Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Measure the time taken to restore services from backups.
Key DR drill activities include verifying the recovery time, checking data freshness to validate RPO, and conducting failover testing to ensure the process works. Chaos engineering is for resilience testing but not specifically for RTO/RPO validation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Review cost optimization recommendations for the DR environment.
Why it's wrong here
Cost optimization is not part of DR drill validation.
- ✓
Measure the time taken to restore services from backups.
Why this is correct
This tests whether RTO is met.
- ✗
Run chaos engineering experiments to introduce random failures.
Why it's wrong here
Chaos engineering tests resilience, not RTO/RPO compliance.
- ✓
Perform a failover to the DR site and verify application functionality.
Why this is correct
Failover testing validates the entire recovery process.
- ✓
Check the timestamp of the most recent backup or replica to ensure data is within RPO.
Why this is correct
This validates that data loss is within acceptable limits.
