CCDE: Cisco Certified Design Expert (Practical) — Question 47

Company XYZ wants to redesign the Layer 2 part of their network and wants to use all available uplinks for increased performance. They also want to have end host reachability supporting conversational learning. However, due to design constraints, they cannot implement port-channel on the uplinks. Which other technique can be used to make sure the uplinks are in active/active state?

Answer options

• A. TRILL
• B. LISP
• C. MSTP
• D. switch stack

Correct answer: A

Explanation

The correct answer is TRILL, which allows for multiple active paths in a Layer 2 network while supporting features like load balancing and loop prevention. LISP and MSTP do not provide the same capabilities for utilizing multiple uplinks actively, and a switch stack does not inherently enable the same level of link utilization across uplinks.
