Question 370

The planned architecture is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. Workload context: A storage account must survive a single availability-zone outage while data continues serving reads and writes within the primary region. Which acceptance test demonstrates that the required behavior works?

  1. Verify redundancy setting, secondary-region replication status and a documented storage failover test.
  2. Simulate zonal failure conditions and verify primary-region access remains available as designed.
  3. Delete a test blob and restore it during the permitted soft-delete interval.
  4. Read a test object from the secondary endpoint and confirm writes remain limited to the primary.

Explanation

Correct Answer

B:

This observation directly verifies the intended design: Simulate zonal failure conditions and verify primary-region access remains available as designed. The architecture being tested is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. The original symptom was: A single datacenter failure makes locally redundant blob data temporarily unavailable.

Incorrect Answers

A:

The alternative test targets: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations. The scenario's actual proposed remedy is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. Verify that one by: Simulate zonal failure conditions and verify primary-region access remains available as designed.

C:

That observation pertains to a separate failure: A developer's accidental deletion destroys the only live blob immediately. Its cause is: Soft delete retention was not enabled or its interval was too short. It does not confirm the result of this design. The direct proof would be: Simulate zonal failure conditions and verify primary-region access remains available as designed.

D:

The alternative test targets: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint. The scenario's actual proposed remedy is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. Verify that one by: Simulate zonal failure conditions and verify primary-region access remains available as designed.

Question 371

The customer states: A storage account must survive a single availability-zone outage while data continues serving reads and writes within the primary region. An incident reveals: A single datacenter failure makes locally redundant blob data temporarily unavailable. What cause best accounts for this evidence?

  1. ZRS was selected without the needed geographical disaster-recovery replica.
  2. Geo-redundancy alone does not expose a read-enabled secondary endpoint.
  3. Local redundancy did not distribute synchronous copies across availability zones.
  4. Soft delete retention was not enabled or its interval was too short.

Explanation

Correct Answer

C:

This is the failure mechanism rather than an incidental symptom: Local redundancy did not distribute synchronous copies across availability zones. It accounts for: A single datacenter failure makes locally redundant blob data temporarily unavailable. The architectural repair is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region.

Incorrect Answers

A:

The alternative weakness is: ZRS was selected without the needed geographical disaster-recovery replica. Its associated failure is: Zone-resilient storage lacks any copy outside the primary region. Neither explains the present observation: A single datacenter failure makes locally redundant blob data temporarily unavailable. The direct cause here is: Local redundancy did not distribute synchronous copies across availability zones.

B:

This cause would explain a different symptom: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption. The mechanism for that event is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. Here the stated symptom is: A single datacenter failure makes locally redundant blob data temporarily unavailable. Its cause is: Local redundancy did not distribute synchronous copies across availability zones.

D:

The alternative weakness is: Soft delete retention was not enabled or its interval was too short. Its associated failure is: A developer's accidental deletion destroys the only live blob immediately. Neither explains the present observation: A single datacenter failure makes locally redundant blob data temporarily unavailable. The direct cause here is: Local redundancy did not distribute synchronous copies across availability zones.

Question 372

Workload context: A storage account must survive a single availability-zone outage while data continues serving reads and writes within the primary region. The implemented remedy is: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. Which ongoing practice most specifically prevents recurrence of this failure: A single datacenter failure makes locally redundant blob data temporarily unavailable.?

  1. Monitor secondary read availability and potential lag before routing critical reports.
  2. Review regional failover RPO assumptions because secondary replication is asynchronous.
  3. Test blob recovery and review retention settings when datasets change risk tiers.
  4. Check regional ZRS support and workload availability after storage configuration changes.

Explanation

Correct Answer

D:

The key follow-up control is: Check regional ZRS support and workload availability after storage configuration changes. It avoids recurrence of the scenario in which: A single datacenter failure makes locally redundant blob data temporarily unavailable. It addresses: Local redundancy did not distribute synchronous copies across availability zones.

Incorrect Answers

A:

The proposed control focuses on: Geo-redundancy alone does not expose a read-enabled secondary endpoint. For the design in the question, recurrence comes from: Local redundancy did not distribute synchronous copies across availability zones. A precise prevention step is: Check regional ZRS support and workload availability after storage configuration changes.

B:

That safeguard manages another risk: ZRS was selected without the needed geographical disaster-recovery replica. Its scenario is: Zone-resilient storage lacks any copy outside the primary region. The present recurring risk is: Local redundancy did not distribute synchronous copies across availability zones. The proper ongoing control is: Check regional ZRS support and workload availability after storage configuration changes.

C:

This is a reasonable safeguard for a different fault: A developer's accidental deletion destroys the only live blob immediately. That different mechanism is: Soft delete retention was not enabled or its interval was too short. The original incident here instead arises from: Local redundancy did not distribute synchronous copies across availability zones. The directly relevant safeguard is: Check regional ZRS support and workload availability after storage configuration changes.

Question 373

A solution architect is reviewing a workload: A critical document archive needs zone fault tolerance in its main region plus an asynchronous copy in a geographically separate region. The observed incident is: Zone-resilient storage lacks any copy outside the primary region. Which architecture choice most directly removes the identified weakness?

  1. Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint.
  2. Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region.
  3. Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.
  4. Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.

Explanation

Correct Answer

D:

This option addresses the actual design defect: ZRS was selected without the needed geographical disaster-recovery replica. The correction is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations. Confirm the outcome with: Verify redundancy setting, secondary-region replication status and a documented storage failover test.

Incorrect Answers

A:

That design instead addresses another observed condition: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption. Its technical cause is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. The current workload exhibits: Zone-resilient storage lacks any copy outside the primary region. Its targeted remedy is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.

B:

This choice mitigates an alternative scenario, where: A single datacenter failure makes locally redundant blob data temporarily unavailable. The underlying issue there is: Local redundancy did not distribute synchronous copies across availability zones. Here the root issue is: ZRS was selected without the needed geographical disaster-recovery replica. Choose the corresponding action: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.

C:

The option belongs to a different failure mechanism: Archive access tier requires rehydration and is not an online hot object endpoint. That situation exhibits: Audit retrieval fails when an app expects instant downloads from archived objects. For the stated case, the remedy is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.

Question 374

An architect proposes this change: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations. The workload context is: A critical document archive needs zone fault tolerance in its main region plus an asynchronous copy in a geographically separate region. Which evidence would most directly validate the change?

  1. Verify redundancy setting, secondary-region replication status and a documented storage failover test.
  2. Simulate zonal failure conditions and verify primary-region access remains available as designed.
  3. Read a test object from the secondary endpoint and confirm writes remain limited to the primary.
  4. Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.

Explanation

Correct Answer

A:

This observation directly verifies the intended design: Verify redundancy setting, secondary-region replication status and a documented storage failover test. The architecture being tested is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations. The original symptom was: Zone-resilient storage lacks any copy outside the primary region.

Incorrect Answers

B:

D:

This check validates a different workload: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior. Its associated design is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. The required acceptance test here is: Verify redundancy setting, secondary-region replication status and a documented storage failover test.

Question 375

During architecture troubleshooting, a team reports: Zone-resilient storage lacks any copy outside the primary region. Context: A critical document archive needs zone fault tolerance in its main region plus an asynchronous copy in a geographically separate region. Which underlying design mistake explains the observed behavior most precisely?

  1. ZRS was selected without the needed geographical disaster-recovery replica.
  2. Archive access tier requires rehydration and is not an online hot object endpoint.
  3. Geo-redundancy alone does not expose a read-enabled secondary endpoint.
  4. Local redundancy did not distribute synchronous copies across availability zones.

Explanation

Correct Answer

A:

The incident is explained by: ZRS was selected without the needed geographical disaster-recovery replica. The reported symptom is: Zone-resilient storage lacks any copy outside the primary region. The corresponding design fix is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.

Incorrect Answers

B:

The proposed diagnosis fits another scenario: Archive access tier requires rehydration and is not an online hot object endpoint. It would typically be reflected by: Audit retrieval fails when an app expects instant downloads from archived objects. The current evidence instead supports: ZRS was selected without the needed geographical disaster-recovery replica.

C:

The alternative weakness is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. Its associated failure is: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption. Neither explains the present observation: Zone-resilient storage lacks any copy outside the primary region. The direct cause here is: ZRS was selected without the needed geographical disaster-recovery replica.

D:

The mechanism for that event is: Local redundancy did not distribute synchronous copies across availability zones. Here the stated symptom is: Zone-resilient storage lacks any copy outside the primary region. Its cause is: ZRS was selected without the needed geographical disaster-recovery replica.

Question 376

The design change is: Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations. The original failure was: Zone-resilient storage lacks any copy outside the primary region. Which ongoing control best prevents recurrence of the same root cause?

  1. Monitor secondary read availability and potential lag before routing critical reports.
  2. Review regional failover RPO assumptions because secondary replication is asynchronous.
  3. Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.
  4. Check regional ZRS support and workload availability after storage configuration changes.

Explanation

Correct Answer

B:

This is an ongoing protection specific to the fault: Review regional failover RPO assumptions because secondary replication is asynchronous. The recurrence risk is: ZRS was selected without the needed geographical disaster-recovery replica. It should be checked using: Verify redundancy setting, secondary-region replication status and a documented storage failover test.

Incorrect Answers

A:

That safeguard manages another risk: Geo-redundancy alone does not expose a read-enabled secondary endpoint. Its scenario is: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption. The present recurring risk is: ZRS was selected without the needed geographical disaster-recovery replica. The proper ongoing control is: Review regional failover RPO assumptions because secondary replication is asynchronous.

C:

Question 377

A design workshop has this requirement: A read-only global reporting service must access a secondary-region blob replica even before an official account failover. Operators currently observe: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption. Select the ONE design remedy that best addresses the root cause.

  1. Configure supported Azure Cosmos DB multi-region writes with an explicit conflict resolution strategy and appropriate consistency.
  2. Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint.
  3. Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.
  4. Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region.

Explanation

Correct Answer

B:

The targeted implementation is: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint. The problem is not generic resource availability: Geo-redundancy alone does not expose a read-enabled secondary endpoint. Verify the result by: Read a test object from the secondary endpoint and confirm writes remain limited to the primary.

Incorrect Answers

A:

This choice mitigates an alternative scenario, where: An overseas region must send writes to a remote single-write region despite local performance targets. The underlying issue there is: Multi-region write capability and conflict resolution were not designed for the active-active requirement. Here the root issue is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. Choose the corresponding action: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint.

C:

That design instead addresses another observed condition: Zone-resilient storage lacks any copy outside the primary region. Its technical cause is: ZRS was selected without the needed geographical disaster-recovery replica.

Question 378

The planned architecture is: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint. Workload context: A read-only global reporting service must access a secondary-region blob replica even before an official account failover. Which acceptance test demonstrates that the required behavior works?

  1. Verify redundancy setting, secondary-region replication status and a documented storage failover test.
  2. Read a test object from the secondary endpoint and confirm writes remain limited to the primary.
  3. Simulate zonal failure conditions and verify primary-region access remains available as designed.
  4. Write from two configured regions and verify cross-region propagation and conflict outcomes under controlled concurrent updates.

Explanation

Correct Answer

B:

The decisive evidence is: Read a test object from the secondary endpoint and confirm writes remain limited to the primary. This measures the mechanism of the planned change, not an unrelated Azure service: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint.
