Microsoft AZ-305 Practice Test 57
Question 560
An architecture proposal for sql zone-redundant ha relies on the following approach: Deploy a non-zonal database and assume application retries create zone replicas. Which specific failure or mismatch should the design reviewer identify?
- Autoscale can delete the only record of the session.
- Client retries do not introduce database zone redundancy.
- Read replicas cannot automatically meet synchronous failover requirements.
- Transport sessions may break while a new replica becomes primary.
Explanation
Correct Answer
B:Deploy a non-zonal database and assume application retries create zone replicas. Client retries do not introduce database zone redundancy.
Incorrect Answers
A:This concern applies to Store the only copy of user sessions on each scale-in eligible VM. in another design for high availability design. The current proposal specifically fails because client retries do not introduce database zone redundancy.
C:That assessment refers to the separate proposal 'Treat asynchronous reporting replicas as a zero-loss synchronous write quorum.' not to the recommendation under review. Here, Client retries do not introduce database zone redundancy.
D:That assessment refers to the separate proposal 'Assume active SQL connections never need retry logic after a failover.' not to the recommendation under review. Here, Client retries do not introduce database zone redundancy.
Question 561
Acceptance testing must establish the following operational result: Configuration and continuity prove the database tolerates zone loss. Which verification action most directly establishes that outcome?
- Induce an approved failover and inspect client transient-fault retries.
- Inspect zone-redundant setting and measure planned failover behavior.
- Compare architecture diagrams and run read/write/failover tests.
- Delete a worker during an active session and check continuity.
Explanation
Correct Answer
B:Configuration and continuity prove the database tolerates zone loss.
Incorrect Answers
A:That verification addresses the different requirement: A SQL service requires automatic local failover with predictable client reconnects. It does not directly establish configuration and continuity prove the database tolerates zone loss.
C:That verification addresses the different requirement: An application owner confuses SQL read replicas with synchronous transactional HA replicas. It does not directly establish configuration and continuity prove the database tolerates zone loss.
D:This is a test for A VMSS contains stateful sessions tied to local instance disks that cannot survive replacement. The requirement here is instead demonstrated by inspect zone-redundant setting and measure planned failover behavior.
Question 562
A SQL service requires automatic local failover with predictable client reconnects. Which Azure architecture choice best meets this requirement?
- Treat asynchronous reporting replicas as a zero-loss synchronous write quorum.
- Assume active SQL connections never need retry logic after a failover.
- Deploy a non-zonal database and assume application retries create zone replicas.
- Choose a service tier and retry policy suited to managed HA failover.
Explanation
Correct Answer
D:Even managed HA can produce transient connection interruptions.
Incorrect Answers
A:Read replicas cannot automatically meet synchronous failover requirements. In the present requirement, a SQL service requires automatic local failover with predictable client reconnects. The needed design instead works because even managed HA can produce transient connection interruptions.
B:Transport sessions may break while a new replica becomes primary. This proposal contradicts the stated architecture constraint.
C:Client retries do not introduce database zone redundancy. In the present requirement, a SQL service requires automatic local failover with predictable client reconnects. The needed design instead works because even managed HA can produce transient connection interruptions.
Question 563

- Read replicas cannot automatically meet synchronous failover requirements.
- Transport sessions may break while a new replica becomes primary.
- Manual remediation delays recovery under load.
- Client retries do not introduce database zone redundancy.
Explanation
Correct Answer
B:Assume active SQL connections never need retry logic after a failover. Transport sessions may break while a new replica becomes primary.
Incorrect Answers
A:That assessment refers to the separate proposal 'Treat asynchronous reporting replicas as a zero-loss synchronous write quorum.' not to the recommendation under review. Here, Transport sessions may break while a new replica becomes primary.
C:This concern applies to Manually provision each VM and detect failure only through user complaints. in another design for high availability design. The current proposal specifically fails because transport sessions may break while a new replica becomes primary.
D:That assessment refers to the separate proposal 'Deploy a non-zonal database and assume application retries create zone replicas.' not to the recommendation under review. Here, Transport sessions may break while a new replica becomes primary.
Question 564
Acceptance testing must establish the following operational result: Successful reconnects demonstrate application resilience. Which verification action most directly establishes that outcome?
- Compare architecture diagrams and run read/write/failover tests.
- Generate load and terminate a test instance while observing replacement.
- Inspect zone-redundant setting and measure planned failover behavior.
- Induce an approved failover and inspect client transient-fault retries.
Explanation
Correct Answer
D:Successful reconnects demonstrate application resilience.
Incorrect Answers
A:That verification addresses the different requirement: An application owner confuses SQL read replicas with synchronous transactional HA replicas. It does not directly establish successful reconnects demonstrate application resilience.
B:This is a test for A regional stateless web fleet must replace failed instances and scale on aggregate CPU. The requirement here is instead demonstrated by induce an approved failover and inspect client transient-fault retries.
C:That verification addresses the different requirement: A mission-critical SQL Database needs protection from a primary zone failure in a supported region. It does not directly establish successful reconnects demonstrate application resilience.
Question 565

- Keep read scale-out and high availability requirements separate during SQL tier selection.
- Treat asynchronous reporting replicas as a zero-loss synchronous write quorum.
- Assume active SQL connections never need retry logic after a failover.
- Deploy a non-zonal database and assume application retries create zone replicas.
Explanation
Correct Answer
A:Read-only scale replicas and zone redundancy solve different workloads.
Incorrect Answers
B:Read replicas cannot automatically meet synchronous failover requirements. This proposal contradicts the stated architecture constraint.
C:Transport sessions may break while a new replica becomes primary. In the present requirement, an application owner confuses SQL read replicas with synchronous transactional HA replicas. The needed design instead works because read-only scale replicas and zone redundancy solve different workloads.
D:Client retries do not introduce database zone redundancy. In the present requirement, an application owner confuses SQL read replicas with synchronous transactional HA replicas. The needed design instead works because read-only scale replicas and zone redundancy solve different workloads.
Question 566

- Client retries do not introduce database zone redundancy.
- Transport sessions may break while a new replica becomes primary.
- Simultaneous restarts cause avoidable full-service downtime.
- Read replicas cannot automatically meet synchronous failover requirements.
Explanation
Correct Answer
D:Treat asynchronous reporting replicas as a zero-loss synchronous write quorum. Read replicas cannot automatically meet synchronous failover requirements.
Incorrect Answers
A:That assessment refers to the separate proposal 'Deploy a non-zonal database and assume application retries create zone replicas.' not to the recommendation under review. Here, Read replicas cannot automatically meet synchronous failover requirements.
B:That assessment refers to the separate proposal 'Assume active SQL connections never need retry logic after a failover.' not to the recommendation under review. Here, Read replicas cannot automatically meet synchronous failover requirements.
C:This concern applies to Reboot all production instances at exactly the same instant. in another design for high availability design. The current proposal specifically fails because read replicas cannot automatically meet synchronous failover requirements.
Question 567
Acceptance testing must establish the following operational result: Endpoint behavior identifies each replica's function. Which verification action most directly establishes that outcome?
- Induce an approved failover and inspect client transient-fault retries.
- Perform a staged update and monitor healthy capacity throughout.
- Compare architecture diagrams and run read/write/failover tests.
- Inspect zone-redundant setting and measure planned failover behavior.
Explanation
Correct Answer
C:Endpoint behavior identifies each replica's function.
Incorrect Answers
A:That verification addresses the different requirement: A SQL service requires automatic local failover with predictable client reconnects. It does not directly establish endpoint behavior identifies each replica's function.
B:This is a test for A company wants uniform VM OS updates across a large instance fleet without taking the whole site down. The requirement here is instead demonstrated by compare architecture diagrams and run read/write/failover tests.
D:That verification addresses the different requirement: A mission-critical SQL Database needs protection from a primary zone failure in a supported region. It does not directly establish endpoint behavior identifies each replica's function.
Question 568
An application needs automatic regional SQL database failover under policy and a stable connection name. Which Azure architecture choice best meets this requirement?
- Claim listener automation guarantees cross-region synchronous durability.
- Point clients to a literal primary region host forever.
- Write transactions directly to an ordinary secondary read-only replica.
- Configure eligible Azure SQL failover groups with designed grace period and listener.
Explanation
Correct Answer
D:Failover-group listeners abstract the active region for clients.
Incorrect Answers
A:Routing abstraction does not change replication consistency. In the present requirement, an application needs automatic regional SQL database failover under policy and a stable connection name. The needed design instead works because failover-group listeners abstract the active region for clients.
B:Fixed endpoints create extra outage or manual reconfiguration after failover. This proposal contradicts the stated architecture constraint.
C:The secondary is not automatically a multi-writer SQL master. In the present requirement, an application needs automatic regional SQL database failover under policy and a stable connection name. The needed design instead works because failover-group listeners abstract the active region for clients.
Question 569
An architecture proposal for regional sql failover groups relies on the following approach: Point clients to a literal primary region host forever. Which specific failure or mismatch should the design reviewer identify?
- Routing abstraction does not change replication consistency.
- The secondary is not automatically a multi-writer SQL master.
- Fixed endpoints create extra outage or manual reconfiguration after failover.
- Static records cannot react immediately to application failure.
Explanation
Correct Answer
C:Point clients to a literal primary region host forever. Fixed endpoints create extra outage or manual reconfiguration after failover.
Incorrect Answers
A:That assessment refers to the separate proposal 'Claim listener automation guarantees cross-region synchronous durability.' not to the recommendation under review. Here, Fixed endpoints create extra outage or manual reconfiguration after failover.
B:That assessment refers to the separate proposal 'Write transactions directly to an ordinary secondary read-only replica.' not to the recommendation under review. Here, Fixed endpoints create extra outage or manual reconfiguration after failover.
D:This concern applies to Use static DNS records with no endpoint health evaluation as the only failover. in another design for high availability design. The current proposal specifically fails because fixed endpoints create extra outage or manual reconfiguration after failover.
Question 570
Acceptance testing must establish the following operational result: Client access validates routing resilience. Which verification action most directly establishes that outcome?
- Test reads and rejected writes at the secondary listener.
- Return HTTP 500 from one test backend and inspect traffic routing.
- Calculate loss exposure from real lag and write rate measurements.
- Rehearse failover and reconnect through the listener.
Explanation
Correct Answer
D:Client access validates routing resilience.
Incorrect Answers
A:That verification addresses the different requirement: Two regions must host SQL data but the second is allowed to be read-only before disaster. It does not directly establish client access validates routing resilience.
B:This is a test for Two zonal web instances should receive traffic only while their HTTP health checks succeed. The requirement here is instead demonstrated by rehearse failover and reconnect through the listener.
C:That verification addresses the different requirement: A zero-loss contractual SLA is proposed with asynchronous SQL geo-replication. It does not directly establish client access validates routing resilience.
