Usernames, passwords, e-mail addresses, and the location of CGI scripts may be obtained from which of the following information sources?

1. A. Company web site
2. B. Search engines
3. C. EDGAR Database query
4. D. Whois query

Correct Answer: A
Whois query would not enable us to find the CGI scripts whereas in the actual website, some of them will have scripts written to make the website more user friendly. The EDGAR database would in fact give us a lot of the information requested but not the location of CGI scripts, as would a simple search engine on the Internet if you have the time needed.
