- A
Specify the KMS key as the VolumeKmsKeyId and OutputKmsKeyId in the training job configuration
This ensures that the training volume and output are encrypted with the same key.
- B
Enable inter-container traffic encryption
Why wrong: This encrypts traffic between containers, not data at rest.
- C
No additional configuration is required because S3 SSE-KMS automatically applies
Why wrong: S3 encryption does not automatically encrypt the SageMaker training volume or output.
- D
Use network isolation mode
Why wrong: Network isolation restricts internet access, not encryption.

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 security team requires that all data used by a SageMaker training job be encrypted at rest using a customer-managed KMS key. The data is stored in an S3 bucket that is already encrypted with SSE-KMS. What additional configuration is needed on the SageMaker training job?
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
✓
Specify the KMS key as the VolumeKmsKeyId and OutputKmsKeyId in the training job configuration
When the input data is encrypted with a customer-managed KMS key, you must specify the same KMS key in the VolumeKmsKeyId parameter of the training job to encrypt the ML storage volume, and also set the OutputKmsKeyId for output encryption.
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.
- ✓
Specify the KMS key as the VolumeKmsKeyId and OutputKmsKeyId in the training job configuration
Why this is correct
This ensures that the training volume and output are encrypted with the same key.

Network isolation restricts internet access, not encryption.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
S3 encryption does not automatically encrypt the SageMaker training volume or output.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
