A company wants to build an ML model by using Amazon SageMaker.

Amazon SageMaker Feature Store is the correct solution for sharing and managing variables (features) across multiple teams during model development.

Amazon SageMaker Feature Store:

A fully managed repository for storing, sharing, and managing machine learning features across different teams and models.

It enables collaboration and reuse of features, ensuring consistent data usage and reducing redundancy.

Why Option A is Correct:

Centralized Feature Management: Provides a central repository for managing features, making it easier to share them across teams.

Collaboration and Reusability: Improves efficiency by allowing teams to reuse existing features instead of creating them from scratch.

Why Other Options are Incorrect:

B. SageMaker Data Wrangler: Helps with data preparation and analysis but does not provide a centralized feature store.

C. SageMaker Clarify: Used for bias detection and explainability, not for managing variables across teams.

D. SageMaker Model Cards: Provide model documentation, not feature management.
