- A
Attach a public endpoint with an SSL certificate and restrict access via IAM
Why wrong: Public endpoint contradicts no-internet requirement.
- B
Use a private subnet with a NAT Gateway and set EnableNetworkIsolation to True
Why wrong: NAT Gateway allows outbound internet, violating the no-outbound policy. NetworkIsolation prevents internet but not inter-container encryption.
- C
Deploy on a multi-model endpoint with encryption at rest using KMS
Why wrong: Does not address network isolation or inter-container encryption.
- D
Enable VPC-only mode for the endpoint and set EnableInterContainerTrafficEncryption to True
VPC-only removes public access and forces traffic through VPC; inter-container encryption secures container-to-container communication.

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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 financial services company needs to deploy a SageMaker endpoint that processes sensitive customer data. The security policy requires that all data in transit between the endpoint and the application must be encrypted, and that the endpoint cannot be accessed from the public internet. Additionally, model containers must not be able to initiate outbound internet requests. Which combination of settings meets these requirements?
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 VPC-only mode for the endpoint and set EnableInterContainerTrafficEncryption to True
Option D is correct because enabling VPC-only mode for the SageMaker endpoint ensures the endpoint is not accessible from the public internet, and setting EnableInterContainerTrafficEncryption to True encrypts data in transit between containers within the endpoint. This combination directly satisfies the requirements for no public internet access and encrypted data in transit, while the model containers are isolated from outbound internet requests by the VPC configuration.
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.
- ✗
Attach a public endpoint with an SSL certificate and restrict access via IAM
Why it's wrong here
Public endpoint contradicts no-internet requirement.
- ✗
Use a private subnet with a NAT Gateway and set EnableNetworkIsolation to True
- ✗
Deploy on a multi-model endpoint with encryption at rest using KMS
Why it's wrong here
Does not address network isolation or inter-container encryption.
- ✓
Enable VPC-only mode for the endpoint and set EnableInterContainerTrafficEncryption to True
Why this is correct
VPC-only removes public access and forces traffic through VPC; inter-container encryption secures container-to-container communication.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse EnableInterContainerTrafficEncryption with general data-in-transit encryption, overlooking that it only applies to inter-container traffic, while VPC-only mode is needed to block public internet access and prevent outbound requests.
Detailed technical explanation
How to think about this question
VPC-only mode for SageMaker endpoints uses an interface VPC endpoint (AWS PrivateLink) to route all traffic within the VPC, ensuring no public IP is assigned and the endpoint is only reachable via private IP addresses. EnableInterContainerTrafficEncryption leverages TLS 1.2 to encrypt traffic between model containers, which is critical when sensitive data flows through inference pipelines with multiple containers. In practice, this setup is often used in regulated industries like finance to meet PCI-DSS or SOC 2 requirements for data in transit and network isolation.
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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
