Question

A company has a batch-processing system that uses Amazon S3, Amazon EC2, and AWS Key Management Service (AWS KMS). The system uses two AWS accounts: Account A and Account B. Account A hosts an S3 bucket that stores the objects that will be processed. The S3 bucket also stores the results of the processing. All the S3 bucket objects are encrypted by a KMS key that is managed in Account A. Account B hosts a VPC that has a fleet of EC2 instances that access the S3 bucket in Account A by using statements in the bucket policy. The VPC was created with DNS hostnames enabled and DNS resolution enabled. A security engineer needs to update the design of the system without changing any of the system's code. No AWS API calls from the batch-processing EC2 instances can travel over the internet. Which combination of steps will meet these requirements? (Choose two.)

Accepted Answer

Correct answer: A, C. The correct answer is A, C. Option A: In the Account B VPC, create a gateway VPC endpoint for Amazon S3. For the gateway VPC endpoint, create a resource policy that allows the s3:GetObject, s3:ListBucket, s3:PutObject, and s3:PutObjectAcl actions for the... Option C: In the Account B VPC, create an interface VPC endpoint for AWS KMS. For the interface VPC endpoint, create a resource policy that allows the kms:Encrypt, kms:Decrypt, and kms:GenerateDataKey actions for the KMS key. E... Amazon S3 provides durable, scalable object storage that is fully managed. A gateway VPC endpoint gives private, no-cost access to Amazon S3 and DynamoDB from within the VPC. A VPC endpoint provides private connectivity to AWS services without traversing the public internet.
