Designing Cisco Data Center Infrastructure (DCID) — Question 168

A network engineer designs a Cisco Nexus data center network for a client-server farm using a pair of Nexus 9000 Series Switches in a vPC setup. Each server connects with two interfaces to both Nexus switches. The Nexus switches must always initiate the negotiation with the server.

Which feature should be used in this design to ensure traffic is forwarded from the server to the data center network?

Answer options

Correct answer: C

Explanation

The correct answer is C, LACP mode active, because it enables the switches to actively initiate the negotiation process for link aggregation with the servers, ensuring proper traffic flow. Options A and D involve PAgP, which is not applicable in this context since the negotiation must be initiated by the Nexus switches. Option B, LACP mode auto, would only respond to negotiation requests, making it unsuitable for the requirement of active initiation.
