A Company Recently Launched a New Service That Involves Medical

question 588

Multiple Choice

A company recently launched a new service that involves medical images. The company scans the images and sends them from its on-premises data center through an AWS Direct Connect connection to Amazon EC2 instances. After processing is complete, the images are stored in an Amazon S3 bucket. A company requirement states that the EC2 instances cannot be accessible through the internet. The EC2 instances run in a private subnet, which has a default route back to the on-premises data center for outbound internet access. Usage of the new service is increasing rapidly. A solutions architect must recommend a solution that meets the company's requirements and reduces the Direct Connect charges. Which solution accomplishes these goals MOST cost-effectively?

• A) Configure a VPC endpoint for Amazon S3. Add an entry to the private subnet's route table for the S3 endpoint.
• B) Configure a NAT gateway in a public subnet. Configure the private subnet's route table to use the NAT gateway.
• C) Configure Amazon S3 as a file system mount point on the EC2 instances. Access Amazon S3 through the mount.
• D) Move the EC2 instances into a public subnet. Configure the public subnet route table to point to an internet gateway.
