QuestionQ13

Develop for Azure storage

You are developing an Azure App Service-hosted ASP.NET Core web app that delivers video-on-demand streaming media. You enable Azure Content Delivery Network (CDN) Standard for the web endpoint. Customers download videos from the web app by using a URL such as http://www.contoso.com/content.mp4?quality=1.

All media content must expire from the cache after one hour. Videos with different quality levels must be delivered from the closest regional point-of-presence (POP) node.

You need to configure Azure CDN caching rules. Which options should you use?

Select
Caching behavior
Cache expiration duration
Query string caching behavior
Explanation

Override enforces the configured CDN cache lifetime instead of honoring an origin-provided expiration value, ensuring that media expires after one hour. Caching every unique URL makes the quality query-string value part of the cache key, so each video-quality variant is cached and delivered correctly from CDN edge POPs.
