A switch is configured as a VTEP and has a local VLAN 100 mapped to VNI 100100. A frame arrives on a port in VLAN 100 with a destination MAC that is known to be on a remote VTEP. What is the correct sequence of actions the VTEP performs?

Look up the destination MAC in the forwarding table, encapsulate the frame with VNI 100100 and the remote VTEP's IP, and send it via the underlay.

Decapsulate the frame and forward it to the local port.

Flood the frame to all local ports and all remote VTEPs in VNI 100100.

Route the frame based on the destination IP address.

A switch configured as a VTEP receives a VXLAN-encapsulated packet from the underlay. The destination UDP port is 4789, and the VNI matches a locally configured VNI. What is the next step the VTEP performs?

Drop the packet because the destination MAC is unknown.

Decapsulate the packet by removing the outer IP/UDP/VXLAN headers and forward the inner Ethernet frame on the associated local VLAN.

Re-encapsulate the packet with a new VNI and forward it to another VTEP.

Route the inner frame based on the destination IP address.

What is the primary purpose of VXLAN encapsulation?

To replace IP routing with a simpler Layer 2 forwarding mechanism

To compress Ethernet frames to reduce bandwidth usage

To extend Layer 2 networks across a Layer 3 underlay by encapsulating Ethernet frames in UDP/IP

To provide encryption for Layer 2 traffic between switches

An administrator is configuring VXLAN on a switch that connects to servers in VLAN 100 and VLAN 200. The switch will act as a VTEP and map each VLAN to a different VNI. What is the primary purpose of using distinct VNIs for each VLAN?

To allow the same MAC address to exist in both VLANs

To enable routing between VLAN 100 and VLAN 200 on the VTEP

To reduce the MTU requirement on the underlay

To isolate the Layer 2 broadcast domains of VLAN 100 and VLAN 200 across the underlay

In a BGP EVPN control plane, how do VTEPs discover each other?

By exchanging BGP EVPN routes that include VTEP IP addresses

By using DNS to resolve VTEP names

By sending multicast join messages

By flooding ARP requests across the underlay

Part of the Campus EVPN-VXLAN domain, which makes up ~11% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 32 practice questions to prepare you well beyond it.
