Designing Cisco Data Center Infrastructure (DCID) — Question 154

An engineer needs to design a network solution for a client-server farm that uses a pair of Cisco Nexus 9000 Series Switches that are configured with vPCs. Each server must connect to both switches by using two network interfaces, and the switches must always initiate the negotiation with the server. Which mode should be enabled to ensure that traffic is forwarded from the server to a data center network?

Answer options

• A. auto PAgP
• B. active LACP
• C. auto LACP
• D. desirable PAgP

Correct answer: C

Explanation

The correct answer is 'auto LACP' because it allows the switch to initiate negotiations with the server while also supporting link aggregation. The other options, such as 'active LACP' and 'desirable PAgP', require the server to initiate the negotiation process, which does not meet the requirement specified in the question.
