Question 230

A desktop service validation exercise records: An administrator installs applications into an image but forgets required reboot before capture. Which observation MOST DIRECTLY verifies the appropriate corrective approach succeeded?

  1. New hosts in each approved region can select the intended image version without manual file copying.
  2. Canary hosts meet approved sign-in and app-health gates before a phased fleet rollout, and rollback remains available.
  3. Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests.
  4. A test VM from the chosen custom image boots and can register in its intended host pool.

Explanation

Correct Answer

C:

The test concerns: An administrator installs applications into an image but forgets required reboot before capture. Decisive evidence is: Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests. This confirms the intended correction (Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version.) and tests the failure risk: Publishing patches directly to all production image-based hosts without validation may introduce sign-in or app incompatibility. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.

Incorrect Answers

A:

This option relates to Azure Compute Gallery image distribution under AZ-140 objective group 1.5. It addresses a different failure risk: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. But the observed requirement is: An administrator installs applications into an image but forgets required reboot before capture. For the targeted topic (OS updates and application compatibility in images), the directly relevant verification is: Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests. 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 Image rollout canary and rollback strategy under AZ-140 objective group 1.5. It addresses a different failure risk: Replacing every production host with an untested image can spread authentication, app or agent failures simultaneously. But the observed requirement is: An administrator installs applications into an image but forgets required reboot before capture. For the targeted topic (OS updates and application compatibility in images), the directly relevant verification is: Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests. 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 Custom image VM generation and compatibility under AZ-140 objective group 1.5. It addresses a different failure risk: A V2 image deployed on an incompatible VM generation or unsupported OS may fail provisioning even when gallery permissions are correct. But the observed requirement is: An administrator installs applications into an image but forgets required reboot before capture. For the targeted topic (OS updates and application compatibility in images), the directly relevant verification is: Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests. 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 231

An Azure session host operator observes: A pilot seeks evidence that the patched image does not degrade user sign-in time. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version.
  2. Validate custom image architecture, generation, OS eligibility and compatible VM size before deploying session hosts.
  3. Publish versioned images through Azure Compute Gallery with suitable regional replication and access permissions for deployment locations.
  4. Use Azure VM Image Builder with a reviewed build template and customizers to produce validated session-host images from approved sources.

Explanation

Correct Answer

A:

The AVD operational observation is: A pilot seeks evidence that the patched image does not degrade user sign-in time. The most targeted response is: Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version. This addresses the specific failure mechanism: Publishing patches directly to all production image-based hosts without validation may introduce sign-in or app incompatibility. Verify the outcome by checking: Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests. The chosen response directly resolves the stated requirement, rather than changing another Azure Virtual Desktop configuration area.

D:

This option relates to Azure VM Image Builder repeatable image creation under AZ-140 objective group 1.5. It addresses a different failure risk: Manually updating a single golden VM offers poor auditability and inconsistent package versions across image releases. But the observed requirement is: A pilot seeks evidence that the patched image does not degrade user sign-in time. For the targeted topic (OS updates and application compatibility in images), the directly relevant action is: Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version. 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 232

The AVD reviewer evaluates: A pilot seeks evidence that the patched image does not degrade user sign-in time. Select TWO complementary choices: the recommended response AND the evidence that confirms it worked.

  1. Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version.
  2. Canary hosts meet approved sign-in and app-health gates before a phased fleet rollout, and rollback remains available.
  3. A V2 image deployed on an incompatible VM generation or unsupported OS may fail provisioning even when gallery permissions are correct.
  4. Use Azure VM Image Builder with a reviewed build template and customizers to produce validated session-host images from approved sources.
  5. Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests.

Question 233

An AVD infrastructure administrator reports: A release team wants to freeze its host pool on a validated image during a busy season. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Publish versioned images through Azure Compute Gallery with suitable regional replication and access permissions for deployment locations.
  2. Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period.
  3. Replace a limited set of drained session hosts with a new approved image, validate the canary and expand only after observed health checks.
  4. Apply approved Windows and application updates to a staging image, test AVD agent and enterprise applications, then promote the version.

Explanation

Correct Answer

B:

The AVD operational observation is: A release team wants to freeze its host pool on a validated image during a busy season. The most targeted response is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. This addresses the specific failure mechanism: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. Verify the outcome by checking: Deployment records show the approved image version and a previous tested version remains available for rollback. 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 Compute Gallery image distribution under AZ-140 objective group 1.5.

Question 234

The acceptance test asks: A release team wants to freeze its host pool on a validated image during a busy season. Which observation MOST DIRECTLY verifies the appropriate corrective approach succeeded?

  1. An Image Builder run records the source, customizations, tests and produced artifact version.
  2. A test VM from the chosen custom image boots and can register in its intended host pool.
  3. Deployment records show the approved image version and a previous tested version remains available for rollback.
  4. A new host built from the image registers cleanly and receives an independent computer identity.

Question 235

A virtual desktop service ticket states: An Azure Compute Gallery version is removed before affected hosts can be rebuilt. Which response BEST addresses the specific AZ-140 operational requirement?

  1. Prepare a supported reference VM, install approved applications, clean temporary state and capture a properly generalized image for repeated session host deployments.
  2. Validate custom image architecture, generation, OS eligibility and compatible VM size before deploying session hosts.
  3. Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period.

Question 236

A post-change operational risk review considers: An Azure Compute Gallery version is removed before affected hosts can be rebuilt. Which risk MOST DIRECTLY explains the need for the proposed AVD control?

  1. A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere.
  2. Replacing every production host with an untested image can spread authentication, app or agent failures simultaneously.
  3. Deploying latest without review can move new session hosts to an untested build and make rollback uncertain.
  4. Publishing patches directly to all production image-based hosts without validation may introduce sign-in or app incompatibility.

Explanation

Correct Answer

C:

The condition is: An Azure Compute Gallery version is removed before affected hosts can be rebuilt. The directly related risk is: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. The corrective control is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. Its test of effectiveness is: Deployment records show the approved image version and a previous tested version remains available for rollback.

The most targeted response is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. This addresses the specific failure mechanism: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. Verify the outcome by checking: Deployment records show the approved image version and a previous tested version remains available for rollback. The chosen response directly resolves the stated requirement, rather than changing another Azure Virtual Desktop configuration area.

Incorrect Answers

A:

This option relates to Manual session host image preparation and generalization under AZ-140 objective group 1.5. It addresses a different failure risk: Cloning a reference VM without preparing a reusable image can carry unintended identities, temporary data or configuration defects. But the observed requirement is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant action is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. 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 Azure Compute Gallery image distribution under AZ-140 objective group 1.5. It addresses a different failure risk: A single-region image artifact may be inaccessible or slow to distribute when large host pools are provisioned elsewhere. But the observed requirement is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant action is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. 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 Custom image VM generation and compatibility under AZ-140 objective group 1.5. It addresses a different failure risk: A V2 image deployed on an incompatible VM generation or unsupported OS may fail provisioning even when gallery permissions are correct. But the observed requirement is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant action is: Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period. 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 240

The AVD reviewer evaluates: An image lifecycle policy needs explicit retention and deprecation dates for old versions. Select TWO complementary choices: the recommended response AND the evidence that confirms it worked.

  1. Staging hosts built from the new image pass functional logon, FSLogix, app-launch and patch verification tests.
  2. Deployment records show the approved image version and a previous tested version remains available for rollback.
  3. Replacing every production host with an untested image can spread authentication, app or agent failures simultaneously.
  4. Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period.
  5. Validate custom image architecture, generation, OS eligibility and compatible VM size before deploying session hosts.

Explanation

Correct Answers

B:

The test concerns: An image lifecycle policy needs explicit retention and deprecation dates for old versions. Decisive evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. This confirms the intended correction (Maintain clearly named image versions and retirement stages, pin deployments to approved versions and retain rollback candidates for a defined period.) and tests the failure risk: Deploying latest without review can move new session hosts to an untested build and make rollback uncertain. Other healthy Azure resources or unrelated service telemetry would not, by themselves, establish success for this case.

Incorrect Answers

A:

This option relates to OS updates and application compatibility in images under AZ-140 objective group 1.5. It addresses a different failure risk: Publishing patches directly to all production image-based hosts without validation may introduce sign-in or app incompatibility. But the observed requirement is: An image lifecycle policy needs explicit retention and deprecation dates for old versions. For the targeted topic (Image version pinning and lifecycle retention), the directly relevant paired response and evidence is: Deployment records show the approved image version and a previous tested version remains available for rollback. 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.
