A service provider is offering DCI services to a customer. The customer has a legacy network that does not support VXLAN. The service provider wants to extend the customer's VLANs across the DCI without requiring the customer to upgrade their equipment. What is the most appropriate solution?

Use a Layer 3 gateway to route between the customer's VLAN and the VXLAN overlay.

Require the customer to deploy a VXLAN-capable switch at their site.

Configure the customer's switch to use VXLAN with a static VNI mapping.

Deploy a Layer 2 gateway at the DCI edge that terminates the VXLAN tunnel and presents a standard 802.1Q trunk to the customer's legacy switch.

What is the purpose of using EVPN Type-5 routes for inter-subnet routing across a DCI?

To discover VTEPs and establish VXLAN tunnels.

To advertise IP prefixes so that remote sites can route traffic to subnets located at other sites.

To provide redundancy for multihomed links.

To advertise MAC addresses for Layer 2 forwarding.

What is the function of a Layer 2 gateway at the DCI edge?

It extends Layer 2 VLANs between data centers by bridging traffic across the DCI.

It provides NAT between the data centers.

It routes traffic between different subnets at the DCI edge.

It encrypts traffic between data centers.

What is the purpose of a Route Distinguisher (RD) in EVPN for DCI?

To make EVPN routes unique across different VPNs or sites.

To specify the next hop for a route.

To control route import and export.

To identify the VNI for a route.

A network engineer is designing the underlay for a new EVPN-VXLAN DCI. The underlay will be a routed IP network using OSPF. The engineer is concerned about the size of the VXLAN packets and wants to ensure that the underlay can carry them without fragmentation. What is the minimum MTU that should be configured on the underlay interfaces?
