MLA-C01 Practice Question: A team wants to apply a custom container for…
A team wants to apply a custom container for inference on SageMaker. The container needs to implement a web server that responds to API requests. Which protocol and port must the container listen on to be compatible with SageMaker hosting?
⚠ Common exam trap
Test-takers frequently assume SageMaker requires HTTPS for security, but the service actually handles encryption externally, so the container must use plain HTTP on port 8080.
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
✓
The container must listen on port 8080 and use HTTP protocol.
SageMaker requires custom inference containers to listen on port 8080 and communicate over HTTP (not HTTPS). The SageMaker hosting service uses a proxy that terminates HTTPS and forwards plain HTTP requests to the container on port 8080. This ensures compatibility with the built-in model serving infrastructure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The container must listen on port 8080 and use HTTPS protocol.
Why it's wrong here
SageMaker uses HTTP, not HTTPS for internal communication.
- ✓
The container must listen on port 8080 and use HTTP protocol.
Why this is correct
SageMaker expects HTTP on port 8080 for /invocations and /ping.
- ✗
The container can listen on any port as long as the port is specified in the endpoint configuration.
Why it's wrong here
SageMaker only supports port 8080 for inference containers.
- ✗
The container must listen on port 8000 and use HTTP protocol.
Why it's wrong here
SageMaker uses port 8080 by default.
