines (VMs) in VMware environments consist of multiple components such as virtual disks, snapshots, and configuration files. How these components are stored depends heavily on the type of datastore used. Some datastores store VM components as traditional files, while others use an object-based approach, managing each component as an independent object.

Why B is Correct:
VMware vSAN is a distributed storage system that manages VM components as objects. Each VM disk or snapshot is represented as a discrete object within the vSAN datastore. This object-based model enables features such as efficient storage management, redundancy, and policy-driven automation. Because vSAN treats components individually, it allows more granular control and optimization.

Why D is Correct:
vSphere Virtual Volumes (vVols) introduces an object-centric storage architecture that offloads VM component management to the storage array. Each VM element—like disks, snapshots, and metadata—is stored as a separate object on compatible storage hardware. This model enhances storage integration and flexibility, allowing storage arrays to manage VM data more intelligently.

Why Other Options Are Incorrect:

• A (VMFS): VMFS is a traditional block-level file system that stores VM files as hierarchical files, not as independent objects.

• C and E (NFS 3 and NFS 4.1): Both NFS versions provide file-based storage over the network. VM components are stored as files within directories, not as objects, so they lack the fine-grained object-level management seen in vSAN and vVols.

To conclude, the object-based datastore types that store VM components as independent objects are VMware vSAN and vSphere Virtual Volumes (vVols), making B and D the correct answers.

Question 8:

After modifying a predefined alarm in VMware vCenter, an administrator activates email notifications, but no emails are being sent. 

Where should the administrator configure the mail server settings to ensure notifications are properly sent?

A. In the ESXi host system configuration
B. Within the alarm rule itself
C. In the vCenter settings via the vSphere Client
D. Through the vCenter Management Interface

Answer: C

Explanation:

When an administrator updates a predefined alarm and enables email notifications in VMware vCenter, but the emails fail to send, the root cause usually lies in the mail server settings not being correctly configured. The key place to set the SMTP (mail) server settings is within the vCenter Server configuration accessed through the vSphere Client.

Option A (ESXi host system config) refers to settings on individual ESXi hosts, such as hardware, network, or storage configurations. While ESXi hosts can send email alerts for certain host-level events, email notifications tied to vCenter alarms are managed centrally and not configured per host. So, this option won’t resolve the problem.

Option B (alarm rule definition) involves setting the conditions and actions for when the alarm triggers. Although enabling email notifications is part of the alarm’s configuration, the actual SMTP server details—such as server address, port, credentials—are not set here. This means the alarm depends on global mail server settings to send emails.

Option C is correct because the vCenter settings in the vSphere Client provide a centralized place to enter the SMTP mail server configuration. Here, the administrator can specify the mail server’s hostname or IP address, port, authentication info, and the sender’s email address. Without these details, enabling email notifications on alarms will have no effect, as vCenter doesn’t know where or how to send the emails.

Option D (vCenter Management Interface) is used mainly for server health monitoring and management tasks, not for setting up email servers for alarms.

In summary, the administrator must configure the mail server settings within the vCenter settings accessed via the vSphere Client to enable proper email notifications from alarms.

Question 9:

An administrator has created a virtual machine with all company-approved software and security patches. The company policy requires that only full clones be used for server workloads. 

Which two steps should the administrator take to prepare this VM for deployment to multiple users? (Choose two.)

A. Assign appropriate permissions on the VM
B. Create a virtual machine customization specification
C. Upgrade the virtual hardware
D. Convert the VM into a template
E. Take a snapshot of the VM

Answer: B, D

Explanation:

In preparing a virtual machine (VM) for deployment to multiple users under a policy mandating full clones for server workloads, two critical steps are involved to ensure efficient and conflict-free deployment: creating a customization specification and converting the VM to a template.

Option B is essential because a customization specification enables the administrator to tailor each clone after deployment. This includes setting unique hostnames, IP addresses, and network configurations to avoid conflicts between the multiple cloned VMs. Without customization, all clones would be identical, causing network conflicts and operational issues.

Option D involves converting the VM into a template. Templates act as master copies for deployment, allowing quick and consistent creation of multiple full clones. This ensures that each deployed VM is based on the same approved configuration, aligning with the company’s policy and simplifying management.

Option A (setting permissions) is a good security practice but is not directly part of the cloning or deployment preparation. Permissions can be assigned after cloning.

Option C (upgrading virtual hardware) might be necessary if newer hardware features are needed, but it’s unrelated to preparing a VM for cloning or ensuring compliance with the company’s full clone policy.

Option E (taking a snapshot) is primarily for backup or recovery purposes and does not facilitate deployment of full clones. Snapshots do not substitute templates for efficient cloning.

In conclusion, to meet the policy and deploy the VM efficiently to multiple users, the administrator should create a customization specification and convert the VM to a template.

Question 10:

During a patch staging process from the vCenter Management Interface, an error occurs and interrupts the operation. 

What should the administrator do to continue the process from the point of failure?

A. Select "Stage and Install" to restart the process
B. Select "Resume" to continue staging
C. Select "Unstage" to restart the staging
D. Select "Stage Only" to restart the staging

Answer: B

Explanation:

When patch staging is interrupted due to an error, the vCenter Server Appliance provides options to manage the patching workflow. The goal is to continue patch staging from the point of failure without starting over entirely.

Option B, the "Resume" option, is designed specifically for this situation. It allows the administrator to pick up the staging process exactly where it stopped due to the error. This avoids repeating previously completed steps, saving time and preventing redundant actions that could cause conflicts or additional errors.

Option A (Stage and Install) restarts both the staging and installation phases. Using this after an interruption is inefficient because it unnecessarily repeats actions already completed, increasing downtime and risk of errors.

Option C (Unstage) reverses or removes staged patches. It is used when rolling back changes, not for continuing a paused or failed staging process.

Option D (Stage Only) initiates the staging process from scratch. This is like starting over and doesn’t allow continuation from the failure point.

Thus, to efficiently resolve the patch staging interruption, the administrator should use the "Resume" option. This function continues the process smoothly from the error point without restarting the entire operation.
