[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A gaming company is moving its public scoreboard from a data center to the AWS Cloud. The company uses Amazon EC2 Windows Server instances behind an Application Load Balancer to host its dynamic application. The company needs a highly available storage solution for the application. The application consists of static files and dynamic server-side code.

Which combination of steps should a solutions architect take to meet these requirements? (Choose two.)

A. Store the static files on Amazon S3. Use Amazon CloudFront to cache objects at the edge.
B. Store the static files on Amazon S3. Use Amazon ElastiCache to cache objects at the edge.
C. Store the server-side code on Amazon Elastic File System (Amazon EFS). Mount the EFS volume on each EC2 instance to share the files.
D. Store the server-side code on Amazon FSx for Windows File Server. Mount the FSx for Windows File Server volume on each EC2 instance to share the files.
E. Store the server-side code on a General Purpose SSD (gp2) Amazon Elastic Block Store (Amazon EBS) volume. Mount the EBS volume on each EC2 instance to share the files.

A because Elasticache, despite being ideal for leaderboards per Amazon, doesn't cache at edge locations. D because FSx has higher performance for low latency needs. https://www.techtarget.com/searchaws/tip/Amazon-FSx-vs-EFS-Compare-the-AWS-file-services "FSx is built for high performance and submillisecond latency using solid-state drive storage volumes. This design enables users to select storage capacity and latency independently. Thus, even a subterabyte file system can have 256 Mbps or higher throughput and support volumes up to 64 TB."

The reasons are: Storing static files in S3 with CloudFront provides durability, high availability, and low latency by caching at edge locations. FSx for Windows File Server provides a fully managed Windows native file system that can be accessed from the Windows EC2 instances to share server-side code. It is designed for high availability and scales up to 10s of GBPS throughput. EFS and EBS volumes can be attached to a single AZ. FSx and S3 are replicated across AZs for high availability.

Key: Static files and dynamic server-side code. Key: Windows Server. The answer is A because S3 is for static files, and CloudFront is a CDN. The second answer is D because FSx works for Windows File Server. It's not C because EFS is just for Linux. It's not E because EBS doesn't share files between EC2 instances.
