Question 490

Regulators require a yearly Azure SQL backup for ten years. Which Azure architecture choice best meets this requirement?

  1. Configure supported Azure SQL long-term retention backups.
  2. Use only geo-replicated live databases as the sole immutable recovery source.
  3. Depend on default short-term backups for ten-year compliance.
  4. Enable zone redundancy and expect it to undo a committed DROP TABLE.

Explanation

Correct Answer

A:

LTR preserves selected backups beyond short-term PITR windows.

Incorrect Answers

B:

Live replicas may contain the same erroneous write. In the present requirement, regulators require a yearly Azure SQL backup for ten years. The needed design instead works because lTR preserves selected backups beyond short-term PITR windows.

C:

Standard PITR retention does not guarantee ten years of recovery points. This proposal contradicts the stated architecture constraint.

D:

High availability replicates deletions instead of preserving prior logical state. In the present requirement, regulators require a yearly Azure SQL backup for ten years. The needed design instead works because lTR preserves selected backups beyond short-term PITR windows.

Question 491

An architecture proposal for sql backup point in time and ltr relies on the following approach: Depend on default short-term backups for ten-year compliance. Which specific failure or mismatch should the design reviewer identify?

  1. A single recent recovery point cannot satisfy historic retention.
  2. High availability replicates deletions instead of preserving prior logical state.
  3. Standard PITR retention does not guarantee ten years of recovery points.
  4. Live replicas may contain the same erroneous write.

Explanation

Correct Answer

C:

Depend on default short-term backups for ten-year compliance. Standard PITR retention does not guarantee ten years of recovery points.

Incorrect Answers

A:

This concern applies to Keep only the newest daily backup and call it long-term archive. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because standard PITR retention does not guarantee ten years of recovery points.

B:

That assessment refers to the separate proposal 'Enable zone redundancy and expect it to undo a committed DROP TABLE.' not to the recommendation under review. Here, Standard PITR retention does not guarantee ten years of recovery points.

D:

That assessment refers to the separate proposal 'Use only geo-replicated live databases as the sole immutable recovery source.' not to the recommendation under review. Here, Standard PITR retention does not guarantee ten years of recovery points.

Question 492

Acceptance testing must establish the following operational result: Historical restore points establish compliance evidence. Which verification action most directly establishes that outcome?

  1. Inject a test bad update and restore from a pre-change backup.
  2. Inspect yearly LTR points and retention expiration dates.
  3. List points from the requested years in the vault.
  4. Restore to just before the drop and query representative table rows.

Explanation

Correct Answer

B:

Historical restore points establish compliance evidence.

Incorrect Answers

A:

That verification addresses the different requirement: An operations team expects active geo-replication to protect against a malicious data update. It does not directly establish historical restore points establish compliance evidence.

C:

This is a test for An audit demands monthly recovery points retained for several years. The requirement here is instead demonstrated by inspect yearly LTR points and retention expiration dates.

D:

That verification addresses the different requirement: A developer drops an important table and notices the error two hours later. It does not directly establish historical restore points establish compliance evidence.

Question 493

An operations team expects active geo-replication to protect against a malicious data update. Which Azure architecture choice best meets this requirement?

  1. Add point-in-time backup and recovery to the geo-replication design.
  2. Enable zone redundancy and expect it to undo a committed DROP TABLE.
  3. Depend on default short-term backups for ten-year compliance.
  4. Use only geo-replicated live databases as the sole immutable recovery source.

Explanation

Correct Answer

A:

Data corruption and valid malicious changes can replicate to secondary databases.

Incorrect Answers

B:

High availability replicates deletions instead of preserving prior logical state. In the present requirement, an operations team expects active geo-replication to protect against a malicious data update. The needed design instead works because data corruption and valid malicious changes can replicate to secondary databases.

C:

Standard PITR retention does not guarantee ten years of recovery points. In the present requirement, an operations team expects active geo-replication to protect against a malicious data update. The needed design instead works because data corruption and valid malicious changes can replicate to secondary databases.

D:

Question 494

An architecture proposal for sql backup point in time and ltr relies on the following approach: Use only geo-replicated live databases as the sole immutable recovery source. Which specific failure or mismatch should the design reviewer identify?

  1. High availability replicates deletions instead of preserving prior logical state.
  2. Standard PITR retention does not guarantee ten years of recovery points.
  3. Live replicas may contain the same erroneous write.
  4. Default resolution can pick one winner and may not preserve all conflicts.

Explanation

Correct Answer

C:

Use only geo-replicated live databases as the sole immutable recovery source. Live replicas may contain the same erroneous write.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Enable zone redundancy and expect it to undo a committed DROP TABLE.' not to the recommendation under review. Here, Live replicas may contain the same erroneous write.

B:

That assessment refers to the separate proposal 'Depend on default short-term backups for ten-year compliance.' not to the recommendation under review. Here, Live replicas may contain the same erroneous write.

D:

This concern applies to Assume multi-write means every conflicting version is retained automatically forever. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because live replicas may contain the same erroneous write.

Question 495

Acceptance testing must establish the following operational result: Verified old state demonstrates protection from logical corruption. Which verification action most directly establishes that outcome?

  1. Restore to just before the drop and query representative table rows.
  2. Submit controlled competing updates and inspect resolved document state.
  3. Inspect yearly LTR points and retention expiration dates.
  4. Inject a test bad update and restore from a pre-change backup.

Explanation

Correct Answer

D:

Verified old state demonstrates protection from logical corruption.

Incorrect Answers

A:

That verification addresses the different requirement: A developer drops an important table and notices the error two hours later. It does not directly establish verified old state demonstrates protection from logical corruption.

B:

This is a test for A globally writable Cosmos database needs deterministic conflict behavior during multi-region writes. The requirement here is instead demonstrated by inject a test bad update and restore from a pre-change backup.

C:

That verification addresses the different requirement: Regulators require a yearly Azure SQL backup for ten years. It does not directly establish verified old state demonstrates protection from logical corruption.

Question 496

A mission-critical Cosmos DB account needs read availability from multiple regions. Which Azure architecture choice best meets this requirement?

  1. Treat geo-replication as an immutable historic container snapshot.
  2. Put all readers and writes into one regional endpoint without failover design.
  3. Assume multi-write means every conflicting version is retained automatically forever.
  4. Configure appropriate Cosmos DB regional distribution and consistency policy.

Explanation

Correct Answer

D:

Multi-region replicas can provide regional read locality and resiliency.

Incorrect Answers

A:

Deletes may propagate across replicated live state. In the present requirement, a mission-critical Cosmos DB account needs read availability from multiple regions. The needed design instead works because multi-region replicas can provide regional read locality and resiliency.

B:

Single-region concentration exposes requests to complete regional outage. This proposal contradicts the stated architecture constraint.

C:

Default resolution can pick one winner and may not preserve all conflicts. In the present requirement, a mission-critical Cosmos DB account needs read availability from multiple regions. The needed design instead works because multi-region replicas can provide regional read locality and resiliency.

  2. Simulate a supported regional read routing test.
  3. Restore a test dataset after controlled logical deletion using configured recovery mode.
  4. Submit controlled competing updates and inspect resolved document state.

Explanation

Correct Answer

B:
