In web development, which term describes a pointer in a web server configuration to a physical directory containing site files?

• A. Trigger
• B. Virtual Directory
• C. Xml
• D. Update

Answer: (B)

A virtual directory is a mapping in the web server configuration that links a URL path to a physical folder on the server. This lets the server serve files from that folder under the site’s URL space without placing them in the site's main root. In practice, you define an alias (the URL segment) and the physical path to the folder, so requests to that URL are served from the mapped directory. This concept exists in various servers (IIS uses virtual directories; Apache calls it an Alias), reinforcing that the URL route is connected to a concrete location on disk. The other terms don’t describe this mapping: a trigger is an event that starts work, XML is a data format, and update is an action that modifies something.
