AWS Certified Solutions Architect – Associate (SAA-C03) — Question 961
A company's image-hosting website gives users around the world the ability to up load, view, and download images from their mobile devices. The company currently hosts the static website in an Amazon S3 bucket.
Because of the website's growing popularity, the website's performance has decreased. Users have reported latency issues when they upload and download images.
The company must improve the performance of the website.
Which solution will meet these requirements with the LEAST implementation effort?
Answer options
- A. Configure an Amazon CloudFront distribution for the S3 bucket to improve the download performance. Enable S3 Transfer Acceleration to improve the upload performance.
- B. Configure Amazon EC2 instances of the right sizes in multiple AWS Regions. Migrate the application to the EC2 instances. Use an Application Load Balancer to distribute the website traffic equally among the EC2 instances. Configure AWS Global Accelerator to address global demand with low latency.
- C. Configure an Amazon CloudFront distribution that uses the S3 bucket as an origin to improve the download performance. Configure the application to use CloudFront to upload images to improve the upload performance. Create S3 buckets in multiple AWS Regions. Configure replication rules for the buckets to replicate users' data based on the users' location. Redirect downloads to the S3 bucket that is closest to each user's location.
- D. Configure AWS Global Accelerator for the S3 bucket to improve network performance. Create an endpoint for the application to use Global Accelerator instead of the S3 bucket.
Correct answer: A
Explanation
Amazon CloudFront is the most efficient way to cache and serve static website content globally, significantly reducing download latency. To address upload latency with minimal effort, enabling S3 Transfer Acceleration utilizes AWS edge locations to route upload traffic over the AWS backbone network. Other options, such as migrating to Amazon EC2 or setting up multi-region S3 replication, introduce unnecessary architectural complexity and higher operational overhead.
