MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A financial services company deploys a fraud detection model with a SageMaker endpoint. They need to ensure that all data sent to the endpoint is encrypted in transit and at rest, and that the endpoint cannot be accessed from the public internet. Which combination of settings should they use?
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, inter-container traffic encryption, and use a KMS key for endpoint encryption
VPC-only mode ensures the endpoint is private. Inter-container traffic encryption is needed for data in transit between containers in multi-model endpoints. KMS encryption secures data at rest on the instance storage.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Use endpoint data encryption with an AWS managed key and enable public endpoint access
Why it's wrong here
Public access violates the requirement of no public internet access.
- ✗
Enable inter-container traffic encryption and disable VPC-only mode
Why it's wrong here
VPC-only mode is required to block public internet access.
- ✓
Enable VPC-only mode, inter-container traffic encryption, and use a KMS key for endpoint encryption
Why this is correct
VPC-only isolates the endpoint; inter-container encryption secures traffic; KMS encrypts data at rest.
- ✗
Deploy the endpoint in a private subnet without SageMaker VPC-only mode
Why it's wrong here
Without VPC-only mode, the endpoint may still have a public endpoint.
