Question 340
At the Elmhurst manufacturing plant, a VSX distribution pair loses inter switch communication and downstream forwarding becomes inconsistent. Which setting or practice should be reviewed in future?
Explanation
Correct Answer
The team should test VSX failure scenarios and peer link monitoring after maintenance. That recurring practice targets the same weakness, namely that loss of VSX coordination requires interpreting split and operational state rather than blindly bouncing all links. This result addresses the stated challenge at the Elmhurst manufacturing plant.
Incorrect Answers
a Layer 3 path can pass static traffic while DHCP assignment fails separately. The offered alternative applies that mechanism: Monitor DHCP relay and scope depletion alerts. The reported facts point to a different controlling condition: 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. The alternative does not directly settle the required recurrence control.
Track IGMP group and querier health as media demand grows. Its technical scope is explained by: without valid membership tracking multicast can be flooded to unrelated ports. In this question, the decisive issue is: 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. That is why the offered option is not the most direct recurrence control.
Track endpoint NIC and driver compatibility after image updates. This option is based on the following distinct technical behavior: an endpoint driver defect can cause retries or negotiation issues without a switch fault. The present question instead depends on this mechanism: 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. That difference matters for the requested recurrence control.
