AWS Certified Solutions Architect – Associate (SAA-C02) — Question 98

A company recently launched its website to serve content to its global user base. The company wants to store and accelerate the delivery of static content to its users by leveraging Amazon CloudFront with an Amazon EC2 instance attached as its origin.
How should a solutions architect optimize high availability for the application?

Answer options

• A. Use Lambda@Edge for CloudFront.
• B. Use Amazon S3 Transfer Acceleration for CloudFront.
• C. Configure another EC2 instance in a different Availability Zone as part of the origin group.
• D. Configure another EC2 instance as part of the origin server cluster in the same Availability Zone.

Correct answer: C

Explanation

The correct answer is C because adding another EC2 instance in a different Availability Zone provides redundancy and improves fault tolerance, ensuring high availability. Options A and B do not directly address high availability concerns, while D does not leverage the benefits of multiple Availability Zones, which is essential for resilience.
