AIF-C01 Practice Question: Security, Compliance, and Governance for AI Solutions
A company needs to ensure that model inference endpoints in SageMaker are only accessible from a private subnet in their VPC, and no traffic goes over the public internet. Which network configuration 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
✓
Use a VPC interface endpoint for SageMaker and disable public access
A VPC-only endpoint (interface endpoint) or private endpoint without public internet access ensures traffic stays within the VPC.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Create a public endpoint and restrict access using IAM policies
Why it's wrong here
Public endpoint still uses internet; IAM does not prevent internet exposure.
- ✗
Use AWS PrivateLink for the endpoint, but keep public endpoint enabled
Why it's wrong here
PrivateLink provides private connectivity, but leaving public endpoint enabled allows internet traffic.
- ✓
Use a VPC interface endpoint for SageMaker and disable public access
Why this is correct
An interface endpoint connects SageMaker to the VPC privately, and disabling public access ensures no internet traffic.
- ✗
Deploy the endpoint in a public subnet with a security group blocking all inbound traffic
Why it's wrong here
Public subnet implies internet gateway; security group cannot block outbound internet entirely.
