Microsoft AZ-500 Practice Test 47
Question 460
A SQL Managed Instance service in a delegated subnet loses connectivity when engineers force all traffic through an unsupported route. A review identifies this consequence: Blocking required platform traffic can disrupt managed instance operations or client connectivity. Which recovery action restores the intended control and validates its effect?
- The controlled remediation is to disable database auditing to troubleshoot subnet routing.
- The controlled remediation is to treat Managed Instance like a VM with no delegated subnet constraints.
- The controlled remediation is to apply arbitrary forced routes and deny every required platform port.
- The controlled remediation is to restore the supported delegated subnet design and retest private SQL sessions.
Explanation
Correct Answer
D:Test using these records: Managed instance service health, subnet delegation, effective NSG, route table and connectivity. Azure SQL Managed Instance has network and delegation requirements beyond ordinary VM subnet rules.
Incorrect Answers
A:Disable database auditing to troubleshoot subnet routing. This would not reliably restore the intended security boundary. Blocking required platform traffic can disrupt managed instance operations or client connectivity. The appropriate controlled recovery is: Restore the supported delegated subnet design and retest private SQL sessions.
B:Treat Managed Instance like a VM with no delegated subnet constraints. This would not reliably restore the intended security boundary. Blocking required platform traffic can disrupt managed instance operations or client connectivity. The appropriate controlled recovery is: Restore the supported delegated subnet design and retest private SQL sessions.
C:Apply arbitrary forced routes and deny every required platform port. This would not reliably restore the intended security boundary. Blocking required platform traffic can disrupt managed instance operations or client connectivity. The appropriate controlled recovery is: Restore the supported delegated subnet design and retest private SQL sessions.
Question 461
A web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter. Which operator action best meets this technical requirement?
- Deploy Azure Application Gateway with an appropriate WAF policy and validated listener and backend routing.
- Use only an NSG to inspect SQL injection payloads in HTTP bodies.
- Enable a plain load balancer and call it a web application firewall.
- Permit every backend HTTP request to bypass WAF for simpler routing.
Explanation
Correct Answer
A:Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering. Confirm the change against these records: WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
Incorrect Answers
B:An ordinary network load balancer does not automatically apply OWASP-style HTTP protection. Use only an NSG to inspect SQL injection payloads in HTTP bodies.
C:Enable a plain load balancer and call it a web application firewall. The proposed change targets the wrong mechanism or lacks essential validation. Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering. Relevant evidence is WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
D:An ordinary network load balancer does not automatically apply OWASP-style HTTP protection. The intended action is: Deploy Azure Application Gateway with an appropriate WAF policy and validated listener and backend routing.
Question 462
A web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter. Which collection of observations most directly tests the suspected cause?
- A successful connection to a different address and different service port.
- The name of a firewall policy without its applied match and request logs.
- WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
- A static virtual network diagram with no effective route or packet observation.
Explanation
Correct Answer
C:These records test the actual application Gateway WAF inspection behavior rather than an unrelated dashboard state. Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering.
Incorrect Answers
A:On its own, that evidence does not prove the specified security control works. The more relevant observations are: WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
B:On its own, that evidence does not prove the specified security control works. Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering.
D:On its own, that evidence does not prove the specified security control works. In the given case, a web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter.
Question 463
A web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter. Which statement most accurately explains this scenario?
- A network appliance presence guarantees the effective route traverses it.
- Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering.
- Creating a virtual network peering link makes all other Azure VNets transitively reachable.
- An HTTP load balancer automatically inspects every malicious request as a WAF.
Explanation
Correct Answer
B:Confirmation depends on WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests. This principle supports the security response: Deploy Azure Application Gateway with an appropriate WAF policy and validated listener and backend routing.
Incorrect Answers
A:A network appliance presence guarantees the effective route traverses it. This is an incorrect assumption for application Gateway WAF inspection. The relevant security behavior is: Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering. Check evidence such as WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
C:Creating a virtual network peering link makes all other Azure VNets transitively reachable. This is an incorrect assumption for application Gateway WAF inspection.

Question 464
A web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter. Suppose the operator instead follows this unsafe shortcut: Use only an NSG to inspect SQL injection payloads in HTTP bodies. What is the principal technical consequence of the mistaken choice?
- A VNet diagram label alone explains the blocked or uninspected traffic.
- Changing a resource description fixes every underlying transport rule.
- An ordinary network load balancer does not automatically apply OWASP-style HTTP protection.
- The root problem was using a permitted endpoint reachability test.
Explanation
Correct Answer
C:Application Gateway WAF inspects Layer 7 web requests and is distinct from general IP and port filtering. This is a material consequence of the incorrect shortcut.
Incorrect Answers
A:This does not explain the real application Gateway WAF inspection weakness after the shortcut. The material failure is: An ordinary network load balancer does not automatically apply OWASP-style HTTP protection.
B:This does not explain the real application Gateway WAF inspection weakness after the shortcut. Inspect evidence such as WAF policy match, listener configuration, backend health and blocked versus allowed HTTP requests.
D:This does not explain the real application Gateway WAF inspection weakness after the shortcut. The root problem was using a permitted endpoint reachability test.
Question 465
A web application receives malicious HTTP request payloads despite using a load balancer with no application-layer filter.
