220-1102 Practice Question: A change to apply a critical security patch to a…
This 220-1102 practice question tests your understanding of a change to apply a critical security patch to a…. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A change to apply a critical security patch to a production application server has been approved by the Change Advisory Board (CAB) with a detailed implementation plan. During the scheduled maintenance window, the technician begins the patching process and discovers that a required prerequisite update is not installed on the server. The prerequisite update is available for download but was not included in the approved change plan. According to change management best practices, what should the technician do FIRST?
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
Stop the implementation and initiate the backout plan defined in the change request
This follows change management best practices by preventing unauthorized changes and allowing the server to be restored to a known good state while a new change request is created.
B
Distractor review
Continue with the approved change and note the prerequisite as a post-implementation issue
Continuing without the prerequisite could cause the patch to fail or make the server unstable, and it violates change management by ignoring the approved plan.
C
Distractor review
Contact the CAB chair for emergency approval to apply the prerequisite
While emergency changes exist, the immediate step is to stop the change and roll back; seeking emergency approval may be appropriate afterward but is not the first action.
D
Distractor review
Download and apply the prerequisite update immediately to proceed with the patch
This circumvents the change management process and introduces unapproved changes, which could lead to conflicts or unanticipated downtime.

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.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Question 1
A change advisory board (CAB) approved a standard change to update antivirus definitions on all servers. The technician completes the update on a file server and verifies the server is functioning normally. According to change management best practices, what documentation should the technician complete?
Question 2
A company's change management policy requires all server changes to be approved by the Change Advisory Board (CAB). A technician discovers that a critical database server's operating system needs a security patch to comply with a new regulatory requirement that takes effect in one week. The patch has a known risk of causing service downtime. The next scheduled CAB meeting is in two weeks. What should the technician do FIRST?

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: Stop the implementation and initiate the backout plan defined in the change request — Change management best practices require strict adherence to the approved change plan. Deviating from the plan by installing an unapproved prerequisite introduces risk and bypasses the review process. The technician should stop the implementation and initiate the agreed-upon backout or rollback plan to restore the server to its pre-change state. After that, a new change request should be submitted to include the prerequisite update and be re-approved by the CAB. Continuing with the change (Option B) or downloading and applying the prerequisite without approval (Option D) violates change management policy. Contacting the CAB for emergency approval (Option C) might be considered, but the immediate action should be to stop and roll back, as the change cannot proceed safely.
What should I do if I get this 220-1102 question wrong?
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1102 NAT questions on configuration and troubleshooting.
