Question 860
An architecture proposal for azure virtual wan routing relies on the following approach: Propagate all sensitive prefixes to every connection by default. Which specific failure or mismatch should the design reviewer identify?
- NSGs without proper restrictions do not provide centralized controlled egress.
- An NSG does not replace centrally routed network firewall inspection.
- Broad propagation defeats separation requirements.
- Ad hoc mesh operations become difficult at global scale.
Explanation
Correct Answer
C:Propagate all sensitive prefixes to every connection by default. Broad propagation defeats separation requirements.
Incorrect Answers
A:This concern applies to Configure only default NSG allow-all rules on every subnet. in another design network solutions design. The current proposal specifically fails because broad propagation defeats separation requirements.
B:That assessment refers to the separate proposal 'Assume a regular VNet NSG is a stateful central transit firewall for all hubs.' not to the recommendation under review. Here, Broad propagation defeats separation requirements.
D:That assessment refers to the separate proposal 'Build hundreds of independent point-to-point tunnels with no routing framework.' not to the recommendation under review. Here, Broad propagation defeats separation requirements.
Question 861
Acceptance testing must establish the following operational result: Differential routes validate segmentation. Which verification action most directly establishes that outcome?
- Test reachability from restricted and permitted connections.
- Inspect propagated branch and VNet routes through representative hubs.
- Test an allowed destination and a denied domain or IP from a spoke.
- Trace a protected flow and confirm firewall log entries.
Explanation
Correct Answer
A:Differential routes validate segmentation.
Incorrect Answers
B:That verification addresses the different requirement: An enterprise connects dozens of global branches and VNets with central routing governance. It does not directly establish differential routes validate segmentation.
C:This is a test for A hub must inspect outbound traffic from many spokes and restrict destinations by policy. The requirement here is instead demonstrated by test reachability from restricted and permitted connections.
D:That verification addresses the different requirement: A deployment needs centrally inserted inspection for cross-branch traffic in a managed network fabric. It does not directly establish differential routes validate segmentation.
Question 862
A deployment needs centrally inserted inspection for cross-branch traffic in a managed network fabric. Which Azure architecture choice best meets this requirement?
- Build hundreds of independent point-to-point tunnels with no routing framework.
- Propagate all sensitive prefixes to every connection by default.
- Assume a regular VNet NSG is a stateful central transit firewall for all hubs.
- Evaluate a secured Virtual WAN hub with supported Azure Firewall routing intent.
Explanation
Correct Answer
D:Managed hubs can direct eligible traffic through inspected paths.
Incorrect Answers
A:Ad hoc mesh operations become difficult at global scale. In the present requirement, a deployment needs centrally inserted inspection for cross-branch traffic in a managed network fabric. The needed design instead works because managed hubs can direct eligible traffic through inspected paths.
B:Broad propagation defeats separation requirements. In the present requirement, a deployment needs centrally inserted inspection for cross-branch traffic in a managed network fabric. The needed design instead works because managed hubs can direct eligible traffic through inspected paths.
C:An NSG does not replace centrally routed network firewall inspection. This proposal contradicts the stated architecture constraint.

Explanation
Correct Answer
A:Assume a regular VNet NSG is a stateful central transit firewall for all hubs. An NSG does not replace centrally routed network firewall inspection.
Incorrect Answers
B:That assessment refers to the separate proposal 'Build hundreds of independent point-to-point tunnels with no routing framework.' not to the recommendation under review. Here, An NSG does not replace centrally routed network firewall inspection.
C:This concern applies to Build a site-to-site tunnel from every individual laptop as a branch router. in another design network solutions design. The current proposal specifically fails because an NSG does not replace centrally routed network firewall inspection.
D:That assessment refers to the separate proposal 'Propagate all sensitive prefixes to every connection by default.' not to the recommendation under review. Here, An NSG does not replace centrally routed network firewall inspection.
Question 864
Acceptance testing must establish the following operational result: The observed path demonstrates traffic inspection. Which verification action most directly establishes that outcome?
- Test reachability from restricted and permitted connections.
- Inspect propagated branch and VNet routes through representative hubs.
- Test a client authentication and a permitted private address route.
- Trace a protected flow and confirm firewall log entries.
Explanation
Correct Answer
D:The observed path demonstrates traffic inspection.
Incorrect Answers
A:That verification addresses the different requirement: Two Virtual WAN route tables must isolate sensitive workloads while retaining shared services. It does not directly establish the observed path demonstrates traffic inspection.
B:That verification addresses the different requirement: An enterprise connects dozens of global branches and VNets with central routing governance. It does not directly establish the observed path demonstrates traffic inspection.
C:This is a test for Remote employees need individually authenticated access to private Azure networks. The requirement here is instead demonstrated by trace a protected flow and confirm firewall log entries.
Question 865
A hub must inspect outbound traffic from many spokes and restrict destinations by policy. Which Azure architecture choice best meets this requirement?
- Configure only default NSG allow-all rules on every subnet.
- Change only the NSG rule and assume it rewrites the route table.
- Use Azure Firewall with suitable UDR or routing architecture and network rules.
- Grant the source VM Owner rights to bypass an IP firewall denial.
Explanation
Correct Answer
C:Central stateful policy supports shared egress governance.
Incorrect Answers
A:NSGs without proper restrictions do not provide centralized controlled egress. This proposal contradicts the stated architecture constraint.
B:NSGs filter traffic but do not choose the next hop. In the present requirement, a hub must inspect outbound traffic from many spokes and restrict destinations by policy. The needed design instead works because central stateful policy supports shared egress governance.
D:RBAC management privilege does not replace network firewall rules. In the present requirement, a hub must inspect outbound traffic from many spokes and restrict destinations by policy. The needed design instead works because central stateful policy supports shared egress governance.
Question 866
An architecture proposal for azure firewall and routing control relies on the following approach: Configure only default NSG allow-all rules on every subnet. Which specific failure or mismatch should the design reviewer identify?
- NSGs filter traffic but do not choose the next hop.
- NSGs without proper restrictions do not provide centralized controlled egress.
- ExpressRoute requires a supported private circuit and separate provisioning.
- RBAC management privilege does not replace network firewall rules.
Explanation
Correct Answer
B:Configure only default NSG allow-all rules on every subnet. NSGs without proper restrictions do not provide centralized controlled egress.
Incorrect Answers
A:That assessment refers to the separate proposal 'Change only the NSG rule and assume it rewrites the route table.' not to the recommendation under review. Here, NSGs without proper restrictions do not provide centralized controlled egress.
C:This concern applies to Configure ExpressRoute without any carrier circuit and call it an internet VPN. in another design network solutions design. The current proposal specifically fails because nSGs without proper restrictions do not provide centralized controlled egress.
D:That assessment refers to the separate proposal 'Grant the source VM Owner rights to bypass an IP firewall denial.' not to the recommendation under review. Here, NSGs without proper restrictions do not provide centralized controlled egress.
Question 867
Acceptance testing must establish the following operational result: Traffic and firewall logs validate enforced policy. Which verification action most directly establishes that outcome?
- Test an allowed destination and a denied domain or IP from a spoke.
- Correlate source/destination packet test with the firewall's rule hit.
- Establish the tunnel and test protected private IP reachability.
- Inspect effective routes and observe flow through the appliance.
Explanation
Correct Answer
A:Traffic and firewall logs validate enforced policy.
Incorrect Answers
B:That verification addresses the different requirement: An internal firewall rule logs denied traffic that network operators cannot explain. It does not directly establish traffic and firewall logs validate enforced policy.
C:This is a test for A branch must connect to one Azure VNet over the public internet with encryption. The requirement here is instead demonstrated by test an allowed destination and a denied domain or IP from a spoke.
D:That verification addresses the different requirement: Sensitive production traffic must traverse an NVA, but packets currently take a direct system route. It does not directly establish traffic and firewall logs validate enforced policy.
Question 868

Explanation
Correct Answer
C:UDRs can steer matching traffic to a virtual appliance.
Incorrect Answers
A:NSGs filter traffic but do not choose the next hop. This proposal contradicts the stated architecture constraint.
B:NSGs without proper restrictions do not provide centralized controlled egress. In the present requirement, sensitive production traffic must traverse an NVA, but packets currently take a direct system route. The needed design instead works because uDRs can steer matching traffic to a virtual appliance.
D:RBAC management privilege does not replace network firewall rules. In the present requirement, sensitive production traffic must traverse an NVA, but packets currently take a direct system route. The needed design instead works because uDRs can steer matching traffic to a virtual appliance.
