In an EVPN-VXLAN architecture, how do EVPN and VXLAN work together?

EVPN provides the data-plane encapsulation, and VXLAN provides the control plane

EVPN and VXLAN are independent technologies that do not interact

EVPN and VXLAN both operate in the data plane to forward traffic

EVPN provides the control plane, and VXLAN provides the data-plane encapsulation

A service provider is evaluating EVPN-VXLAN for a multi-tenant data center. They have a requirement to support 10,000 tenants, each with multiple VLANs. They are concerned about the scalability of the control plane. Which EVPN feature helps scale the number of MAC routes?

MAC mobility extended community

What is the primary purpose of VXLAN in a data center network?

To encrypt all traffic between data center switches

To replace the need for VLANs entirely

To extend Layer 2 segments over a Layer 3 network

To provide a routing protocol for the underlay network

A data center is deploying EVPN-VXLAN with a spine-and-leaf topology. The team wants to ensure that if a leaf switch fails, traffic is quickly rerouted without relying on STP. Which EVPN mechanism provides fast convergence and loop prevention?
