A company has two routing instances on a single router: 'Corp' and 'Guest'. Users in the 'Guest' network need to reach a server that is only reachable via a route in the 'Corp' instance. The administrator wants to leak only the specific route to the server into the 'Guest' instance, without leaking any other routes. What is the most appropriate method?

Change the 'Guest' instance-type to 'forwarding' to inherit routes.

Configure a static route in 'Guest' pointing to the next-hop in 'Corp'.

Use a rib-group to copy all routes from 'Corp' into 'Guest'.

Use a routing policy with a prefix-list to export the specific route from 'Corp' into 'Guest'.

What is the primary purpose of a routing instance in Junos OS?

To provide a backup routing table that is used only when the primary table fails

To combine multiple routing tables into a single table for simplified management

To store the routing table in a database for offline analysis

To create a separate routing table and forwarding table for a set of interfaces and protocols

An enterprise is deploying a new service that requires traffic from a specific interface to be forwarded based on a separate routing table, while the rest of the router continues to use the main routing table. The traffic must be selected based on source address, not by the destination. Which routing instance type and configuration method should be used?

Configure a forwarding instance and use a firewall filter to direct matching traffic into it.

Configure a virtual-router instance and import routes from the main table using rib-groups.

Configure a VRF instance and apply it to the interface using the 'routing-instance' statement.

Configure a non-forwarding instance and use policy to redirect traffic.

An administrator has two routing instances, 'A' and 'B'. The administrator wants to leak routes from 'A' to 'B' using a rib-group. The rib-group is configured and applied to the 'A' instance's routing options. However, the routes are not appearing in 'B'. What is a likely reason?

The rib-group is not a valid method for leaking routes between instances.

The rib-group name is misspelled or the import policy is missing.

The rib-group must be applied to the 'B' instance's routing options as well.

The rib-group was applied to the wrong instance; it should be applied to 'B'.
