Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 68

To increase total throughput and redundancy on the links between the wireless controller and switch, the customer enabled LAG on the wireless controller.
Which EtherChannel mode must be configured on the switch to allow the WLC to connect?

Answer options

• A. Active
• B. Passive
• C. On
• D. Auto

Correct answer: C

Explanation

The correct answer is C, 'On', because this mode forces the EtherChannel to be active without any negotiation, which is necessary when LAG is enabled on the wireless controller. Options A and B rely on negotiation to form an EtherChannel, which would not work in this scenario. Option D, 'Auto', is also a negotiation mode and would not establish the connection as required.
