Difficulty: EasyConfiguration and Change Management

Prior to performing a major routing protocol modification on an enterprise core network, an engineer must submit documentation detailing how to undo the modifications should performance degrade. Which of the following change management elements fulfills this requirement?

  1. A rollback plan outlining explicit trigger conditions and step-by-step restoration proceduresAnswer
  2. B
    A sequential media log for full and incremental data backup sets
  3. C
    A hypothesis testing protocol based on standard troubleshooting steps
  4. D
    A cryptographic SNMPv3 authentication profile configuration

Answer

A rollback plan outlining explicit trigger conditions and step-by-step restoration procedures
A rollback plan is an essential component of change management documentation. It explicitly details the steps, commands, resources, and decision thresholds required to safely restore a network device or service to its previous stable configuration if a change fails or destabilizes the environment.

Step-by-Step Solution

1
Identify the core objective of the required change management documentation.
The requirement is to specify how to revert modifications if performance degrades after implementation.
Risk management policies require explicit backout plans before executing production configuration changes.
2
Evaluate the documentation types against the defined requirement.
A rollback plan directly details the criteria, commands, and sequence needed to return to the baseline configuration.
Rollback plans safeguard network operations by ensuring immediate recovery paths during failed implementations.
