CCNA Question of the Week

With CHAP, how does a remote node respond to a challenge message?

  1. With a hash value
  2. With a return challenge
  3. With a plaintext password
  4. 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.
