Question 180
At the Dartwood public agency, an aggregation edge fails to establish BGP because one neighbor configuration has the wrong remote autonomous system. Which ongoing control best prevents this issue from recurring?
Explanation
Correct Answer
The needed prevention is to validate peer parameters before routing policy deployments. It directly sustains the original change to correct the approved peer address remote AS and source connectivity then inspect session states. This result addresses the stated challenge at the Dartwood public agency.
Incorrect Answers
OSPF path selection follows its calculated metrics rather than business labels on ports. The offered alternative applies that mechanism: Review cost design after link-speed upgrades. The reported facts point to a different controlling condition: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.
The option states: Review rate thresholds against measured normal guest demand. The source describes its associated mechanism as: bursting guest traffic can consume resources needed for contracted business services. By contrast, the current situation is governed by: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. Choosing this alternative would leave the question’s specific recurrence control unresolved.
Review power utilization and supply redundancy as endpoints grow. This option is based on the following distinct technical behavior: total chassis PoE consumption can exceed available power when endpoints start together. The present question instead depends on this mechanism: BGP neighbors require compatible AS relationships and reachable transport before exchanging routes, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.
