AWS Certified Solutions Architect – Associate (SAA-C02) — Question 231

A company hosts a training site on a fleet of Amazon EC2 instances. The company anticipates that its new course, which consists of dozens of training videos on the site, will be extremely popular when it is released in 1 week.
What should a solutions architect do to minimize the anticipated server load?

Answer options

• A. Store the videos in Amazon ElastiCache for Redis. Update the web servers to serve the videos using the ElastiCache API.
• B. Store the videos in Amazon Elastic File System (Amazon EFS). Create a user data script for the web servers to mount the EFS volume.
• C. Store the videos in an Amazon S3 bucket. Create an Amazon CloudFront distribution with an origin access identity (OAI) of that S3 bucket. Restrict Amazon S3 access to the OAI.
• D. Store the videos in an Amazon S3 bucket. Create an AWS Storage Gateway file gateway to access the S3 bucket. Create a user data script for the web servers to mount the file gateway.

Correct answer: C

Explanation

The correct answer is C because storing videos in Amazon S3 and using CloudFront allows for efficient content delivery, reducing server load by caching content at edge locations. Options A and B are incorrect as they do not provide effective scalability for video delivery, while option D introduces unnecessary complexity by using a file gateway instead of utilizing the direct benefits of S3 and CloudFront.
