Correct Answer: A These formats are supported in the lists of paths to purge: - Single path purge: Purge individual assets by specifying the full path of the asset (without the protocol and domain), with the file extension, for example, /pictures/strasbourg.png; - Wildcard purge: Asterisk (*) may be used as a wildcard. Purge all folders, subfolders, and files under an endpoint with /* in the path or purge all subfolders and files under a specific folder by specifying the folder followed by /*, for example, /pictures/*. - Root domain purge: Purge the root of the endpoint with "/" in the path. Here since we just need to purge individual assets, we can just make use of the Single path purge as the format for purging assets.

Selected Answer: A

The correct answer is A. Single path. In Azure Front Door, you can purge cached content by specifying individual paths (URLs) to the content. This is known as a single path purge. This would be the most appropriate option if you need to purge specific files based on Response Header values. Option B, wildcard, allows you to purge multiple paths that match a certain pattern, and option C, root domain, purges all cached content for a specific domain. These options would not be as precise as a single path purge for purging specific files.
