Microsoft AZ-305 Practice Test 40

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:

That observation pertains to a separate failure: Privileged operators modify evidentiary blobs before the legally required retention ends. Its cause is: The container lacks enforcement for write-once-read-many immutability requirements. It does not confirm the result of this design. The direct proof would be: Overwrite a test blob, list retained versions and recover the previous object content.

Question 391

During architecture troubleshooting, a team reports: The earlier object contents are unavailable after an application overwrite. Context: A research team mistakenly overwrites a blob used in an analytical result, needing prior blob content without rebuilding the data pipeline. Which underlying design mistake explains the observed behavior most precisely?

  1. Local redundancy did not distribute synchronous copies across availability zones.
  2. Soft delete retention was not enabled or its interval was too short.
  3. No blob versioning or recoverable earlier version policy was enabled.
  4. The container lacks enforcement for write-once-read-many immutability requirements.

Explanation

Correct Answer

C:

The incident is explained by: No blob versioning or recoverable earlier version policy was enabled. The reported symptom is: The earlier object contents are unavailable after an application overwrite. The corresponding design fix is: Enable blob versioning and appropriate soft-delete protection for eligible blobs.

Incorrect Answers

A:

The proposed diagnosis fits another scenario: Local redundancy did not distribute synchronous copies across availability zones. It would typically be reflected by: A single datacenter failure makes locally redundant blob data temporarily unavailable. The current evidence instead supports: No blob versioning or recoverable earlier version policy was enabled.

B:

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: The earlier object contents are unavailable after an application overwrite. The direct cause here is: No blob versioning or recoverable earlier version policy was enabled.

D:

The proposed diagnosis fits another scenario: The container lacks enforcement for write-once-read-many immutability requirements. It would typically be reflected by: Privileged operators modify evidentiary blobs before the legally required retention ends. The current evidence instead supports: No blob versioning or recoverable earlier version policy was enabled.

Question 392

The design change is: Enable blob versioning and appropriate soft-delete protection for eligible blobs. The original failure was: The earlier object contents are unavailable after an application overwrite. Which ongoing control best prevents recurrence of the same root cause?

  1. Check regional ZRS support and workload availability after storage configuration changes.
  2. Test blob recovery and review retention settings when datasets change risk tiers.
  3. Audit retention policy locks and legal hold changes with separation of duties.
  4. Audit version retention and cleanup cost together with lifecycle policies.

Explanation

Correct Answer

D:

This is an ongoing protection specific to the fault: Audit version retention and cleanup cost together with lifecycle policies. The recurrence risk is: No blob versioning or recoverable earlier version policy was enabled. It should be checked using: Overwrite a test blob, list retained versions and recover the previous object content.

Incorrect Answers

A:

This is a reasonable safeguard for a different fault: A single datacenter failure makes locally redundant blob data temporarily unavailable. That different mechanism is: Local redundancy did not distribute synchronous copies across availability zones. The original incident here instead arises from: No blob versioning or recoverable earlier version policy was enabled. The directly relevant safeguard is: Audit version retention and cleanup cost together with lifecycle policies.

B:

The proposed control focuses on: Soft delete retention was not enabled or its interval was too short. For the design in the question, recurrence comes from: No blob versioning or recoverable earlier version policy was enabled. A precise prevention step is: Audit version retention and cleanup cost together with lifecycle policies.

C:

That safeguard manages another risk: The container lacks enforcement for write-once-read-many immutability requirements. Its scenario is: Privileged operators modify evidentiary blobs before the legally required retention ends. The present recurring risk is: No blob versioning or recoverable earlier version policy was enabled. The proper ongoing control is: Audit version retention and cleanup cost together with lifecycle policies.

Question 393

A design workshop has this requirement: A public-storage design must prevent accidental deletion of a blob for one month even if a client application sends a Delete request. Operators currently observe: A developer's accidental deletion destroys the only live blob immediately. Select the ONE design remedy that best addresses the root cause.

  1. Choose Azure Blob Storage with suitable access tier and lifecycle rules rather than a relational database BLOB column.
  2. Enable blob versioning and appropriate soft-delete protection for eligible blobs.
  3. Configure supported blob soft delete with a sufficient retention interval and validate recoverability.
  4. Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region.

Explanation

Correct Answer

C:

The evidence (A developer's accidental deletion destroys the only live blob immediately.) identifies the following cause: Soft delete retention was not enabled or its interval was too short. The design that removes it is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. The acceptance check is: Delete a test blob and restore it during the permitted soft-delete interval.

Incorrect Answers

A:

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: Configure supported blob soft delete with a sufficient retention interval and validate recoverability.

B:

That design instead addresses another observed condition: The earlier object contents are unavailable after an application overwrite. Its technical cause is: No blob versioning or recoverable earlier version policy was enabled. The current workload exhibits: A developer's accidental deletion destroys the only live blob immediately. Its targeted remedy is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability.

D:

The option belongs to a different failure mechanism: Local redundancy did not distribute synchronous copies across availability zones. That situation exhibits: A single datacenter failure makes locally redundant blob data temporarily unavailable. For the stated case, the remedy is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability.

Question 394

The planned architecture is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. Workload context: A public-storage design must prevent accidental deletion of a blob for one month even if a client application sends a Delete request. Which acceptance test demonstrates that the required behavior works?

  1. Simulate zonal failure conditions and verify primary-region access remains available as designed.
  2. Overwrite a test blob, list retained versions and recover the previous object content.
  3. Delete a test blob and restore it during the permitted soft-delete interval.
  4. Upload a sample object and verify HTTP object retrieval, metadata and lifecycle behavior.

Explanation

Correct Answer

C:

The acceptance test is specific: Delete a test blob and restore it during the permitted soft-delete interval. Its purpose is to establish that the proposed architecture works: Configure supported blob soft delete with a sufficient retention interval and validate recoverability.

Incorrect Answers

A:

The alternative test targets: Select zone-redundant storage (ZRS) for supported blob workloads in a suitable region. The scenario's actual proposed remedy is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. Verify that one by: Delete a test blob and restore it during the permitted soft-delete interval.

B:

This check validates a different workload: Overwrite a test blob, list retained versions and recover the previous object content. Its associated design is: Enable blob versioning and appropriate soft-delete protection for eligible blobs. The required acceptance test here is: Delete a test blob and restore it during the permitted soft-delete interval.

D:

The scenario's actual proposed remedy is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. Verify that one by: Delete a test blob and restore it during the permitted soft-delete interval.

Question 395

The customer states: A public-storage design must prevent accidental deletion of a blob for one month even if a client application sends a Delete request. An incident reveals: A developer's accidental deletion destroys the only live blob immediately. What cause best accounts for this evidence?

  1. Soft delete retention was not enabled or its interval was too short.
  2. Local redundancy did not distribute synchronous copies across availability zones.
  3. No blob versioning or recoverable earlier version policy was enabled.
  4. Object storage's independent capacity and access tiers were not used for unstructured media.

Explanation

Correct Answer

A:

The recorded behavior follows from: Soft delete retention was not enabled or its interval was too short. The appropriate mitigation would be: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. Verify with: Delete a test blob and restore it during the permitted soft-delete interval.

Incorrect Answers

B:

This cause would explain a different symptom: A single datacenter failure makes locally redundant blob data temporarily unavailable. The mechanism for that event is: Local redundancy did not distribute synchronous copies across availability zones. Here the stated symptom is: 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.

C:

The proposed diagnosis fits another scenario: No blob versioning or recoverable earlier version policy was enabled. It would typically be reflected by: The earlier object contents are unavailable after an application overwrite. The current evidence instead supports: Soft delete retention was not enabled or its interval was too short.

The direct cause here is: Soft delete retention was not enabled or its interval was too short.

Question 396

Workload context: A public-storage design must prevent accidental deletion of a blob for one month even if a client application sends a Delete request. The implemented remedy is: Configure supported blob soft delete with a sufficient retention interval and validate recoverability. Which ongoing practice most specifically prevents recurrence of this failure: A developer's accidental deletion destroys the only live blob immediately.?

  1. Review blob lifecycle and access policies when data temperature changes.
  2. Audit version retention and cleanup cost together with lifecycle policies.
  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

C:

This is an ongoing protection specific to the fault: Test blob recovery and review retention settings when datasets change risk tiers. The recurrence risk is: Soft delete retention was not enabled or its interval was too short. It should be checked using: Delete a test blob and restore it during the permitted soft-delete interval.

Incorrect Answers

A:

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: Soft delete retention was not enabled or its interval was too short. A precise prevention step is: Test blob recovery and review retention settings when datasets change risk tiers.

B:

That safeguard manages another risk: No blob versioning or recoverable earlier version policy was enabled. Its scenario is: The earlier object contents are unavailable after an application overwrite. The present recurring risk is: Soft delete retention was not enabled or its interval was too short. The proper ongoing control is: Test blob recovery and review retention settings when datasets change risk tiers.

D:

For the design in the question, recurrence comes from: Soft delete retention was not enabled or its interval was too short. A precise prevention step is: Test blob recovery and review retention settings when datasets change risk tiers.

Question 397

A solution architect is reviewing a workload: A legal evidence container must prevent overwrites and deletions during a seven-year regulatory hold. The observed incident is: Privileged operators modify evidentiary blobs before the legally required retention ends. Which architecture choice most directly removes the identified weakness?

  1. Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.
  2. Configure supported blob soft delete with a sufficient retention interval and validate recoverability.
  3. Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.
  4. Enable blob versioning and appropriate soft-delete protection for eligible blobs.

Explanation

Correct Answer

C:

The targeted implementation is: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting. The problem is not generic resource availability: The container lacks enforcement for write-once-read-many immutability requirements. Verify the result by: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.

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: Privileged operators modify evidentiary blobs before the legally required retention ends. Its targeted remedy is: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

B:

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: The container lacks enforcement for write-once-read-many immutability requirements. Choose the corresponding action: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

D:

That design instead addresses another observed condition: The earlier object contents are unavailable after an application overwrite. Its technical cause is: No blob versioning or recoverable earlier version policy was enabled. The current workload exhibits: Privileged operators modify evidentiary blobs before the legally required retention ends. Its targeted remedy is: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

Question 398

An architect proposes this change: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting. The workload context is: A legal evidence container must prevent overwrites and deletions during a seven-year regulatory hold. Which evidence would most directly validate the change?

  1. Rehydrate a test archive blob and confirm retrieval follows the supported priority and completion behavior.
  2. Delete a test blob and restore it during the permitted soft-delete interval.
  3. Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.
  4. Overwrite a test blob, list retained versions and recover the previous object content.

Explanation

Correct Answer

C:

The decisive evidence is: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified. This measures the mechanism of the planned change, not an unrelated Azure service: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

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: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.

B:

Question 400

Consider this Azure design: A legal evidence container must prevent overwrites and deletions during a seven-year regulatory hold. To address the recurring incident (Privileged operators modify evidentiary blobs before the legally required retention ends.), select THREE complementary actions: the direct design remedy, a direct acceptance test, and one ongoing protective control. Do not count a remedy for another workload as equivalent.

  1. Test blob recovery and review retention settings when datasets change risk tiers.
  2. Audit retention policy locks and legal hold changes with separation of duties.
  3. Overwrite a test blob, list retained versions and recover the previous object content.
  4. Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.
  5. Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.
  6. Apply an appropriate Blob archive access tier for eligible blob objects, accounting for rehydration time.

Explanation

Correct Answers

B:

This is an ongoing protection specific to the fault: Audit retention policy locks and legal hold changes with separation of duties. The recurrence risk is: The container lacks enforcement for write-once-read-many immutability requirements. It should be checked using: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.

D:

This option addresses the actual design defect: The container lacks enforcement for write-once-read-many immutability requirements.

Confirm the outcome with: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified.

E:

The acceptance test is specific: Attempt a delete and overwrite during retention and confirm that protected objects cannot be modified. Its purpose is to establish that the proposed architecture works: Apply an appropriate Azure Blob immutability policy with a compliant time-based retention or legal hold setting.

Incorrect Answers

A:

That safeguard manages another risk: Soft delete retention was not enabled or its interval was too short. Its scenario is: A developer's accidental deletion destroys the only live blob immediately. The present recurring risk is: The container lacks enforcement for write-once-read-many immutability requirements.
