Difficulty: MediumChange Management Processes

A network engineer is preparing a change request to modify core routing table entries across several regional branch offices. The engineer has defined the business purpose, documented the precise scope, performed a thorough risk assessment, and scheduled the change during a standard maintenance window. During review, the Change Advisory Board (CAB) rejects the submission as incomplete. Which of the following critical change management elements was most likely missing from the engineer's submission?

  1. A documented rollback plan outlining specific recovery steps if network connectivity fails during deploymentAnswer
  2. B
    A completed post-implementation testing log confirming successful data packet transmission across all branches
  3. C
    An emergency bypass authorization waiving end-user notification requirements for routine maintenance
  4. D
    A forensic chain of custody log detailing the hardware serial numbers of all physical branch routers

Answer

A documented rollback plan outlining specific recovery steps if network connectivity fails during deployment
Formal change management procedures require a documented rollback (backout) plan to be included in the change request prior to submission to the Change Advisory Board (CAB). The rollback plan ensures that technicians can quickly restore systems to their previous working state if the implemented change causes unanticipated network outages or instability.

Step-by-Step Solution

1
Analyze the change request components provided in the scenario.
The engineer included the purpose, scope, risk assessment, and proposed deployment schedule.
CompTIA change management processes require specific core components before CAB approval can be granted.
2
Identify missing mandatory change request components.
The submission lacked a rollback (backout) plan, end-user notification strategy, or pre-testing plan.
Without a rollback plan, the organization risks prolonged downtime if the configuration change introduces unexpected routing loops or site outages.
3
Evaluate the choices to select the missing requirement.
The option specifying a documented rollback plan identifies the necessary pre-approval document required by the CAB.
CAB approval depends on risk mitigation strategies, including an explicit step-by-step backout procedure.
