Question 190
After a backend maintenance window, Application Gateway still sends new traffic to one stale instance because the pool membership was not updated. A backend API needs a nonstandard HTTP port and the gateway reports connection failures though client port 443 is healthy. What is the most appropriate plan for this situation?
- Update backend pool membership and probe configuration and verify traffic distribution from client requests; Set the backend HTTP port and probe destination correctly rather than changing the public HTTPS listener.
- Update backend pool membership and probe configuration and verify traffic distribution from client requests; use a supported layer-4 load balancer, Azure Bastion, or access method matched to the management protocol.
- Set the backend HTTP port and probe destination correctly rather than changing the public HTTPS listener; do not update backend pool membership and probe configuration and verify traffic distribution from client requests.
- Configure probes with the intended host header and path and validate the origin's virtual host behavior; Set the backend HTTP port and probe destination correctly rather than changing the public HTTPS listener.
Explanation
Correct Answer
A:Traffic destinations are determined by actual backend membership and health, not intended infrastructure state. Frontend and backend ports are independent settings in an application-layer proxy. Both actions are needed.
Incorrect Answers
B:Frontend and backend ports are independent settings in an application-layer proxy.
C:This plan leaves out a required action: Update backend pool membership and probe configuration and verify traffic distribution from client requests. The remaining action alone does not satisfy the situation.
D:Traffic destinations are determined by actual backend membership and health, not intended infrastructure state.
Question 191
An on-premises route learned over BGP overlaps a narrow spoke UDR, and the team cannot explain the chosen next hop. A network team deploys a virtual WAN hub and assumes ordinary VNet peering route tables govern all hub-to-branch connectivity. Which course of action addresses the stated issues?
- Add validated private-destination routes and appropriate return routing to direct authorized interspoke sessions through the NVA; review Virtual WAN hub routing, connection associations, and propagations instead of applying standard VNet hub assumptions.
- Compare effective routes and apply longest-prefix matching and route-source precedence to the specific destination; review the supported gateway-transit constraints and select a topology that uses an eligible gateway path consistently.
- Compare effective routes and apply longest-prefix matching and route-source precedence to the specific destination; review Virtual WAN hub routing, connection associations, and propagations instead of applying standard VNet hub assumptions.
- Review Virtual WAN hub routing, connection associations, and propagations instead of applying standard VNet hub assumptions; do not compare effective routes and apply longest-prefix matching and route-source precedence to the specific destination.
Explanation
Correct Answer
C:Route decisions depend on both prefix specificity and precedence; a default BGP path need not win against a more specific UDR. Virtual WAN has its own route-table and connection semantics that differ from manually peered hubs. Both actions are needed.

Question 192
An engineer expects NAT Gateway to translate private addresses for traffic between two private VNets without public internet egress. What should the Azure network engineer do?
- Inspect SNAT port consumption and design appropriate NAT Gateway capacity and connection reuse for the outbound workload.
- Review the documented outbound connectivity precedence and effective SNAT path for the actual subnet attachments.
- Attach Azure NAT Gateway with approved public IP resources to the workload subnet and validate outbound SNAT behavior.
- Use appropriate private routing or an NVA translation design because NAT Gateway is intended for outbound internet connectivity.
Explanation
Correct Answer
D:Subnet NAT Gateway is not a general private-to-private network address translation router.
Incorrect Answers
A:For this finding, subnet NAT Gateway is not a general private-to-private network address translation router.
B:Here, subnet NAT Gateway is not a general private-to-private network address translation router.
C:For this question, subnet NAT Gateway is not a general private-to-private network address translation router.
Question 193
An e-commerce site faces SQL injection in HTTP form fields but the security team relies solely on an L4 NSG port restriction. A web application needs global edge enforcement for geographically distributed users, but the team builds a WAF policy only on one regional internal Application Gateway. What is the most appropriate plan for this situation?
- Deploy WAF with supported managed rule sets on Application Gateway or Front Door and test malicious request handling; Start with detection-mode investigation and tune narrow rules or exclusions before moving to prevention.
- Associate the WAF policy at the supported gateway or listener scope and verify effective enforcement through logs; apply a supported Azure Front Door WAF policy to the global edge endpoint for eligible web traffic.
- Apply a supported Azure Front Door WAF policy to the global edge endpoint for eligible web traffic; do not deploy WAF with supported managed rule sets on Application Gateway or Front Door and test malicious request handling.
- Deploy WAF with supported managed rule sets on Application Gateway or Front Door and test malicious request handling; apply a supported Azure Front Door WAF policy to the global edge endpoint for eligible web traffic.
Explanation
Correct Answer
D:Web application attacks require application-layer inspection of HTTP payloads beyond port-level packet rules. Front Door WAF inspects eligible requests at global ingress, while Application Gateway is a regional web delivery service. Both actions are needed.
Incorrect Answers
A:Front Door WAF inspects eligible requests at global ingress, while Application Gateway is a regional web delivery service.
B:Web application attacks require application-layer inspection of HTTP payloads beyond port-level packet rules.
C:This plan leaves out a required action: Deploy WAF with supported managed rule sets on Application Gateway or Front Door and test malicious request handling. The remaining action alone does not satisfy the situation.
Question 194
An operations team configures an Azure Firewall network rule for web traffic but expects it to filter by individual HTTP URL path. A service hosted behind a firewall must be published to the internet through one approved public IP and translated to a private host. Which course of action addresses the stated issues?
- Configure Azure Firewall application rules for supported web protocols and destination domains; configure an Azure Firewall DNAT rule and corresponding backend routing and security controls.
- Use appropriate application-layer controls and select firewall rules based on supported L3–L7 matching capabilities; configure an Azure Firewall DNAT rule and corresponding backend routing and security controls.
- Configure an Azure Firewall DNAT rule and corresponding backend routing and security controls; do not use appropriate application-layer controls and select firewall rules based on supported L3–L7 matching capabilities.
- Use appropriate application-layer controls and select firewall rules based on supported L3–L7 matching capabilities; deploy Azure Firewall in a supported dedicated AzureFirewallSubnet and route approved flows through its private address.
Explanation
Correct Answer
B:Firewall network rules are based on network tuples; they do not act as full HTTP path-based web application proxies. Destination network address translation publishes an approved private target rather than creating generalized inbound permission. Both actions are needed.

Question 195
A Windows user sees a successful P2S tunnel but no DNS resolution for private service names despite correct IP connectivity. Which action best addresses this finding?
- Review Always On VPN client, authentication, and gateway prerequisites and map only supported Azure roles.
- Inspect certificate trust chains and authentication logs on both client and gateway before altering network routes.
- Provide supported custom DNS server or private resolution configuration through the client and gateway architecture.
- Check supported Azure Network Adapter OS and management prerequisites before recommending that onboarding path.
Explanation
Correct Answer
C:Remote VPN transport does not automatically supply access to the correct internal DNS namespace.
Incorrect Answers
A:Reviewing Always On VPN client, authentication, and gateway prerequisites and mapping only supported Azure roles would not provide supported custom DNS server or private resolution configuration through the client and gateway architecture.
B:For this finding, remote VPN transport does not automatically supply access to the correct internal DNS namespace.
D:Checking supported Azure Network Adapter OS and management prerequisites would not provide supported custom DNS server or private resolution configuration through the client and gateway architecture.
Question 196
A team configures Front Door WAF but the origin still accepts direct internet traffic from arbitrary clients. A subscription owner assumes every Front Door tier includes Private Link origins and WAF features at identical price and functionality. What is the most appropriate plan for this situation?
- Inspect origin group routing, priority, weight, and health settings and test representative client regions; select an appropriate Standard or Premium Front Door tier after mapping required features, limitations, and costs.
- Select an appropriate Standard or Premium Front Door tier after mapping required features, limitations, and costs; do not Harden the origin with suitable network access restrictions and verify that permitted ingress follows Front Door.
- Harden the origin with suitable network access restrictions and verify that permitted ingress follows Front Door; select an appropriate Standard or Premium Front Door tier after mapping required features, limitations, and costs.
- Harden the origin with suitable network access restrictions and verify that permitted ingress follows Front Door; evaluate supported Front Door Premium origin Private Link integration and validate the origin approval and routing.
Explanation
Correct Answer
C:Edge WAF cannot inspect or block requests that bypass the edge and reach an unprotected origin directly. Front Door feature availability and origin security options vary by tier and must be checked explicitly. Both actions are needed.
Incorrect Answers
A:Edge WAF cannot inspect or block requests that bypass the edge and reach an unprotected origin directly.
B:This plan leaves out a required action: Harden the origin with suitable network access restrictions and verify that permitted ingress follows Front Door. The remaining action alone does not satisfy the situation.

Question 197
An engineer creates a private DNS zone but never links it to the application VNet; clients resolve the name as nonexistent. Which response best addresses this Azure networking scenario?
- Enable supported auto-registration on the designated VNet link and verify which resource types produce records.
- Create an Azure Private DNS zone and link each participating VNet with the appropriate resolution settings.
- Host the external record in a publicly delegated Azure DNS zone or another authoritative public DNS provider.
- Link the relevant private zone to the querying VNet and test Azure-provided resolver behavior.
Explanation
Correct Answer
D:Creating a zone alone does not give a VNet permission or a route to resolve its records.
Incorrect Answers
A:Here, creating a zone alone does not give a VNet permission or a route to resolve its records.
B:Creating an Azure Private DNS zone and link each participating VNet with the appropriate resolution settings would not address the need for link the relevant private zone to the querying VNet and test Azure-provided resolver behavior.
C:DNS configuration would not address the need for link the relevant private zone to the querying VNet and test Azure-provided resolver behavior.
Question 198
A subnet reaches a supported service endpoint, but the service firewall denies requests because the VNet subnet was never allowed. An app on-premises must reach a storage account exclusively over a private IP but the architect suggests using only a VNet service endpoint. Which response best addresses these needs?
- Choose a private endpoint when the requirement is a private IP on the consumer VNet; use a Private Endpoint with hybrid DNS/routing, since service endpoints do not give an on-premises client a private consumer IP.
- Add the intended subnet to the service's supported network access rules and confirm the service endpoint state; enable the supported service endpoint on those subnets and configure matching storage firewall VNet rules.
- Use a Private Endpoint with hybrid DNS/routing, since service endpoints do not give an on-premises client a private consumer IP; do not add the intended subnet to the service's supported network access rules and confirm the service endpoint state.
- Add the intended subnet to the service's supported network access rules and confirm the service endpoint state; use a Private Endpoint with hybrid DNS/routing, since service endpoints do not give an on-premises client a private consumer IP.
Explanation
Correct Answer
D:Subnet endpoint activation alone does not grant the service permission to accept the subnet's requests. Service endpoints primarily identify Azure VNet subnets to supported Azure services and do not create on-premises private endpoints. Both actions are needed.
Incorrect Answers
A:Subnet endpoint activation alone does not grant the service permission to accept the subnet's requests.
B:Service endpoints primarily identify Azure VNet subnets to supported Azure services and do not create on-premises private endpoints.
C:This plan leaves out a required action: Add the intended subnet to the service's supported network access rules and confirm the service endpoint state. The remaining action alone does not satisfy the situation.
Question 199
A software provider hosts a custom TCP service behind an internal Standard Load Balancer and wants customers to connect without public exposure. A private-link provider changes its backend pool, then assumes all client endpoint connections must be recreated. What is the most appropriate plan for this situation?
- Create a supported Azure Private Link service backed by the load balancer and manage consumer endpoint approvals; publish the service through an eligible Private Link service or supported Azure service target first.
- Maintain the supported Private Link service frontend while updating backend health and routing as needed; do not create a supported Azure Private Link service backed by the load balancer and manage consumer endpoint approvals.
- Configure Private Link service visibility and connection approval permissions before accepting consumer requests; Maintain the supported Private Link service frontend while updating backend health and routing as needed.
- Create a supported Azure Private Link service backed by the load balancer and manage consumer endpoint approvals; Maintain the supported Private Link service frontend while updating backend health and routing as needed.
Explanation
Correct Answer
D:Private Link service publishes an eligible customer-hosted private service to consumers via their private endpoints. Consumer private endpoint connections target the published service, allowing controlled backend changes behind its stable contract. Both actions are needed.
Incorrect Answers
A:Consumer private endpoint connections target the published service, allowing controlled backend changes behind its stable contract.
B:This plan leaves out a required action: Create a supported Azure Private Link service backed by the load balancer and manage consumer endpoint approvals. The remaining action alone does not satisfy the situation.
C:Private Link service publishes an eligible customer-hosted private service to consumers via their private endpoints.
Question 200
A web application must maintain one stable inbound IP through a VM restart, but it currently receives a dynamic public address. Which response best addresses this Azure networking scenario?
- Evaluate Azure custom IP prefix bring-your-own-IP onboarding, validation, and supported regional advertisement requirements.
- Create a suitable static Standard public IP and associate it with the supported load balancer or network interface.
- Reserve a Standard public IP prefix of appropriate size and allocate individual public IP resources from that prefix.
- Create and explicitly assign appropriate public IP resources from the prefix to the intended frontend endpoints.
Explanation
Correct Answer
B:A static public IP resource maintains a known endpoint instead of relying on a temporary automatically assigned address.
Incorrect Answers
A:Here, a static public IP resource maintains a known endpoint instead of relying on a temporary automatically assigned address.
C:For this question, a static public IP resource maintains a known endpoint instead of relying on a temporary automatically assigned address.
D:Creating and explicitly assign appropriate public IP resources from the prefix to the intended frontend endpoints would not create a suitable static Standard public IP and associate it with the supported load balancer or network interface.
