The technical-support department has a requirement to access an intranet server. When configuring a User Authentication rule to achieve this, which of the following should you remember?

A.
The Security Gateway first checks if there is any rule that does not require authentication for this type of connection before invoking the Authentication Security Server.

B.
Once a user is first authenticated, the user will not be prompted for authentication again until logging out.

C.
You can only use the rule for Telnet, FTP, SMTP, and rlogin services.

D.
You can limit the authentication attempts in the Authentication tab of the User Properties screen.
