Full question →mediummultiple choiceObjective-mapped
A company follows a strict change management process. A technician is applying a critical security patch to a web server during a scheduled maintenance window. The patch was fully tested in a lab environment and approved by the Change Advisory Board (CAB). During the installation, the technician discovers that the patch requires a software dependency that is not installed on the server. 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
Distractor review
Install the required dependency and then proceed with the patch
Installing an untested dependency outside the approved plan introduces risk and violates change management procedures.
B
Best answer
Abort the change and follow the backout plan to restore the server
This is the correct first step according to change management. It preserves the server's stability and allows for proper reassessment.
C
Distractor review
Contact the CAB for immediate approval of the dependency
While contacting the CAB is important, the immediate action should be to abort the change and secure the system. Approval should be sought after backout.
D
Distractor review
Apply the patch anyway and monitor the server for issues
Applying the patch without the required dependency would likely cause it to fail or destabilize the server. This is not a safe action.
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.

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: Abort the change and follow the backout plan to restore the server — Change management best practices require that any unplanned deviation from the approved change plan must be handled carefully. The first step is to abort the change and follow the backout plan to restore the server to its original state. This ensures stability and allows for proper evaluation of the new dependency. Installing the dependency without prior approval violates change management, as would applying the patch without the dependency. Contacting the CAB may be necessary later, but the immediate priority is to revert the change.
