Refer to the exhibit. When you apply these configurations to R1 and R2.
Which two effects occur? (Choose two)
A. The 172.16.1.1 network is reachable via OSPF on R1
B. R1 authenticates using the username Cisco
C. R1 and R2 successfully authenticates using CHAP
D. Authentication between R1 and R2 fails.
E. R1 and R2 authentications using PAP
I think it was a poorly written question.
Certainly D is correct, but if the 2 devices CANNOT pass authentication phase, then all other options would be immediately wrong. So there are no 2 correct options as it is.
Now, If the question requests 2 options, option B is probably badly written. It should say: ” R1 TRIES to authenticate…”.
By saying “authenticates”, it implies R1 was successfully on the authentication, which contradicts D.
