AWS Certified Cloud Practitioner (CLF-C02) — Question 460

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 multiple AWS Regions.
• B. Use EC2 instances in multiple edge locations.
• C. Use EC2 instances in the same Availability Zone but in different AWS Regions.
• D. Use Amazon CloudFront with the EC2 instances configured as the source.

Correct answer: A

Explanation

Deploying Amazon EC2 instances across multiple AWS Regions ensures high availability and disaster recovery because AWS Regions are geographically isolated from each other. Edge locations cannot host EC2 instances, and an Availability Zone is physically located within a single region, making option C impossible. Amazon CloudFront serves as a content delivery network but does not provide regional redundancy for the underlying EC2 compute resources.
