CV0-004 Practice Question: An administrator is configuring a backup policy…
An administrator is configuring a backup policy for a critical application database. The policy must allow point-in-time recovery up to the last 5 minutes. The database is updated continuously throughout the day. Which of the following backup strategies BEST meets the requirement?
⚠ Common exam trap
Watch out — candidates often confuse crash-consistent snapshots (Option B) with application-consistent backups, failing to realize that VM snapshots do not capture transaction log details needed for precise point-in-time recovery of a database.

Correct answer & explanation
✓
Daily full backups plus transaction log backups every 5 minutes.
It combines daily full backups with transaction log backups every 5 minutes, which is the only strategy that supports point-in-time recovery (PITR) to within 5 minutes for a continuously updated database. Transaction log backups capture every committed transaction, allowing restoration to any specific point in time by replaying logs from the last full backup.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Weekly full backups with daily differential backups.
Why it's wrong here
Differential backups are cumulative and do not allow point-in-time recovery.
- ✗
Hourly snapshots of the virtual machine.
Why it's wrong here
Snapshots capture state but may not be transaction-consistent and lack granularity.
- ✓
Daily full backups plus transaction log backups every 5 minutes.
Why this is correct
Transaction logs enable recovery to any point within the last 5 minutes.
- ✗
Daily full backups of the database.
Why it's wrong here
Daily backups would lose up to 24 hours of data.
