220-1102 Operational Procedures Practice Question
A technician is implementing a change to migrate a file server to new hardware. The change management plan requires a rollback plan. Which of the following BEST describes a rollback plan?
⚠ Common exam trap
Candidates often confuse a backup (a static asset) with a rollback plan (a dynamic procedure), leading them to select Option B because they think having a backup is sufficient for reverting changes, but the exam emphasizes that a rollback plan must include actionable steps, not just data preservation.

Correct answer & explanation
✓
A detailed guide to revert changes
A rollback plan is a predefined set of steps to revert a system to its previous state if a change fails. In the context of migrating a file server to new hardware, a rollback plan ensures that if the migration encounters errors (e.g., data corruption, connectivity loss, or performance degradation), the technician can quickly restore the original server configuration and data, minimizing downtime. Option A correctly identifies this as a detailed guide to revert changes, which is the core requirement of a rollback plan in change management.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A detailed guide to revert changes
Why this is correct
A rollback plan must be a written, step-by-step runbook that specifies the exact commands, verification checks, and order of operations to revert the file server to its original hardware. It includes criteria for when to trigger the rollback (e.g., failed data integrity checks or performance thresholds) and explicitly defines the target state to restore, ensuring minimal downtime and no guesswork during an incident.
- ✗
A backup of the current configuration
Why it's wrong here
A backup of the current configuration is a snapshot or artifact—such as a VHD, GPO backup, or registry export—that can be used to restore settings, but it is not itself a plan. To use it as a rollback you still need a procedure for relaunching the old server, remapping shares, re-acl'ing data, and verifying service health; without that documented process, the backup alone does not guarantee a successful revert.
- ✗
A list of all affected users
Why it's wrong here
A list of affected users identifies the stakeholders who might experience downtime or need communication before and after the migration, but it does not describe how to undo the change. It is an input to an impact analysis and a communication plan, not a sequence of reversal steps. In a rollback context, you would consult that list only to notify users of the reverted state, not to execute technical restoration.
- ✗
A timeline for the change
Why it's wrong here
A timeline for the change defines the schedule for execution windows, cutover, and validation milestones—useful for coordinating the migration, but it is orthogonal to the rollback plan. Even if the timeline shows when to abort, it omits the actual technical steps to revert. A proper rollback plan is a conditional procedure that can be executed at any point in the timeline, independent of when the change was scheduled.
