CV0-004 Operations and Support Practice Question
During a disaster recovery drill, a cloud engineer discovers that the RTO for a critical application is not being met. The application runs on EC2 instances with data in EBS volumes. Which change would most likely improve the RTO?
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
✓
Enable cross-region replication for the EBS snapshots
Cross-region replication of EBS snapshots reduces the time to have data available in the recovery region. Changing replication frequency doesn't affect recovery time if snapshots are not pre-replicated. Using larger instances may not help if data transfer is the bottleneck. Scheduled scaling is unrelated to DR recovery.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Increase the frequency of EBS snapshots from daily to hourly
Why it's wrong here
More frequent snapshots reduce RPO, not RTO, as you still need to restore from the latest snapshot.
- ✓
Enable cross-region replication for the EBS snapshots
Why this is correct
Having snapshots already in the recovery region eliminates the time needed to copy them during recovery.
- ✗
Configure scheduled scaling to pre-warm instances in the recovery region
Why it's wrong here
Scheduled scaling is for auto-scaling, not for DR recovery time.
- ✗
Increase the EC2 instance size in the recovery region
Why it's wrong here
Larger instances may help performance but not the time to restore data from snapshots.
