- A
Use SageMaker Studio with public internet access and enable AWS WAF
Why wrong: Public access does not restrict to corporate network; WAF is for web application firewall, not network restriction.
- B
Place SageMaker Studio in a public subnet and use security groups to restrict access
Why wrong: Public subnet exposes Studio to internet; security groups alone do not guarantee VPC-only access.
- C
Enable SageMaker Studio in VPC-only mode and use a KMS key for data encryption
VPC-only mode restricts access to the VPC; KMS encryption secures data at rest.
- D
Use IAM policies to allow only corporate IP addresses and enable encryption at rest with an S3 bucket key
Why wrong: IAM policies cannot restrict network access at the VPC level; S3 bucket key is not sufficient for all Studio data.
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 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?
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
Option C is correct because 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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.

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.

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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that 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.
Detailed technical explanation
How to think about this question
SageMaker Studio in VPC-only mode uses an interface VPC endpoint (AWS PrivateLink) to connect Studio to the VPC, ensuring no traffic traverses the public internet. The KMS key encrypts the Studio's EFS file system, SageMaker notebook instances, and model artifacts, with encryption at rest enforced by default when a KMS key is specified. In a real-world scenario, this setup is critical for regulated industries like healthcare or finance, where data must never leave the corporate network and must be encrypted with customer-managed keys for compliance with standards like HIPAA or PCI DSS.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
