AWS Certified Cloud Practitioner — Question 813

A company wants its Amazon EC2 instances to share the same geographic area but use redundant underlying power sources.

Which solution will meet these requirements?

Answer options

• A. Use EC2 instances across multiple Availability Zones in the same AWS Region.
• B. Use Amazon CloudFront as the database for the EC2 instances.
• C. Use EC2 instances in the same edge location and the same Availability Zone.
• D. Use EC2 instances in AWS OpsWorks stacks in different AWS Regions.

Correct answer: A

Explanation

Deploying Amazon EC2 instances across different Availability Zones within the same AWS Region ensures they reside in the same geographic area while utilizing distinct, redundant power supplies and infrastructure. Amazon CloudFront is a content delivery network, not a database, and edge locations do not host standard EC2 instances. Spreading instances across different AWS Regions would violate the requirement to keep them in the same geographic area.
