- A
Set the notebook instance's Direct Internet Access to disabled and use IAM authentication.
Why wrong: Direct Internet Access controls internet connectivity, not notebook access.
- B
Grant the specific IAM role permission to call sagemaker:CreatePresignedNotebookInstanceUrl on that notebook instance.
This action generates a presigned URL for accessing the notebook, and restricting it to the role enforces access control.
- C
Use AWS Systems Manager to proxy SSH access, then use IAM permission.
Why wrong: Systems Manager is for SSH, but notebook instances use JupyterLab via presigned URL.
- D
Configure the notebook instance to use a VPC and restrict access via security groups.
Why wrong: VPC and security groups control network access, not IAM user/role access.

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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 restrict access to a SageMaker notebook instance so that only a specific IAM role can open the notebook via JupyterLab. The notebook instance is associated with a lifecycle configuration that installs custom packages. What is the correct way to enforce access control?
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
✓
Grant the specific IAM role permission to call sagemaker:CreatePresignedNotebookInstanceUrl on that notebook instance.
Option B is correct because the `sagemaker:CreatePresignedNotebookInstanceUrl` API action generates a URL that provides authenticated access to the notebook instance's JupyterLab interface. By granting this permission only to the specific IAM role, you ensure that only that role can call the API and obtain the presigned URL, effectively restricting access to the notebook. This is the native, recommended way to control access to a SageMaker notebook instance without relying on network-level controls or SSH proxies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the notebook instance's Direct Internet Access to disabled and use IAM authentication.
Why it's wrong here
Direct Internet Access controls internet connectivity, not notebook access.
- ✓
Grant the specific IAM role permission to call sagemaker:CreatePresignedNotebookInstanceUrl on that notebook instance.
Why this is correct
This action generates a presigned URL for accessing the notebook, and restricting it to the role enforces access control.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Use AWS Systems Manager to proxy SSH access, then use IAM permission.
Why it's wrong here
Systems Manager is for SSH, but notebook instances use JupyterLab via presigned URL.
- ✗
Configure the notebook instance to use a VPC and restrict access via security groups.
Why it's wrong here
VPC and security groups control network access, not IAM user/role access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-level controls (VPC, security groups, disabling internet access) with identity-based access control, mistakenly thinking that restricting network access is sufficient to prevent unauthorized users from opening the notebook, when in fact the presigned URL API is the only mechanism that ties JupyterLab access to a specific IAM role.
Detailed technical explanation
How to think about this question
Under the hood, `CreatePresignedNotebookInstanceUrl` returns a URL that is signed with the caller's IAM credentials and includes a session token; this URL is valid for a limited time (default 12 hours) and can only be generated by a principal with the explicit `sagemaker:CreatePresignedNotebookInstanceUrl` permission. A real-world scenario where this matters is when you have multiple data scientists sharing a single notebook instance but need to audit who accessed it; by restricting the API to a specific role, you can use CloudTrail to log every URL generation event. A subtle behavior is that the presigned URL itself does not enforce MFA or session policies beyond the caller's IAM session, so you should combine this with a condition key like `aws:SourceArn` or `aws:RequestedRegion` for additional security.
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.
