Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 28

An engineer must create data-link redundancy for the company's Cisco Wireless LAN Controller. The engineer has decided to configure LAG-based redundancy instead of port-based redundancy. Which three features of LAG-based redundancy influenced this decision? (Choose three.)

Answer options

• A. Packets are always sent out on the same port they are received on.
• B. All interface traffic passes as long as one port is up.
• C. The same port has multiple untagged dynamics interfaces.
• D. Interface connection to two separate nonstacked switches is available.
• E. Full bandwidth of all links is available.
• F. Ports are grouped into multiple LAGs.

Correct answer: A, B, E

Explanation

The correct answer includes features that emphasize the reliability and efficiency of LAG-based redundancy. Option A is correct because packets being sent out on the same port they are received helps maintain order. Option B highlights that traffic can continue as long as one port is operational, which is critical for redundancy. Option E is accurate as it indicates that the full bandwidth of all links can be utilized, unlike other options that do not provide the same level of performance or redundancy benefits.
