200-201 Security Policies and Procedures Practice Question
After resolving a security incident, the IR team conducts a lessons learned meeting. Which of the following are typical outputs of this post-incident activity? (Choose three.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Recommendations for policy or procedure changes
Lessons learned leads to updating the IR plan, identifying metrics to measure performance, and recommending changes to policies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Recommendations for policy or procedure changes
Why this is correct
The meeting generates recommendations for policy or procedure changes, such as revised escalation paths, access controls or detection rules. These outputs directly address root causes found during the incident, satisfying the post-incident objective of improving organisational defences.
- ✗
Creation of new detection signatures for future incidents
Why it's wrong here
Lessons learned produces documentation and process improvements, not new detection signatures, which belong to detection engineering and tuning during or after response. It is tempting because improved detection often follows an incident, but signature creation is a separate engineering deliverable, not a meeting output.
- ✗
Immediate containment of the incident
Why it's wrong here
Containment happens during the response phase, before eradication and recovery, so it cannot be an output of a lessons learned meeting held after resolution. It is tempting because containment is a genuine incident response activity, but the stem asks specifically for post-incident outputs such as report updates and process improvements.
- ✓
Development of metrics to measure response effectiveness
Why this is correct
Metrics measuring response effectiveness, such as mean time to detect and contain, are typical outputs. They quantify whether the IR process met its objectives and provide baselines for comparing future incidents, fulfilling the post-incident activity's evaluation purpose.
- ✓
Updated incident response plan based on findings
Why this is correct
Lessons learned meetings produce a revised incident response plan incorporating identified gaps, updated playbooks and improved procedures. This satisfies the post-incident activity requirement to feed findings back into the IR capability, reducing recurrence and improving future response.
