You plan to deploy a website to Azure. The website will be accessed by users worldwide and will host large video files.
You need to recommend which Azure feature must be used to provide the best video playback experience.

A. B. C. D.C
The question states that users are located worldwide and will be downloading large video files. The video playback experience would be improved if they can download the video from servers in the same region as the users. We can achieve this by using a content deliver network.
A content delivery network (CDN) is a distributed network of servers that can efficiently deliver web content to users. CDNs store cached content on edge servers in point-of-presence (POP) locations that are close to end users, to minimize latency.
Azure Content Delivery Network (CDN) offers developers a global solution for rapidly delivering high-bandwidth content to users by caching their content at strategically placed physical nodes across the world. Azure CDN can also accelerate dynamic content, which cannot be cached, by leveraging various network optimizations using CDN POPs. For example, route optimization to bypass Border Gateway Protocol (BGP).
The benefits of using Azure CDN to deliver web site assets include:
-> Better performance and improved user experience for end users, especially when using applications in which multiple round-trips are required to load content.
-> Large scaling to better handle instantaneous high loads, such as the start of a product launch event.
-> Distribution of user requests and serving of content directly from edge servers so that less traffic is sent to the origin server.
https://docs.microsoft.com/en-us/azure/cdn/cdn-overviewThe recommended Azure feature for hosting large video files and providing the best video playback experience for users worldwide is a content delivery network (CDN). Therefore, the correct answer is option C.
Explanation:
A content delivery network (CDN) is a distributed network of servers that delivers content to users based on their geographic location. By caching content closer to users, CDNs reduce the distance between users and the content they want to access, which improves the overall performance and speed of delivery.
CDNs are designed to handle large media files, including video, audio, and images, and provide faster and more reliable access to these files for users worldwide. When a user requests a video file, the CDN will redirect the user to the closest server with a cached copy of the file, reducing the latency and providing a better video playback experience.
In contrast, an application gateway (Option A) is a load balancer that provides web application firewall (WAF) protection and SSL/TLS termination. An Azure ExpressRoute circuit (Option B) is a dedicated private connection between an on-premises infrastructure and Azure datacenters. While these features have their use cases, they are not designed to handle large media files or provide a better video playback experience.
An Azure Traffic Manager profile (Option D) is a DNS-based traffic load balancer that distributes traffic across multiple endpoints. Although it can help improve application performance by directing users to the closest endpoint, it does not cache or optimize media files, and therefore, it is not the best Azure feature for hosting large video files.
