Microsoft AZ-305 Practice Test 58

Question 570

The planned architecture is: Create an eligible managed disk snapshot and verify its supported incremental or point-in-time semantics. Workload context: A VM operator wants a quick consistent-time copy of an Azure managed disk before a risky operating system patch. Which acceptance test demonstrates that the required behavior works?

  1. Create a new disk from the snapshot and boot a disposable test VM with the expected data.
  2. Restore all tiers to a tested coordinated recovery scenario and validate business transactions.
  3. Restore a backup point and validate application transaction state rather than only VM boot.
  4. Restore a test folder version from a historical recovery point to a nonproduction share.

Explanation

Correct Answer

A:

The acceptance test is specific: Create a new disk from the snapshot and boot a disposable test VM with the expected data. Its purpose is to establish that the proposed architecture works: Create an eligible managed disk snapshot and verify its supported incremental or point-in-time semantics.

Incorrect Answers

B:

The alternative test targets: Define application-aware recovery orchestration and compatible backup/replication checkpoints across dependent tiers. The scenario's actual proposed remedy is: Create an eligible managed disk snapshot and verify its supported incremental or point-in-time semantics. Verify that one by: Create a new disk from the snapshot and boot a disposable test VM with the expected data.

C:

This check validates a different workload: Restore a backup point and validate application transaction state rather than only VM boot. Its associated design is: Use Azure Backup with an appropriate supported application-consistent backup mechanism for the guest workload. The required acceptance test here is: Create a new disk from the snapshot and boot a disposable test VM with the expected data.

D:

That observation pertains to a separate failure: Deleting a folder removes the only copy of its files immediately. Its cause is: No Azure Files share snapshot/backup recovery policy was applied. It does not confirm the result of this design. The direct proof would be: Create a new disk from the snapshot and boot a disposable test VM with the expected data.

Question 571

The customer states: A VM operator wants a quick consistent-time copy of an Azure managed disk before a risky operating system patch. An incident reveals: A failed patch cannot be undone because there is no independent disk recovery point. What cause best accounts for this evidence?

  1. The backup strategy ignored application-level consistency prerequisites.
  2. Recovery plans were created per resource without application-level consistency and dependency order.
  3. No premaintenance disk snapshot or supported backup point was taken.
  4. No Azure Files share snapshot/backup recovery policy was applied.

Explanation

Correct Answer

C:

The incident is explained by: No premaintenance disk snapshot or supported backup point was taken. The reported symptom is: A failed patch cannot be undone because there is no independent disk recovery point. The corresponding design fix is: Create an eligible managed disk snapshot and verify its supported incremental or point-in-time semantics.

Incorrect Answers

A:

The proposed diagnosis fits another scenario: The backup strategy ignored application-level consistency prerequisites. It would typically be reflected by: A recovered SQL-backed workload has corrupted transaction state after crash-only snapshots. The current evidence instead supports: No premaintenance disk snapshot or supported backup point was taken.

B:

The alternative weakness is: Recovery plans were created per resource without application-level consistency and dependency order. Its associated failure is: VM recovery succeeds but dependent databases reflect inconsistent transaction timestamps. Neither explains the present observation: A failed patch cannot be undone because there is no independent disk recovery point. The direct cause here is: No premaintenance disk snapshot or supported backup point was taken.

D:

The proposed diagnosis fits another scenario: No Azure Files share snapshot/backup recovery policy was applied. It would typically be reflected by: Deleting a folder removes the only copy of its files immediately. The current evidence instead supports: No premaintenance disk snapshot or supported backup point was taken.

Question 572

Workload context: A VM operator wants a quick consistent-time copy of an Azure managed disk before a risky operating system patch. The implemented remedy is: Create an eligible managed disk snapshot and verify its supported incremental or point-in-time semantics. Which ongoing practice most specifically prevents recurrence of this failure: A failed patch cannot be undone because there is no independent disk recovery point.?

  1. Audit file-share backup health and retention after storage account migrations.
  2. Document snapshot lifecycle and avoid treating snapshots alone as full regional DR.
  3. Run integrated restore drills covering identity, DNS and data consistency across tiers.
  4. Rehearse recoveries including database consistency checks after guest-agent upgrades.

Explanation

Correct Answer

B:

The key follow-up control is: Document snapshot lifecycle and avoid treating snapshots alone as full regional DR. It avoids recurrence of the scenario in which: A failed patch cannot be undone because there is no independent disk recovery point. It addresses: No premaintenance disk snapshot or supported backup point was taken.

Incorrect Answers

A:

This is a reasonable safeguard for a different fault: Deleting a folder removes the only copy of its files immediately. That different mechanism is: No Azure Files share snapshot/backup recovery policy was applied. The original incident here instead arises from: No premaintenance disk snapshot or supported backup point was taken. The directly relevant safeguard is: Document snapshot lifecycle and avoid treating snapshots alone as full regional DR.

C:

That safeguard manages another risk: Recovery plans were created per resource without application-level consistency and dependency order. Its scenario is: VM recovery succeeds but dependent databases reflect inconsistent transaction timestamps. The present recurring risk is: No premaintenance disk snapshot or supported backup point was taken. The proper ongoing control is: Document snapshot lifecycle and avoid treating snapshots alone as full regional DR.

D:

This is a reasonable safeguard for a different fault: A recovered SQL-backed workload has corrupted transaction state after crash-only snapshots. That different mechanism is: The backup strategy ignored application-level consistency prerequisites. The original incident here instead arises from: No premaintenance disk snapshot or supported backup point was taken. The directly relevant safeguard is: Document snapshot lifecycle and avoid treating snapshots alone as full regional DR.

Question 573

A solution architect is reviewing a workload: A banking SQL database should recover from an entire regional outage with consistent client routing and an understood asynchronous replication-loss window. The observed incident is: Applications remain pinned to a lost primary server endpoint after SQL recovery. Which architecture choice most directly removes the identified weakness?

  1. Use the declared RPO and RTO to select a realistic continuous replication, backup or multi-region architecture.
  2. Add appropriate cross-region replication and failover design in addition to zone-level high availability.
  3. Design Azure Site Recovery replication for supported VMs, target networking and a tested recovery plan.
  4. Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior.

Explanation

Correct Answer

D:

The targeted implementation is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. The problem is not generic resource availability: The database regional failover and application endpoint strategy were not designed together. Verify the result by: Initiate regional failover in staging and compare latest replicated transactions with primary commit history.

Incorrect Answers

A:

The option belongs to a different failure mechanism: Recovery-point frequency was not assessed against the business RPO. That situation exhibits: An annual backup is approved despite a fifteen-minute maximum data-loss requirement. For the stated case, the remedy is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior.

B:

That design instead addresses another observed condition: All zonally redundant resources become unavailable when the full Azure region fails. Its technical cause is: Availability zones are failure domains inside one region rather than independent geographic sites. The current workload exhibits: Applications remain pinned to a lost primary server endpoint after SQL recovery. Its targeted remedy is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior.

C:

This choice mitigates an alternative scenario, where: After a regional outage, engineers have only VM snapshots in the unavailable primary region. The underlying issue there is: Regional DR replication and orchestrated recovery were not configured for the workloads. Here the root issue is: The database regional failover and application endpoint strategy were not designed together. Choose the corresponding action: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior.

Question 574

An architect proposes this change: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. The workload context is: A banking SQL database should recover from an entire regional outage with consistent client routing and an understood asynchronous replication-loss window. Which evidence would most directly validate the change?

  1. Execute an isolated test failover and confirm VM boot, network reachability and documented RPO/RTO expectations.
  2. Inject a controlled failure and measure last committed recoverable write and time to restore service.
  3. Initiate regional failover in staging and compare latest replicated transactions with primary commit history.
  4. Test regional dependency removal and verify service can operate from the secondary region.

Explanation

Correct Answer

C:

The acceptance test is specific: Initiate regional failover in staging and compare latest replicated transactions with primary commit history. Its purpose is to establish that the proposed architecture works: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior.

Incorrect Answers

A:

The alternative test targets: Design Azure Site Recovery replication for supported VMs, target networking and a tested recovery plan. The scenario's actual proposed remedy is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. Verify that one by: Initiate regional failover in staging and compare latest replicated transactions with primary commit history.

B:

This check validates a different workload: Inject a controlled failure and measure last committed recoverable write and time to restore service. Its associated design is: Use the declared RPO and RTO to select a realistic continuous replication, backup or multi-region architecture. The required acceptance test here is: Initiate regional failover in staging and compare latest replicated transactions with primary commit history.

D:

The alternative test targets: Add appropriate cross-region replication and failover design in addition to zone-level high availability. The scenario's actual proposed remedy is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. Verify that one by: Initiate regional failover in staging and compare latest replicated transactions with primary commit history.

Question 575

During architecture troubleshooting, a team reports: Applications remain pinned to a lost primary server endpoint after SQL recovery. Context: A banking SQL database should recover from an entire regional outage with consistent client routing and an understood asynchronous replication-loss window. Which underlying design mistake explains the observed behavior most precisely?

  1. Regional DR replication and orchestrated recovery were not configured for the workloads.
  2. Recovery-point frequency was not assessed against the business RPO.
  3. Availability zones are failure domains inside one region rather than independent geographic sites.
  4. The database regional failover and application endpoint strategy were not designed together.

Explanation

Correct Answer

D:

The recorded behavior follows from: The database regional failover and application endpoint strategy were not designed together. The appropriate mitigation would be: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. Verify with: Initiate regional failover in staging and compare latest replicated transactions with primary commit history.

Incorrect Answers

A:

The alternative weakness is: Regional DR replication and orchestrated recovery were not configured for the workloads. Its associated failure is: After a regional outage, engineers have only VM snapshots in the unavailable primary region.

The mechanism for that event is: Recovery-point frequency was not assessed against the business RPO. Here the stated symptom is: Applications remain pinned to a lost primary server endpoint after SQL recovery. Its cause is: The database regional failover and application endpoint strategy were not designed together.

C:

The proposed diagnosis fits another scenario: Availability zones are failure domains inside one region rather than independent geographic sites. It would typically be reflected by: All zonally redundant resources become unavailable when the full Azure region fails. The current evidence instead supports: The database regional failover and application endpoint strategy were not designed together.

Question 576

The design change is: Design Azure SQL failover groups or appropriate geo-replication with an explicit application-level RPO and listener behavior. The original failure was: Applications remain pinned to a lost primary server endpoint after SQL recovery. Which ongoing control best prevents recurrence of the same root cause?

  1. Rehearse the secondary listener and replication lag under representative load.
  2. Measure both RPO and RTO during every recovery exercise rather than assuming vendor defaults.
  3. Evaluate zone and region failure scenarios separately during reliability reviews.
  4. Schedule non-disruptive test failovers and monitor replication health and recovery plans.

Explanation

Correct Answer

A:

The key follow-up control is: Rehearse the secondary listener and replication lag under representative load. It avoids recurrence of the scenario in which: Applications remain pinned to a lost primary server endpoint after SQL recovery. It addresses: The database regional failover and application endpoint strategy were not designed together.

Incorrect Answers

B:

That safeguard manages another risk: Recovery-point frequency was not assessed against the business RPO. Its scenario is: An annual backup is approved despite a fifteen-minute maximum data-loss requirement. The present recurring risk is: The database regional failover and application endpoint strategy were not designed together. The proper ongoing control is: Rehearse the secondary listener and replication lag under representative load.

C:

D:

The proposed control focuses on: Regional DR replication and orchestrated recovery were not configured for the workloads. For the design in the question, recurrence comes from: The database regional failover and application endpoint strategy were not designed together. A precise prevention step is: Rehearse the secondary listener and replication lag under representative load.

Question 577

A design workshop has this requirement: A cloud application has three availability zones but the architecture review falsely claims this is enough to survive complete loss of the Azure region. Operators currently observe: All zonally redundant resources become unavailable when the full Azure region fails. Select the ONE design remedy that best addresses the root cause.

  1. Add appropriate cross-region replication and failover design in addition to zone-level high availability.
  2. Design Azure Site Recovery replication for supported VMs, target networking and a tested recovery plan.
  3. Choose supported geo-redundant Azure Backup vault storage and cross-region restore if eligible and required.
  4. Use the declared RPO and RTO to select a realistic continuous replication, backup or multi-region architecture.

Explanation

Correct Answer

A:

This option addresses the actual design defect: Availability zones are failure domains inside one region rather than independent geographic sites. The correction is: Add appropriate cross-region replication and failover design in addition to zone-level high availability. Confirm the outcome with: Test regional dependency removal and verify service can operate from the secondary region.

Incorrect Answers

B:

This choice mitigates an alternative scenario, where: After a regional outage, engineers have only VM snapshots in the unavailable primary region.

Here the root issue is: Availability zones are failure domains inside one region rather than independent geographic sites. Choose the corresponding action: Add appropriate cross-region replication and failover design in addition to zone-level high availability.

C:

The option belongs to a different failure mechanism: Vault storage redundancy and cross-region recovery capabilities do not meet the regional RTO requirement. That situation exhibits: Every restore copy remains dependent on the primary region's availability. For the stated case, the remedy is: Add appropriate cross-region replication and failover design in addition to zone-level high availability.

D:

That design instead addresses another observed condition: An annual backup is approved despite a fifteen-minute maximum data-loss requirement.
