CCNA: Cisco Certified Network Associate — Question 860

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

Answer options

• A. to increase security and encrypt management frames
• B. to enable connected switch ports to failover and use different VLANs
• C. to provide link redundancy and load balancing
• D. to allow for stateful and link-state failover

Correct answer: C

Explanation

The correct answer is C because implementing Link Aggregation Group (LAG) allows multiple physical links to be combined into one logical link, ensuring redundancy and balancing the load across the links. The other options do not accurately reflect the primary purpose of LAG, which focuses on redundancy and load balancing rather than security, VLAN failover, or stateful failover.
