Designing Cisco Data Center Infrastructure (DCID) — Question 158

An engineer finishes the initial set up of a VXLAN EVPN network. The engineer is asked to plan for external connectivity that supports redundancy and extends multiple virtual routing and forwarding domains. The requirement is to use the same default gateway addressing across all leaf switches that belong to the VXLAN network.

Which two solutions must be used to meet these requirements? (Choose two.)

Answer options

• A. Distributed Anycast Gateway
• B. VRF-Lite
• C. Inter-Site Network
• D. DC Interconnect
• E. Spanning Tree Protocol

Correct answer: A, B

Explanation

The Distributed Anycast Gateway allows multiple leaf switches to share the same default gateway IP, ensuring redundancy and simplifying gateway management. VRF-Lite is also necessary as it enables the segmentation of traffic across different virtual routing and forwarding instances, which is essential for extending multiple domains. The other options do not provide the required functionality for default gateway addressing or do not support the necessary redundancy features.
