Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Mean time to repair (MTTR) and mean time between failures (MTBF)
Why it's wrong here
These are reliability metrics, not BIA outputs.
- ✓
Recovery time objective (RTO) and recovery point objective (RPO)
Why this is correct
RTO is 8 hours, RPO is 15 minutes.
- ✗
Service level objective (SLO) and service level agreement (SLA)
Why it's wrong here
SLO and SLA are service metrics, not recovery metrics.
- ✗
Maximum tolerable downtime (MTD) and working recovery time (WRT)
Why it's wrong here
MTD is similar to RTO, but the question mentions both downtime and data loss, so RTO and RPO are more precise.
