Which Junos operational command displays the routing table for a specific VRF instance?

show configuration routing-instances VRF-A

A Junos device is configured with a routing instance of type 'virtual-router'. The network administrator wants to ensure that traffic from interface ge-0/0/1.0 is routed using the routing table of this instance, while traffic from ge-0/0/2.0 uses the default routing table. What must be configured to achieve this?

Create a firewall filter that redirects traffic from ge-0/0/1.0 to the routing instance.

Configure ge-0/0/1.0 with a VRRP group that references the routing instance.

Assign ge-0/0/1.0 to the routing instance in the 'interfaces' hierarchy.

Define a routing policy that matches ge-0/0/1.0 and sets the next-hop to the instance's routing table.

Which statement accurately describes the forwarding table in a VRF instance?

It is used to make forwarding decisions for packets arriving on interfaces assigned to that VRF

It is shared among all VRFs to optimize memory usage

It is only used for multicast traffic

It is identical to the routing table and does not need to be maintained separately

What is the purpose of using a logical tunnel (lt) interface for route leaking between VRFs?

To connect two VRFs so that traffic can be forwarded between them

To encrypt traffic between VRFs

To provide a backup path between VRFs

Which method can be used to leak routes between VRFs without using a logical tunnel?

Using firewall filters to copy routes

Using the 'set protocols bgp leak' command

Using routing policies with the 'next-table' action

Using static routes with a next-hop of 'discard'
