A Junos router is configured with a routing instance named 'ENG' of type 'virtual-router'. The administrator wants to verify that the instance is correctly set up and that the interface ge-0/0/3.0 is bound to it. Which command will show the routing table for the 'ENG' instance?

show interfaces ge-0/0/3.0 extensive

show configuration routing-instances ENG

In Junos OS, what is the relationship between a routing zone and a routing instance?

They are two names for the same configuration element

A routing zone is a type of routing instance

They are independent and have no relation

A routing instance is a type of routing zone

A service provider is deploying a new MPLS L3VPN service in a Junos MX series router. The customer requires that their production and development environments be isolated at Layer 3, with separate routing tables. The router will use BGP to exchange VPN routes with the PE router. Which configuration element is REQUIRED to ensure the customer's two environments are treated as distinct VPNs by the provider's BGP signaling?

Applying a firewall filter to the customer-facing interface to block inter-VRF traffic.

Placing both environments in the same routing instance but using different import policies.

Configuring a separate routing instance of type 'forwarding' for each environment.

Assigning a unique route distinguisher (RD) to each VRF instance.

A service provider is configuring a new VRF for a customer on a Junos PE router. The customer requires that only routes from a specific BGP community are imported into the VRF. Which configuration element is used to control which routes are accepted into the VRF's routing table?

The VRF's routing protocol configuration (e.g., OSPF).

The route target (RT) in the VRF's import policy.

The interface assignment in the VRF's configuration.

The route distinguisher (RD) in the VRF's configuration.

Which configuration statement assigns an interface to a routing zone (routing instance) in Junos OS?

set policy-options policy-statement ZONE1 term 1 from interface ge-0/0/1.0

set interfaces ge-0/0/1 unit 0 family inet vrf ZONE1

set routing-instances ZONE1 interface ge-0/0/1.0

set interfaces ge-0/0/1 unit 0 family inet address 192.0.2.1/24
