A network administrator is explaining to a colleague how Junos handles packet forwarding. The colleague asks: 'When a packet arrives, which table does the router consult to determine the outgoing interface?' What is the correct answer?

The routing table, because it contains all learned routes.

The forwarding table, because it contains the active routes with next-hop information.

The ARP table, because it maps IP addresses to MAC addresses.

The configuration database, because it stores interface settings.

A router has two routes to 192.168.1.0/24: one from OSPF with a preference of 10 and a metric of 100, and one from RIP with a preference of 100 and a metric of 4. Which route will be installed in the forwarding table?

Both routes, because they are equal-cost paths.

The RIP route, because it has a lower metric.

The OSPF route, because it has a lower preference.

Neither route, because they are from different protocols.

What is the primary role of the forwarding table in a Junos device?

To enable the Packet Forwarding Engine to make fast forwarding decisions for incoming packets.

To store all routing protocol information and maintain the routing database.

To store the configuration of all interfaces and their IP addresses.

To provide a backup copy of the routing table in case of a Routing Engine failure.
