Microsoft AZ-140 Practice Test 1

Question 1

An AVD infrastructure administrator reports: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Configure supported Azure Virtual Desktop private endpoints, required private DNS resolution and associated network access for the intended AVD service resources.
  2. Trace client, host, DNS, proxy, firewall, endpoint and Azure network diagnostics to isolate the failing segment before relaxing controls.
  3. Plan session-host subnets, DNS, outbound service connectivity and controlled NSG rules without exposing inbound RDP to the internet.
  4. Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement.

Explanation

Correct Answer

D:

The AVD operational observation is: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. The most targeted response is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. This addresses the specific failure mechanism: Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions. Verify the outcome by checking: Pilot users in each location meet documented RTT, bandwidth and session responsiveness targets. The chosen response directly resolves the stated requirement, rather than changing another Azure Virtual Desktop configuration area.

Incorrect Answers

A:

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: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. For the targeted topic (Network throughput and session latency planning), the directly relevant action is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. 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.

B:

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: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. For the targeted topic (Network throughput and session latency planning), the directly relevant action is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. 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.

C:

This option relates to Session-host subnet and egress design under AZ-140 objective group 1.1. It addresses a different failure risk: An isolated subnet with blocked required outbound endpoints can stop agents from registering even when the VMs are running. But the observed requirement is: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. For the targeted topic (Network throughput and session latency planning), the directly relevant action is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. 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.

Question 2

The acceptance test asks: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. Which observation MOST DIRECTLY verifies the appropriate corrective approach succeeded?

  1. A reproducible sign-in failure maps to a specific blocked destination or DNS error and succeeds after a scoped fix.
  2. Diagnostics and a controlled network impairment test show the intended path behavior and session quality.
  3. Pilot users in each location meet documented RTT, bandwidth and session responsiveness targets.
  4. DNS inspection and connection tests show AVD traffic following approved private endpoint paths where supported.

Explanation

Correct Answer

C:

The test concerns: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. Decisive evidence is: Pilot users in each location meet documented RTT, bandwidth and session responsiveness targets. This confirms the intended correction (Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement.) and tests the failure risk: Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.

B:

This option relates to RDP Multipath and QoS policy selection under AZ-140 objective group 1.1. It addresses a different failure risk: A transport policy applied without checking client support and network treatment may create no measurable benefit. But the observed requirement is: An enterprise adds 900 remote users from three distant offices and needs a network readiness decision. For the targeted topic (Network throughput and session latency planning), the directly relevant verification is: Pilot users in each location meet documented RTT, bandwidth and session responsiveness targets.

Question 3

A virtual desktop service ticket states: An AVD pilot has good VM CPU but slow screen updates from a remote branch. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Configure supported Azure Virtual Desktop private endpoints, required private DNS resolution and associated network access for the intended AVD service resources.
  2. Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement.
  3. Trace client, host, DNS, proxy, firewall, endpoint and Azure network diagnostics to isolate the failing segment before relaxing controls.
  4. Enable and validate an appropriate RDP Shortpath path with supported UDP connectivity and firewall rules while retaining standard transport fallback.

Explanation

Correct Answer

B:

The AVD operational observation is: An AVD pilot has good VM CPU but slow screen updates from a remote branch. The most targeted response is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. This addresses the specific failure mechanism: Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions.

An independent qualified Azure Virtual Desktop expert must adjudicate any plausible overlapping alternatives before release.

D:

This option relates to RDP Shortpath direct UDP transport under AZ-140 objective group 1.1. It addresses a different failure risk: Blocking UDP can force sessions to use fallback transport and worsen interactive latency for suitable network paths. But the observed requirement is: An AVD pilot has good VM CPU but slow screen updates from a remote branch. For the targeted topic (Network throughput and session latency planning), the directly relevant action is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. 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.

Question 4

A post-change operational risk review considers: An AVD pilot has good VM CPU but slow screen updates from a remote branch. Which risk MOST DIRECTLY explains the need for the proposed AVD control?

  1. An isolated subnet with blocked required outbound endpoints can stop agents from registering even when the VMs are running.
  2. A transport policy applied without checking client support and network treatment may create no measurable benefit.
  3. Creating a private endpoint without matching DNS and route configuration can make clients resolve an unreachable public or private address.
  4. Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions.

Explanation

Correct Answer

D:

The condition is: An AVD pilot has good VM CPU but slow screen updates from a remote branch. The directly related risk is: Sizing solely from VM CPU ignores client latency and bandwidth constraints that directly degrade interactive sessions. The corrective control is: Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement. Its test of effectiveness is: Pilot users in each location meet documented RTT, bandwidth and session responsiveness targets. This issue is specific to the observed AVD behavior, not to a separate administration concern.

Question 5

An AVD design review identifies: A design team must estimate simultaneous video calls over a constrained corporate link. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Enable and validate an appropriate RDP Shortpath path with supported UDP connectivity and firewall rules while retaining standard transport fallback.
  2. Assess supported RDP Multipath and quality-of-service policies across variable networks, validate transport choices, and avoid assuming all clients support every feature.
  3. Measure expected concurrent users, workload bandwidth, RTT and network paths before sizing AVD connectivity and regional placement.
  4. Configure supported Azure Virtual Desktop private endpoints, required private DNS resolution and associated network access for the intended AVD service resources.

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

A:

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.

B:

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.

D:

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.
