- A
Use a private link to connect Studio to the VPC
Why wrong: PrivateLink provides connectivity but does not block internet access by itself.
- B
Enable network isolation mode for the Studio domain
Why wrong: Network isolation is a per-model setting, not a Studio domain setting.
- C
Attach a security group that blocks all outbound traffic
Why wrong: Security groups alone cannot fully enforce VPC-only mode for Studio.
- D
Configure the Studio domain with VPC-only mode and disable direct internet access
VPC-only mode ensures Studio resources run within a VPC without internet access, meeting the requirement.

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 machine learning team is using SageMaker Studio for model development. They need to restrict all internet access from Studio notebooks and ensure that all data stays within a VPC. Which configuration should they use?
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
✓
Configure the Studio domain with VPC-only mode and disable direct internet access
Option D is correct because configuring a SageMaker Studio domain with VPC-only mode and disabling direct internet access ensures that all Studio notebook traffic stays within the VPC and has no route to the public internet. This is the only configuration that both restricts internet access and enforces data residency within the VPC by using VPC-only networking, which does not rely on an internet gateway or NAT gateway for outbound traffic.
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 network isolation mode (which applies only to training/inference containers) with VPC-only mode for Studio notebooks, or they incorrectly assume that a security group blocking all outbound traffic is a valid way to restrict internet access while still allowing necessary AWS API calls.
Detailed technical explanation
How to think about this question
VPC-only mode in SageMaker Studio creates a network configuration where the Studio domain uses only VPC IP addresses and does not assign public IPs to the notebook instances, effectively eliminating any path to the internet. Under the hood, this mode requires the VPC to have VPC endpoints (e.g., for SageMaker API, SageMaker Runtime, and S3) so that all AWS service calls stay within the AWS network, and it disables the default internet gateway route for the Studio subnets. A real-world scenario where this matters is in regulated industries like healthcare or finance, where data must never leave the VPC boundary, and VPC-only mode ensures compliance without relying on restrictive security groups that could break essential services.
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.
