CV0-004 Practice Question: A cloud administrator is designing a backup…
A cloud administrator is designing a backup strategy for a critical database that must achieve a recovery point objective (RPO) of 15 minutes and a recovery time objective (RTO) of 30 minutes. The database has a high write throughput. Which of the following backup methods BEST meets these requirements?
⚠ Common exam trap
A common mix-up: candidates choose synchronous log shipping (Option A) thinking it provides the best RPO, but they overlook the severe write-throughput penalty and the fact that RTO can be longer due to failover complexity, while snapshot replication offers a better balance for high-write environments.
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
✓
Snapshot replication to a secondary datastore every 10 minutes.
Snapshot replication to a secondary datastore every 10 minutes meets the RPO of 15 minutes because snapshots can be taken at intervals shorter than the RPO (e.g., every 10 minutes), and the RTO of 30 minutes is achievable if the secondary datastore is ready to be promoted quickly. For a high-write-throughput database, snapshot replication minimizes performance impact compared to synchronous log shipping, which can throttle writes due to network latency.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Synchronous log shipping to a standby database.
Why it's wrong here
Log shipping may require manual failover, potentially exceeding the RTO.
- ✗
Full daily backups with transaction log backups every hour.
Why it's wrong here
Hourly log backups result in an RPO of up to one hour, exceeding the 15-minute requirement.
- ✓
Snapshot replication to a secondary datastore every 10 minutes.
Why this is correct
Snapshots provide point-in-time copies that can be restored quickly, meeting RPO and RTO.
- ✗
Incremental backups every 10 minutes.
Why it's wrong here
Incremental backups still require a full restore chain, which can take longer than 30 minutes.
