A network administrator is troubleshooting an EIGRP connection between RouterA, IP
address 10.1.2.1, and RouterB, IP address 10.1.2.2.
Given the debug output on RouterA, which two statements are true?

A.
RouterA received a hello packet with mismatched autonomous system numbers.

B.
RouterA received a hello packet with mismatched hello timers.

C.
RouterA received a hello packet with mismatched authentication parameters.

D.
RouterA received a hello packet with mismatched metric-calculation mechanisms.

E.
RouterA will form an adjacency with RouterB.

F.
RouterA will not form an adjacency with RouterB.

Explanation:
If the k-value mismatch occurs, Router A will never form an adjacency with Router B since it
is one of the basic requirements of adjacency. If you see the exhibit, Router A received
HELLO packet with a mismatched metric.
