The correct answer is A. vPC. vPC extends Layer 2 between switches with active-active forwarding, supports high throughput, has fast failure convergence, and relies on data plane learning (MAC advertisement not dependent on control plane protocols).

Data Center Network Design

Question

Refer to the exhibit. An engineer is creating a new data center design for a customer. The design must support virtual applications, enhance network resilience, and meet these requirements:

  • Extend Layer 2 across all network segments to support endpoint

mobility.

  • Access switches will support up to 20 GB capacity for north-south and

east-west traffic.

  • Provide fast convergence during link failures.
  • MAC address advertisement will not depend on the control plane.

Which solution must the engineer include in the design between the access and distribution switches?
