220-1102 Operational Procedures Practice Question
A technician is implementing a change to update the operating system on several servers. The change management plan includes a rollback plan. What should the rollback plan specify?
⚠ Common exam trap
It's easy for candidates to confuse the rollback plan with the implementation plan, mistakenly thinking the rollback plan should describe how to apply the change rather than how to undo it.

Correct answer & explanation
✓
The steps to revert to the previous configuration if the change fails.
A rollback plan is specifically designed to revert the system to its previous known-good state if the change fails or causes unexpected issues. In the context of server OS updates, this ensures business continuity by detailing exact steps to restore the original configuration, such as reinstalling the prior OS version from backup or reverting system snapshots.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The steps to revert to the previous configuration if the change fails.
Why this is correct
The steps to revert to the previous configuration if the change fails are the essence of a rollback plan. This contingency procedure specifies how to restore the operating system to its pre-change state, such as applying a system image backup, uninstalling the update, or reverting configuration files. It is activated only when the change is unsuccessful, ensuring minimal downtime and recovery to a known-good baseline.
- ✗
The steps to implement the change successfully.
Why it's wrong here
The steps to implement the change successfully describe the implementation plan, not the rollback plan. This includes the ordered tasks to deploy the operating system update, such as pre-installation checks, staging, and executing the installation. Unlike a rollback plan, which focuses on undoing the change, the implementation plan focuses on carrying it out, so it is incorrect for this question.
- ✗
The approval from the change advisory board.
Why it's wrong here
Approval from the change advisory board (CAB) is a governance authorization that permits the change to be scheduled and executed. It is a prerequisite that must be obtained before implementation, but it is not a set of recovery procedures. The rollback plan is a technical document detailing how to restore the previous configuration, while CAB approval is a managerial sign-off, so this option is wrong.
- ✗
The list of users affected by the change.
Why it's wrong here
The list of users affected by the change is part of an impact analysis, which identifies who or what may be impacted by the update. This information is used for communication, scheduling, and risk assessment, but it does not contain recovery steps. A rollback plan, in contrast, details how to undo the change and restore the original state, making the user list an unrelated aspect.
