AWS Certified Cloud Practitioner — Question 441

A company wants its Amazon EC2 instances to operate in a highly available environment, even if there is a natural disaster in a particular geographic area.

Which solution achieves this goal?

Answer options

• A. Use EC2 instances in a single Availability Zone
• B. Use EC2 instances in multiple AWS Regions
• C. Use EC2 instances in multiple edge locations.
• D. Use Amazon CloudFront with the EC2 instances configured as the source.

Correct answer: B

Explanation

Deploying Amazon EC2 instances across multiple AWS Regions provides geographic redundancy, protecting the application from full-scale regional disasters. A single Availability Zone is vulnerable to localized outages, while edge locations and Amazon CloudFront are content delivery solutions that do not host EC2 instances for high availability compute failover.
