The forwarding table is used by the RE to select the best route.

Answer(s): A,D

Explanation:

The routing table and forwarding table play distinct roles in a Junos OS device. The correct answers are A and D. The routing table (A) is used by the Routing Engine (RE) to select the best route among all the learned routes, while the routing table (D) stores all routes and prefixes learned from all routing protocols. The forwarding table, in contrast, contains only the active routes chosen by the RE and is used by the Packet Forwarding Engine for actual packet forwarding.

QUESTION: 8

An administrator configures a router's interface with an IPv4 address and subnet mask. The administrator also confirms that this interface is in an up state. In this scenario, which two route types are created on the local router? (Choose two.)

a static route
a local route
a dynamic route
a direct route

Answer(s): B,D

Explanation:

When an interface on a router is configured with an IPv4 address and is in an up state, two types of routes are automatically created in the routing table: a local route and a direct route, making B and D the correct answers. The local route represents the interface's IP address itself, indicating that the router can directly receive packets addressed to this IP. The direct route represents the subnet or network segment to which the interface is connected, indicating that the router can directly forward packets to destinations within this subnet.
