- B
Use AWS Organizations SCP to allow cross-account access
Why wrong: SCPs are used to set permission boundaries, not to grant specific cross-account access.
- C
Share the model artifacts via Amazon S3 bucket policy and use an IAM role
Why wrong: S3 bucket policies can share model artifacts, but the model registry access must still be granted separately.
- D
Attach a resource-based policy to the model registry granting the other account access
Resource-based policies allow cross-account access to SageMaker resources like the model registry.

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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.

Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
