Designing Cisco Data Center Infrastructure (DCID) — Question 27

What are two advantages of using Cisco vPC over traditional access layer designs? (Choose two.)

Answer options

• A. supports Layer 3 port channels
• B. disables spanning-tree
• C. no spanning-tree blocked ports
• D. uses all available uplink bandwidth
• E. maintains single control plane

Correct answer: C, D

Explanation

The correct answers, C and D, highlight that Cisco vPC eliminates the issue of blocked ports due to spanning-tree, allowing for optimal use of uplink bandwidth. Options A, B, and E are not advantages of vPC; A refers to a feature not unique to vPC, B is inaccurate as vPC still utilizes spanning-tree for redundancy, and E does not specifically apply to the advantages of vPC over traditional designs.
