Full question →mediummultiple choiceObjective-mapped
A change advisory board (CAB) approves an emergency change to apply a critical security patch to a critical server. After the patch is applied and the server is verified operational, the technician completes the documentation. According to change management best practices, what post-implementation step is unique to emergency changes?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Schedule a post-implementation review within 30 days
Correct. Emergency changes require a post-implementation review to validate the change and ensure proper documentation after the fact.
B
Distractor review
Notify all users about the change
Incorrect. Notification to users may be part of any change, not unique to emergency changes.
C
Distractor review
Revert the change if not approved later
Incorrect. Reverting is not a standard requirement; the change is already approved as emergency.
D
Distractor review
Obtain verbal approval from the CEO
Incorrect. Emergency changes may require specific approvals, but involving the CEO is not a universal best practice.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this 220-1102 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Schedule a post-implementation review within 30 days — Emergency changes bypass the normal approval process due to urgency. To ensure accountability and proper oversight, a post-implementation review (PIR) is typically required within a specified timeframe (e.g., 30 days). During the PIR, the change is reviewed to ensure it was justified, documented correctly, and that any lessons learned are captured. This step is not required for standard or normal changes because they already went through full approval. Notifying users is not unique to emergency changes. Reverting is not a standard step unless something went wrong. Verbal approval from the CEO is not a standard process.
