Selected Answer: D
D. Using the SageMaker Feature Store GetRecord API with the record identifier1. This API allows customers to retrieve features from a single feature group and access one record per API call2. The record identifier is a unique value that identifies a record within a feature group1. The GetRecord API returns the latest version of the record by default1. This solution avoids the need to use additional queries or filters to find the latest record.
