EXPAND here for the FULL EXPLANATION.
Correct option:
Amazon ECS with EC2 launch type is charged based on EC2 instances and EBS volumes used. Amazon ECS with Fargate launch type is charged based on vCPU and memory resources that the containerized application requests
Lets recap ECS a bit. Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service. ECS allows you to easily run, scale, and secure Docker container applications on AWS.
What is ECS task?
Launch Docker containers on AWS = Launch ECS Tasks on ECS Clusters

With the Fargate launch type, you pay for the amount of vCPU and memory resources that your containerized application requests. vCPU and memory resources are calculated from the time your container images are pulled until the Amazon ECS Task terminates, rounded up to the nearest second. With the EC2 launch type, there is no additional charge for the EC2 launch type. You pay for AWS resources (e.g. EC2 instances or EBS volumes) you create to store and run your application.
Incorrect options:
Enable ElastiCache Redis for DynamoDB and Amazon CloudFront for Amazon Both Amazon ECS with EC2 launch type and Amazon ECS with Fargate launch type are charged based on vCPU and memory resources that the containerized application requests.
Both Amazon ECS with EC2 launch type and Amazon ECS with Fargate launch type are charged based on Amazon EC2 instances and Amazon EBS Elastic Volumes used.
As explained above. With the Fargate launch type, you pay for the amount of vCPU and memory resources.
Both Amazon ECS with EC2 launch type and Amazon ECS with Fargate launch type are just charged based on Elastic Container Service used per hour
It is a distractor.
