The correct answer is B. Requiring all network changes include updating the network diagrams. To prevent mismatches between physical network infrastructure and documentation after a change window, it is crucial to enforce a policy that mandates updating network diagrams as an integral part of every network change process.
Question
During a network outage, a technician discovers a new network switch that was not listed in the support documentation. The switch was installed during a recent change window when a new office was added to the environment. Which of the following would most likely prevent this type of mismatch after next month's change window?
Options
- APerforming annual network topology reviews
- BRequiring all network changes include updating the network diagrams
- CAllowing network changes once per year
- DRoutinely backing up switch configuration files

Why each option
To prevent mismatches between physical network infrastructure and documentation after a change window, it is crucial to enforce a policy that mandates updating network diagrams as an integral part of every network change process.
Annual network topology reviews are important but less frequent, meaning discrepancies could exist for a significant period before being identified.
Requiring all network changes to include updating network diagrams directly addresses the issue of documentation being out of sync with the physical infrastructure, ensuring that support documentation accurately reflects the current network topology. This makes documentation a mandatory step in the change management process.
Allowing network changes only once per year is impractical for most environments and would severely hinder operational flexibility and responsiveness.
Routinely backing up switch configuration files is good for recovery and auditing but does not directly ensure that network documentation like topology diagrams are updated.
