Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 146

A network engineer must design a new wireless solution for a company, but the budget can only stretch to include a single Cisco 9800-40 WLC. The company requires high availability between the WLC and the core switch in the event of a cable failure. The WLC must dynamically manage port redundancy and perform load balancing between APs transparently. Which design approach must the engineer take to meet the requirements?

Answer options

• A. LAG
• B. Multi-LAG
• C. LACP
• D. PAgP

Correct answer: A

Explanation

The correct answer is A, LAG (Link Aggregation Group), which allows for multiple connections to be bundled together, providing redundancy and load balancing. Multi-LAG is unnecessary since only a single WLC is being used. LACP and PAgP are protocols for link aggregation but do not directly address the requirements of managing redundancy and load balancing as efficiently in this scenario.
