CCNA Question of the Week
With CHAP, how does a remote node respond to a challenge message?
- With a hash value
- With a return challenge
- With a plaintext password
- With an encrypted password
The correct answer is 1.
A remote node responds to a CHAP challenge with a hash value that is based on the stored password and the challenge message. The local router compares this response to its own calculation of the hash value; if they match, the remote node must have the correct password and authentication is successful. Otherwise, authentication fails.
