Common gateway interface applications.
B.
Server-side scripting.
C.
I/O and Network subsystems.
D.
Active Server Pages.
C is correct
C is correct because the Input/Output (I/O) and Network subsystems are two of the most critical hardware elements affecting how fast data can be processed . A is incorrect because common gateway interface applications or CGI scripting, can extend the features of a Web server, but not improve the performance. B is incorrect because server-side scripting creates programs that run on the Server to accomplish a variety of tasks, but not increase the speed with which they are completed. D is incorrect because Active Server Pages (ASP) is a proprietary or middleware solution for CGI scripting.
2.

Please select the best answer.
A.
ASP and PHP
B.
ServerSide JavaScript (SSJS) and ASP
C.
PHP and PERL
D.
Cold Fusion Server and perl
C is the correct answer.
PHP3 and perl are designed to work on platforms, including AIX, Linux, Windows NT, HP-UX, Solaris, and even Macintosh systems running WebStar. A is incorrect because even though ASP is free of charge after you purchase Windows NT, it does not work on any other operating system. B is incorrect for the same reason, and because SSJS works only with Netscape Enterprise Servers. D is incorrect because Cold Fusion Server is sold by Allaire Corporation.
3.
Which of the following hardware elements is crucial to effective Web server performance?
Please select the best answer.
A.
The I/O subsystem
B.
The amount of system memory
C.
CPU speed
D.
The network subsystem
A is the correct answer.
An e-commerce Web server uses many different applications and services to do its job. Each hit requires hard drive access, as well as numerous calls to CGI daemons and scripts. Therefore, the I/O subsystem is the most important. System memory and the network subsystem are next on the list. CPU speed, although important, comes last.
