Microsoft AZ-305 Practice Test 48
Question 470
An architecture proposal for azure site recovery azure vms relies on the following approach: Rely only on weekly VM backups for near-continuous regional failover. Which specific failure or mismatch should the design reviewer identify?
- Periodic backup points may exceed a tight RPO and require longer recovery.
- A single recent recovery point cannot satisfy historic retention.
- Incorrect order can leave the app unavailable even if all VMs boot.
- Actual failover unnecessarily disrupts business when an isolated test is available.
Explanation
Correct Answer
A:Rely only on weekly VM backups for near-continuous regional failover. Periodic backup points may exceed a tight RPO and require longer recovery.
Incorrect Answers
B:This concern applies to Keep only the newest daily backup and call it long-term archive. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because periodic backup points may exceed a tight RPO and require longer recovery.
C:That assessment refers to the separate proposal 'Start application servers before their required data layer without network preparation.' not to the recommendation under review. Here, Periodic backup points may exceed a tight RPO and require longer recovery.
D:That assessment refers to the separate proposal 'Trigger an unplanned production failover as the routine monthly test.' not to the recommendation under review. Here, Periodic backup points may exceed a tight RPO and require longer recovery.
Question 471
Acceptance testing must establish the following operational result: Recovery test proves the DR sequence and VM readiness. Which verification action most directly establishes that outcome?
- Complete test-failover cleanup and verify replication health.
- Run a non-disruptive ASR test failover and measure startup dependencies.
- Test database, application and front-end failover sequence end to end.
- List points from the requested years in the vault.
Explanation
Correct Answer
B:Recovery test proves the DR sequence and VM readiness.
Incorrect Answers
A:That verification addresses the different requirement: Operators need a DR rehearsal without interrupting production replicas. It does not directly establish recovery test proves the DR sequence and VM readiness.
C:That verification addresses the different requirement: A DR plan must fail over three dependent application VMs in a defined order. It does not directly establish recovery test proves the DR sequence and VM readiness.
D:This is a test for An audit demands monthly recovery points retained for several years. The requirement here is instead demonstrated by run a non-disruptive ASR test failover and measure startup dependencies.
Question 472
A DR plan must fail over three dependent application VMs in a defined order. Which Azure architecture choice best meets this requirement?
- Start application servers before their required data layer without network preparation.
- Use ASR recovery plans with ordered groups and approved automation steps.
- Rely only on weekly VM backups for near-continuous regional failover.
- Trigger an unplanned production failover as the routine monthly test.
Explanation
Correct Answer
B:Recovery plans coordinate dependency sequencing rather than boot all components randomly.
Incorrect Answers
A:Incorrect order can leave the app unavailable even if all VMs boot. This proposal contradicts the stated architecture constraint.
C:Periodic backup points may exceed a tight RPO and require longer recovery. In the present requirement, a DR plan must fail over three dependent application VMs in a defined order. The needed design instead works because recovery plans coordinate dependency sequencing rather than boot all components randomly.
D:Actual failover unnecessarily disrupts business when an isolated test is available. In the present requirement, a DR plan must fail over three dependent application VMs in a defined order. The needed design instead works because recovery plans coordinate dependency sequencing rather than boot all components randomly.

- Default resolution can pick one winner and may not preserve all conflicts.
- Actual failover unnecessarily disrupts business when an isolated test is available.
Explanation
Correct Answer
A:Start application servers before their required data layer without network preparation. Incorrect order can leave the app unavailable even if all VMs boot.
Incorrect Answers
B:That assessment refers to the separate proposal 'Rely only on weekly VM backups for near-continuous regional failover.' not to the recommendation under review. Here, Incorrect order can leave the app unavailable even if all VMs boot.
C: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 incorrect order can leave the app unavailable even if all VMs boot.

Question 474
Acceptance testing must establish the following operational result: Dependency verification establishes application-level recovery. Which verification action most directly establishes that outcome?
- Submit controlled competing updates and inspect resolved document state.
- Test database, application and front-end failover sequence end to end.
- Run a non-disruptive ASR test failover and measure startup dependencies.
- Complete test-failover cleanup and verify replication health.
Explanation
Correct Answer
B:Dependency verification establishes application-level recovery.
Incorrect Answers
A: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 test database, application and front-end failover sequence end to end.
C:That verification addresses the different requirement: A mission-critical VM must replicate to another Azure region with orchestrated failover. It does not directly establish dependency verification establishes application-level recovery.
D:That verification addresses the different requirement: Operators need a DR rehearsal without interrupting production replicas. It does not directly establish dependency verification establishes application-level recovery.
Question 475
Operators need a DR rehearsal without interrupting production replicas. Which Azure architecture choice best meets this requirement?
- Use ASR test failover in an isolated network with cleanup afterward.
- Rely only on weekly VM backups for near-continuous regional failover.
- Trigger an unplanned production failover as the routine monthly test.
- Start application servers before their required data layer without network preparation.
Explanation
Correct Answer
A:Test failover validates recovery state while the primary stays operational.
Incorrect Answers
B:Periodic backup points may exceed a tight RPO and require longer recovery. In the present requirement, operators need a DR rehearsal without interrupting production replicas. The needed design instead works because test failover validates recovery state while the primary stays operational.
C:Actual failover unnecessarily disrupts business when an isolated test is available. This proposal contradicts the stated architecture constraint.
D:Incorrect order can leave the app unavailable even if all VMs boot. In the present requirement, operators need a DR rehearsal without interrupting production replicas. The needed design instead works because test failover validates recovery state while the primary stays operational.
Question 476
An architecture proposal for azure site recovery azure vms relies on the following approach: Trigger an unplanned production failover as the routine monthly test. Which specific failure or mismatch should the design reviewer identify?

- Actual failover unnecessarily disrupts business when an isolated test is available.
- Periodic backup points may exceed a tight RPO and require longer recovery.
- Incorrect order can leave the app unavailable even if all VMs boot.
Explanation
Correct Answer
B:Trigger an unplanned production failover as the routine monthly test. Actual failover unnecessarily disrupts business when an isolated test is available.

Question 478
A physical on-premises Windows server must recover into Azure after a datacenter disaster. Which Azure architecture choice best meets this requirement?
- Place every VM in one indiscriminate high-priority recovery group.
- Power on the old site immediately without reconciling changed application data.
- Assess a supported Azure Site Recovery physical-server replication path.
- Expect Azure Backup daily file restore to provide immediate powered-on workload failover.
Explanation
Correct Answer
C:ASR can protect eligible physical or virtual machines depending on source topology.
Incorrect Answers
A:A uniform group ignores business criticality and dependent components. In the present requirement, a physical on-premises Windows server must recover into Azure after a datacenter disaster. The needed design instead works because aSR can protect eligible physical or virtual machines depending on source topology.
B:Split-brain writes can corrupt recovered business state. In the present requirement, a physical on-premises Windows server must recover into Azure after a datacenter disaster. The needed design instead works because aSR can protect eligible physical or virtual machines depending on source topology.
D:Backup recovery may be slower and is not automatically an active VM replica. This proposal contradicts the stated architecture constraint.
