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
✓
Implement continuous replication to a standby database
Pre-warming standby instances reduces launch time, using faster storage like Provisioned IOPS speeds up data access, and implementing continuous replication reduces the amount of data to restore.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement continuous replication to a standby database
Why this is correct
Continuous replication keeps the standby database nearly in sync, reducing recovery time.
- ✓
Pre-warm standby database instances in the recovery region
Why this is correct
Pre-warmed instances reduce the time needed to provision resources during failover.
- ✗
Disable encryption on the database to reduce overhead
Why it's wrong here
Disabling encryption might slightly reduce overhead but is a security risk and not a standard recommendation.
- ✗
Increase the retention period of automated backups
Why it's wrong here
Longer retention does not speed up restoration; it increases storage costs.
- ✓
Use provisioned IOPS storage for the database volumes
Why this is correct
Higher IOPS can speed up data restoration and read/write operations.
