The Common Gateway Interface (CGI) specification is used for creating executable programs that run on a Web server. CGI defines the communication link between a Web server and Web applications. It gives a network or Internet resource access to specific programs.

It then returns these results to the user by means of an HTML page. Answer: A is incorrect. CGI programs do not execute on routers.

The Routing and Remote Access service can log all the records of authentication and accounting information for connection attempts when Windows authentication or accounting is enabled. This can be done by enabling the log authentication requests in the properties of the RemoteAccess Logging folder, in the Routing and Remote Access snap-in, where you can configure the type of activity to log, i.e., accounting or authentication activity and log file settings. This information is stored in the form of a log file in '%SystemRoot%System32LogFiles' folder. For each authentication attempt, the name of the remote access policy, that either accepted or rejected the connection attempt, is recorded. The logged information is useful to track remote access usage, and authentication attempts.
