AWS Certified Cloud Practitioner — Question 803

A company provides a web-based ecommerce service that runs in two Availability Zones within a single AWS Region. The web service distributes content that is stored in the Amazon S3 Standard storage class. The company wants to improve the web service’s performance globally.

What should the company do to meet this requirement?

Answer options

• A. Change the S3 storage class to S3 Intelligent-Tiering.
• B. Deploy an Amazon CloudFront distribution to cache web server content in edge locations.
• C. Use Amazon API Gateway for the web service.
• D. Migrate the website ecommerce servers to Amazon EC2 with enhanced networking.

Correct answer: B

Explanation

Deploying an Amazon CloudFront distribution is the best way to improve global performance because it caches content at edge locations closer to worldwide users, reducing latency. Changing the S3 storage class to S3 Intelligent-Tiering only optimizes storage costs rather than delivery speed. Utilizing API Gateway or enabling enhanced networking on EC2 instances does not address global content distribution latency as effectively as a CDN.
