Which THREE of the following are key metrics to include in a disaster recovery test report? (Select exactly 3.)
⚠ Common exam trap
A common mix-up: candidates confuse operational metrics (like cost or personnel count) with technical DR success metrics, leading them to select B or D instead of focusing on RPO, RTO, and restore integrity.

Correct answer & explanation
✓
Amount of data lost (actual vs. RPO)
The amount of data lost (actual vs. RPO) directly measures whether the recovery process met the Recovery Point Objective. This metric validates the effectiveness of backup frequency and replication lag, which is critical for determining if the DR plan preserved data integrity within acceptable loss limits.
