A technician is dispatched to replace a faulty power supply in a desktop computer. According to change management best practices for standard repairs, what should the technician do BEFORE replacing the power supply?
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.
Distractor review
Get approval from the Change Advisory Board (CAB)
Incorrect: Change advisory board (CAB) approval is generally required for major or high-risk changes, not for standard hardware replacements like a power supply.
Distractor review
Inform the user of the replacement plan
Incorrect: While communicating with the user is important, the formal change management step is to create and document the change in a ticketing system.
Best answer
Create or update an incident/ticket documenting the problem and planned replacement
Correct: The technician should create or update an incident or change ticket documenting the problem and the planned replacement before starting the work.
Distractor review
Test the old power supply to confirm failure
Incorrect: Testing the old power supply after it has already been identified as defective is inefficient and not a required change management step.
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: Create or update an incident/ticket documenting the problem and planned replacement — Even for routine hardware replacements, proper change management requires documenting the issue and planned action in a ticket before proceeding. This ensures traceability and approval workflow is followed. Checking the change board is typically reserved for higher-risk changes. Informing the user is good practice but not the primary policy requirement. Testing the old PSU after failure is unnecessary and wastes time.
