A network architect is comparing traditional VLAN-based designs with EVPN-VXLAN. The architect needs to justify the migration by highlighting a key scalability benefit. Which statement accurately describes a scalability advantage of EVPN-VXLAN?

It eliminates the need for IP addressing on the underlay.

It reduces the number of switches required in the fabric.

It supports up to 16 million Layer 2 segments, compared to 4094 VLANs.

It allows the use of STP for loop prevention.

Which statement correctly describes the role of EVPN in a VXLAN data center?

EVPN is a data-plane protocol that forwards Ethernet frames across the IP fabric

EVPN replaces the need for a physical underlay network in the data center

EVPN provides the MAC-in-UDP encapsulation used to forward traffic between VTEPs

EVPN uses BGP to exchange MAC and IP routes, enabling the control plane for VXLAN overlays

Which data center use case is a common driver for deploying EVPN-VXLAN?

Providing a single point of failure for network services

Workload mobility across the data center

Replacing the need for any physical switches

Eliminating the need for network monitoring

A network engineer is explaining VXLAN to a junior engineer. The junior engineer asks why VXLAN uses a 24-bit VNI field. What is the primary purpose of this field?

To specify the UDP source port for load balancing

To indicate the type of encapsulation used

To carry the VLAN ID of the original frame

To identify up to 16 million unique Layer 2 segments
