The correct answer is to document the change and submit an emergency change request for retroactive approval. This is required because even in urgent situations where a vulnerability is being actively exploited, change management policies mandate that all changes—including emergency patches—must be formally recorded and submitted to the Change Advisory Board (CAB) for post-implementation approval. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of the emergency change process and the critical distinction between bypassing pre-approval and skipping documentation entirely. A common trap is assuming that an emergency justifies ignoring policy altogether, but the exam emphasizes that retroactive approval preserves audit trails and compliance. Remember the memory tip: “Patch now, paper later—but always paper.”
220-1102 Documentation and Change Management Practice Question
This 220-1202 practice question tests your understanding of documentation and change management. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 company’s change management policy requires all changes to be approved by the Change Advisory Board (CAB) before implementation. A technician applies an emergency security patch to a critical server without CAB approval because the vulnerability is being actively exploited. What should the technician do after applying the patch?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Document the change and submit an emergency change request for retroactive approval.
Even in emergency changes, documentation and retroactive approval are required. The technician must document the change and notify the CAB as soon as possible to obtain retroactive approval, ensuring compliance with change management policies.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Wait for the next CAB meeting to report the change.
Why it's wrong here
Waiting could delay necessary documentation and approval; the technician should notify the CAB immediately.
✓
Document the change and submit an emergency change request for retroactive approval.
Why this is correct
This follows the correct procedure for emergency changes: document and seek retroactive approval from the CAB.
Related concept
Static NAT maps one inside address to one outside address.
✗
Revert the patch and wait for CAB approval.
Why it's wrong here
Reverting a critical security patch during an active exploit would leave the system vulnerable, which is not advisable.
✗
Delete the change log entry to avoid accountability.
Why it's wrong here
Deleting entries is unethical and violates documentation policies; it could lead to disciplinary action.
Common exam traps
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.
Detailed technical explanation
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.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
