MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
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?
⚠ Common exam trap
Candidates often 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.
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
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.
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
Why it's wrong here
NAT Gateway allows outbound internet, violating the no-outbound policy. NetworkIsolation prevents internet but not inter-container encryption.
- ✗
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.
