Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Conducting a penetration test against the entire production network
Why it's wrong here
This is a separate validation activity, not part of the standard incident post-mortem process.
- ✓
Reviewing the incident timeline to identify gaps in detection
Why this is correct
Analyzing the timeline helps identify where the process delayed detection or response.
- ✗
Archiving all evidence in a cold storage bucket for 50 years
Why it's wrong here
While evidence must be retained, this is a storage policy, not a lessons-learned activity.
- ✓
Developing a post-incident report detailing what went right and what went wrong
Why this is correct
This documentation is the cornerstone of the institutional learning process.
- ✓
Updating standard operating procedures (SOPs) based on identified operational failures
Why this is correct
SOPs must be refined to address the weaknesses revealed during the incident.
