To answer this question, we need to understand the components of IIS (Internet Information Services). Let's go through each option:
Option A) FTP - This option is incorrect because FTP (File Transfer Protocol) is a component of IIS. It allows for the transfer of files between a client and a server.
Option B) Common files - This option is incorrect because Common files are a component of IIS. They include shared files and resources that are used by multiple websites hosted on the server.
Option C) Background Intelligent Transfer Service (BITS) - This option is incorrect because BITS is a component of IIS. It is a service that enables the transfer of files in the background, allowing for efficient use of network bandwidth.
Option D) All of the choices are components of IIS - This option is incorrect. The correct answer is that not all of the choices are components of IIS. In this case, the correct answer is that D is not a component of IIS.
The correct answer is: D.
