AWS Certified Solutions Architect – Associate (SAA-C02) — Question 136

A company is running a two-tier ecommerce website using AWS services. The current architect uses a publish-facing Elastic Load Balancer that sends traffic to
Amazon EC2 instances in a private subnet. The static content is hosted on EC2 instances, and the dynamic content is retrieved from a MySQL database. The application is running in the United States. The company recently started selling to users in Europe and Australia. A solutions architect needs to design solution so their international users have an improved browsing experience.
Which solution is MOST cost-effective?

Answer options

• A. Host the entire website on Amazon S3.
• B. Use Amazon CloudFront and Amazon S3 to host static images.
• C. Increase the number of public load balancers and EC2 instances.
• D. Deploy the two-tier website in AWS Regions in Europe and Australia.

Correct answer: B

Explanation

The correct answer is B because using Amazon CloudFront with Amazon S3 for static content delivery reduces latency and improves load times for international users, while also being cost-effective. Option A is not ideal as it does not address dynamic content. Option C increases costs without improving user experience significantly, and option D, while effective, is more expensive than necessary for optimizing static content delivery.
