Question 350
A shared Firewall Policy rule group applies differently than expected after administrators changed collection priority. A review identifies this consequence: A broad earlier allow can undermine the intended more restrictive access design. Which recovery action addresses the underlying technical fault?
- The controlled remediation is to use a VM access review to determine Firewall Policy traffic matching.
- The controlled remediation is to assume a child policy always overrides a parent deny without checking precedence.
- The controlled remediation is to reorder or scope the policy rules and verify accepted and denied traffic.
- The controlled remediation is to delete all rule groups to test priority in production.
Explanation
Correct Answer
C:Azure Firewall Policy rule evaluation follows documented collection and parent-child precedence, not rule text order alone. Test using these records: Inherited Firewall Policy configuration, rule collection priority, rule match and traffic log.
Incorrect Answers
A:Use a VM access review to determine Firewall Policy traffic matching. This would not reliably restore the intended security boundary. A broad earlier allow can undermine the intended more restrictive access design. The appropriate controlled recovery is: Reorder or scope the policy rules and verify accepted and denied traffic.
B:Assume a child policy always overrides a parent deny without checking precedence. This would not reliably restore the intended security boundary. A broad earlier allow can undermine the intended more restrictive access design. The appropriate controlled recovery is: Reorder or scope the policy rules and verify accepted and denied traffic.
D:Delete all rule groups to test priority in production. This would not reliably restore the intended security boundary. A broad earlier allow can undermine the intended more restrictive access design. The appropriate controlled recovery is: Reorder or scope the policy rules and verify accepted and denied traffic.
Question 351
A vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server. What is the most defensible Azure security action?
- Open all private subnet ports to the Internet instead of configuring DNAT.
- Assume an outbound application rule automatically publishes an inbound service.
- Use a storage SAS token to translate firewall packet destinations.
- Create an approved DNAT rule with correct original public destination, translated private endpoint and allowed port.
Explanation
Correct Answer
D:Confirm the change against these records: Public IP, DNAT rule mapping, destination reachability and firewall flow log. Azure Firewall destination NAT performs explicit inbound address and port translation.
Incorrect Answers
A:An allow rule without the needed translation does not deliver traffic to the private target. Open all private subnet ports to the Internet instead of configuring DNAT.
B:Assume an outbound application rule automatically publishes an inbound service. The proposed change targets the wrong mechanism or lacks essential validation. Azure Firewall destination NAT performs explicit inbound address and port translation. Relevant evidence is public IP, DNAT rule mapping, destination reachability and firewall flow log.
C:An allow rule without the needed translation does not deliver traffic to the private target. The intended action is: Create an approved DNAT rule with correct original public destination, translated private endpoint and allowed port.
Question 352
A vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server. Which diagnostic record would most strongly confirm the result?
- 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.
- Public IP, DNAT rule mapping, destination reachability and firewall flow log.
Explanation
Correct Answer
D:These records test the actual Azure Firewall DNAT inbound publishing behavior rather than an unrelated dashboard state. Azure Firewall destination NAT performs explicit inbound address and port translation.
Incorrect Answers
A:On its own, that evidence does not prove the specified security control works. The more relevant observations are: Public IP, DNAT rule mapping, destination reachability and firewall flow log.
B:On its own, that evidence does not prove the specified security control works. Azure Firewall destination NAT performs explicit inbound address and port translation.
C:On its own, that evidence does not prove the specified security control works. In the given case, a vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server.
Question 353
A vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server. Which platform concept should guide the engineer’s assessment?
- Azure Firewall destination NAT performs explicit inbound address and port translation.
- 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.
- Successful public name resolution proves that all traffic uses Private Link.
Explanation
Correct Answer
A:This principle supports the security response: Create an approved DNAT rule with correct original public destination, translated private endpoint and allowed port. Confirmation depends on Public IP, DNAT rule mapping, destination reachability and firewall flow log.
Incorrect Answers
B:Creating a virtual network peering link makes all other Azure VNets transitively reachable. This is an incorrect assumption for Azure Firewall DNAT inbound publishing. The relevant security behavior is: Azure Firewall destination NAT performs explicit inbound address and port translation. Check evidence such as public IP, DNAT rule mapping, destination reachability and firewall flow log.
C:An NSG allow is sufficient even when another relevant security layer explicitly denies the flow. This is an incorrect assumption for Azure Firewall DNAT inbound publishing. The relevant security behavior is: Azure Firewall destination NAT performs explicit inbound address and port translation.

Check evidence such as public IP, DNAT rule mapping, destination reachability and firewall flow log.
Question 354
A vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server. Suppose the operator instead follows this unsafe shortcut: Open all private subnet ports to the Internet instead of configuring DNAT. Which root-cause observation follows from that incorrect change?
- An allow rule without the needed translation does not deliver traffic to the private target.
- The investigation itself created the pre-existing private DNS or route mismatch.
- The failure consists only of retaining valid network flow logs.
- A VNet diagram label alone explains the blocked or uninspected traffic.
Explanation
Correct Answer
A:The suitable control is: Create an approved DNAT rule with correct original public destination, translated private endpoint and allowed port. This is a material consequence of the incorrect shortcut.
Incorrect Answers
B:This does not explain the real Azure Firewall DNAT inbound publishing weakness after the shortcut. The material failure is: An allow rule without the needed translation does not deliver traffic to the private target.
C:This does not explain the real Azure Firewall DNAT inbound publishing weakness after the shortcut. Inspect evidence such as public IP, DNAT rule mapping, destination reachability and firewall flow log.
D:This does not explain the real Azure Firewall DNAT inbound publishing weakness after the shortcut. In the given case, a vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server.
Question 355
A vendor application must accept inbound traffic through Azure Firewall but a network rule alone does not forward the public address to its private server. A review identifies this consequence: An allow rule without the needed translation does not deliver traffic to the private target. Which recovery action addresses the underlying technical fault?
- Assume an outbound application rule automatically publishes an inbound service.
- Correct the DNAT mapping and validate only the intended published service.
- Use a storage SAS token to translate firewall packet destinations.
- Open all private subnet ports to the Internet instead of configuring DNAT.
Explanation
Correct Answer
B:Test using these records: Public IP, DNAT rule mapping, destination reachability and firewall flow log. This addresses the observed security problem while providing a verifiable outcome.
Incorrect Answers
A:That option would assume an outbound application rule automatically publishes an inbound service, but it addresses a different concern. This addresses the observed security problem while providing a verifiable outcome.
C:That option would use a storage SAS token to translate firewall packet destinations, but it addresses a different concern. This addresses the observed security problem while providing a verifiable outcome.
D:Open all private subnet ports to the Internet instead of configuring DNAT. This would not reliably restore the intended security boundary. An allow rule without the needed translation does not deliver traffic to the private target. The appropriate controlled recovery is: Correct the DNAT mapping and validate only the intended published service.
