200-301 · Question #597
Refer to the exhibit. Which network prefix was learned via EIGRP?
The correct answer is B. 192.168.2.0/24. The EIGRP learned network prefix can be identified by the 'D' code in the show ip route command output, which signifies a route discovered via the Enhanced Interior Gateway Routing Protocol.

Why each option
The EIGRP learned network prefix can be identified by the 'D' code in the `show ip route` command output, which signifies a route discovered via the Enhanced Interior Gateway Routing Protocol.
The routing table shows `C 172.16.0.0/16`, where 'C' indicates a directly connected network, not an EIGRP learned route.
The routing table output shows `D 192.168.2.0/24 [90/30720]`, where 'D' is the administrative code used to denote routes learned via EIGRP. The subsequent metrics `[90/30720]` confirm it is an internal EIGRP route, making 192.168.2.0/24 the correct answer.
The routing table shows `S 207.165.200.0/24`, where 'S' indicates a static route, not an EIGRP learned route.
The routing table shows `C 192.168.1.0/24`, where 'C' indicates a directly connected network, not an EIGRP learned route.
