Question 300
At the Westhaven data center, a data center switch becomes unstable and system logs report abnormal fan and temperature sensors. Which ongoing control best prevents this issue from recurring?
Explanation
Correct Answer
After implementation, the team should monitor thermal events and cooling redundancy in facilities alerts as the appropriate recurring safeguard against the identified issue. This result addresses the stated challenge at the Westhaven data center.
Incorrect Answers
a misassigned access interface forwards untagged frames in the wrong broadcast domain. The offered alternative applies that mechanism: Review per-port templates and physical labeling on access moves. The reported facts point to a different controlling condition: overtemperature or failed cooling hardware can cause throttling and shutdown independent of routing configuration, rather than merely a monitoring or presentation issue. The alternative does not directly settle the required recurrence control.
Test VSX failure scenarios and peer link monitoring after maintenance. Its technical scope is explained by: loss of VSX coordination requires interpreting split and operational state rather than blindly bouncing all links, the required evidence must show that a controlled repair restores VSX peer health and downstream multi-chassis aggregation. In this question, the decisive issue is: overtemperature or failed cooling hardware can cause throttling and shutdown independent of routing configuration, rather than merely a monitoring or presentation issue. That is why the offered option is not the most direct recurrence control.
Audit VRF route-policy changes against the network access matrix. This option is based on the following distinct technical behavior: a poorly scoped route import can undermine segmentation without changing physical VLANs, the required evidence must show that the contractor reaches only approved destinations and the private network is no longer routable. The present question instead depends on this mechanism: overtemperature or failed cooling hardware can cause throttling and shutdown independent of routing configuration, rather than merely a monitoring or presentation issue. That difference matters for the requested recurrence control.
