A. B. C. D.AC
The inet.0 routing table is the default routing table in the Junos OS that is used for IP version 4 (IPv4) unicast traffic. Here are the two statements that are correct about the inet.0 routing table:
A. It stores information learned from routing protocols and other sources: The inet.0 routing table stores information learned from various sources such as routing protocols like OSPF, BGP, RIP, and static routes. The routing protocols advertise network reachability information to other routers, which is then stored in the inet.0 routing table. Other sources that can populate the inet.0 routing table include direct routes and aggregated routes.
C. It is used for populating the forwarding table: The inet.0 routing table is used to populate the forwarding table. The forwarding table is a hardware-based table that contains information on how to forward packets based on the destination address. When a packet arrives at a Junos OS device, the forwarding table is consulted to determine the egress interface and next hop to forward the packet. The entries in the forwarding table are created based on the information stored in the inet.0 routing table.
Therefore, options A and C are the correct statements about the inet.0 routing table.
B and D are incorrect. The forwarding policy is applied to packets after the forwarding table has determined the egress interface and next hop, so it is not used for populating the forwarding policy. The Ethernet switching table is used for forwarding Ethernet frames, not IP packets, so it is not related to the inet.0 routing table.
