D.
The interconnect gateway can reside on the super spine layer of a multi-POD data center.
Answers
Suggested answer: A, D

Explanation:

A) IBGP is recommended for VXLAN stitching overlays because it provides better scalability and stability within the same administrative domain, which is crucial for seamless EVPN-VXLAN stitching.

D) The interconnect gateway can indeed reside on the super spine layer of a multi-POD data center. This placement facilitates interconnectivity and scaling in large, distributed network architectures.

You are asked to deploy an Ethernet bridging design in a data center with the following criteria:

- routing must occur on the leaf devices.

- VTEPs must terminate on the leaf devices.

- facilitate inter-VLAN communication.

- lower latency with East-West traffic.

Which architecture should you use in this scenario?

A.
collapsed spine architecture
A.
collapsed spine architecture

Answers
D.
centrally-routed bridging architecture
D.
centrally-routed bridging architecture
Answers
Suggested answer: B

Explanation:

Edge-routed bridging architecture fits all the criteria: routing occurs on leaf devices, VTEPs terminate on the leaf devices, facilitates inter-VLAN communication, and provides lower latency for East-West traffic due to its distributed nature.

You are an architect for an enterprise organization that currently operates three data centers with plans to expand to five data centers in the next year. You already notice large amounts of BUM flooding and must control this issue before implementing the next two data centers.

Which feature would address this issue?

A.
type-5 routes

D.
VXLAN BUM traffic filter
Answers
Suggested answer: C

Explanation:

Mesh groups in EVPN environments can control BUM (Broadcast, Unknown unicast, Multicast) flooding. This is particularly useful in scenarios where the network is expanding, as it helps manage the flood of BUM traffic more efficiently.

You manage a data center with a 5-stage EVPN-VXLAN IP fabric. You notice that there are suboptimal paths used between the leaf and spine as well as the spine and super spine. What is one way to solve this issue?

D.
Configure the leaf layer so that all leaf devices share the same ASN.
Answers
Suggested answer: C

Explanation:

By configuring all spines in a POD to share the same ASN, it simplifies the BGP routing and ensures that more optimal paths are used in a 5-stage EVPN-VXLAN IP fabric.
