SAP-C02 Question #108: Real Exam Question with Answer & Explanation

Question

A company runs a popular web application in an on-premises data center. The application receives four million views weekly. The company expects traffic to increase by 200% because of an advertisement that will be published soon. The company needs to decrease the load on the origin before the increase of traffic occurs. The company does not have enough time to move the entire application to the AWS Cloud. Which solution will meet these requirements?

Options

• ACreate an Amazon CloudFront content delivery network (CDN).
• BCreate an Amazon CloudFront content delivery network (CDN) that uses a Real Time Messaging
• CCreate an accelerator in AWS Global Accelerator.
• DCreate an accelerator in AWS Global Accelerator.

Explanation

To handle a massive traffic increase for an on-premises web application and decrease load on the origin without migrating, AWS Global Accelerator can optimize network routing and offload connection processing by using the AWS global network, directing user traffic efficiently to the on-premises endpoint.

Common mistakes.

• A. While Amazon CloudFront can decrease load by caching static and dynamic content, Global Accelerator specifically focuses on optimizing the network path and offloading connection processing at Layer 4 using the AWS global network, which is often more comprehensive for a sudden, large increase in general application traffic and network load to an on-premises origin.
• B. CloudFront with RTMP streaming is a specialized solution for media streaming, which is not applicable to a general web application that needs to handle increased HTTP/S traffic.
• D. This option is a duplicate of C and provides the same correct solution for the problem statement.

Concept tested. AWS Global Accelerator, traffic management, on-premises integration
