CS0-003 Practice Question: After a high-priority SOC escalation, an incident…
After a high-priority SOC escalation, an incident was contained successfully, but delayed escalation allowed the attacker more dwell time. What should the post-incident review produce? During eradication, which decision is most defensible? which response best matches incident-response practice?
⚠ Common exam trap
CompTIA often tests the concept that post-incident reviews must produce concrete, process-improvement artifacts (like updated playbooks) rather than punitive or vague outputs, and candidates mistakenly choose blame or deletion due to a misunderstanding of incident response maturity.

Correct answer & explanation
✓
Specific playbook updates, escalation triggers, owners, and due dates
A post-incident review (PIR) should produce actionable improvements, not generic statements or blame. Specific playbook updates, escalation triggers, owners, and due dates directly address the delayed escalation by refining incident response procedures, ensuring future incidents are escalated faster and with clear accountability. This aligns with NIST SP 800-61 Rev. 2 guidance on lessons learned and process improvement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A generic statement that security is important
Why it's wrong here
Useful reviews create concrete actions.
- ✗
Deletion of all incident tickets
Why it's wrong here
Tickets provide evidence and improvement history.
- ✗
A blame list of individual analysts
Why it's wrong here
Blame-focused reviews discourage reporting and do not fix process gaps.
- ✓
Specific playbook updates, escalation triggers, owners, and due dates
Why this is correct
Lessons learned should translate findings into trackable process improvements. In eradication, responders need action that reduces risk while preserving the investigation record.
