- A
Create a VPC with S3 VPC endpoints, attach a VPC-only policy to the SageMaker execution role, and enable KMS encryption for training jobs.
S3 VPC endpoints keep traffic within AWS network, and KMS encrypts data in transit and at rest.
- B
Use an S3 bucket with SSE-S3 encryption and restrict bucket access to a VPC.
Why wrong: SSE-S3 only encrypts at rest, not in transit; VPC restriction doesn't guarantee encryption in transit.
- C
Enable default encryption on the S3 bucket and use HTTPS for all SageMaker endpoints.
Why wrong: HTTPS encrypts in transit but does not keep traffic within the VPC; it may still go over the internet.
- D
Create a VPC with a NAT gateway, and configure SageMaker to use the VPC and enforce HTTPS.
Why wrong: NAT gateway allows outbound internet, which may expose traffic; HTTPS alone doesn't ensure no public internet traversal.
MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. 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 uses Amazon SageMaker to train and deploy machine learning models. The security team requires that all data in transit between the training job and S3 be encrypted, and that no data traverses the public internet. Which configuration should the company 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
Create a VPC with S3 VPC endpoints, attach a VPC-only policy to the SageMaker execution role, and enable KMS encryption for training jobs.
Option A is correct because it ensures that data in transit between SageMaker and S3 stays within the AWS network and is encrypted. By creating a VPC with S3 VPC endpoints, traffic uses AWS private IPs and never traverses the public internet. Attaching a VPC-only policy to the SageMaker execution role restricts the training job to only use VPC endpoints, and enabling KMS encryption for the training job ensures data is encrypted in transit (via TLS) and at rest.
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.
- ✓
Create a VPC with S3 VPC endpoints, attach a VPC-only policy to the SageMaker execution role, and enable KMS encryption for training jobs.
Why this is correct
S3 VPC endpoints keep traffic within AWS network, and KMS encrypts data in transit and at rest.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Use an S3 bucket with SSE-S3 encryption and restrict bucket access to a VPC.
Why it's wrong here
SSE-S3 only encrypts at rest, not in transit; VPC restriction doesn't guarantee encryption in transit.
- ✗
Enable default encryption on the S3 bucket and use HTTPS for all SageMaker endpoints.
Why it's wrong here
HTTPS encrypts in transit but does not keep traffic within the VPC; it may still go over the internet.
- ✗
Create a VPC with a NAT gateway, and configure SageMaker to use the VPC and enforce HTTPS.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse encryption in transit (HTTPS) with keeping traffic off the public internet, not realizing that HTTPS can still traverse the public internet unless a VPC endpoint or Direct Connect is used.
Detailed technical explanation
How to think about this question
S3 VPC endpoints use AWS PrivateLink, which creates a private connection between the VPC and S3 without requiring an internet gateway or NAT device. SageMaker training jobs can be configured to run in a VPC by specifying subnets and security groups, and the VPC-only policy on the execution role ensures that the SageMaker service only uses the VPC endpoint for S3 access, blocking any fallback to public S3 endpoints. This setup is critical for compliance with regulations like PCI DSS or HIPAA that mandate private network paths.
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.
