Which solution should you recommend to provide highly available streaming for a video application while storing data geographically close to the users?

Azure Content Delivery Network (CDN)
Azure Redis Cache
Azure App Service Web Apps
Azure App Service Isolated

The correct answer is: Azure Content Delivery Network (CDN)

Recommending Azure Content Delivery Network (CDN) is the most suitable choice for providing highly available streaming for a video application while ensuring that data is stored geographically close to users. The primary purpose of a CDN is to deliver content more efficiently by caching it in multiple locations around the world. This means that when a user requests a video stream, the content can be delivered from a nearby edge location, thereby reducing latency and improving load times. Furthermore, Azure CDN optimizes content delivery, providing benefits like bandwidth savings and offloading the origin server. This setup not only improves the user experience but also enhances the application’s performance and availability as it can handle high traffic spikes more effectively by serving repeated requests from the cache rather than the origin server. This choice stands out particularly for video applications where streaming quality and speed are critical, and geographical proximity to users plays a significant role in performance. The other options, such as Azure Redis Cache, Azure App Service Web Apps, and Azure App Service Isolated, do not specifically address the needs for content delivery and caching at scale in various geographical locations as effectively as Azure CDN does.
