A company is designing a cloud architecture that must meet a recovery time objective (RTO) of 4 hours and a recovery point objective (RPO) of 1 hour for a critical database. The database is 500 GB and runs on a virtual machine. Which backup strategy should be used?
⚠ Common exam trap
It's easy for candidates to confuse high-availability replication (Option C) with a backup strategy, failing to recognize that replication does not protect against logical corruption or allow granular point-in-time recovery to meet RPO requirements.
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
✓
Take daily snapshots and transaction log backups every hour
Daily snapshots provide a baseline recovery point, and hourly transaction log backups ensure that the RPO of 1 hour is met by limiting data loss to at most one hour of transactions. Combined with the ability to restore from the latest snapshot and apply transaction logs, this strategy can achieve an RTO of 4 hours for a 500 GB database, assuming adequate infrastructure and restore automation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Take daily snapshots and transaction log backups every hour
Why this is correct
Meets both RTO and RPO.
- ✗
Take full backups weekly and differential backups daily
Why it's wrong here
Cannot achieve 1-hour RPO.
- ✗
Use continuous database replication to a standby instance
Why it's wrong here
This is a high-availability solution, not a backup strategy.
- ✗
Perform block-level incremental backups every 4 hours
Why it's wrong here
Exceeds 1-hour RPO.
