AWS Certified Solutions Architect – Associate (SAA-C02) — Question 125

A company's dynamic website is hosted using on-premises servers in the United States. The company is launching its product in Europe, and it wants to optimize site loading times for new European users. The site's backend must remain in the United States. The product is being launched in a few days, and an immediate solution is needed.
What should the solutions architect recommend?

Answer options

• A. Launch an Amazon EC2 instance in us-east-1 and migrate the site to it.
• B. Move the website to Amazon S3. Use cross-Region replication between Regions.
• C. Use Amazon CloudFront with a custom origin pointing to the on-premises servers.
• D. Use an Amazon Route 53 geo-proximity routing policy pointing to on-premises servers.

Correct answer: C

Explanation

The correct answer is C because Amazon CloudFront can cache content at edge locations close to European users, significantly improving load times while keeping the backend in the U.S. Option A involves migrating to EC2, which does not address the immediate need for optimization. Option B does not provide the required performance improvements for dynamic content, and option D does not effectively reduce latency for European users.
