- B.
Logon request, challenge, encrypts value response, server, compare encrypted results, authorize or fail
- C.

- D.
Logon request, server, encrypts value response, challenge, compare encrypted results
Correct Answer
B. Logon request, challenge, encrypts value response, server, compare encrypted results, authorize or failExplanation
The initiator sends a logon request from the client to the server. The server sends a challenge back to the client. The challenge is encrypted and then sent back to the server. The server compares the value from the client and if the information matches, the server grants authorization. If the response fails, the session fails and the request phase starts over.Rate this question:

- 25.
Which of the following statements is true regarding the CHAP authentication system?
- A.
A certificate being handed from the server to the client once authentication has been established. If you have a pass, you can wander through the network. But limited access is allowed
- B.
If your token does not grant you access to certain information, that information will either not be displayed or your access will be denied. The authentication system creates a token every time a user or a session begins. At the completion of a session, the token is destroyed
- C.
The authentication process uses a Key Distribution Center (KDC) to orchestrate the entire process. The KDC authenticates the network. Principles can be users, programs or systems. The KDC provides a ticket to the network. Once this ticket is issued, it can be used to authenticate against other principles. This occurs authomatically when a request or service is performed by another network
- D.
The initiator sends a logon request from the client to the server. The server sends a challenge back to the client. The challenge is encrypted and then sent back to the server. The server compares the value from the client and if the information matches, the server grants authorization. If the response fails, the session fails and the request phase starts over
Correct Answer
D. The initiator sends a logon request from the client to the server. The server sends a challenge back to the client. The challenge is encrypted and then sent back to the server. The server compares the value from the client and if the information matches, the server grants authorization. If the response fails, the session fails and the request pHase starts overExplanation
