QuestionQ218

Network Design

A company plans to enhance segmentation of its data center network to isolate traffic for different clients across multiple areas of the facility. The solution must be highly scalable and deliver flexible traffic isolation as the number of clients grows. Which action should be taken to best satisfy these requirements?

  • A Implement VXLAN with IP-based VLAN segmentation to provide separation for each client while using standard Layer 3 routing.
  • B Enable VXLAN with Border Gateway Protocol EVPN to provide separation and granular routing control.
  • C Configure VXLAN Multi-Tenant mode to segregate traffic by using different network identifiers.
  • D Implement VRF-Lite to segment traffic between different network environments.
Explanation

VXLAN with BGP EVPN provides a scalable control plane for VXLAN overlays, supports inherent multi-tenancy, and enables both Layer 2 bridging and Layer 3 routing between segments. BGP-based route distribution also provides granular routing-policy control, making it well suited to scalable client isolation across a data center.
