Difficulty: MediumChange Management Processes

A systems engineer is preparing a change request to update the host hypervisor software across a cluster supporting mission-critical virtualized applications. The engineer has defined the scope of change, documented the business purpose, and completed a comprehensive risk analysis. Which of the following is the MOST critical required component that must be included in the change proposal prior to submitting it to the Change Advisory Board (CAB) for approval?

  1. A documented rollback plan specifying recovery procedures if the hypervisor update causes system failureAnswer
  2. B
    Results from post-implementation acceptance testing performed on live production cluster nodes
  3. C
    Authorization to bypass CAB approval provided the update is scheduled during an off-peak maintenance window
  4. D
    Preliminary deployment of the update on a single live production host to evaluate stability

Answer

A documented rollback plan specifying recovery procedures if the hypervisor update causes system failure
Under standard IT operational procedures, a formal change proposal submitted for CAB evaluation must include the scope of change, purpose, risk assessment, and a documented rollback plan. The rollback plan ensures that technicians can quickly revert infrastructure to a functional state if the upgrade encounters unexpected faults.

Step-by-Step Solution

1
Analyze the current stage of the change management workflow in the scenario.
The systems engineer is preparing the change proposal prior to submitting it to the Change Advisory Board (CAB).
Complete change documentation is required before the CAB can evaluate risks and grant approval.
2
Identify missing mandatory change request components based on standard CompTIA change control procedures.
Scope, purpose, and risk analysis are complete, but back-out/rollback procedures have not been specified.
A formal rollback plan is essential to ensure systems can be restored to a known good state if the change fails.
3
Select the choice representing the necessary pre-submission requirement.
Developing and attaching a documented rollback plan to the request.
Rollback planning directly mitigates service disruption during major software and system updates.
