Answer: Amazon Elastic File System (Amazon EFS), Amazon EC2

The correct answer is B (Amazon Elastic File System, Amazon EFS) and E (Amazon EC2). Amazon EFS is a file storage service that provides a persistent file system for your EC2 instances and requires a VPC to isolate your EFS filesystem from other resources in the AWS Cloud. Amazon EC2 is a service that provides virtual machines that you can use to run your applications and also requires a VPC to isolate your EC2 instances from other resources in the AWS Cloud. Options A (Amazon S3), C (Amazon Cognito), and D (Amazon DynamoDB) do not require the use of a VPC.
