Question 310
At the Maplehaven manufacturing plant, an uplink BGP peer goes down after a firewall policy change but technicians reset routing before checking TCP connectivity. Which explanation best accounts for the concern?
Explanation
Correct Answer
The strongest explanation is that BGP cannot converge if the underlying connection or peer access is blocked. This accounts for the outcome and supports the action to verify transport reachability and peer authentication then restore the supported BGP neighbor session. This result addresses the stated challenge at the Maplehaven manufacturing plant.
Incorrect Answers
A poorly scoped route import can undermine segmentation without changing physical VLANs. This option is based on the following distinct technical behavior: a poorly scoped route import can undermine segmentation without changing physical VLANs, rather than merely a monitoring or presentation issue. The present question instead depends on this mechanism: it requires the team to monitor BGP transport and peer state after firewall updates. That difference matters for the requested root-cause explanation.
overtemperature or failed cooling hardware can cause throttling and shutdown independent of routing configuration, rather than merely a monitoring or presentation issue. The offered alternative applies that mechanism: Overtemperature or failed cooling hardware can cause throttling and shutdown independent of routing configuration. The reported facts point to a different controlling condition: it requires the team to monitor BGP transport and peer state after firewall updates. The alternative does not directly settle the required root-cause explanation.
An endpoint driver defect can cause retries or negotiation issues without a switch fault. In this question, the decisive issue is: it requires the team to monitor BGP transport and peer state after firewall updates. That is why the offered option is not the most direct root-cause explanation.
