Refer to the exhibit, which shows a truncated output of a real-time RADIUS debug.

Which two statements are true? (Choose two.)
A . The RADIUS server queried for authentication is located at IP address 172.25.188.164.
B . Authentication was unsuccessful.
C . The authentication scheme used was pop3.
D . Authentication was successful
E . Two-factor authentication was required.

Answer: AB

Explanation:

RADIUS Server IP Address:

The debug output shows that the RADIUS request was sent to the server at IP=172.25.188.164. This indicates that the RADIUS server being queried for authentication is indeed located at this IP address.

Authentication Result:

The debug output includes a line indicating the result for the RADIUS server: Result for radius svr ‘RadiusServer’ 172.25.188.164(0) is 0. A result code of 0 typically signifies that the authentication attempt was unsuccessful.

Authentication Scheme:

The debug output does not indicate that the authentication scheme used was pop3; it mentions using CHAP (Challenge Handshake Authentication Protocol).

Two-factor Authentication:

There is no indication in the debug output that two-factor authentication was required for this session.
