[All AWS Certified Solutions Architect - Professional Questions]

A retail company has a custom .NET web application running on AWS that uses Microsoft SQL Server for the database. The application servers maintain a user's session locally.
Which combination of architecture changes are needed to ensure all tiers of the solution are highly available? (Choose three.)

A. Refactor the application to store the user's session in Amazon ElastiCache. Use Application Load Balancers to distribute the load between application instances.
B. Set up the database to generate hourly snapshots using Amazon EBS. Configure an Amazon CloudWatch Events rule to launch a new database instance if the primary one fails.
C. Migrate the database to Amazon RDS for SQL Server. Configure the RDS instance to use a Multi-AZ deployment.
D. Move the .NET content to an Amazon S3 bucket. Configure the bucket for static website hosting.
E. Put the application instances in an Auto Scaling group. Configure the Auto Scaling group to create new instances if an instance becomes unhealthy.
F. Deploy Amazon CloudFront in front of the application tier. Configure CloudFront to serve content from healthy application instances only.

C,D,E. The question asks for a highly available solution for all tiers. A - gives load balancing, not high availability.

Answer is A,C,E D is incorrect because S3 doesn't support server-side scripting like "ASP.NET, PHP, or JSP". In addition, high availability is one of the features of ELB. ELB Features - https://aws.amazon.com/elasticloadbalancing/features/#:~:text=High%20availability,response%20to%20incoming%20application%20traffic. S3 static web site hosting - https://docs.amazonaws.cn/en_us/AmazonS3/latest/user-guide/static-website-hosting.html "You can host a static website on Amazon S3. On a static website, individual webpages include static content. A static website might also contain client-side scripts. By contrast, a dynamic website relies on server-side processing, including server-side scripts such as PHP, JSP, or ASP.NET. Amazon S3 does not support server-side scripting."
