A systems administrator is scheduled to install a firmware update on the company's edge firewall during an approved maintenance window. The change-control policy states that all documented business processes must be completed before implementation. Which document will specify the exact steps for returning the firewall to its previous configuration if the update unexpectedly disrupts connectivity?
A rollback plan is created during change management to detail the exact procedure for restoring a device or service to its known-good state if the new change fails. While sandbox testing, risk analysis, and end-user acceptance are also part of the overall process, only the rollback plan contains the step-by-step instructions to undo the change and minimize downtime. Therefore, the rollback plan is the required document in this scenario.
