- A
Use AWS PrivateLink to expose the SageMaker endpoint privately and grant access via security groups
Why wrong: PrivateLink enables VPC access but does not handle cross-account authorization; IAM/resource policies are needed.
- B
Attach a resource-based policy to the SageMaker endpoint that grants the other account's IAM role invoke permissions
Resource-based policies allow cross-account access to the endpoint. The other account's IAM role must have sts:AssumeRole or be allowed by the policy.
- C
Create an IAM role in the source account and share the role ARN with the target account
Why wrong: Sharing a role ARN does not grant access; the target account would need to assume that role, which requires cross-account trust policies.
- D
Share the model artifacts via an S3 bucket with cross-account bucket policies and let the other account deploy independently
Why wrong: This does not allow direct inference access to the endpoint; the other account would need to deploy its own copy.
MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
This MLA-C01 practice question tests your understanding of ml solution monitoring, maintenance, and security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to allow a SageMaker model in one AWS account to be accessed by a different AWS account for inference. They need to maintain security and compliance. Which approach meets the requirement?
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 endpoint that grants the other account's IAM role invoke permissions
Cross-account access can be achieved by using resource-based policies on the SageMaker model or endpoint, combined with appropriate IAM roles in the consuming account.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- 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.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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.
