A service provider wants to offer EVPN-VXLAN services to two customers. Each customer has multiple sites, and the provider needs to ensure that routes from one customer are never leaked to the other. What is the best practice?

Use unique route distinguishers for each customer and rely on them for isolation

Use unique route targets for each customer and configure VRF import/export policies accordingly

Use the same bridge domain for both customers but different EVIs

Use the same route targets for both customers but different route distinguishers

How does an Ethernet segment (ES) enable multi-homing in an EVPN fabric?

It allows a customer device to connect to multiple PE devices using the same ESI, providing redundancy and load balancing.

It enables the use of multiple VNIs for a single broadcast domain.

It allows a single PE to connect to multiple customer devices using different ESIs.

It provides Layer 3 routing between different EVIs.

A network architect is designing an EVPN-VXLAN fabric with multiple tenants. Each tenant has its own EVI. The architect wants to ensure that routes from one tenant are not leaked to another. What is the most important configuration to achieve this?

Use unique bridge domains for each tenant's EVI

Use unique route targets for each tenant's EVI

Use unique Ethernet segments for each tenant's EVI

Use unique route distinguishers for each tenant's EVI

What is the primary difference between a route target (RT) and a VRF import/export policy in EVPN?

RTs are used for Layer 3 routing, while VRF import/export policies are used for Layer 2 forwarding.

RTs are used only on spine devices, while VRF import/export policies are used only on leaf devices.

RTs are used to identify the EVI, while VRF import/export policies are used to identify the VNI.

RTs are BGP extended communities used to control route advertisement, while VRF import/export policies are local configuration that uses RTs to filter routes.

What is the role of a bridge domain in an EVPN-VXLAN fabric?

It performs Layer 3 routing between different EVIs.

It establishes BGP EVPN sessions between leaf devices.

It encapsulates traffic in VXLAN headers.

It provides Layer 2 forwarding within the fabric by mapping to an EVI.

EVPN Control Plane JN0-481 Practice Questions (Page 1)

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.
