MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company uses SageMaker Studio for collaborative ML development. The security team requires that all SageMaker Studio notebooks run within a VPC and cannot access the public internet. Which configuration should the administrator set?
⚠ Common exam trap
Watch out — candidates often confuse VPC-only mode with simply using a private subnet, but VPC-only mode is a specific SageMaker Studio domain setting that explicitly blocks all internet access, whereas a private subnet alone could still allow outbound traffic via a NAT Gateway or VPC endpoint.
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
✓
Enable VPC-only mode for the SageMaker Studio domain
Enabling VPC-only mode for the SageMaker Studio domain ensures that all Studio notebooks and apps are launched within the specified VPC and cannot access the public internet. This mode enforces that all network traffic, including internet-bound traffic, is routed through the VPC, and it blocks direct internet access by default, meeting the security team's requirement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable VPC-only mode for the SageMaker Studio domain
Why this is correct
This restricts all traffic to the VPC, no internet access.
- ✗
Use SageMaker notebook instances instead of Studio
Why it's wrong here
Notebook instances can also be VPC-only but the question specifies Studio.
- ✗
Apply an SCP that denies internet access for all IAM users
Why it's wrong here
SCP is at account level but does not control network configuration of Studio.
- ✗
Set the SageMaker Studio domain to use a public subnet with a NAT Gateway
Why it's wrong here
NAT Gateway allows outbound internet, violating the no-internet policy.
