MTTC refers to the average time between the start and resolution of an incident (sometimes called MTTR for mean-time-to-resolve).

• A. The average time to detect an incident.
• B. The time to recover from an incident.
• C. The average time between the start and resolution of an incident (mean-time-to-resolve).
• D. The time to patch a vulnerability

Answer: (C)

MTTR stands for mean-time-to-resolve, and it measures the total time from when an incident starts (or is detected) to when it is fully resolved and service is restored. This end-to-end measure shows how quickly an organization can diagnose, fix, and verify that the issue is resolved, reflecting the effectiveness of incident response and remediation processes. The option that describes the average time between the start and resolution matches this definition exactly. Other options point to different timing aspects—time to detect (MTTD) or time to patch—so they don’t describe MTTR as precisely.
