What is the most effective use of Amazon Elastic Container Service (ECS) when refactoring a monolithic application to use a microservice architecture? A. Create services that each provide a distinct function of the application, and run each service in a separate container that Amazon ECS manages. B. Create services that each provide a distinct function of the application, and run each service in a single container that Amazon ECS manages. C. Port the application to a new image and run it in a container that Amazon ECS manages. D. Refactor the application and centralize common functions to create a smaller code footprint

What is a serverless solution for creating a simple web form? A. Host static assets in an Amazon S3 bucket, use an Amazon DynamoDB table, and use Amazon API Gateway and AWS Lambda functions to interact with the database. B. Host website assets in a container in an Amazon ECS cluster, use an Amazon DynamoDB table, and use server-side scripts to interact with the databse. C. Host static assets in an Amazon S3 bucket, use an Amazon RDS database, and use Amazon API Gateway and AWS Lambda functions to interact with the database. D. Host website assets in a container in a Amazon ECS cluster, use an Amazon RDS database, and use server-side scripts to interact with the database.

An environmental science organisation wants to provide HTTPS read-only access to its sensors and databases to any users around the world. The goal is enabling users to create their own custom real-time data visualizations to help improve climate science. Which solution is efficient and secure? A. Create web proxy servers on Amazon EC2 instances in an Auto Scaling group, which is served by an Elastic Load Balancing load balancer. B. Create user accounts in the organizations' system to allow access C. Create a public interface to the sensors and databases by using Amazon API Gateway. D. Create a microservices architecture by using Amazon ECS
