Where should you store custom inference container images?
Why B is the answer
Amazon Elastic Container Registry
ECR stores container images that SageMaker AI pulls.
In detail
- Amazon ECR stores container images.
- Grant the execution role permission to pull.
Use case
An illustrative scenario, not a real incident.
A team stores its custom inference image in Amazon ECR, and SageMaker AI pulls it at deployment.

Key point: ECR stores container images.
Why the other options are wrong
- A. Amazon S3 Glacier
- Glacier is archive storage.
- C. SageMaker Model Registry
