1. Which sequence best represents a standard incident response lifecycle?

Difficulty: EasyType: MCQTopic: IR/Forensics

Good response work starts before day one. Preparation builds playbooks, access, tools, and comms. Then you detect and analyze what really happened. Containment limits blast radius while you plan. Eradication removes root cause, not just symptoms. Recovery brings systems back safely with extra monitoring. Finally, lessons learned feeds fixes into people, process, and tech so the same issue does not return.

2. During evidence collection, which order of volatility is the most appropriate?
