MLS-C01 Modeling Practice Question
Network Topology
A data scientist is deploying a SageMaker model using CloudFormation. The stack creation fails with the above error. What is the MOST likely cause?
⚠ Common exam trap
Many exam-takers confuse a missing image (resource not found) with an IAM permissions error, but the error message for a missing image is distinct and occurs at a different stage of the API call.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Docker image has not been pushed to the ECR repository
The error indicates that SageMaker cannot find the Docker image specified in the `PrimaryContainer` of the model definition. CloudFormation creates the SageMaker model by referencing an ECR image URI; if that image has not been pushed to the specified ECR repository, the model creation fails immediately. This is the most common cause when the stack creation fails with an error about a missing or inaccessible image.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The Docker image has not been pushed to the ECR repository
Why this is correct
The error clearly states the image does not exist in ECR.
- ✗
The IAM role does not have permissions to access ECR
Why it's wrong here
An IAM permission error would have a different message.
- ✗
The model name is incorrect
Why it's wrong here
The error is about the container image, not the model name.
- ✗
The instance type specified in the endpoint configuration is not available
Why it's wrong here
The error is about the container image, not the instance type.
