220-1102 Practice Question: A technician completes an approved firmware…
This 220-1102 practice question tests your understanding of a technician completes an approved firmware…. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 technician completes an approved firmware update on a network switch. After the update, the switch functions correctly, but the management interface now requires HTTPS instead of HTTP. The change plan only mentioned updating firmware to patch a security vulnerability. According to change management best practices, what should the technician do NEXT?
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
Distractor review
Revert the firmware to the previous version to restore HTTP access
Reverting would undo the security patch and may cause downtime. The switch is functioning; the issue is a configuration change outside the plan, not a failure.
B
Best answer
Document the HTTPS change and submit a post-change report to the CAB
Best practices require documenting all changes, including unintended ones. The technician should inform the CAB of the new configuration so they can assess and approve if needed.
C
Distractor review
Leave the configuration as is since HTTPS improves security
While HTTPS is more secure, any deviation from the approved plan must be documented and approved. Simply leaving it without documentation violates change management procedures.
D
Distractor review
Disable HTTPS and configure the switch to use HTTP only
Manually reverting the configuration without authorization could cause further issues. The change management process requires that all alterations be reviewed.
Answer analysis
Why the other options are wrong
Understanding why incorrect options are tempting is as important as knowing the correct answer.
- ✗
Revert the firmware to the previous version to restore HTTP access
Reverting would undo the security patch and may cause downtime. The switch is functioning; the issue is a configuration change outside the plan, not a failure.
- ✗
Leave the configuration as is since HTTPS improves security
While HTTPS is more secure, any deviation from the approved plan must be documented and approved. Simply leaving it without documentation violates change management procedures.
- ✗
Disable HTTPS and configure the switch to use HTTP only
Manually reverting the configuration without authorization could cause further issues. The change management process requires that all alterations be reviewed.
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: Document the HTTPS change and submit a post-change report to the CAB — After completing a change, the technician must document the actual outcome, including any deviations from the plan. Even though HTTPS is more secure, the change resulted in an unexpected configuration change. The technician should document the new state (HTTPS required) and submit a post-change report to the Change Advisory Board (CAB) for review. The switch is functional, so reverting is not immediately needed, but the change request should reflect what actually happened.
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.
