Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

What is a distributed network of servers that efficiently delivers web content to users?

1. Load Balancer

2. Application Gateway

3. Content Delivery Network

4. Traffic Manager

The correct answer is: Content Delivery Network

The correct answer is indeed a Content Delivery Network (CDN). A CDN is a system composed of a network of servers strategically distributed in various geographic locations. This architecture allows for the efficient delivery of web content, such as images, videos, and other resources, to users based on their proximity to the nearest server in the network. By caching content at multiple locations, a CDN reduces latency and improves load times for users, providing a better overall experience. It is particularly beneficial for websites and applications with a global audience, as it minimizes the distance data must travel, leading to faster access and reduced bandwidth usage. Load balancers and application gateways serve different purposes, with load balancers managing traffic distribution across multiple servers, and application gateways providing routing and security features for web applications. Traffic Manager is more focused on routing traffic across global Azure regions based on performance and availability but does not provide the same caching capabilities for content delivery as a CDN.
