Microsoft Azure Architect Design (AZ-304) Practice Test

Which statement is true about using Azure Content Delivery Network (CDN) for media delivery?

1. CDN does not improve performance for video streaming

2. CDN can cache static content to improve user experience

3. CDN is suitable only for dynamic content

4. CDN increases latency for end users

The correct answer is: CDN can cache static content to improve user experience

Using Azure Content Delivery Network (CDN) significantly enhances the performance of media delivery by caching static content at various edge locations around the world. This caching reduces the physical distance between users and the content they are accessing. As a result, when a user requests media such as images, videos, or scripts that are stored in the CDN, they can retrieve it from a nearby edge server rather than having to connect to the origin server, which may be located much farther away. The benefits of this approach include faster load times, reduced latency, and an overall improved user experience. By utilizing the CDN's caching capabilities, businesses can serve content to their users more efficiently, which is crucial for applications like video streaming and web applications that rely heavily on static assets. In contrast, the other statements do not accurately reflect the capabilities of Azure CDN. For instance, saying that CDN does not improve performance for video streaming overlooks the essential role that CDNs play in optimizing media delivery. Furthermore, suggesting that CDN is suitable only for dynamic content mischaracterizes its primary function, which primarily targets the efficient delivery of static content, although it can support dynamic content as well. Lastly, the idea that CDN increases latency contradicts its fundamental purpose, which is to reduce latency by bringing
