In an EVPN-VXLAN environment, how does a VTEP learn MAC addresses from remote VTEPs?

By flooding traffic to all VTEPs and observing source MAC addresses

By sending ARP requests to the remote VTEP

By querying the MAC-VRF database

A network team wants to prevent a specific leaf switch from receiving Type-2 routes for a particular MAC address in an EVPN-VXLAN fabric. The leaf switch is a BGP peer with the route reflector. What is the most appropriate way to achieve this?

Change the VXLAN VNI on the leaf switch

Configure a route policy on the route reflector to filter the Type-2 route outbound to the leaf switch

Change the route distinguisher (RD) on the leaf switch

Disable MAC learning on the leaf switch

A host with a static MAC address moves between two leaf switches in an EVPN-VXLAN fabric. The network team notices that traffic to the host is still being forwarded to the old leaf switch. What is the most likely cause of this issue?

The MAC aging timer on the old leaf switch is too short

The MAC mobility sequence number was not incremented on the new leaf switch

The VXLAN VNI was changed on the old leaf switch

The route target (RT) was changed on the new leaf switch

What is the function of a VXLAN gateway when it receives a frame from a traditional VLAN destined for a host in a VXLAN overlay?

It encapsulates the Ethernet frame in a VXLAN header and forwards it over the overlay

It decapsulates the VXLAN header and forwards the frame as a standard Ethernet frame

It translates the VLAN tag to a VXLAN VNI and forwards the frame without encapsulation

It routes the frame based on the destination IP address

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 27 practice questions to prepare you well beyond it.
