Microsoft Azure Administrator (AZ104) Practice Exam

Which service can improve content delivery speed across different regions globally?

1. Azure Traffic Manager

2. Azure CDN

3. Azure Front Door

4. Network Security Group

The correct answer is: Azure CDN

The Azure Content Delivery Network (CDN) is specifically designed to enhance content delivery speeds by caching content close to users in various geographical locations. By utilizing a global network of servers, Azure CDN reduces latency and improves response times for end users, ensuring that content is delivered from the nearest edge node. This is particularly beneficial for high-bandwidth content such as videos, images, and large files, as well as dynamic content that requires quick loading times for users distributed across different regions. Azure CDN works seamlessly with other Azure services to provide an efficient way to serve large volumes of content while also optimizing the performance of applications globally. By leveraging strategically located points of presence (PoPs), Azure CDN ensures that requests for content are handled as swiftly as possible, significantly improving the overall user experience. In contrast, Azure Traffic Manager is primarily focused on traffic routing and ensuring high availability by directing user traffic across various endpoints based on different routing methods. Azure Front Door combines application acceleration and security features, optimizing web application performance and allowing for global load balancing, but its primary function is not solely content delivery like Azure CDN. A Network Security Group is related to controlling inbound and outbound traffic to network resources and doesn't play a role in content delivery speed.
