Question 760

A production app update must avoid user-visible disruption and support quick rollback. Which Azure architecture choice best meets this requirement?

  1. Replace every instance immediately without retaining an old release.
  2. Ignore drift because the last pipeline run was successful.
  3. Use blue-green or canary deployment with health checks and traffic rollback.
  4. Create production resources manually from unrecorded portal clicks.

Explanation

Correct Answer

C:

Progressive release limits error exposure while retaining a known-good version.

Incorrect Answers

A:

Full cutover increases outage blast radius. This proposal contradicts the stated architecture constraint.

B:

Subsequent manual edits can invalidate previously approved configuration. In the present requirement, a production app update must avoid user-visible disruption and support quick rollback. The needed design instead works because progressive release limits error exposure while retaining a known-good version.

D:

Manual configuration complicates drift detection and rollback. In the present requirement, a production app update must avoid user-visible disruption and support quick rollback. The needed design instead works because progressive release limits error exposure while retaining a known-good version.

Question 761

An architecture proposal for application ci/cd and iac releases relies on the following approach: Replace every instance immediately without retaining an old release. Which specific failure or mismatch should the design reviewer identify?

  1. Full cutover increases outage blast radius.
  2. Manual configuration complicates drift detection and rollback.
  3. Cache loss would destroy authoritative business data.
  4. Subsequent manual edits can invalidate previously approved configuration.

Explanation

Correct Answer

A:

Replace every instance immediately without retaining an old release. Full cutover increases outage blast radius.

Incorrect Answers

B:

That assessment refers to the separate proposal 'Create production resources manually from unrecorded portal clicks.' not to the recommendation under review. Here, Full cutover increases outage blast radius.

C:

This concern applies to Store the only copy of accepted orders in volatile cache memory. in another design an application architecture design. The current proposal specifically fails because full cutover increases outage blast radius.

D:

That assessment refers to the separate proposal 'Ignore drift because the last pipeline run was successful.' not to the recommendation under review. Here, Full cutover increases outage blast radius.

Question 762

Acceptance testing must establish the following operational result: Canary metrics and rollback time prove release safety. Which verification action most directly establishes that outcome?

  1. Run a non-mutating plan and review proposed changes.
  2. Route a small test share to the new build and trigger a rollback.
  3. Restart the cache during a test transaction and check durable order integrity.
  4. Compare plan outputs for test and production with version-controlled sources.

Explanation

Correct Answer

B:

Canary metrics and rollback time prove release safety.

Incorrect Answers

A:

That verification addresses the different requirement: A team has drift between the approved IaC definition and a running resource. It does not directly establish canary metrics and rollback time prove release safety.

C:

This is a test for A caching tier fails and the app must still serve its critical order workflow. The requirement here is instead demonstrated by route a small test share to the new build and trigger a rollback.

D:

That verification addresses the different requirement: A team deploys the same Azure app stack to test and production with environment-specific variables. It does not directly establish canary metrics and rollback time prove release safety.

Question 763

A team has drift between the approved IaC definition and a running resource. Which Azure architecture choice best meets this requirement?

  1. Detect and reconcile configuration drift through planned state comparison.
  2. Replace every instance immediately without retaining an old release.
  3. Ignore drift because the last pipeline run was successful.
  4. Create production resources manually from unrecorded portal clicks.

Explanation

Correct Answer

A:

IaC change review is effective only when deployed resources match declared intent.

Incorrect Answers

B:

Full cutover increases outage blast radius. In the present requirement, a team has drift between the approved IaC definition and a running resource. The needed design instead works because iaC change review is effective only when deployed resources match declared intent.

C:

Subsequent manual edits can invalidate previously approved configuration. This proposal contradicts the stated architecture constraint.

D:

Manual configuration complicates drift detection and rollback. In the present requirement, a team has drift between the approved IaC definition and a running resource. The needed design instead works because iaC change review is effective only when deployed resources match declared intent.

Question 764

An architecture proposal for application ci/cd and iac releases relies on the following approach: Ignore drift because the last pipeline run was successful. Which specific failure or mismatch should the design reviewer identify?

  1. Manual configuration complicates drift detection and rollback.
  2. Subsequent manual edits can invalidate previously approved configuration.
  3. Full cutover increases outage blast radius.
  4. Queue competing receivers split messages rather than broadcasting.

Explanation

Correct Answer

B:

Ignore drift because the last pipeline run was successful. Subsequent manual edits can invalidate previously approved configuration.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Create production resources manually from unrecorded portal clicks.' not to the recommendation under review. Here, Subsequent manual edits can invalidate previously approved configuration.

C:

That assessment refers to the separate proposal 'Replace every instance immediately without retaining an old release.' not to the recommendation under review. Here, Subsequent manual edits can invalidate previously approved configuration.

D:

This concern applies to Put all processors on one competing queue and expect each receives every message. in another design an application architecture design. The current proposal specifically fails because subsequent manual edits can invalidate previously approved configuration.

Question 765

Acceptance testing must establish the following operational result: The diff identifies unauthorized drift before remediation. Which verification action most directly establishes that outcome?

  1. Run a non-mutating plan and review proposed changes.
  2. Route a small test share to the new build and trigger a rollback.
  3. Compare plan outputs for test and production with version-controlled sources.
  4. Publish one event and inspect every subscription's copy.

Explanation

Correct Answer

A:

The diff identifies unauthorized drift before remediation.

Incorrect Answers

B:

That verification addresses the different requirement: A production app update must avoid user-visible disruption and support quick rollback. It does not directly establish the diff identifies unauthorized drift before remediation.

C:

That verification addresses the different requirement: A team deploys the same Azure app stack to test and production with environment-specific variables. It does not directly establish the diff identifies unauthorized drift before remediation.

D:

This is a test for A service must broadcast each business event to several independently subscribed line-of-business processors. The requirement here is instead demonstrated by run a non-mutating plan and review proposed changes.

Question 766

An enterprise wants to right-size an on-premises VM migration and avoid breaking application dependencies. Which TWO assessments should precede cutover? (Select TWO.)

  1. Migrate servers in alphabetical order without dependency assessment.
  2. Delete source servers before test migration validation.
  3. Pick every target as the smallest VM without an observation period.
  4. Map application and database dependencies to form safe migration waves.
  5. Collect representative CPU, memory and disk utilization using Azure Migrate assessment.

Explanation

Correct Answers

D:

Traffic dependencies influence cutover sequencing.

E:

Performance-based sizing reduces over- and under-provisioning.

Incorrect Answers

A:

Ordering by hostname ignores service relationships.

B:

Premature deletion eliminates rollback options.

C:

An unmeasured peak may exceed target capacity.

Question 767

An architecture proposal for azure migrate discovery and sizing relies on the following approach: Estimate every workload as the same VM size using only server count. Which specific failure or mismatch should the design reviewer identify?

  1. Size-only extrapolation ignores utilization and dependencies.
  2. A short idle window misses critical workload spikes.
  3. Unencrypted removable media can expose regulated content.
  4. Unplanned sequence can strand database-dependent applications.

Explanation

Correct Answer

A:

Estimate every workload as the same VM size using only server count. Size-only extrapolation ignores utilization and dependencies.

Incorrect Answers

B:

That assessment refers to the separate proposal 'Size the target from the previous hour of minimal utilization only.' not to the recommendation under review. Here, Size-only extrapolation ignores utilization and dependencies.

C:

This concern applies to Copy plaintext data to an unmanaged USB drive and ship without control. in another design migrations design. The current proposal specifically fails because size-only extrapolation ignores utilization and dependencies.

D:

That assessment refers to the separate proposal 'Move servers in arbitrary alphabetical order without testing interdependencies.' not to the recommendation under review. Here, Size-only extrapolation ignores utilization and dependencies.

Question 768

Acceptance testing must establish the following operational result: Discovery evidence supports target sizing. Which verification action most directly establishes that outcome?

  1. Verify upload status, transfer logs and secure wipe procedures.
  2. Compare discovered CPU, memory and disks for representative workloads.
  3. Review peak distribution and confidence across the assessment period.
  4. Validate the proposed migration wave's dependency graph.

Explanation

Correct Answer

B:

Discovery evidence supports target sizing.

Incorrect Answers

A:

This is a test for The organization ships a Data Box appliance containing sensitive data. The requirement here is instead demonstrated by compare discovered CPU, memory and disks for representative workloads.

C:

That verification addresses the different requirement: A workload appears idle most of the day but has intense month-end reporting. It does not directly establish discovery evidence supports target sizing.

D:

That verification addresses the different requirement: Migration sequencing is blocked by unknown communication dependencies between app and database tiers. It does not directly establish discovery evidence supports target sizing.

Question 769

A workload appears idle most of the day but has intense month-end reporting. Which Azure architecture choice best meets this requirement?

  1. Estimate every workload as the same VM size using only server count.
  2. Use performance-based Azure Migrate assessment with an appropriate observation window.
  3. Move servers in arbitrary alphabetical order without testing interdependencies.
  4. Size the target from the previous hour of minimal utilization only.

Explanation

Correct Answer

B:

Representative historical samples prevent undersizing periodic peaks.

Incorrect Answers

A:

Size-only extrapolation ignores utilization and dependencies. In the present requirement, a workload appears idle most of the day but has intense month-end reporting. The needed design instead works because representative historical samples prevent undersizing periodic peaks.

C:

Unplanned sequence can strand database-dependent applications. In the present requirement, a workload appears idle most of the day but has intense month-end reporting. The needed design instead works because representative historical samples prevent undersizing periodic peaks.

D:

A short idle window misses critical workload spikes. This proposal contradicts the stated architecture constraint.

  4. Size-only extrapolation ignores utilization and dependencies.

Explanation

Correct Answer

B:

Size the target from the previous hour of minimal utilization only. A short idle window misses critical workload spikes.

Incorrect Answers

A:

This concern applies to Assume the appliance automatically repairs every application connection string. in another design migrations design. The current proposal specifically fails because a short idle window misses critical workload spikes.

C:

That assessment refers to the separate proposal 'Move servers in arbitrary alphabetical order without testing interdependencies.' not to the recommendation under review. Here, A short idle window misses critical workload spikes.
