Correct Answer: BC
Router R3 is shown to have 'authentication-type password' and 'authentication-key', which implies it is using simple password authentication. However, on router R1, 'authentication-type password' is configured with 'message-digest-key', which is typically used for MD5 authentication. Since this mismatch in authentication key type between password and message-digest-key is likely causing the OSPF adjacency to fail, the correct answer is that Router R3 has the incorrect authentication key type.

Ranx01Option: C
Mar 25, 2021I think "C" is the correct answer. The authentication-type used for both R1 & R2 is "Simple Authentication" which does not require a message-digest-key as configured on R1 hence "Router R1 has the incorrect authentication key type" Answer C.
