AWS Certified Solutions Architect - Associate

  • Topic 1 Question 944

    An ecommerce company is preparing to deploy a web application on AWS to ensure continuous service for customers. The architecture includes a web application that the company hosts on Amazon EC2 instances, a relational database in Amazon RDS, and static assets that the company stores in Amazon S3.

    The company wants to design a robust and resilient architecture for the application.

    Which solution will meet these requirements?

    • Deploy Amazon EC2 instances in a single Availability Zone. Deploy an RDS DB instance in the same Availability Zone. Use Amazon S3 with versioning enabled to store static assets.

    • Deploy Amazon EC2 instances in an Auto Scaling group across multiple Availability Zones. Deploy a Multi-AZ RDS DB instance. Use Amazon CloudFront to distribute static assets.

    • Deploy Amazon EC2 instances in a single Availability Zone. Deploy an RDS DB instance in a second Availability Zone for cross-AZ redundancy. Serve static assets directly from the EC2 instances.

    • Use AWS Lambda functions to serve the web application. Use Amazon Aurora Serverless v2 for the database. Store static assets in Amazon Elastic File System (Amazon EFS) One Zone-Infrequent Access (One Zone-IA).
