The correct answer is to enable HTTPS for encryption in transit, enable encryption at rest for the endpoint’s attached storage, and attach an IAM policy to the endpoint to allow only authorized principals. These three steps directly address the core requirements of SageMaker endpoint security: encrypting sensitive data both in transit and at rest while controlling access via AWS IAM. HTTPS ensures data is encrypted during transmission between clients and the endpoint, while server-side encryption for the ML storage volume protects data at rest. The IAM policy, attached to the endpoint configuration, restricts invocation to only those principals with explicit permissions, preventing unauthorized access. On the AWS Certified Machine Learning Specialty MLS-C01 exam, this question tests your understanding of the shared responsibility model for SageMaker endpoints and common missteps like confusing VPC isolation with encryption or choosing SSE-S3 over SSE-KMS for stricter compliance. A useful memory tip is “HTTPS, SSE, and IAM—three pillars of endpoint security.”
MLS-C01 Practice Question: Machine Learning Implementation and Operations
This MLS-C01 practice question tests your understanding of machine learning implementation and operations. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 is deploying a machine learning model to an Amazon SageMaker endpoint. The model receives requests with sensitive data that must be encrypted in transit and at rest. Additionally, the company needs to control access to the endpoint using AWS IAM. Which THREE steps should the company take to meet these requirements? (Choose THREE.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable HTTPS for the endpoint
Options A, B, and D are correct. Enabling encryption in transit using HTTPS, enabling encryption at rest for the endpoint's attached storage, and attaching an IAM policy to the endpoint to allow only authorized users are necessary. Option C is wrong because VPC settings do not encrypt data at rest. Option E is wrong because the model data in S3 should be encrypted with SSE-KMS, not SSE-S3, to meet stricter security requirements.
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.
Read the scenario before looking for a memorised answer.
✗
Configure the endpoint to use a VPC
Why it's wrong here
VPC provides network isolation, not encryption.
✗
Store the model artifacts in Amazon S3 with SSE-S3 encryption
Why it's wrong here
SSE-S3 is less secure; SSE-KMS is preferred for sensitive data.
✓
Enable encryption at rest for the endpoint's ML storage volume
Why this is correct
Encryption at rest protects data stored on the endpoint.

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.
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.
