Active-passive with synchronous replication
Active-passive with synchronous replication provides fast failover and minimal data loss, meeting the RTO of 15 minutes and RPO of 5 minutes. Hot standby can fail over quickly, but synchronous replication ensures the RPO.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Active-passive with synchronous replication
Why this is correct
Synchronous replication ensures RPO; failover is fast, meeting RTO.
- ✗
Warm standby
Why it's wrong here
Warm standby may have longer recovery time and potential data loss.
- ✗
Active-active with asynchronous replication
Why it's wrong here
Asynchronous replication may result in data loss beyond RPO.
- ✗
Cold standby
Why it's wrong here
Cold standby has long recovery time, not meeting RTO of 15 minutes.
