Question 1 · Design Cost-Optimized Architectures Open

A company runs a website on Amazon EC2 instances behind an Application Load Balancer (ALB). The website delivers static content. Traffic to the website is increasing. The company wants to reduce the website hosting costs as much as possible. Which solution will meet these requirements?

Answer: A For a website that serves only static content, Amazon S3 is the appropriate origin because it can host static assets without running web servers, and Amazon CloudFront can cache and distribute that content globally at scale. This removes the ongoing cost of EC2 instances and the ALB while still supporting increasing traffic efficiently. ElastiCache is not the standard hosting layer for S3 static websites, and adding ALB or EC2 in front of AWS Amplify would add unnecessary infrastructure instead of minimizing cost. **Learn more:** [Use Amazon S3 website hosting to host without a single web server](https://docs.aws.amazon.com/whitepapers/latest/build-static-websites-aws/use-amazon-s3-website-hosting-to-host-without-a-single-web-server.html) · [Get started with a secure static website](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/getting-started-secure-static-website-cloudformation-template.html)

Question 2 · Design Cost-Optimized Architectures Open

A recent review of a company's IT spending shows a need to lower backup costs. The company's chief information officer wants to simplify the on-premises backup infrastructure and reduce expenses by removing the use of physical backup tapes. The company must retain its existing investment in on-premises backup applications and workflows. What should a solutions architect recommend?

Answer: D AWS Storage Gateway Tape Gateway is built for replacing physical tape infrastructure while preserving existing backup applications and operational processes. It exposes a virtual tape library over an iSCSI interface, which lets current tape-based backup software continue to operate with minimal change while eliminating physical tapes and their associated management costs. Amazon EFS is a network file system, not a tape replacement service, and it does not provide the VTL capability required to maintain existing tape-oriented backup workflows. **Learn more:** [How Tape Gateway works](https://docs.aws.amazon.com/storagegateway/latest/tgw/StorageGatewayConcepts.html)

Question 3 · Design Resilient Architectures Open

A gaming company is migrating 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 run its dynamic application. The company requires a highly available storage solution for the application. The application includes static files and dynamic server-side code. Which combination of steps should a solutions architect take to satisfy these requirements? **(Choose two.)**

Answer: A, D Amazon S3 provides highly available storage for static content, and Amazon CloudFront is the AWS service that caches that content at edge locations for low-latency delivery. For Windows-based Amazon EC2 instances that must share server-side code, Amazon FSx for Windows File Server is the appropriate highly available shared file storage service because it exposes SMB file shares that Windows instances can mount. Amazon EFS is not supported for Microsoft Windows–based EC2 instances, and Amazon EBS is not the right choice for shared highly available storage across multiple EC2 application servers. **Learn more:** [Request and response behavior for Amazon S3 origins - Amazon CloudFront](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/RequestAndResponseBehaviorS3Origin.html) · [Amazon CloudFront Documentation](https://docs.aws.amazon.com/cloudfront/)
