After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO actions can help reduce the recovery time objective (RTO) for an Amazon RDS for PostgreSQL DB instance in the event of a failure? (Choose 2.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable Multi-AZ deployment.
Options B and C are correct because Multi-AZ provides automatic failover, and automated backups with point-in-time recovery enable fast restore. Option A is wrong because Read replicas are for read scaling, not failover. Option D is wrong because manual snapshots are not automated and slower. Option E is wrong because increasing instance size does not reduce RTO.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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 DB instance class size.
Why it's wrong here
Instance size does not affect failover time.
✓
Enable Multi-AZ deployment.
Why this is correct
Multi-AZ provides automatic failover to a standby.

✗
Create a read replica in a different Availability Zone.
Why it's wrong here
Read replicas are not used for automatic failover.
✓
Configure automated backups with point-in-time recovery.
Why this is correct
Automated backups allow fast restore to a point in time.

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
