Microsoft AZ-305 Practice Test 39

Question 380

Workload context: A read-only global reporting service must access a secondary-region blob replica even before an official account failover. The implemented remedy is: Use read-access geo-redundant storage (RA-GRS or RA-GZRS) when supported, with app logic for the secondary endpoint. Which ongoing practice most specifically prevents recurrence of this failure: Secondary-region clients cannot read replicas from a standard GRS account during primary-region disruption.?

  1. Monitor secondary read availability and potential lag before routing critical reports.
  2. Review regional failover RPO assumptions because secondary replication is asynchronous.
  3. Check regional ZRS support and workload availability after storage configuration changes.
  4. Monitor replication and conflict metrics, documenting bounded consistency tradeoffs.

Explanation

Correct Answer

A:

This is an ongoing protection specific to the fault: Monitor secondary read availability and potential lag before routing critical reports. The recurrence risk is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. It should be checked using: Read a test object from the secondary endpoint and confirm writes remain limited to the primary.

Incorrect Answers

B:

The proposed control focuses on: ZRS was selected without the needed geographical disaster-recovery replica. For the design in the question, recurrence comes from: Geo-redundancy alone does not expose a read-enabled secondary endpoint. A precise prevention step is: Monitor secondary read availability and potential lag before routing critical reports.

C:

That safeguard manages another risk: Local redundancy did not distribute synchronous copies across availability zones. Its scenario is: A single datacenter failure makes locally redundant blob data temporarily unavailable. The present recurring risk is: Geo-redundancy alone does not expose a read-enabled secondary endpoint. The proper ongoing control is: Monitor secondary read availability and potential lag before routing critical reports.

D:

This is a reasonable safeguard for a different fault: An overseas region must send writes to a remote single-write region despite local performance targets. That different mechanism is: Multi-region write capability and conflict resolution were not designed for the active-active requirement. The original incident here instead arises from: Geo-redundancy alone does not expose a read-enabled secondary endpoint. The directly relevant safeguard is: Monitor secondary read availability and potential lag before routing critical reports.

Question 381

A solution architect is reviewing a workload: An archive stores evidence that must be rarely accessed, but files must be retrieved in hours rather than instantly and storage cost should be minimized. The observed incident is: Audit retrieval fails when an app expects instant downloads from archived objects. Which architecture choice most directly removes the identified weakness?

  1. Select geo-zone-redundant storage (GZRS) for eligible blob accounts and define regional failover expectations.
  2. Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.
  3. Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.
  4. Choose Azure Blob Storage with suitable access tier and lifecycle rules rather than a relational database BLOB column.

Explanation

Correct Answer

B:

This option addresses the actual design defect: Archive access tier requires rehydration and is not an online hot object endpoint. The correction is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. Confirm the outcome with: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.

Incorrect Answers

A:

The option belongs to a different failure mechanism: ZRS was selected without the needed geographical disaster-recovery replica. That situation exhibits: Zone-resilient storage lacks any copy outside the primary region. For the stated case, the remedy is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

C:

This choice mitigates an alternative scenario, where: Old data remains in hot tier indefinitely despite rarely being accessed. The underlying issue there is: No automated lifecycle rules govern predictable age-based storage transitions. Here the root issue is: Archive access tier requires rehydration and is not an online hot object endpoint. Choose the corresponding action: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

D:

The option belongs to a different failure mechanism: Object storage's independent capacity and access tiers were not used for unstructured media. That situation exhibits: The application stores huge media files in the transactional SQL database and exhausts database capacity. For the stated case, the remedy is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

Question 382

An architect proposes this change: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. The workload context is: An archive stores evidence that must be rarely accessed, but files must be retrieved in hours rather than instantly and storage cost should be minimized. Which evidence would most directly validate the change?

  1. Create a test blob and inspect lifecycle action results and object tier transitions.
  2. Upload a sample object and verify HTTP object retrieval, metadata and lifecycle behavior.
  3. Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.
  4. Verify redundancy setting, secondary-region replication status and a documented storage failover test.

Explanation

Correct Answer

C:

The acceptance test is specific: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior. Its purpose is to establish that the proposed architecture works: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

Incorrect Answers

A:

The alternative test targets: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. The scenario's actual proposed remedy is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. Verify that one by: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.

B:

This check validates a different workload: Upload a sample object and verify HTTP object retrieval, metadata and lifecycle behavior. Its associated design is: Choose Azure Blob Storage with suitable access tier and lifecycle rules rather than a relational database BLOB column. The required acceptance test here is: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.

D:

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: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. Verify that one by: Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.

Question 383

During architecture troubleshooting, a team reports: Audit retrieval fails when an app expects instant downloads from archived objects. Context: An archive stores evidence that must be rarely accessed, but files must be retrieved in hours rather than instantly and storage cost should be minimized. Which underlying design mistake explains the observed behavior most precisely?

  1. ZRS was selected without the needed geographical disaster-recovery replica.
  2. No automated lifecycle rules govern predictable age-based storage transitions.
  3. Archive access tier requires rehydration and is not an online hot object endpoint.
  4. Object storage's independent capacity and access tiers were not used for unstructured media.

Explanation

Correct Answer

C:

This is the failure mechanism rather than an incidental symptom: Archive access tier requires rehydration and is not an online hot object endpoint. It accounts for: Audit retrieval fails when an app expects instant downloads from archived objects. The architectural repair is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

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: Audit retrieval fails when an app expects instant downloads from archived objects. The direct cause here is: Archive access tier requires rehydration and is not an online hot object endpoint.

B:

This cause would explain a different symptom: Old data remains in hot tier indefinitely despite rarely being accessed. The mechanism for that event is: No automated lifecycle rules govern predictable age-based storage transitions. Here the stated symptom is: Audit retrieval fails when an app expects instant downloads from archived objects. Its cause is: Archive access tier requires rehydration and is not an online hot object endpoint.

D:

The alternative weakness is: Object storage's independent capacity and access tiers were not used for unstructured media. Its associated failure is: The application stores huge media files in the transactional SQL database and exhausts database capacity. Neither explains the present observation: Audit retrieval fails when an app expects instant downloads from archived objects. The direct cause here is: Archive access tier requires rehydration and is not an online hot object endpoint.

Question 384

The design change is: Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time. The original failure was: Audit retrieval fails when an app expects instant downloads from archived objects. Which ongoing control best prevents recurrence of the same root cause?

  1. Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.
  2. Review lifecycle rules when retention, tier pricing or blob tags change.
  3. Review regional failover RPO assumptions because secondary replication is asynchronous.
  4. Review blob lifecycle and access policies when data temperature changes.

Explanation

Correct Answer

A:

The key follow-up control is: Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage. It avoids recurrence of the scenario in which: Audit retrieval fails when an app expects instant downloads from archived objects. It addresses: Archive access tier requires rehydration and is not an online hot object endpoint.

Incorrect Answers

B:

That safeguard manages another risk: No automated lifecycle rules govern predictable age-based storage transitions. Its scenario is: Old data remains in hot tier indefinitely despite rarely being accessed. The present recurring risk is: Archive access tier requires rehydration and is not an online hot object endpoint. The proper ongoing control is: Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.

C:

This is a reasonable safeguard for a different fault: Zone-resilient storage lacks any copy outside the primary region. That different mechanism is: ZRS was selected without the needed geographical disaster-recovery replica. The original incident here instead arises from: Archive access tier requires rehydration and is not an online hot object endpoint. The directly relevant safeguard is: Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.

D:

The proposed control focuses on: Object storage's independent capacity and access tiers were not used for unstructured media. For the design in the question, recurrence comes from: Archive access tier requires rehydration and is not an online hot object endpoint. A precise prevention step is: Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.

Question 385

A design workshop has this requirement: A telemetry archive has predictable aging, with objects hot for 30 days then cool for six months. Operators currently observe: Old data remains in hot tier indefinitely despite rarely being accessed. Select the ONE design remedy that best addresses the root cause.

  1. Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.
  2. Choose Azure Blob Storage with suitable access tier and lifecycle rules rather than a relational database BLOB column.
  3. Redesign the logical partition key or introduce an appropriate synthetic/hierarchical key strategy to distribute hot requests.
  4. Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.

Explanation

Correct Answer

D:

This option addresses the actual design defect: No automated lifecycle rules govern predictable age-based storage transitions. The correction is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. Confirm the outcome with: Create a test blob and inspect lifecycle action results and object tier transitions.

Incorrect Answers

A:

That design instead addresses another observed condition: Audit retrieval fails when an app expects instant downloads from archived objects. Its technical cause is: Archive access tier requires rehydration and is not an online hot object endpoint. The current workload exhibits: Old data remains in hot tier indefinitely despite rarely being accessed. Its targeted remedy is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.

B:

This choice mitigates an alternative scenario, where: The application stores huge media files in the transactional SQL database and exhausts database capacity. The underlying issue there is: Object storage's independent capacity and access tiers were not used for unstructured media. Here the root issue is: No automated lifecycle rules govern predictable age-based storage transitions. Choose the corresponding action: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.

C:

The option belongs to a different failure mechanism: The partition key concentrates high-throughput tenant traffic into a hot logical partition. That situation exhibits: One logical partition gets 429 throttles despite plenty of total provisioned RU/s. For the stated case, the remedy is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.

Question 386

The planned architecture is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. Workload context: A telemetry archive has predictable aging, with objects hot for 30 days then cool for six months. Which acceptance test demonstrates that the required behavior works?

  1. Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.
  2. Upload a sample object and verify HTTP object retrieval, metadata and lifecycle behavior.
  3. Compare request-unit throttling and logical partition distribution before and after the key design.
  4. Create a test blob and inspect lifecycle action results and object tier transitions.

Explanation

Correct Answer

D:

This observation directly verifies the intended design: Create a test blob and inspect lifecycle action results and object tier transitions. The architecture being tested is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. The original symptom was: Old data remains in hot tier indefinitely despite rarely being accessed.

Incorrect Answers

A:

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: Create a test blob and inspect lifecycle action results and object tier transitions.

B:

That observation pertains to a separate failure: The application stores huge media files in the transactional SQL database and exhausts database capacity. Its cause is: Object storage's independent capacity and access tiers were not used for unstructured media. It does not confirm the result of this design. The direct proof would be: Create a test blob and inspect lifecycle action results and object tier transitions.

C:

The alternative test targets: Redesign the logical partition key or introduce an appropriate synthetic/hierarchical key strategy to distribute hot requests. The scenario's actual proposed remedy is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. Verify that one by: Create a test blob and inspect lifecycle action results and object tier transitions.

Question 387

The customer states: A telemetry archive has predictable aging, with objects hot for 30 days then cool for six months. An incident reveals: Old data remains in hot tier indefinitely despite rarely being accessed. What cause best accounts for this evidence?

  1. The partition key concentrates high-throughput tenant traffic into a hot logical partition.
  2. Archive access tier requires rehydration and is not an online hot object endpoint.
  3. Object storage's independent capacity and access tiers were not used for unstructured media.
  4. No automated lifecycle rules govern predictable age-based storage transitions.

Explanation

Correct Answer

D:

The incident is explained by: No automated lifecycle rules govern predictable age-based storage transitions. The reported symptom is: Old data remains in hot tier indefinitely despite rarely being accessed. The corresponding design fix is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions.

Incorrect Answers

A:

This cause would explain a different symptom: One logical partition gets 429 throttles despite plenty of total provisioned RU/s. The mechanism for that event is: The partition key concentrates high-throughput tenant traffic into a hot logical partition. Here the stated symptom is: Old data remains in hot tier indefinitely despite rarely being accessed. Its cause is: No automated lifecycle rules govern predictable age-based storage transitions.

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: No automated lifecycle rules govern predictable age-based storage transitions.

C:

The alternative weakness is: Object storage's independent capacity and access tiers were not used for unstructured media. Its associated failure is: The application stores huge media files in the transactional SQL database and exhausts database capacity. Neither explains the present observation: Old data remains in hot tier indefinitely despite rarely being accessed. The direct cause here is: No automated lifecycle rules govern predictable age-based storage transitions.

Question 388

Workload context: A telemetry archive has predictable aging, with objects hot for 30 days then cool for six months. The implemented remedy is: Define Blob lifecycle management rules to move blobs between supported access tiers by age or last access conditions. Which ongoing practice most specifically prevents recurrence of this failure: Old data remains in hot tier indefinitely despite rarely being accessed.?

  1. Review blob lifecycle and access policies when data temperature changes.
  2. Review retrieval SLAs, early deletion charges and redundancy compatibility for archive storage.
  3. Review top partition keys and request charge distribution as tenant traffic patterns change.
  4. Review lifecycle rules when retention, tier pricing or blob tags change.

Explanation

Correct Answer

D:

The preventive control is: Review lifecycle rules when retention, tier pricing or blob tags change. It targets the earlier cause: No automated lifecycle rules govern predictable age-based storage transitions. Confirm ongoing effectiveness by: Create a test blob and inspect lifecycle action results and object tier transitions.

Incorrect Answers

A:

That safeguard manages another risk: Object storage's independent capacity and access tiers were not used for unstructured media. Its scenario is: The application stores huge media files in the transactional SQL database and exhausts database capacity. The present recurring risk is: No automated lifecycle rules govern predictable age-based storage transitions. The proper ongoing control is: Review lifecycle rules when retention, tier pricing or blob tags change.

B:

This is a reasonable safeguard for a different fault: Audit retrieval fails when an app expects instant downloads from archived objects. That different mechanism is: Archive access tier requires rehydration and is not an online hot object endpoint. The original incident here instead arises from: No automated lifecycle rules govern predictable age-based storage transitions.

For the design in the question, recurrence comes from: No automated lifecycle rules govern predictable age-based storage transitions. A precise prevention step is: Review lifecycle rules when retention, tier pricing or blob tags change.

Question 389

A solution architect is reviewing a workload: A research team mistakenly overwrites a blob used in an analytical result, needing prior blob content without rebuilding the data pipeline. The observed incident is: The earlier object contents are unavailable after an application overwrite. Which architecture choice most directly removes the identified weakness?

  1. Configure supported blob soft delete with a sufficient retention interval and validate recoverability.
  2. Enable blob versioning and appropriate soft-delete protection for eligible blobs.
  3. Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region.
  4. Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

Explanation

Correct Answer

B:

The targeted implementation is: Enable blob versioning and appropriate soft-delete protection for eligible blobs. The problem is not generic resource availability: No blob versioning or recoverable earlier version policy was enabled. Verify the result by: Overwrite a test blob, list retained versions and recover the previous object content.

Incorrect Answers

A:

This choice mitigates an alternative scenario, where: A developer's accidental deletion destroys the only live blob immediately. The underlying issue there is: Soft delete retention was not enabled or its interval was too short. Here the root issue is: No blob versioning or recoverable earlier version policy was enabled. Choose the corresponding action: Enable blob versioning and appropriate soft-delete protection for eligible blobs.

C:

That design instead addresses another observed condition: A single datacenter failure makes locally redundant blob data temporarily unavailable. Its technical cause is: Local redundancy did not distribute synchronous copies across availability zones. The current workload exhibits: The earlier object contents are unavailable after an application overwrite. Its targeted remedy is: Enable blob versioning and appropriate soft-delete protection for eligible blobs.

D:

This choice mitigates an alternative scenario, where: Privileged operators modify evidentiary blobs before the legally required retention ends. The underlying issue there is: The container lacks enforcement for write-once-read-many immutability requirements. Here the root issue is: No blob versioning or recoverable earlier version policy was enabled. Choose the corresponding action: Enable blob versioning and appropriate soft-delete protection for eligible blobs.

Question 390

An architect proposes this change: Enable blob versioning and appropriate soft-delete protection for eligible blobs. The workload context is: A research team mistakenly overwrites a blob used in an analytical result, needing prior blob content without rebuilding the data pipeline. Which evidence would most directly validate the change?

  1. Overwrite a test blob, list retained versions and recover the previous object content.
  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. Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.

Explanation

Correct Answer

A:

The acceptance test is specific: Overwrite a test blob, list retained versions and recover the previous object content. Its purpose is to establish that the proposed architecture works: Enable blob versioning and appropriate soft-delete protection for eligible blobs.

Incorrect Answers

B:

The alternative test targets: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. The scenario's actual proposed remedy is: Enable blob versioning and appropriate soft-delete protection for eligible blobs. Verify that one by: Overwrite a test blob, list retained versions and recover the previous object content.

C:

This check validates a different workload: Delete a test blob and restore it during the permitted soft-delete interval. Its associated design is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. The required acceptance test here is: Overwrite a test blob, list retained versions and recover the previous object content.

D:
