MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company needs to ensure that their SageMaker Studio environment is only accessible from within their corporate network and that all data processed in Studio remains encrypted. Which configuration should they use?
⚠ Common exam trap
Candidates often confuse network-level access control (VPC-only mode) with API-level access control (IAM policies), or assume that security groups alone can restrict access to a public subnet, ignoring that public subnets inherently have internet connectivity.
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 SageMaker Studio in VPC-only mode and use a KMS key for data encryption
Enabling SageMaker Studio in VPC-only mode ensures that the Studio environment is accessible only from within the corporate network by routing all traffic through a VPC with no public internet access. Additionally, using a KMS key for data encryption provides customer-managed encryption for data at rest and in transit within the Studio environment, meeting the encryption 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.
- ✗
Use SageMaker Studio with public internet access and enable AWS WAF
Why it's wrong here
Public access does not restrict to corporate network; WAF is for web application firewall, not network restriction.
- ✗
Place SageMaker Studio in a public subnet and use security groups to restrict access
Why it's wrong here
Public subnet exposes Studio to internet; security groups alone do not guarantee VPC-only access.
- ✓
Enable SageMaker Studio in VPC-only mode and use a KMS key for data encryption
Why this is correct
VPC-only mode restricts access to the VPC; KMS encryption secures data at rest.
- ✗
Use IAM policies to allow only corporate IP addresses and enable encryption at rest with an S3 bucket key
Why it's wrong here
IAM policies cannot restrict network access at the VPC level; S3 bucket key is not sufficient for all Studio data.
