Question 10
The acceptance test asks: A new host subnet has an NSG that blocks outbound access needed by the AVD service. Which observation MOST DIRECTLY verifies the appropriate corrective approach succeeded?
Explanation
Correct Answer
The test concerns: A new host subnet has an NSG that blocks outbound access needed by the AVD service. Decisive evidence is: Host agents register and client sessions connect while public inbound TCP 3389 remains denied. This confirms the intended correction (Plan session-host subnets, DNS, outbound service connectivity and controlled NSG rules without exposing inbound RDP to the internet.) and tests the failure risk: An isolated subnet with blocked required outbound endpoints can stop agents from registering even when the VMs are running. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.
Incorrect Answers
This option relates to Network connection and DNS troubleshooting under AZ-140 objective group 1.1. It addresses a different failure risk: Changing broad firewall rules without identifying the blocked destination can reduce security and leave the real connectivity issue unresolved. But the observed requirement is: A new host subnet has an NSG that blocks outbound access needed by the AVD service. For the targeted topic (Session-host subnet and egress design), the directly relevant verification is: Host agents register and client sessions connect while public inbound TCP 3389 remains denied. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Network throughput and session latency planning under AZ-140 objective group 1.1. It addresses a different failure risk: Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions. But the observed requirement is: A new host subnet has an NSG that blocks outbound access needed by the AVD service. For the targeted topic (Session-host subnet and egress design), the directly relevant verification is: Host agents register and client sessions connect while public inbound TCP 3389 remains denied. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
This option relates to Azure Private Link for AVD control-plane access under AZ-140 objective group 1.1. It addresses a different failure risk: Creating a private endpoint without matching DNS and route configuration can make clients resolve an unreachable public or private address. But the observed requirement is: A new host subnet has an NSG that blocks outbound access needed by the AVD service. For the targeted topic (Session-host subnet and egress design), the directly relevant verification is: Host agents register and client sessions connect while public inbound TCP 3389 remains denied. That other measure may be useful in a separate environment, but does not by itself establish the specific requested outcome. An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.
