Microsoft AZ-305 Practice Test 46
Question 450
Acceptance testing must establish the following operational result: A fault-injection test proves backpressure and recovery behavior. Which verification action most directly establishes that outcome?
- Load-test partition throughput and independent consumer checkpoints.
- Force HTTP 429 responses and validate resumed processing without duplicates.
- Modify and delete representative records and inspect incremental results.
- Inject synthetic high-temperature events and inspect processing latency.
Explanation
Correct Answer
B:A fault-injection test proves backpressure and recovery behavior.
Incorrect Answers
A:This is a test for Millions of IoT sensor events per hour must be ingested with parallel consumers. The requirement here is instead demonstrated by force HTTP 429 responses and validate resumed processing without duplicates.
C:That verification addresses the different requirement: A nightly warehouse load should process only records changed since the prior successful run. It does not directly establish a fault-injection test proves backpressure and recovery behavior.
D:That verification addresses the different requirement: A real-time dashboard must aggregate sensor anomalies continuously while raw events arrive. It does not directly establish a fault-injection test proves backpressure and recovery behavior.
Question 451
An Azure VM requires recoverable daily and long-term restore points protected from ordinary application operators. Which TWO designs belong in the backup plan? (Select TWO.)
- Treat VM availability zones as backups of previously deleted files.
- Protect the VM in an Azure Backup vault with an appropriate backup and retention policy.
- Store the only backup on the same writable VM OS disk.
- Grant every app operator unlimited backup-purge authority.
- Separate vault deletion privileges and enable eligible recovery safeguards.
Explanation
Correct Answers
B:Vault policies create recoverable points independent of the live VM.
E:Restricted roles and protections reduce intentional backup destruction.
Incorrect Answers
A:Availability is not historical recovery.
C:A local compromise could destroy both primary and backup.
D:Broad deletion rights contradict protected recovery.
Question 452
An architecture proposal for azure backup vault architecture relies on the following approach: Assume VM availability zones alone create recoverable historical versions. Which specific failure or mismatch should the design reviewer identify?
- An OS disk failure can destroy primary and purported backup simultaneously.
- Availability protects service uptime, not accidental file deletion history.
- Unrestricted deletion defeats the independent recovery control.
- Default resolution can pick one winner and may not preserve all conflicts.
Explanation
Correct Answer
B:Assume VM availability zones alone create recoverable historical versions. Availability protects service uptime, not accidental file deletion history.
Incorrect Answers
A:That assessment refers to the separate proposal 'Keep all protected copies solely on the same VM OS disk.' not to the recommendation under review. Here, Availability protects service uptime, not accidental file deletion history.
C:That assessment refers to the separate proposal 'Assign every workload operator unlimited vault backup deletion permissions.' not to the recommendation under review. Here, Availability protects service uptime, not accidental file deletion history.
D:This concern applies to Assume multi-write means every conflicting version is retained automatically forever. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because availability protects service uptime, not accidental file deletion history.
Question 453
Acceptance testing must establish the following operational result: A successful boot and file recovery establish that backup data is usable. Which verification action most directly establishes that outcome?
- Attempt a nonproduction protected-item deletion with a restricted identity.
- Perform a test VM restore into an isolated recovery network.
- Inspect vault redundancy and execute a controlled cross-region restore where supported.
- Submit controlled competing updates and inspect resolved document state.
Explanation
Correct Answer
B:A successful boot and file recovery establish that backup data is usable.
Incorrect Answers
A:That verification addresses the different requirement: A backup team wants one retention policy across projects but application owners must not delete protected data. It does not directly establish a successful boot and file recovery establish that backup data is usable.
C:That verification addresses the different requirement: A platform runs multiple regions and requires recovery data held outside the workload region. It does not directly establish a successful boot and file recovery establish that backup data is usable.
D:This is a test for A globally writable Cosmos database needs deterministic conflict behavior during multi-region writes. The requirement here is instead demonstrated by perform a test VM restore into an isolated recovery network.
Question 454
A platform runs multiple regions and requires recovery data held outside the workload region. Which Azure architecture choice best meets this requirement?
- Assume VM availability zones alone create recoverable historical versions.
- Select a supported vault and backup storage redundancy strategy aligned to regional risk.
- Assign every workload operator unlimited vault backup deletion permissions.
- Keep all protected copies solely on the same VM OS disk.
Explanation
Correct Answer
B:Vault storage configuration determines geo and zonal protection capabilities for protected data.
Incorrect Answers
A:Availability protects service uptime, not accidental file deletion history. In the present requirement, a platform runs multiple regions and requires recovery data held outside the workload region. The needed design instead works because vault storage configuration determines geo and zonal protection capabilities for protected data.
C:Unrestricted deletion defeats the independent recovery control. In the present requirement, a platform runs multiple regions and requires recovery data held outside the workload region. The needed design instead works because vault storage configuration determines geo and zonal protection capabilities for protected data.
D:An OS disk failure can destroy primary and purported backup simultaneously. This proposal contradicts the stated architecture constraint.
Question 455
An architecture proposal for azure backup vault architecture relies on the following approach: Keep all protected copies solely on the same VM OS disk. Which specific failure or mismatch should the design reviewer identify?
- RTO does not define how much committed data may be lost.
- Availability protects service uptime, not accidental file deletion history.
- Unrestricted deletion defeats the independent recovery control.
- An OS disk failure can destroy primary and purported backup simultaneously.
Explanation
Correct Answer
D:Keep all protected copies solely on the same VM OS disk. An OS disk failure can destroy primary and purported backup simultaneously.
Incorrect Answers
A:This concern applies to Interpret one-hour recovery time as permission to lose one hour of data. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because an OS disk failure can destroy primary and purported backup simultaneously.
B:That assessment refers to the separate proposal 'Assume VM availability zones alone create recoverable historical versions.' not to the recommendation under review. Here, An OS disk failure can destroy primary and purported backup simultaneously.
C:That assessment refers to the separate proposal 'Assign every workload operator unlimited vault backup deletion permissions.' not to the recommendation under review. Here, An OS disk failure can destroy primary and purported backup simultaneously.
Question 456
Acceptance testing must establish the following operational result: Configuration and restoration prove the recovery location is practical. Which verification action most directly establishes that outcome?
- Attempt a nonproduction protected-item deletion with a restricted identity.
- Perform a test VM restore into an isolated recovery network.
- Measure last recoverable transaction and service restoration time in a drill.
- Inspect vault redundancy and execute a controlled cross-region restore where supported.
Explanation
Correct Answer
D:Configuration and restoration prove the recovery location is practical.
Incorrect Answers
A:That verification addresses the different requirement: A backup team wants one retention policy across projects but application owners must not delete protected data. It does not directly establish configuration and restoration prove the recovery location is practical.
B:That verification addresses the different requirement: A company needs policy-based recovery points for supported Azure VMs without writing snapshot scripts. It does not directly establish configuration and restoration prove the recovery location is practical.
C:This is a test for A payments service permits fifteen minutes of data loss but must recover within one hour. The requirement here is instead demonstrated by inspect vault redundancy and execute a controlled cross-region restore where supported.
Question 457
A backup team wants one retention policy across projects but application owners must not delete protected data. Which Azure architecture choice best meets this requirement?
- Separate backup policy administration from vault protection and deletion permissions.

- Assume VM availability zones alone create recoverable historical versions.
Explanation
Correct Answer
A:Backup governance reduces destructive changes by workload operators.
Incorrect Answers
B:Unrestricted deletion defeats the independent recovery control. This proposal contradicts the stated architecture constraint.
C:An OS disk failure can destroy primary and purported backup simultaneously. In the present requirement, a backup team wants one retention policy across projects but application owners must not delete protected data. The needed design instead works because backup governance reduces destructive changes by workload operators.
D:Availability protects service uptime, not accidental file deletion history. In the present requirement, a backup team wants one retention policy across projects but application owners must not delete protected data. The needed design instead works because backup governance reduces destructive changes by workload operators.
Question 458
An architecture proposal for azure backup vault architecture relies on the following approach: Assign every workload operator unlimited vault backup deletion permissions. Which specific failure or mismatch should the design reviewer identify?
- Incorrect order can leave the app unavailable even if all VMs boot.
- Availability protects service uptime, not accidental file deletion history.
- An OS disk failure can destroy primary and purported backup simultaneously.
- Unrestricted deletion defeats the independent recovery control.
Explanation
Correct Answer
D:Assign every workload operator unlimited vault backup deletion permissions. Unrestricted deletion defeats the independent recovery control.
Incorrect Answers
A:This concern applies to Start application servers before their required data layer without network preparation. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because unrestricted deletion defeats the independent recovery control.
B:That assessment refers to the separate proposal 'Assume VM availability zones alone create recoverable historical versions.' not to the recommendation under review. Here, Unrestricted deletion defeats the independent recovery control.
C:That assessment refers to the separate proposal 'Keep all protected copies solely on the same VM OS disk.' not to the recommendation under review. Here, Unrestricted deletion defeats the independent recovery control.
Question 459
Acceptance testing must establish the following operational result: Denial demonstrates separation of responsibilities. Which verification action most directly establishes that outcome?
- Attempt a nonproduction protected-item deletion with a restricted identity.
- Inspect vault redundancy and execute a controlled cross-region restore where supported.
- Perform a test VM restore into an isolated recovery network.
- Test database, application and front-end failover sequence end to end.
Explanation
Correct Answer
A:Denial demonstrates separation of responsibilities.
Incorrect Answers
B:That verification addresses the different requirement: A platform runs multiple regions and requires recovery data held outside the workload region. It does not directly establish denial demonstrates separation of responsibilities.
C:That verification addresses the different requirement: A company needs policy-based recovery points for supported Azure VMs without writing snapshot scripts. It does not directly establish denial demonstrates separation of responsibilities.
D:This is a test for A DR plan must fail over three dependent application VMs in a defined order. The requirement here is instead demonstrated by attempt a nonproduction protected-item deletion with a restricted identity.
Question 460
A VM recovery requirement is four hours and backups are currently scheduled once each day. Which Azure architecture choice best meets this requirement?
- Claim daily backups guarantee at most four hours of data loss.
- Change backup frequency or protection design to meet the stated RPO.
- Assume copying a running datafile without consistency controls guarantees logical recovery.
- Keep only the newest daily backup and call it long-term archive.
Explanation
Correct Answer
B:A daily point-in-time backup may lose nearly a day's changes.
Incorrect Answers
A:Backup intervals set the achievable recovery-point exposure. This proposal contradicts the stated architecture constraint.
C:A raw copy may not provide a transaction-consistent restorable database. In the present requirement, a VM recovery requirement is four hours and backups are currently scheduled once each day. The needed design instead works because a daily point-in-time backup may lose nearly a day's changes.
D:A single recent recovery point cannot satisfy historic retention. In the present requirement, a VM recovery requirement is four hours and backups are currently scheduled once each day. The needed design instead works because a daily point-in-time backup may lose nearly a day's changes.
