What is the purpose of a routing instance in Junos?

To combine multiple physical interfaces into a single logical interface for redundancy

To filter traffic based on source and destination IP addresses

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

To prioritize certain types of traffic over others

What is a common method to route traffic between two different routing instances on the same Junos device?

Using a physical cable between two ports

Using a static route in the global routing table

Using a logical tunnel (lt) interface

Using a firewall filter to redirect traffic

Within a VRF, how is the next hop for a tenant route resolved?

Using the routing table of the VRF, which contains routes learned via the VRF's configured protocols and interfaces

Using the global routing table's next-hop information

Using the route distinguisher to determine the next hop

Using the export policy to select the next hop

When troubleshooting a missing route in a VRF, which command would you use to verify that the correct interfaces are assigned to the routing instance?

show configuration routing-instances

A service provider is troubleshooting a route leakage issue between two tenants' VRFs. Tenant A's VRF is importing routes from Tenant B's VRF, which should not happen. The provider has verified that the route targets are correctly configured and unique per tenant. What is the most likely cause of the unintended route import?

The VRF export policy is incorrectly setting the route target to a shared value.

The routing instance type is incorrect, causing routes to be shared by default.

The route distinguisher is incorrectly configured, causing route overlap.

The VRF import policy is too permissive, matching a broader route target range than intended.
