Question 480

Acceptance testing must establish the following operational result: End-to-end app testing demonstrates realistic hybrid DR. Which verification action most directly establishes that outcome?

  1. Prove reverse replication catches up before an approved failback.
  2. Rehearse workload recovery in Azure with network and DNS adjustments.
  3. Submit controlled competing updates and inspect resolved document state.
  4. Compare test-failover timing against each tier's RTO and RPO.

Explanation

Correct Answer

B:

End-to-end app testing demonstrates realistic hybrid DR.

Incorrect Answers

A:

That verification addresses the different requirement: A failed on-premises site has recovered and workloads need a controlled return to primary. It does not directly establish end-to-end app testing demonstrates realistic hybrid DR.

C:

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 rehearse workload recovery in Azure with network and DNS adjustments.

D:

That verification addresses the different requirement: A VMware estate has many VMs with different recovery priorities. It does not directly establish end-to-end app testing demonstrates realistic hybrid DR.

Question 481

A VMware estate has many VMs with different recovery priorities. Which Azure architecture choice best meets this requirement?

  1. Power on the old site immediately without reconciling changed application data.
  2. Place every VM in one indiscriminate high-priority recovery group.
  3. Group machines into risk-based recovery plans and replication policies after discovery.
  4. Expect Azure Backup daily file restore to provide immediate powered-on workload failover.

Explanation

Correct Answer

C:

Recovery objectives and dependency maps drive replication cadence and sequencing.

Incorrect Answers

A:

Split-brain writes can corrupt recovered business state. In the present requirement, a VMware estate has many VMs with different recovery priorities. The needed design instead works because recovery objectives and dependency maps drive replication cadence and sequencing.

B:

A uniform group ignores business criticality and dependent components. This proposal contradicts the stated architecture constraint.

D:

Backup recovery may be slower and is not automatically an active VM replica. In the present requirement, a VMware estate has many VMs with different recovery priorities. The needed design instead works because recovery objectives and dependency maps drive replication cadence and sequencing.

Question 482

An architecture proposal for hybrid site disaster recovery relies on the following approach: Place every VM in one indiscriminate high-priority recovery group. Which specific failure or mismatch should the design reviewer identify?

  1. Backup recovery may be slower and is not automatically an active VM replica.
  2. Split-brain writes can corrupt recovered business state.
  3. A uniform group ignores business criticality and dependent components.
  4. RTO does not define how much committed data may be lost.

Explanation

Correct Answer

C:

Place every VM in one indiscriminate high-priority recovery group. A uniform group ignores business criticality and dependent components.

Incorrect Answers

A:

That assessment refers to the separate proposal 'Expect Azure Backup daily file restore to provide immediate powered-on workload failover.' not to the recommendation under review. Here, A uniform group ignores business criticality and dependent components.

B:

That assessment refers to the separate proposal 'Power on the old site immediately without reconciling changed application data.' not to the recommendation under review. Here, A uniform group ignores business criticality and dependent components.

D:

This concern applies to Interpret one-hour recovery time as permission to lose one hour of data. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because a uniform group ignores business criticality and dependent components.

Question 483

Acceptance testing must establish the following operational result: Tier-level evidence identifies where protection must improve. Which verification action most directly establishes that outcome?

  1. Measure last recoverable transaction and service restoration time in a drill.
  2. Compare test-failover timing against each tier's RTO and RPO.
  3. Prove reverse replication catches up before an approved failback.
  4. Rehearse workload recovery in Azure with network and DNS adjustments.

Explanation

Correct Answer

B:

Tier-level evidence identifies where protection must improve.

Incorrect Answers

A:

This is a test for A payments service permits fifteen minutes of data loss but must recover within one hour. The requirement here is instead demonstrated by compare test-failover timing against each tier's RTO and RPO.

C:

That verification addresses the different requirement: A failed on-premises site has recovered and workloads need a controlled return to primary. It does not directly establish tier-level evidence identifies where protection must improve.

D:

That verification addresses the different requirement: A physical on-premises Windows server must recover into Azure after a datacenter disaster. It does not directly establish tier-level evidence identifies where protection must improve.

Question 484

A failed on-premises site has recovered and workloads need a controlled return to primary. Which Azure architecture choice best meets this requirement?

  1. Plan supported reprotection and failback after validation of the restored site.
  2. Place every VM in one indiscriminate high-priority recovery group.
  3. Power on the old site immediately without reconciling changed application data.
  4. Expect Azure Backup daily file restore to provide immediate powered-on workload failover.

Explanation

Correct Answer

A:

Disaster recovery includes state convergence and reverse direction before cutback.

Incorrect Answers

B:

A uniform group ignores business criticality and dependent components. In the present requirement, a failed on-premises site has recovered and workloads need a controlled return to primary. The needed design instead works because disaster recovery includes state convergence and reverse direction before cutback.

C:

Split-brain writes can corrupt recovered business state. This proposal contradicts the stated architecture constraint.

D:

Backup recovery may be slower and is not automatically an active VM replica. In the present requirement, a failed on-premises site has recovered and workloads need a controlled return to primary. The needed design instead works because disaster recovery includes state convergence and reverse direction before cutback.

Question 485

An architecture proposal for hybrid site disaster recovery relies on the following approach: Power on the old site immediately without reconciling changed application data. Which specific failure or mismatch should the design reviewer identify?

  1. A single recent recovery point cannot satisfy historic retention.
  2. Split-brain writes can corrupt recovered business state.
  3. Backup recovery may be slower and is not automatically an active VM replica.
  4. A uniform group ignores business criticality and dependent components.

Explanation

Correct Answer

B:

Power on the old site immediately without reconciling changed application data. Split-brain writes can corrupt recovered business state.

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 split-brain writes can corrupt recovered business state.

C:

That assessment refers to the separate proposal 'Expect Azure Backup daily file restore to provide immediate powered-on workload failover.' not to the recommendation under review. Here, Split-brain writes can corrupt recovered business state.

D:

That assessment refers to the separate proposal 'Place every VM in one indiscriminate high-priority recovery group.' not to the recommendation under review. Here, Split-brain writes can corrupt recovered business state.

Question 486

Acceptance testing must establish the following operational result: Consistency checks prevent data divergence. Which verification action most directly establishes that outcome?

  1. List points from the requested years in the vault.
  2. Compare test-failover timing against each tier's RTO and RPO.
  3. Prove reverse replication catches up before an approved failback.
  4. Rehearse workload recovery in Azure with network and DNS adjustments.

Explanation

Correct Answer

C:

Consistency checks prevent data divergence.

Incorrect Answers

A:

This is a test for An audit demands monthly recovery points retained for several years. The requirement here is instead demonstrated by prove reverse replication catches up before an approved failback.

B:

That verification addresses the different requirement: A VMware estate has many VMs with different recovery priorities. It does not directly establish consistency checks prevent data divergence.

D:

That verification addresses the different requirement: A physical on-premises Windows server must recover into Azure after a datacenter disaster. It does not directly establish consistency checks prevent data divergence.

Question 487

A production SQL Database requires recovery from an accidental DROP TABLE and retention of annual regulatory restore points. Which TWO mechanisms are relevant? (Select TWO.)

  1. Configure supported SQL long-term retention for annual backups.
  2. Use point-in-time restore from an eligible pre-error recovery point.
  3. Add an availability zone and assume the dropped table reappears.
  4. Remove automated database backups to reduce storage cost.
  5. Use only a read replica as an immutable historic snapshot.

Explanation

Correct Answers

A:

LTR extends selected recovery points beyond normal PITR horizons.

B:

PITR can reconstruct the database before the logical deletion.

Incorrect Answers

C:

HA replicates the committed data change.

D:

Removing backups eliminates the required historical recovery capability.

E:

Live replicas can reproduce malicious or accidental updates.

Question 488

An architecture proposal for sql backup point in time and ltr relies on the following approach: Enable zone redundancy and expect it to undo a committed DROP TABLE. 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. RTO does not define how much committed data may be lost.
  4. Live replicas may contain the same erroneous write.

Explanation

Correct Answer

A:

Enable zone redundancy and expect it to undo a committed DROP TABLE. High availability replicates deletions instead of preserving prior logical state.

Incorrect Answers

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, High availability replicates deletions instead of preserving prior logical state.

C:

This concern applies to Interpret one-hour recovery time as permission to lose one hour of data. in another design solutions for backup and disaster recovery design. The current proposal specifically fails because high availability replicates deletions instead of preserving prior logical state.

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, High availability replicates deletions instead of preserving prior logical state.

Question 489

Acceptance testing must establish the following operational result: Historical row validation confirms an appropriate recovery point. Which verification action most directly establishes that outcome?

  1. Measure last recoverable transaction and service restoration time in a drill.
  2. Inspect yearly LTR points and retention expiration dates.
  3. Inject a test bad update and restore from a pre-change backup.
  4. Restore to just before the drop and query representative table rows.

Explanation

Correct Answer

D:

Historical row validation confirms an appropriate recovery point.

Incorrect Answers

A:

This is a test for A payments service permits fifteen minutes of data loss but must recover within one hour. The requirement here is instead demonstrated by restore to just before the drop and query representative table rows.

B:

That verification addresses the different requirement: Regulators require a yearly Azure SQL backup for ten years. It does not directly establish historical row validation confirms an appropriate recovery point.

C:

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 row validation confirms an appropriate recovery point.

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.
