Question 680
The HPE AOS-CX switching case is: A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC. Select TWO: a corrective switching action and separate evidence that the correction worked. (Select TWO.)
Explanation
Correct Answers
The targeted correction for A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail. It reduces the risk that a remote switch with only the affected in-band route can become unreachable precisely when rollback is needed.
A separate operational validation for A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC is: An isolated test site restores console or OOB management and rolls back a failed uplink change without physical improvisation. It proves intended behavior instead of accepting configuration presence alone.
Incorrect Answers
This alternative concerns central firmware and group compliance rollouts; its associated risk is: A queued or blocked Central operation can leave some switches on old software while dashboards imply the deployment finished. The observed case A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC requires the more specific remote management emergency rollback and recovery access control. The targeted action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.
This alternative concerns switch configuration archive and baseline governance; its associated risk is: A configuration backup with no device/version identity can restore an incorrect VLAN or security baseline during a major outage. The observed case A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC requires the more specific remote management emergency rollback and recovery access control. The targeted action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.
This alternative concerns handoff documentation and operational runbook maintenance; its associated risk is: Unrecorded VLAN or peer-role changes can turn routine incidents into extended outages and make compliance review unreliable. The observed case A failover test shows the switch forwards client traffic but the central management VRF cannot reach the NOC requires the more specific remote management emergency rollback and recovery access control. The targeted action is: Maintain an approved OOB or alternate management access path and safe rollback instructions for switches whose in-band uplinks may fail.
