Watchguard Network Security Practice Test

Which HTTP proxy action rule must be modified to allow download of a blocked installation file?

1. HTTP Request > Request Methods

2. HTTP Response > Body Content Types

3. HTTP Response > Header Fields

4. WebBlocker

The correct answer is: HTTP Request > Request Methods

To allow the download of a blocked installation file, modifying the HTTP Request > Request Methods rule is the correct approach. This rule governs which methods are permitted by the proxy when a client initiates a request to a server. Installation files are typically downloadable through requests made with methods such as GET. If the specific request method for downloading files is restricted or blocked, the installation file will be prevented from being downloaded, regardless of the actual content type being served. Adjusting the settings related to request methods enables you to permit specific types of requests that are necessary for downloading installation files. This tactic directly addresses the need to change the rules governing how requests are handled before reaching the server. In contrast, focusing on the other options would not directly resolve the issue. For example, modifying HTTP Response > Body Content Types would not affect the request made to download the file; rather, it deals with the server's responses based on the types of content it sends back. Similarly, changing HTTP Response > Header Fields involves the metadata in responses and wouldn’t be practical in allowing specific methods of request that prevent access to certain files. Lastly, while WebBlocker can filter potentially harmful contents based on categories, it may not provide the granularity needed to allow specific file types without
