Microsoft AZ-305 Practice Test 54
Question 530
An architecture proposal for rpo and rto engineering relies on the following approach: Accept the vendor's guarantee without dependency or failure-mode analysis. Which specific failure or mismatch should the design reviewer identify?
- A single point of failure invalidates the proposed service objective.
- Constant standby costs may exceed the recovery benefit.
- RTO does not define how much committed data may be lost.
- The attacker could destroy recovery points and evade detection.
Explanation
Correct Answer
A:Accept the vendor's guarantee without dependency or failure-mode analysis. A single point of failure invalidates the proposed service objective.
Incorrect Answers
B:That assessment refers to the separate proposal 'Deploy permanent duplicate hot compute in every region without business need.' not to the recommendation under review. Here, A single point of failure invalidates the proposed service objective.
C:That assessment refers to the separate proposal 'Interpret one-hour recovery time as permission to lose one hour of data.' not to the recommendation under review. Here, A single point of failure invalidates the proposed service objective.
D:This concern applies to Give the compromised account unlimited purge rights and disable alerts. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because a single point of failure invalidates the proposed service objective.
Question 531
Acceptance testing must establish the following operational result: Measured service interruption exposes unrealistic contracts. Which verification action most directly establishes that outcome?
- Model annual standby cost against observed restore time and data loss.
- Measure last recoverable transaction and service restoration time in a drill.
- Attempt a protected-item destructive operation in an isolated vault.
- Run destructive failover exercises including upstream dependencies.
Explanation
Correct Answer
D:Measured service interruption exposes unrealistic contracts.
Incorrect Answers
A:That verification addresses the different requirement: A low-priority archive application tolerates a 24-hour outage and a day of lost writes. It does not directly establish measured service interruption exposes unrealistic contracts.
B:That verification addresses the different requirement: A payments service permits fifteen minutes of data loss but must recover within one hour. It does not directly establish measured service interruption exposes unrealistic contracts.
C:This is a test for A compromised backup operator should not be able to immediately destroy protected recovery points. The requirement here is instead demonstrated by run destructive failover exercises including upstream dependencies.
Question 532
A business has replication but no documented process for DNS, secrets and database failover. Which Azure architecture choice best meets this requirement?
- Mark DR as compliant merely because the architecture diagram exists.
- Build an application-level DR runbook covering dependent services.
- Treat a healthy replica as proof the user-facing service automatically works.
- Configure only VM disk replication and ignore target networking.
Explanation
Correct Answer
B:Recovering VMs alone does not guarantee reachable, authenticated application function.
Incorrect Answers
A:An untested diagram cannot prove failover timing or data recovery. In the present requirement, a business has replication but no documented process for DNS, secrets and database failover. The needed design instead works because recovering VMs alone does not guarantee reachable, authenticated application function.
C:Replica health excludes DNS, application state and authentication dependencies. This proposal contradicts the stated architecture constraint.
D:A recovered VM without dependencies may remain unreachable. In the present requirement, a business has replication but no documented process for DNS, secrets and database failover. The needed design instead works because recovering VMs alone does not guarantee reachable, authenticated application function.
Question 533
An architecture proposal for dr runbooks and recovery testing relies on the following approach: Treat a healthy replica as proof the user-facing service automatically works. Which specific failure or mismatch should the design reviewer identify?
- An untested diagram cannot prove failover timing or data recovery.
- Live replicas may contain the same erroneous write.
- Replica health excludes DNS, application state and authentication dependencies.
- A recovered VM without dependencies may remain unreachable.
Explanation
Correct Answer
C:Treat a healthy replica as proof the user-facing service automatically works. Replica health excludes DNS, application state and authentication dependencies.
Incorrect Answers
A:That assessment refers to the separate proposal 'Mark DR as compliant merely because the architecture diagram exists.' not to the recommendation under review. Here, Replica health excludes DNS, application state and authentication dependencies.
B:This concern applies to Use only geo-replicated live databases as the sole immutable recovery source. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because replica health excludes DNS, application state and authentication dependencies.
D:That assessment refers to the separate proposal 'Configure only VM disk replication and ignore target networking.' not to the recommendation under review. Here, Replica health excludes DNS, application state and authentication dependencies.
Question 534
Acceptance testing must establish the following operational result: User-path validation establishes real operational recovery. Which verification action most directly establishes that outcome?
- Inject a test bad update and restore from a pre-change backup.
- Test private endpoint, DNS and routing from recovery workloads.
- Compare each exercise result with its contractual objectives and closure record.
- Execute the full business transaction after an isolated failover.
Explanation
Correct Answer
D:User-path validation establishes real operational recovery.
Incorrect Answers
A:This is a test for An operations team expects active geo-replication to protect against a malicious data update. The requirement here is instead demonstrated by execute the full business transaction after an isolated failover.
B:That verification addresses the different requirement: A DR exercise fails because the replacement region lacks required IP ranges and connectivity. It does not directly establish user-path validation establishes real operational recovery.
C:That verification addresses the different requirement: A regulator requires demonstrable disaster readiness rather than a written disaster plan. It does not directly establish user-path validation establishes real operational recovery.
Question 535
A DR exercise fails because the replacement region lacks required IP ranges and connectivity. Which Azure architecture choice best meets this requirement?
- Configure only VM disk replication and ignore target networking.
- Reserve and validate target-region networking and name resolution ahead of failover.
- Mark DR as compliant merely because the architecture diagram exists.
- Treat a healthy replica as proof the user-facing service automatically works.
Explanation
Correct Answer
B:Regional recovery depends on routable address and private-service reachability.
Incorrect Answers
A:A recovered VM without dependencies may remain unreachable. This proposal contradicts the stated architecture constraint.
C:An untested diagram cannot prove failover timing or data recovery. In the present requirement, a DR exercise fails because the replacement region lacks required IP ranges and connectivity. The needed design instead works because regional recovery depends on routable address and private-service reachability.
D:Replica health excludes DNS, application state and authentication dependencies. In the present requirement, a DR exercise fails because the replacement region lacks required IP ranges and connectivity. The needed design instead works because regional recovery depends on routable address and private-service reachability.

Correct Answer
C:Rehearsals expose untested assumptions and show repeatable recovery behavior.
Incorrect Answers
A:An untested diagram cannot prove failover timing or data recovery. This proposal contradicts the stated architecture constraint.
