AWS Certified Cloud Practitioner — Question 790

A company wants its Amazon EC2 instances to provide a low-latency static website to global users.

What should the company do to meet this requirement?

Answer options

• A. Use the EC2 instances in multiple edge locations.
• B. Use an Application Load Balancer with the EC2 instances configured as the target.
• C. Use the EC2 instances in the same Availability Zone but in different AWS Regions.
• D. Use Amazon Cloud Front with the EC2 instances configured as the source.

Correct answer: D

Explanation

Amazon CloudFront is a content delivery network (CDN) that caches static content at edge locations worldwide, drastically reducing latency for global users by serving the website from the closest geographic location. An Application Load Balancer distributes incoming traffic but does not cache content globally to minimize latency. Additionally, EC2 instances cannot be run inside edge locations, and Availability Zones are isolated locations within a single AWS Region, not across multiple regions.
