Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
When the incident cannot be resolved within the maximum tolerable downtime (MTD)
Why this is correct
If MTD cannot be met, BC/DR plans are triggered to restore operations.
- ✗
Immediately upon detection of any incident
Why it's wrong here
Most incidents are handled by IR without BC/DR activation.
- ✗
Only after the incident is fully contained
Why it's wrong here
Containment may happen before BC/DR, but activation is based on MTD.
- ✗
When the incident exceeds the recovery time objective (RTO) but is still within MTD
Why it's wrong here
Activation occurs when MTD is at risk, not just RTO.
