Question 400
An HPE Aruba Networking engineer faces this wired-network scenario: A VSX pair loses downstream LAG forwarding after an ISL interruption. Which implementation action BEST addresses the requirement?
Explanation
Correct Answer
VSX peer split handling responds differently to ISL versus keepalive failures. The targeted implementation is to identify ISL and keepalive states before modifying the peer's forwarding behavior. The deployment succeeds when vSX peer health diagnoses the safe failover state under the observed fault.
Incorrect Answers
This implementation choice fits a different situation: A printer in VLAN 30 works locally but cannot reach a print server over an uplink. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify ISL and keepalive states before modifying the peer's forwarding behavior.
This implementation choice fits a different situation: An OSPF neighbor remains down despite successful ICMP pings between peers. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify ISL and keepalive states before modifying the peer's forwarding behavior.
This implementation choice fits a different situation: A user host has an IP address in the wrong subnet and cannot reach its gateway. It does not resolve the stated failure mode. For this case, the decisive implementation choice is to identify ISL and keepalive states before modifying the peer's forwarding behavior.
