To answer this question, we need to understand the concept of Concurrent CGI applications and the default settings of IIS 6.
Concurrent CGI applications refer to the number of CGI (Common Gateway Interface) applications that can be executed simultaneously by the web server.
In IIS 6, the default setting allows for a maximum of 4 concurrent CGI applications to be executed at the same time.
Let's go through each option to understand why it is correct or incorrect:
Option A) 2 - This option is incorrect because the default setting in IIS 6 allows for 4 concurrent CGI applications, not 2.
Option B) 4 - This option is correct because the default setting in IIS 6 allows for a maximum of 4 concurrent CGI applications to be executed at the same time.
Option C) 6 - This option is incorrect because the default setting in IIS 6 allows for 4 concurrent CGI applications, not 6.
Option D) 7 - This option is incorrect because the default setting in IIS 6 allows for 4 concurrent CGI applications, not 7.
Option E) 8 - This option is incorrect because the default setting in IIS 6 allows for 4 concurrent CGI applications, not 8.
The correct answer is Option B) 4. This option is correct because the default setting in IIS 6 allows for a maximum of 4 concurrent CGI applications to be executed at the same time.
