An associate configured a serial connection on Router1 to use PPP with authentication. You execute the debug ppp negotiation command on the router and receive the following output:
Which of the following statements are true? (Choose all that apply.)
A. the credentials are being sent in clear text
B. the connection failed
C. the peer’s name is Router2
D. the authentication failed
Explanation:
The peer router’s name is Router2 and the authentication method is PAP, which transmits the credentials in clear text. The peer name can be seen in the following line of output:
*Mar 3 00:06:17.536: Se1/1 PAP: Authenticating peer ROUTER2
The authentication protocol used is seen in the following line of output:
*Mar 3 00:06:16.868: Se1/1 LCP: AuthProto PAP (0x0304C023)
The connection process and authentication process are two separate processes and in this case both succeeded. First the connection completed as indicated by the following line of output:
*Mar 3 00:06:17.260: Se1/1 LCP: State is Open
Then later the authentication succeeded, as indicated by this line at the end of the output:
*Mar 3 00:06:17.584: Se1/1 PPP: Phase is UP
