Not sure if C is correct in this particular scenario. From https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-dg.pdf Page 202 of the SageMaker Guide has: If you allowed access to resources from your VPC, enable direct internet access. For Direct internet access, choose Enable. Without internet access, you can't train or host models from notebooks on this notebook instance unless your VPC has a NAT gateway and your security group allows outbound connect

There are two possible solutions, but the safer solution and easier is trough VPC endpoints. You can connect to your notebook instance from your VPC through an interface endpoint in your Virtual Private Cloud (VPC) instead of connecting over the internet. When you use a VPC interface endpoint, communication between your VPC and the notebook instance is conducted entirely and securely within the AWS network. And there is not problem that the notebooks does not have public internet. Because Amazon SageMaker notebook instances support Amazon Virtual Private Cloud (Amazon VPC) interface endpoints that are powered by AWS PrivateLink. Each VPC endpoint is represented by one or more Elastic Network Interfaces (ENIs) with private IP addresses in your VPC subnets. Each VPC endpoint is represented by one or more Elastic Network Interfaces (ENIs) with private IP addresses in your VPC subnets... so the Answer is C.

C is correct. "The VPC interface endpoint connects your VPC directly to the Amazon SageMaker API or Runtime without an internet gateway, **NAT** device, VPN connection, or AWS Direct Connect connection." https://docs.aws.amazon.com/sagemaker/latest/dg/interface-vpc-endpoint.html

Selected Answer: C

Explanation: The company's data security policy does not allow internet access, so the solution must allow Amazon SageMaker to function privately within the VPC without internet access. VPC Interface Endpoints (AWS PrivateLink) for SageMaker allow services to communicate privately over the AWS network, without requiring an Internet Gateway (IGW) or NAT Gateway.

The answer is C. - If you want to allow internet access, you must use a NAT gateway with access to the internet, for example through an internet gateway. - If you don't want to allow internet access, create interface VPC endpoints (AWS PrivateLink) to allow Studio Classic to access the following services with the corresponding service names. You must also associate the security groups for your VPC with these endpoints. This is exactly what's written in the ref. doc given in the answer section of the question.

C. To enable Amazon SageMaker service without enabling direct internet access to Amazon SageMaker notebook instances, while adhering to a corporate data security policy that restricts internet communication, the company can: C. Create Amazon SageMaker VPC interface endpoints within the corporate VPC. This option involves setting up VPC (Virtual Private Cloud) interface endpoints for Amazon SageMaker within the corporate VPC (Virtual Private Cloud). This is done using AWS PrivateLink, which allows private connectivity between AWS services using private IP addresses. By creating VPC interface endpoints, the traffic between the corporate VPC and Amazon SageMaker does not traverse the public internet, thereby meeting the corporate data security requirements.

A would allow instances in a private subnet to initiate outbound internet traffic. This is against the requirement of no direct internet access.

Selected Answer: C

To prevent SageMaker from providing internet access to your Studio notebooks, you can disable internet access by specifying the VPC only network access type when you the onboard to Studio or call CreateDomain API. As a result, you won't be able to run a Studio notebook unless your VPC has an interface endpoint to the SageMaker API and runtime, or a NAT gateway with internet access, and your security groups allow outbound connections.

To disable direct internet access, under Direct Internet access, simply choose Disable – use VPC only , and select the Create notebook instance button at the bottom. You are ready to go. from: https://aws.amazon.com/blogs/machine-learning/customize-your-amazon-sagemaker-notebook-instances-with-lifecycle-configurations-and-the-option-to-disable-internet-access/#:~:text=To%20disable%20direct%20internet%20access%2C%20under%20Direct%20Internet%20access%2C%20simply,running%2C%20without%20direct%20internet%20access.

A VPC interface endpoint is a private connection between a VPC and Amazon SageMaker that is powered by AWS PrivateLink. With a VPC interface endpoint, traffic between the VPC and Amazon SageMaker never leaves the Amazon network.

If the question just had the last sentence, the answer would be A or C, per this page:https://docs.aws.amazon.com/sagemaker/latest/dg/appendix-notebook-and-internet-access.html. "To disable direct internet access, you can specify a VPC for your notebook instance. By doing so, you prevent SageMaker from providing internet access to your notebook instance. As a result, the notebook instance won't be able to train or host models unless your VPC has an interface endpoint (PrivateLink) or a NAT gateway, and your security groups allow outbound connections." HOWEVER, the question has more context that internet access is not allowed by the corporate policy. ("When you use a VPC interface endpoint, communication between your VPC and the notebook instance is conducted entirely and securely within the AWS network.") Therefore, the answer must be ONLY C.

I see a lot of people employing pretzel logic to try to explain why they should be using NAT. The question states no internet communication. Period. No internet means no NAT. Answer is C.
