Which type of routes are held in Inet.0?

The correct answer is C. IP version 4 unicast routes. The inet.0 routing table in Junos OS is the primary table specifically designated for storing and managing all IPv4 unicast routes. It contains the best routes learned from various routing protocols or static configurations for reaching IPv4 destinations.

Why each option

The `inet.0` routing table in Junos OS is the primary table specifically designated for storing and managing all IPv4 unicast routes. It contains the best routes learned from various routing protocols or static configurations for reaching IPv4 destinations.

Amulticast and unicast IPv4 routes

While `inet.0` holds unicast IPv4 routes, multicast routes are typically held in `inet.1` or `inet.2`.

BARP tables and MAC reachability

ARP tables and MAC reachability are not stored in the `inet.0` routing table; they are typically found in the Ethernet switching table or ARP cache.

CIP version 4 unicast routesCorrect

`inet.0` is the default routing table in Junos OS that stores all active IPv4 unicast routes, which are used for forwarding IPv4 packets to their destinations.

DIP version 6 and IP version 4 routes

`inet.0` is specifically for IPv4 unicast routes; IPv6 routes are stored in `inet6.0`.
