Cloud Computing Fundamentals

A network engineer is designing a highly scalable network for multi-tenant cloud infrastructure. Which of the following solution-and-protocol combinations is best suited to provide effective segmentation and tenant isolation?

  • A Spanning Tree Protocol in a large switching fabric, each tenant will be mapped to individual VLAN IDs for segmentation.
  • B Layer 2 Tunneling Protocol version 3 over an IP network, tenant cloud flows will be mapped to individual tunnels.
  • C VXLAN encapsulation to provide cloud network segmentation and tenant isolation and BGP EVPN as the control plane.
  • D VXLAN encapsulation to provide cloud network segmentation and tenant isolation with "Flood and Learn" mode.
Explanation

VXLAN creates isolated overlay segments using VNIs, while BGP EVPN provides a scalable control plane for distributing MAC and IP reachability information. EVPN supports multitenancy and avoids the scalability limitations of a flood-and-learn VXLAN control plane.
