AWS Certified AI Practitioner AIF-C01 Practice Question

Amazon SageMaker lets you encrypt the EBS volume that backs a training instance by specifying an AWS Key Management Service (KMS) key. SageMaker uses the key to perform transparent, at-rest encryption of the ML storage volume, ensuring the training data is protected without changes to the code or workflow. S3 Transfer Acceleration only improves transfer speed and provides no volume encryption. AWS Shield Standard mitigates DDoS attacks and does not encrypt storage. Placing data in S3 Glacier Deep Archive is meant for long-term archival and does not affect how data is stored on the training volume. Therefore, providing a KMS key for SageMaker volume encryption is the correct solution.
