- A
Attach a resource-based policy to the SageMaker model granting access to the external account
Resource-based policies allow cross-account access to SageMaker models without sharing secrets.
- B
Create a new SageMaker execution role in the company account and grant the external account's IAM role permission to pass it
The external team needs to pass the execution role when creating endpoints; the pass role permission must be granted.
- C
Create an IAM role in the company account and share the credentials with the external team
Why wrong: Sharing long-term credentials is insecure and against best practices; cross-account roles should be used.
- D
Provide the external team with the company's AWS account root user credentials
Why wrong: Root credentials should never be shared; this is a severe security risk.
- E
Set up a VPN connection between the two accounts for network access
Why wrong: VPN is unnecessary for cross-account IAM access; it adds complexity without addressing authentication.
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 needs to give a data science team from another AWS account access to deploy models to a SageMaker endpoint in the company's account. The company wants to minimize administrative overhead while ensuring security. Which TWO steps should the company take? (Select TWO.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 granting access to the external account
Option A is correct because SageMaker models support resource-based policies that allow cross-account access. By attaching a resource-based policy to the SageMaker model, the company can grant the external AWS account's IAM role the necessary permissions to deploy the model to the endpoint without needing to manage additional IAM roles or share credentials. This approach minimizes administrative overhead by leveraging AWS's built-in cross-account access mechanism.
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
The trap here is that candidates often confuse resource-based policies with IAM roles, thinking that creating a new execution role and granting pass-role permissions is the only way to achieve cross-account access, when in fact SageMaker models support direct resource-based policies that simplify the setup.
Detailed technical explanation
How to think about this question
Resource-based policies for SageMaker models allow you to specify a principal (e.g., an external AWS account) that can invoke actions like `sagemaker:CreateEndpoint` or `sagemaker:InvokeEndpoint`. Under the hood, AWS evaluates these policies along with the caller's IAM permissions; the external account's IAM role must also have a trust policy that allows the SageMaker service to assume it. In a real-world scenario, this is commonly used for multi-account ML pipelines where a central data science team deploys models to production accounts, avoiding the need for cross-account role assumption chains.
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.
TExam Day Tips
- 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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
