220-1102 Operational Procedures Practice Question
A technician has received approval from the Change Advisory Board (CAB) to decommission an old server that hosts a legacy application. The decommissioning is completed successfully. The next day, users report that a critical monthly report no longer runs. The technician discovers that the report depended on a scheduled task on the old server that was not migrated. According to change management best practices, what should the technician have done to prevent this issue?
⚠ Common exam trap
The trap here is that candidates often focus on testing or backout plans (options A and B) because they are common change management steps, but the question specifically tests the requirement to identify and include all dependencies in the change request before CAB approval, which is the only way to prevent the oversight of a critical scheduled task.

Correct answer & explanation
✓
Included all dependencies in the change request
Change management best practices require that all dependencies—including scheduled tasks, scripts, and data sources—be identified and documented in the change request before approval. The technician failed to include the legacy server’s scheduled task that triggered the critical monthly report, so the CAB could not assess the full impact of the decommissioning. By listing every dependency, the technician would have ensured the scheduled task was migrated or recreated before the old server was taken offline.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Created a detailed backout plan
Why it's wrong here
A backout plan is for reverting the change if it fails, but it does not prevent the omission of dependencies. The issue here was not including the scheduled task in the scope of the change.
- ✗
Tested the change in a staging environment first
Why it's wrong here
Testing in a staging environment is a valuable validation step, but it only catches functional defects that the test scenarios are designed to reveal. A scheduled task that resides on the source server and references local paths or credentials may not be exercised by a staging test, especially if the test focuses on application behavior rather than server configuration. Even if staging testing exposed the missing task, the fundamental process failure remains: the change request did not enumerate this dependency, so the CAB approved a plan that ignored it.
- ✗
Documented the change in the change log after completion
Why it's wrong here
Documenting a change in the change log after completion satisfies audit and communication requirements, but it is inherently retrospective. At that point the implementation has already occurred, and any dependency that was omitted from the approved change request has already been left behind on the source system. The correct practice is to identify and include all dependencies in the change request before CAB approval; post-implementation documentation merely records the resulting incident, it does not prevent it.
- ✓
Included all dependencies in the change request
Why this is correct
Change management best practices require that all dependencies (like scheduled tasks, shared resources, and data) be identified and included in the change plan. This ensures they are migrated or accounted for before the change is implemented.
