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
✓
A hot site with synchronous replication.
Option A is correct because a hot site with synchronous replication ensures that data is written to both primary and secondary sites simultaneously, providing zero RPO and immediate failover. Option B (warm site) requires some time to bring systems online, leading to downtime and potential data loss. Option C (cold site) involves significant setup time and last-known-good backup restoration. Option D (cloud with daily snapshots) introduces an RPO of up to 24 hours, not zero data loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A warm site with asynchronous replication.
Why it's wrong here
Warm sites require time to activate and may lose data that hasn't been replicated since the last sync, resulting in a non-zero RPO.
- ✗
A cloud-based site with daily snapshots.
Why it's wrong here
Daily snapshots introduce a Recovery Point Objective (RPO) of up to 24 hours, meaning potential data loss of up to a full day.
- ✗
A cold site with tape restoration.
Why it's wrong here
Cold sites require hardware setup and tape restoration, leading to significant downtime and data loss up to the last backup.
- ✓
A hot site with synchronous replication.
Why this is correct
Synchronous replication ensures data is mirrored in real-time, enabling immediate failover with no data loss.
