CCNA: Cisco Certified Network Associate — Question 614

What is a reason to implement LAG on a Cisco WLC?

Answer options

• A. Allow for stateful failover between WLCs.
• B. Increase security by encrypting management frames.
• C. Increase the available throughput on the link.
• D. Enable the connected switch ports to use different Layer 2 configurations.

Correct answer: C

Explanation

The correct answer is C, as implementing LAG (Link Aggregation Group) combines multiple physical links to increase bandwidth and improve throughput. Options A, B, and D do not directly relate to the primary purpose of LAG, which is to enhance link capacity rather than provide failover, security, or configuration flexibility.
