AWS Certified Cloud Practitioner (CLF-C02) — Question 487

A company wants its Amazon EC2 instances to be in different locations but share the same geographic area. The company also wants to use multiple power grids and independent networking connectivity for the EC2 instances.

Which solution meets these requirements?

Answer options

• A. Use EC2 instances in multiple edge locations in the same AWS Region.
• B. Use EC2 instances in multiple Availability Zones in the same AWS Region.
• C. Use EC2 instances in multiple Amazon Connect locations in the same AWS Region.
• D. Use EC2 instances in multiple AWS Artifact locations in the same AWS Region.

Correct answer: B

Explanation

AWS Availability Zones (AZs) are designed as isolated locations within a single AWS Region, featuring their own independent power grids, cooling, and network infrastructure to ensure high availability and fault tolerance. Edge locations are utilized for content delivery via Amazon CloudFront and cannot host EC2 instances. Amazon Connect and AWS Artifact are software services rather than infrastructure deployment locations for EC2.
