MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company wants to enable cross-account access to a SageMaker model endpoint. The model is in Account A, and Account B needs to invoke it. Which TWO steps are required? (Select TWO)
⚠ Common exam trap
Many candidates confuse network-level connectivity (VPC peering) with IAM-level authorization, or assume that cross-account access requires duplicating resources, when in fact SageMaker's resource-based policies provide a direct and secure solution.
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
✓
Attach a resource-based policy to the SageMaker model in Account A allowing access from Account B's IAM role
SageMaker endpoints support resource-based policies that allow cross-account access. By attaching a resource-based policy to the model endpoint in Account A, you can grant the IAM role from Account B explicit permission to invoke the endpoint. This is the standard AWS mechanism for cross-account SageMaker endpoint invocation without needing to duplicate the model.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Attach a resource-based policy to the SageMaker model in Account A allowing access from Account B's IAM role
Why this is correct
Resource policies grant cross-account permissions directly on the model.
- ✗
Export the model from Account A and re-deploy in Account B
Why it's wrong here
This duplicates the model unnecessarily.
- ✓
Create an IAM role in Account B with permissions to invoke SageMaker endpoints
Why this is correct
The IAM role in Account B must have sts:AssumeRole and sagemaker:InvokeEndpoint permissions.
- ✗
Configure VPC peering between the two accounts
Why it's wrong here
VPC peering is not required for API access; resource policies suffice.
- ✗
Use a SageMaker notebook instance cross-account sharing
Why it's wrong here
Notebook sharing is for development, not inference access.
