A company needs to give a data science team in another AWS account access to deploy a model from a shared model registry. Which approach should they use to grant cross-account access?
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 model registry granting the other account access
Resource-based policies (also called resource policies) can be attached to the model registry to allow cross-account access. IAM roles are used for intra-account access, not for granting access to resources in another account.
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 other account with permissions to access the registry
Why it's wrong here
The IAM role in the other account must be assumed, but the registry must also allow access via a resource policy or trust policy.
- ✗
Use AWS Organizations SCP to allow cross-account access
Why it's wrong here
SCPs are used to set permission boundaries, not to grant specific cross-account access.
- ✗
Share the model artifacts via Amazon S3 bucket policy and use an IAM role
Why it's wrong here
S3 bucket policies can share model artifacts, but the model registry access must still be granted separately.
- ✓
Attach a resource-based policy to the model registry granting the other account access
Why this is correct
Resource-based policies allow cross-account access to SageMaker resources like the model registry.
