CompTIA Network+ N10-006 Q149

B. Stakeholder notification
C. Impact analysis
D. Rollback procedure

Correct Answer: D
Section: Industry standards, practices, and network theory

A rollback procedure is something that should be documented in a change management document. In this question, the network technician has made a change during a maintenance window. The change has not worked so the technician needs to ‘undo’ the change he made to revert the system back to its previous state. The network technician can then investigate why the change has not worked as expected.
The rollback procedure is the list of steps required to undo the changes made to the system.
