CCDE: Cisco Certified Design Expert (Practical) — Question 74

Company XYZ wants design recommendations for Layer 2 redundancy (using Layer 2 technologies). The company wants to prioritize flexibility and scalability elements in the new design. Which two technologies help meet these requirements? (Choose two.)

Answer options

• A. Configure DHCP snooping on the switches
• B. Use switch clustering at the distribution layer where possible
• C. Use Unidirectional Link Detection
• D. Avoid stretching VLANs across switches
• E. Use root guard

Correct answer: B, E

Explanation

Using switch clustering at the distribution layer allows for increased flexibility and scalability by enabling multiple switches to operate as a single unit, thus enhancing redundancy. Root guard helps maintain the stability of the spanning tree by preventing unwanted switches from becoming the root, contributing to a reliable Layer 2 design. The other options either do not directly enhance redundancy or may complicate the network design.
