After configuring filter-based forwarding on a Junos router, an administrator wants to confirm that traffic from a specific source is being forwarded to the correct routing instance. Which command should they use to see the routes in that routing instance?

show firewall filter fbf-filter

A network engineer needs to forward traffic from a specific source subnet to a different routing table on a Junos device. The device currently uses a single routing instance for all traffic. The engineer wants to avoid changing the existing routing configuration. Which feature should be used?

Virtual routing and forwarding (VRF)

When verifying FBF, what does the 'show firewall' command output indicate?

The list of interfaces to which the filter is applied.

The next-hop IP address for packets that match the filter.

The routing table of the routing instance specified in the filter's action.

The number of packets that matched each filter term, which can confirm that traffic is being selected by the FBF filter.

A company wants to send traffic from a specific department's subnet to a dedicated internet connection for compliance reasons. The router is a Junos device. The administrator needs to implement this without affecting other traffic. Which approach should be used?

Use a static route for the department's subnet pointing to the dedicated connection.

Create a new VLAN for the department and configure a separate routing instance for that VLAN.

Apply a firewall filter that sets the next-hop for the department's traffic.

Configure filter-based forwarding to direct traffic from the department's subnet to a routing instance that uses the dedicated connection.

A service provider hosts multiple tenants on a single MX router. Tenant A must use a specific upstream transit provider for all traffic, while Tenant B uses a different transit provider. Both tenants share the same physical interface and the same IP subnet. The routing policy must be based on the source IP address. Which approach should the administrator use?

Configure a routing instance per tenant and apply a firewall filter with a 'then routing-instance' action to the shared interface.

Create a separate VLAN per tenant and apply a routing instance to each VLAN interface.

Apply a firewall filter with a 'then accept' action and rely on the default routing table for forwarding.

Use policy-based routing with a routing policy that sets the next-hop for each tenant.
