Quick Answer
The correct answer is that the three essential steps in the post-incident review process are conducting a root cause analysis, identifying improvements, and updating the Incident Response Plan (IRP). These steps are critical because a post-incident review is not about punishment but about systemic learning: the root cause analysis digs into the underlying technical or procedural failure, the identification of improvements translates those findings into actionable changes, and updating the IRP ensures the organization’s playbook evolves to prevent recurrence. On the Certified Information Security Manager CISM exam, this question tests your understanding of the “lessons learned” phase within the incident response lifecycle, often appearing as a multiple-select item designed to trap candidates who confuse blame assignment with process improvement. A common memory tip is to remember the three “U”s: Uncover the root cause, Upgrade the controls, and Update the plan—skipping any one of these leaves the organization vulnerable to the same incident.
This CISM practice question tests your understanding of incident management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE steps are essential in the post-incident review process?
Identify lessons learned and process improvements
Continuous improvement is a primary goal.
Update the incident response plan
Updating the plan incorporates findings.
Assign blame for the incident
Why wrong: Blaming individuals hinders learning.
Conduct a root cause analysis
Root cause prevents recurrence.
Renew vendor contracts
Why wrong: Contract renewal is not a standard post-incident step.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Identify lessons learned and process improvements
Options A, C, and D are correct: identifying improvements, root cause analysis, and updating the IRP are key. Option B is wrong because assigning blame is counterproductive. Option E is wrong because vendor contracts are not necessarily reviewed unless relevant.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
