Question 370
An organization needs consistent firewall governance across several secured virtual hubs and virtual networks. A review identifies this consequence: Unmanaged independent rule changes can create contradictory security behavior across regions. Which remediation most directly restores the intended behavior?
- The controlled remediation is to assume one custom DNS record centrally manages every firewall security rule.
- The controlled remediation is to assign the approved policies consistently and verify policy association and effective rules.
- The controlled remediation is to edit individual firewall instances without recording common policy changes.
- The controlled remediation is to replace all managed firewalls with NSG rules and call it equivalent inspection.
Explanation
Correct Answer
B:Test using these records: Firewall Manager deployment, associated Firewall Policies, inherited rules and regional log evidence. Central policy management helps apply consistent Azure Firewall controls across supported deployments.
Incorrect Answers
A:Assume one custom DNS record centrally manages every firewall security rule. This would not reliably restore the intended security boundary. Unmanaged independent rule changes can create contradictory security behavior across regions. The appropriate controlled recovery is: Assign the approved policies consistently and verify policy association and effective rules.
C:Edit individual firewall instances without recording common policy changes. This would not reliably restore the intended security boundary. Unmanaged independent rule changes can create contradictory security behavior across regions. The appropriate controlled recovery is: Assign the approved policies consistently and verify policy association and effective rules.
D:Replace all managed firewalls with NSG rules and call it equivalent inspection. This would not reliably restore the intended security boundary. Unmanaged independent rule changes can create contradictory security behavior across regions. The appropriate controlled recovery is: Assign the approved policies consistently and verify policy association and effective rules.
Question 371
A storage account is configured to accept traffic from an approved subnet using service endpoints but a VM in another subnet can still access it due to open storage firewall rules. Which configuration decision MOST directly resolves the issue?
- Assume service endpoint activation alone disables every public access path.
- Use a private DNS zone record as a substitute for the service endpoint network ACL.
- Open the storage account firewall to all networks to simplify endpoint deployment.
- Enable service endpoint on the subnet and apply the resource's virtual network firewall restrictions.
Explanation
Correct Answer
D:A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access. Confirm the change against these records: Subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
Incorrect Answers
A:Enabling an endpoint without restricting the PaaS account can leave broad network access. Assume service endpoint activation alone disables every public access path.
B:That option would use a private DNS zone record as a substitute for the service endpoint network ACL, but it addresses a different concern. A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access.
C:Enabling an endpoint without restricting the PaaS account can leave broad network access. The intended action is: Enable service endpoint on the subnet and apply the resource's virtual network firewall restrictions.
Question 372
A storage account is configured to accept traffic from an approved subnet using service endpoints but a VM in another subnet can still access it due to open storage firewall rules. What evidence most directly confirms the intended security behavior?
- A healthy network interface without the evaluated NSG, route or private endpoint.
- Subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
- A public DNS response that does not show the intended private service path.
- The name of a firewall policy without its applied match and request logs.
Explanation
Correct Answer
B:These records test the actual virtual network service endpoint restriction behavior rather than an unrelated dashboard state. A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access.
Incorrect Answers
A:On its own, that evidence does not prove the specified security control works. A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access.
C:On its own, that evidence does not prove the specified security control works. The more relevant observations are: Subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
D:On its own, that evidence does not prove the specified security control works. In the given case, a storage account is configured to accept traffic from an approved subnet using service endpoints but a VM in another subnet can still access it due to open storage firewall rules.
Question 373
A storage account is configured to accept traffic from an approved subnet using service endpoints but a VM in another subnet can still access it due to open storage firewall rules. Which security principle best explains the intended decision?
- Successful public name resolution proves that all traffic uses Private Link.
- A network appliance presence guarantees the effective route traverses it.
- An NSG allow is sufficient even when another relevant security layer explicitly denies the flow.
- A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access.
Explanation
Correct Answer
D:This principle supports the security response: Enable service endpoint on the subnet and apply the resource's virtual network firewall restrictions. Confirmation depends on Subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
Incorrect Answers
A:Successful public name resolution proves that all traffic uses Private Link. This is an incorrect assumption for virtual network service endpoint restriction. The relevant security behavior is: A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access. Check evidence such as subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
B:A network appliance presence guarantees the effective route traverses it. This is an incorrect assumption for virtual network service endpoint restriction. The relevant security behavior is: A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access. Check evidence such as subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
C:An NSG allow is sufficient even when another relevant security layer explicitly denies the flow. This is an incorrect assumption for virtual network service endpoint restriction.

Check evidence such as subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
Question 374
A storage account is configured to accept traffic from an approved subnet using service endpoints but a VM in another subnet can still access it due to open storage firewall rules. Suppose the operator instead follows this unsafe shortcut: Assume service endpoint activation alone disables every public access path. Which resulting risk or fault should the reviewer identify?
- The root problem was using a permitted endpoint reachability test.
- The investigation itself created the pre-existing private DNS or route mismatch.
- The failure consists only of retaining valid network flow logs.
- Enabling an endpoint without restricting the PaaS account can leave broad network access.
Explanation
Correct Answer
D:A service endpoint extends selected Azure service routing identity while destination service firewall rules still control access. This is a material consequence of the incorrect shortcut.
Incorrect Answers
A:This does not explain the real virtual network service endpoint restriction weakness after the shortcut. The material failure is: Enabling an endpoint without restricting the PaaS account can leave broad network access.
B:This does not explain the real virtual network service endpoint restriction weakness after the shortcut. Inspect evidence such as subnet endpoint configuration, resource network ACLs, authorized source and test connectivity.
C:This does not explain the real virtual network service endpoint restriction weakness after the shortcut. The failure consists only of retaining valid network flow logs.
