MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company deploys a model in a different AWS account for production. They want to allow the production account to invoke the model endpoint from a SageMaker notebook in the same account, while keeping the model in the original account. Which configuration is required?
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 policy to the SageMaker model in the model account that grants invoke permissions to the production account's IAM role
Cross-account model access requires a resource policy on the model in Account A that grants invoke permissions to Account B. The production account's execution role must also have permission to invoke the model. SageMaker Model Registry does not handle cross-account inference. VPC peering is not sufficient for IAM permissions. IAM role cross-account trust is needed but the model resource policy is also necessary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create an IAM role in the production account with cross-account trust to assume a role in the model account
Why it's wrong here
This allows the production account to assume a role but does not grant access to the model resource itself.
- ✗
Use SageMaker Model Registry to share the model across accounts
Why it's wrong here
Model Registry manages versions, not cross-account inference access.
- ✗
Set up VPC peering between the two accounts and use private DNS
Why it's wrong here
VPC peering provides network connectivity but does not grant IAM permissions for cross-account access.
- ✓
Attach a resource policy to the SageMaker model in the model account that grants invoke permissions to the production account's IAM role
Why this is correct
Resource policy on the model allows cross-account invocation when combined with proper IAM permissions.
