What is the primary purpose of a route distinguisher (RD) in EVPN?

It provides the VXLAN encapsulation format.

It filters routes based on the VNI.

It makes routes unique across different EVIs and VRFs.

It identifies the next hop for EVPN routes.

A two-leaf EVPN-VXLAN fabric uses a single aggregated Ethernet link from a server to both leaves for redundancy. The operator wants to ensure that if one leaf fails, the other leaf can still forward traffic for the server's MAC address. Which EVPN mechanism is essential for this?

Configuring the same Ethernet Segment Identifier (ESI) on both leaves for the server's link

Using a different bridge domain on each leaf for the server's VLAN

Assigning a unique ESI to each leaf for the server's link

Enabling Route Type 5 for the server's IP address

An EVPN-VXLAN fabric has multiple EVIs and VRFs. The operator notices that MAC routes from different EVIs are being incorrectly imported into the same VRF. What is the most likely cause and what should be checked?

The bridge domains are not mapped correctly to the EVIs

The route distinguishers are not unique per EVI, causing route collisions

The Ethernet segment identifiers are duplicated across EVIs

The route targets are not unique per EVI, causing routes from different EVIs to be imported into the same VRF

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.
