AWS Certified Cloud Practitioner (CLF-C02) — Question 146

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 approach will achieve this goal?

Answer options

• A. Use EC2 instances in multiple AWS Regions.
• B. Use EC2 instances in multiple Amazon CloudFront locations.
• C. Use EC2 instances in multiple edge locations.
• D. Use EC2 instances in AWS Local Zones.

Correct answer: A

Explanation

The correct answer is A because using EC2 instances in multiple AWS Regions ensures that if one region is affected by a disaster, other regions can continue to function, thus providing high availability. The other options, such as using CloudFront locations or edge locations, do not provide the same level of regional redundancy and failover capabilities needed to maintain operational continuity during a disaster.
