Question 400
At the Birchhaven airport network, campus access switches develop inconsistent VLAN and AAA settings because each engineer uses personal commands. Which setting or practice should be reviewed in future?
Explanation
Correct Answer
For the Birchhaven airport network, this maintenance action preserves the fix: compare switches to the baseline after every change window. It should be revisited as the workload evolves.
Incorrect Answers
poor ownership records delay approvals and root cause investigation after changes. The offered alternative applies that mechanism: Review inventory accuracy as network sites and responsibilities change. The reported facts point to a different controlling condition: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. The alternative does not directly settle the required recurrence control.
Check cooling and hardware alarms during routine site walks. Its technical scope is explained by: thermal faults can destabilize forwarding independent of network traffic congestion. In this question, the decisive issue is: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. That is why the offered option is not the most direct recurrence control.
The option states: Trend multicast membership and RPF failure counts. The source describes its associated mechanism as: multicast delivery depends on its own control and forwarding tables in addition to unicast routing, the required evidence must show that a monitored subscription test shows receiver memberships and source packets on the approved interface. By contrast, the current situation is governed by: configuration drift increases security exposure and incident uncertainty between otherwise similar sites. Choosing this alternative would leave the question’s specific recurrence control unresolved.
