Microsoft AZ-305 Practice Test 53

Question 520

A design review identifies: An analytics service stores blob objects that change frequently and must recover deleted or modified objects without restoring an entire storage account. The failure is: A developer's bulk overwrite cannot be recovered to an earlier object state. Select TWO distinct decisions that together provide the immediate technical solution AND an ongoing prevention control. A verification-only step does not replace either responsibility.

  1. Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable.
  2. Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.
  3. Audit backup policy and eligible storage account features after account configuration changes.
  4. Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.
  5. Test restore procedures and retention windows as datasets and transaction rates grow.

Explanation

Correct Answers

A:

This option addresses the actual design defect: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. The correction is: Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable. Confirm the outcome with: Delete a sample blob and execute an eligible point-in-time restore within the configured supported window.

C:

The key follow-up control is: Audit backup policy and eligible storage account features after account configuration changes. It avoids recurrence of the scenario in which: A developer's bulk overwrite cannot be recovered to an earlier object state. It addresses: Object-level restore prerequisites such as change feed/versioning/retention were not enabled.

Incorrect Answers

B:

This choice mitigates an alternative scenario, where: Deleting the source storage account compromises every local operational restore point. The underlying issue there is: Backups were kept solely in the data source's operational protection boundary. Here the root issue is: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. Choose the corresponding action: Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable.

D:

That design instead addresses another observed condition: Engineers fail to recover because all replicas contain the same mistaken data. Its technical cause is: Readable replicas reproduce logical changes and are not substitutes for independent historic backups. The current workload exhibits: A developer's bulk overwrite cannot be recovered to an earlier object state. Its targeted remedy is: Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable.

E:

This is a reasonable safeguard for a different fault: The database's HA standby contains the accidental delete and cannot restore an earlier state. That different mechanism is: High availability was mistaken for a point-in-time data recovery solution. The original incident here instead arises from: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. The directly relevant safeguard is: Audit backup policy and eligible storage account features after account configuration changes.

Question 521

A design workshop has this requirement: A compliance application needs offsite protected long-term blob backups independent of the source storage account's primary-region lifecycle. Operators currently observe: Deleting the source storage account compromises every local operational restore point. Select the ONE design remedy that best addresses the root cause.

  1. Configure Azure SQL long-term retention backup policy appropriate for the required years.
  2. Choose supported geo-redundant Azure Backup vault storage and cross-region restore if eligible and required.
  3. Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.
  4. Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable.

Explanation

Correct Answer

C:

This option addresses the actual design defect: Backups were kept solely in the data source's operational protection boundary. The correction is: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies. Confirm the outcome with: Restore sample protected data from the backup vault into a supported recovery destination.

Incorrect Answers

A:

This choice mitigates an alternative scenario, where: Mandatory audit-year records are unavailable because operational backups expired. The underlying issue there is: Only short-term PITR was configured instead of long-term backup retention. Here the root issue is: Backups were kept solely in the data source's operational protection boundary. Choose the corresponding action: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

B:

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: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

D:

This choice mitigates an alternative scenario, where: A developer's bulk overwrite cannot be recovered to an earlier object state. The underlying issue there is: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. Here the root issue is: Backups were kept solely in the data source's operational protection boundary. Choose the corresponding action: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

Question 522

The planned architecture is: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies. Workload context: A compliance application needs offsite protected long-term blob backups independent of the source storage account's primary-region lifecycle. Which acceptance test demonstrates that the required behavior works?

  1. Delete a sample blob and execute an eligible point-in-time restore within the configured supported window.
  2. Locate an old LTR backup in a test and validate that restore operations and approvals work.
  3. Verify cross-region restore entitlement and successfully test an eligible secondary-region VM restore.
  4. Restore sample protected data from the backup vault into a supported recovery destination.

Explanation

Correct Answer

D:

The acceptance test is specific: Restore sample protected data from the backup vault into a supported recovery destination. Its purpose is to establish that the proposed architecture works: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

Incorrect Answers

A:

That observation pertains to a separate failure: A developer's bulk overwrite cannot be recovered to an earlier object state. Its cause is: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. It does not confirm the result of this design. The direct proof would be: Restore sample protected data from the backup vault into a supported recovery destination.

B:

The alternative test targets: Configure Azure SQL long-term retention backup policy appropriate for the required years. The scenario's actual proposed remedy is: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies. Verify that one by: Restore sample protected data from the backup vault into a supported recovery destination.

C:

This check validates a different workload: Verify cross-region restore entitlement and successfully test an eligible secondary-region VM restore. Its associated design is: Choose supported geo-redundant Azure Backup vault storage and cross-region restore if eligible and required. The required acceptance test here is: Restore sample protected data from the backup vault into a supported recovery destination.

Question 523

The customer states: A compliance application needs offsite protected long-term blob backups independent of the source storage account's primary-region lifecycle. An incident reveals: Deleting the source storage account compromises every local operational restore point. What cause best accounts for this evidence?

  1. Object-level restore prerequisites such as change feed/versioning/retention were not enabled.
  2. Only short-term PITR was configured instead of long-term backup retention.
  3. Vault storage redundancy and cross-region recovery capabilities do not meet the regional RTO requirement.
  4. Backups were kept solely in the data source's operational protection boundary.

Explanation

Correct Answer

D:

This is the failure mechanism rather than an incidental symptom: Backups were kept solely in the data source's operational protection boundary. It accounts for: Deleting the source storage account compromises every local operational restore point. The architectural repair is: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

Incorrect Answers

A:

The proposed diagnosis fits another scenario: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. It would typically be reflected by: A developer's bulk overwrite cannot be recovered to an earlier object state. The current evidence instead supports: Backups were kept solely in the data source's operational protection boundary.

B:

The alternative weakness is: Only short-term PITR was configured instead of long-term backup retention. Its associated failure is: Mandatory audit-year records are unavailable because operational backups expired. Neither explains the present observation: Deleting the source storage account compromises every local operational restore point. The direct cause here is: Backups were kept solely in the data source's operational protection boundary.

C:

This cause would explain a different symptom: Every restore copy remains dependent on the primary region's availability. The mechanism for that event is: Vault storage redundancy and cross-region recovery capabilities do not meet the regional RTO requirement. Here the stated symptom is: Deleting the source storage account compromises every local operational restore point. Its cause is: Backups were kept solely in the data source's operational protection boundary.

Question 524

Workload context: A compliance application needs offsite protected long-term blob backups independent of the source storage account's primary-region lifecycle. The implemented remedy is: Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies. Which ongoing practice most specifically prevents recurrence of this failure: Deleting the source storage account compromises every local operational restore point.?

  1. Verify backup-vault protection/restore eligibility and separation-of-duties access.
  2. Audit backup policy and eligible storage account features after account configuration changes.
  3. Review availability and eligibility of cross-region restore before changing redundancy settings.
  4. Track LTR expiry and restore permissions for compliance audits.

Explanation

Correct Answer

A:

This is an ongoing protection specific to the fault: Verify backup-vault protection/restore eligibility and separation-of-duties access. The recurrence risk is: Backups were kept solely in the data source's operational protection boundary. It should be checked using: Restore sample protected data from the backup vault into a supported recovery destination.

Incorrect Answers

B:

The proposed control focuses on: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. For the design in the question, recurrence comes from: Backups were kept solely in the data source's operational protection boundary. A precise prevention step is: Verify backup-vault protection/restore eligibility and separation-of-duties access.

C:

That safeguard manages another risk: Vault storage redundancy and cross-region recovery capabilities do not meet the regional RTO requirement. Its scenario is: Every restore copy remains dependent on the primary region's availability. The present recurring risk is: Backups were kept solely in the data source's operational protection boundary. The proper ongoing control is: Verify backup-vault protection/restore eligibility and separation-of-duties access.

D:

This is a reasonable safeguard for a different fault: Mandatory audit-year records are unavailable because operational backups expired. That different mechanism is: Only short-term PITR was configured instead of long-term backup retention. The original incident here instead arises from: Backups were kept solely in the data source's operational protection boundary. The directly relevant safeguard is: Verify backup-vault protection/restore eligibility and separation-of-duties access.

Question 525

A solution architect is reviewing a workload: A finance database's erroneous update was copied to read replicas, but the team needs its state just before the transaction. The observed incident is: Engineers fail to recover because all replicas contain the same mistaken data. Which architecture choice most directly removes the identified weakness?

  1. Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.
  2. Design a PostgreSQL Flexible Server point-in-time restore and retention strategy for an eligible server.
  3. Design supported operational backup for Azure Blobs with versioning, soft delete and point-in-time restore prerequisites as applicable.
  4. Use Azure Backup for VM recovery points through an appropriate Recovery Services vault and backup policy.

Explanation

Correct Answer

A:

The targeted implementation is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database. The problem is not generic resource availability: Readable replicas reproduce logical changes and are not substitutes for independent historic backups. Verify the result by: Restore to the pre-update timestamp and verify rows while production remains unaffected.

Incorrect Answers

B:

That design instead addresses another observed condition: The database's HA standby contains the accidental delete and cannot restore an earlier state. Its technical cause is: High availability was mistaken for a point-in-time data recovery solution. The current workload exhibits: Engineers fail to recover because all replicas contain the same mistaken data. Its targeted remedy is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.

C:

This choice mitigates an alternative scenario, where: A developer's bulk overwrite cannot be recovered to an earlier object state. The underlying issue there is: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. Here the root issue is: Readable replicas reproduce logical changes and are not substitutes for independent historic backups. Choose the corresponding action: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.

D:

The option belongs to a different failure mechanism: A periodic backup/retention policy was not established for recovery from logical damage. That situation exhibits: Operations rely on one copied VM image that cannot return to an earlier date. For the stated case, the remedy is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.

Question 526

An architect proposes this change: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database. The workload context is: A finance database's erroneous update was copied to read replicas, but the team needs its state just before the transaction. Which evidence would most directly validate the change?

  1. Restore a nonproduction VM from a selected restore point and verify critical application data.
  2. Delete a sample blob and execute an eligible point-in-time restore within the configured supported window.
  3. Restore to the pre-update timestamp and verify rows while production remains unaffected.
  4. Perform a restore to just before the bad transaction and confirm the recovered dataset.

Explanation

Correct Answer

C:

The acceptance test is specific: Restore to the pre-update timestamp and verify rows while production remains unaffected. Its purpose is to establish that the proposed architecture works: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.

Incorrect Answers

A:

The alternative test targets: Use Azure Backup for VM recovery points through an appropriate Recovery Services vault and backup policy.

The scenario's actual proposed remedy is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database. Verify that one by: Restore to the pre-update timestamp and verify rows while production remains unaffected.

Question 527

During architecture troubleshooting, a team reports: Engineers fail to recover because all replicas contain the same mistaken data. Context: A finance database's erroneous update was copied to read replicas, but the team needs its state just before the transaction. Which underlying design mistake explains the observed behavior most precisely?

  1. Object-level restore prerequisites such as change feed/versioning/retention were not enabled.
  2. Readable replicas reproduce logical changes and are not substitutes for independent historic backups.
  3. A periodic backup/retention policy was not established for recovery from logical damage.
  4. High availability was mistaken for a point-in-time data recovery solution.

Explanation

Correct Answer

B:

The incident is explained by: Readable replicas reproduce logical changes and are not substitutes for independent historic backups. The reported symptom is: Engineers fail to recover because all replicas contain the same mistaken data. The corresponding design fix is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database.

Incorrect Answers

A:

The alternative weakness is: Object-level restore prerequisites such as change feed/versioning/retention were not enabled. Its associated failure is: A developer's bulk overwrite cannot be recovered to an earlier object state.

The direct cause here is: Readable replicas reproduce logical changes and are not substitutes for independent historic backups.

Question 528

The design change is: Use Azure SQL point-in-time restore from automated backups to a distinct recovery database. The original failure was: Engineers fail to recover because all replicas contain the same mistaken data. Which ongoing control best prevents recurrence of the same root cause?

  1. Audit backup policy and eligible storage account features after account configuration changes.
  2. Run periodic point-in-time drills with realistic accidental update scenarios.
  3. Test restore procedures and retention windows as datasets and transaction rates grow.
  4. Monitor backup job success and test restore points each quarter.

Explanation

Correct Answer

B:

The preventive control is: Run periodic point-in-time drills with realistic accidental update scenarios. It targets the earlier cause: Readable replicas reproduce logical changes and are not substitutes for independent historic backups. Confirm ongoing effectiveness by: Restore to the pre-update timestamp and verify rows while production remains unaffected.

Incorrect Answers

A:

The proposed control focuses on: Object-level restore prerequisites such as change feed/versioning/retention were not enabled.

A precise prevention step is: Run periodic point-in-time drills with realistic accidental update scenarios.

Question 529

A design workshop has this requirement: A regulated SQL workload needs backups for seven years, despite day-to-day restore windows of only weeks. Operators currently observe: Mandatory audit-year records are unavailable because operational backups expired. Select the ONE design remedy that best addresses the root cause.

  1. Use Azure Backup Policy and Azure Policy-based backup configuration where supported to enforce vault enrollment.
  2. Use supported immutable blob retention or backup vault immutability rather than rely on soft-delete alone.
  3. Configure Azure SQL long-term retention backup policy appropriate for the required years.
  4. Use a supported Azure Backup vaulted backup strategy for Azure Blobs with eligible account types and policies.

Explanation

Correct Answer

C:

The targeted implementation is: Configure Azure SQL long-term retention backup policy appropriate for the required years. The problem is not generic resource availability: Only short-term PITR was configured instead of long-term backup retention. Verify the result by: Locate an old LTR backup in a test and validate that restore operations and approvals work.

Incorrect Answers

A:

That design instead addresses another observed condition: New VMs routinely run for months without a backup schedule. Its technical cause is: Backup enrollment depends on manual provisioning rather than policy-driven governance. The current workload exhibits: Mandatory audit-year records are unavailable because operational backups expired. Its targeted remedy is: Configure Azure SQL long-term retention backup policy appropriate for the required years.

B:

This choice mitigates an alternative scenario, where: An administrator removes evidence before the required minimum retention date. The underlying issue there is: Soft-delete recovery does not itself enforce irreversible time-based immutability. Here the root issue is: Only short-term PITR was configured instead of long-term backup retention. Choose the corresponding action: Configure Azure SQL long-term retention backup policy appropriate for the required years.

D:

That design instead addresses another observed condition: Deleting the source storage account compromises every local operational restore point. Its technical cause is: Backups were kept solely in the data source's operational protection boundary. The current workload exhibits: Mandatory audit-year records are unavailable because operational backups expired. Its targeted remedy is: Configure Azure SQL long-term retention backup policy appropriate for the required years.

Question 530

The planned architecture is: Configure Azure SQL long-term retention backup policy appropriate for the required years. Workload context: A regulated SQL workload needs backups for seven years, despite day-to-day restore windows of only weeks. Which acceptance test demonstrates that the required behavior works?

  1. Try deleting or changing an eligible protected recovery object and verify its immutable retention boundary.
  2. Locate an old LTR backup in a test and validate that restore operations and approvals work.
  3. Deploy a newly tagged test VM and verify expected backup policy assignment and first recovery point.
  4. Restore sample protected data from the backup vault into a supported recovery destination.

Explanation

Correct Answer

B:

The acceptance test is specific: Locate an old LTR backup in a test and validate that restore operations and approvals work. Its purpose is to establish that the proposed architecture works: Configure Azure SQL long-term retention backup policy appropriate for the required years.
