Question 450
A private internal ASE application becomes unreachable after its subnet routing and NSG policy were changed. A review identifies this consequence: Applying arbitrary subnet restrictions can prevent required ASE platform communication. Which remediation most directly restores the intended behavior?
- The controlled remediation is to block every platform communication path without checking ASE documentation.
- The controlled remediation is to deploy an ASE into a subnet already consumed by unrelated incompatible services.
- The controlled remediation is to restore supported network requirements and verify internal and external exposure matches policy.
- The controlled remediation is to assume the App Service plan alone enforces all subnet-based isolation.
Explanation
Correct Answer
C:Test using these records: ASE deployment and ingress mode, subnet NSG rules, DNS and deployment health. An App Service Environment provides an isolated hosting environment with platform-specific subnet and ingress requirements.
Incorrect Answers
A:Block every platform communication path without checking ASE documentation. This would not reliably restore the intended security boundary. Applying arbitrary subnet restrictions can prevent required ASE platform communication. The appropriate controlled recovery is: Restore supported network requirements and verify internal and external exposure matches policy.
B:Deploy an ASE into a subnet already consumed by unrelated incompatible services. This would not reliably restore the intended security boundary. Applying arbitrary subnet restrictions can prevent required ASE platform communication. The appropriate controlled recovery is: Restore supported network requirements and verify internal and external exposure matches policy.
D:Assume the App Service plan alone enforces all subnet-based isolation. This would not reliably restore the intended security boundary. Applying arbitrary subnet restrictions can prevent required ASE platform communication. The appropriate controlled recovery is: Restore supported network requirements and verify internal and external exposure matches policy.
Question 451
An Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths. Which configuration decision MOST directly resolves the issue?
- Treat Managed Instance like a VM with no delegated subnet constraints.
- Review the SQL Managed Instance subnet requirements and configure supported NSG and route policies.
- Apply arbitrary forced routes and deny every required platform port.
- Disable database auditing to troubleshoot subnet routing.
Explanation
Correct Answer
B:Confirm the change against these records: Managed instance service health, subnet delegation, effective NSG, route table and connectivity. This directly addresses Azure SQL Managed Instance network rules.
Incorrect Answers
A:Blocking required platform traffic can disrupt managed instance operations or client connectivity. In the given case, an Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths.
C:Apply arbitrary forced routes and deny every required platform port. The proposed change targets the wrong mechanism or lacks essential validation. Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules. Relevant evidence is managed instance service health, subnet delegation, effective NSG, route table and connectivity.
D:Blocking required platform traffic can disrupt managed instance operations or client connectivity. The intended action is: Review the SQL Managed Instance subnet requirements and configure supported NSG and route policies.
Question 452
An Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths. What evidence most directly confirms the intended security behavior?
- A public DNS response that does not show the intended private service path.
- A static virtual network diagram with no effective route or packet observation.
- A healthy network interface without the evaluated NSG, route or private endpoint.
- Managed instance service health, subnet delegation, effective NSG, route table and connectivity.
Explanation
Correct Answer
D:These records test the actual Azure SQL Managed Instance network rules behavior rather than an unrelated dashboard state. Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules.
Incorrect Answers
A:On its own, that evidence does not prove the specified security control works. The more relevant observations are: Managed instance service health, subnet delegation, effective NSG, route table and connectivity.
B:On its own, that evidence does not prove the specified security control works. Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules.
C:On its own, that evidence does not prove the specified security control works. In the given case, an Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths.
Question 453
An Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths. Which security principle best explains the intended decision?
- Creating a virtual network peering link makes all other Azure VNets transitively reachable.
- An NSG allow is sufficient even when another relevant security layer explicitly denies the flow.
- Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules.
- Successful public name resolution proves that all traffic uses Private Link.
Explanation
Correct Answer
C:Confirmation depends on Managed instance service health, subnet delegation, effective NSG, route table and connectivity. This principle supports the security response: Review the SQL Managed Instance subnet requirements and configure supported NSG and route policies.
Incorrect Answers
A:Creating a virtual network peering link makes all other Azure VNets transitively reachable. This is an incorrect assumption for Azure SQL Managed Instance network rules. The relevant security behavior is: Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules.

Question 454
An Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths. Suppose the operator instead follows this unsafe shortcut: Treat Managed Instance like a VM with no delegated subnet constraints. Which resulting risk or fault should the reviewer identify?
- The investigation itself created the pre-existing private DNS or route mismatch.
- The failure consists only of retaining valid network flow logs.
- Blocking required platform traffic can disrupt managed instance operations or client connectivity.
- A VNet diagram label alone explains the blocked or uninspected traffic.
Explanation
Correct Answer
C:The suitable control is: Review the SQL Managed Instance subnet requirements and configure supported NSG and route policies. This is a material consequence of the incorrect shortcut.
Incorrect Answers
A:This does not explain the real Azure SQL Managed Instance network rules weakness after the shortcut. The material failure is: Blocking required platform traffic can disrupt managed instance operations or client connectivity.
B:This does not explain the real Azure SQL Managed Instance network rules weakness after the shortcut. Inspect evidence such as managed instance service health, subnet delegation, effective NSG, route table and connectivity.
D:This does not explain the real Azure SQL Managed Instance network rules weakness after the shortcut. In the given case, an Azure SQL Managed Instance becomes unavailable after a subnet NSG blocks its required management and database paths.
