Question 34

A Machine Learning Specialist uploads a dataset to an Amazon S3 bucket protected with server-side

encryption using AWS KMS.

How should the ML Specialist define the Amazon SageMaker notebook instance so it can read the same

dataset from Amazon S3?

Options:

A.

Define security group(s) to allow all HTTP inbound/outbound traffic and assign those security group(s) tothe Amazon SageMaker notebook instance.

B.

Сonfigure the Amazon SageMaker notebook instance to have access to the VPC. Grant permission in theKMS key policy to the notebook’s KMS role.

C.

Assign an IAM role to the Amazon SageMaker notebook with S3 read access to the dataset. Grantpermission in the KMS key policy to that role.

D.

Assign the same KMS key used to encrypt data in Amazon S3 to the Amazon SageMaker notebookinstance.

Question 35

A data scientist is using an Amazon SageMaker notebook instance and needs to securely access data stored in a specific Amazon S3 bucket.

Options:

A.

Add an S3 bucket policy allowing GetObject, PutObject, and ListBucket permissions to the Amazon SageMaker notebook ARN as principal.

B.

Encrypt the objects in the S3 bucket with a custom AWS Key Management Service (AWS KMS) key that only the notebook owner has access to.
