The answer is that no additional configuration is needed because SageMaker real-time endpoints are automatically served over HTTPS. This is the correct choice because AWS SageMaker endpoints use TLS encryption by default for all traffic between the client application and the endpoint, ensuring encryption in transit without any manual setup. On the AWS Certified Machine Learning Engineer Associate MLA-C01 exam, this concept tests your understanding of SageMaker’s built-in security features versus common misconceptions—many candidates mistakenly think they need to configure a VPC, AWS Certificate Manager, or AWS KMS for in-transit encryption, but those services address network isolation, certificate management, or encryption at rest, respectively. The key trap is confusing encryption in transit with encryption at rest; remember that SageMaker endpoints handle HTTPS automatically, while KMS is for data at rest. A helpful memory tip is "HTTPS is default, no extra effort"—if the question asks about encrypting traffic between client and endpoint, the answer is always the default HTTPS.
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 uses an Amazon SageMaker endpoint for real-time inference. The security team requires that all traffic between the endpoint and the client application be encrypted in transit. Which configuration ensures this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The endpoint is automatically served over HTTPS; no additional configuration is needed.
Option B is correct because SageMaker endpoints are already HTTPS-enabled by default, providing encryption in transit via TLS. Option A is wrong because a VPC does not provide encryption in transit by default; it provides network isolation. Option C is wrong because SageMaker does not directly use AWS Certificate Manager for endpoint encryption; it uses AWS-managed certificates. Option D is wrong because AWS KMS is for encryption at rest, not in transit.
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.
✗
Deploy the endpoint in a VPC and use VPC Endpoints.
Why it's wrong here
VPC provides network isolation but not encryption in transit by default.
✗
Use AWS Key Management Service (KMS) to encrypt the data in transit.
Read the scenario before looking for a memorised answer.
✗
Attach an AWS Certificate Manager (ACM) certificate to the endpoint.
Why it's wrong here
SageMaker manages its own certificates; you cannot attach ACM certificates directly.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
