Which EVPN route type is used to advertise MAC addresses and their associated IP addresses?

Route type 1 (Ethernet auto-discovery route)

Route type 3 (Inclusive multicast Ethernet tag route)

Route type 2 (MAC/IP advertisement route)

What is the purpose of the Ethernet segment identifier (ESI) in EVPN?

It determines the BGP next hop for EVPN routes.

It uniquely identifies an Ethernet segment shared by multiple PE devices.

It identifies the VXLAN VNI used for the segment.

It assigns a MAC address to the customer edge device.

Which statement correctly describes the relationship between an EVI and a VXLAN network identifier (VNI)?

A VNI is mapped to multiple EVIs to allow inter-domain routing.

An EVI is mapped to a VNI to associate the EVPN domain with the VXLAN data plane segment.

The EVI replaces the VNI in VXLAN encapsulation.

The EVI and VNI are interchangeable terms for the same construct.

An EVPN-VXLAN fabric has a multi-homed server. The operator wants to ensure that when a leaf fails, the remaining leaf can quickly take over forwarding for the server's MAC. Which EVPN route type is used to signal this?

Route Type 1 (Ethernet Auto-Discovery Route)

Route Type 2 (MAC/IP Advertisement Route)

Route Type 3 (Inclusive Multicast Route)

An EVPN-VXLAN fabric uses a single BGP session between route reflectors and leaves. The operator notices that MAC routes from different EVIs are being treated as the same route, causing conflicts. What is the most likely cause?

The route targets are not unique per EVI

The bridge domains are not mapped correctly

The route distinguishers are not unique per EVI

The Ethernet segment identifiers are duplicated

EVPN Control Plane JN0-481 Practice Questions (Page 3)

Part of the Data Center Architectures (IP Fabrics, EVPN-VXLAN) domain, which makes up ~5% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~2–3 in this domain), expect 1–1 from this objective — we provide 18 practice questions to prepare you well beyond it.
