Question 1
At South Science Wing, a VSX pair has healthy LAGs but keepalive routes accidentally transit an unstable user VLAN. What operational rule should remain in place for later changes?
Explanation
Correct Answer
For South Science Wing, the decisive mechanism is VSX keepalive separation. The VSX keepalive helps distinguish peer failure from ISL failure. Keep keepalive routing isolated from routine campus policy edits is an enduring limitation on the operational risk, not simply a one-time passing test.
Incorrect Answers
This is relevant to Loop protection, where loop detection complements STP by containing accidental edge loops In the South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is the VSX keepalive helps distinguish peer failure from ISL failure
This is relevant to VRRP redundant gateway, where VRRP supplies virtual first-hop gateway failover between eligible routing peers In the South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is the VSX keepalive helps distinguish peer failure from ISL failure
This is relevant to AOS 10 gateway cluster, where an AOS 10 gateway cluster improves tunneled WLAN availability but still needs correct forwarding and policy In the South Science Wing case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is the VSX keepalive helps distinguish peer failure from ISL failure
