MLA-C01 Practice Question: Deploy a machine learning model that makes…
A company wants to deploy a machine learning model that makes real-time predictions for a mobile app. The model is a deep neural network with a large model size (500 MB). Which SageMaker endpoint configuration is most cost-effective while meeting low-latency requirements?
⚠ Common exam trap
The MLA-C01 exam often tests the misconception that multi-model endpoints are always more cost-effective for large models, but the trap here is that multi-model endpoints introduce significant latency from disk I/O for models over 100 MB, making them unsuitable for real-time inference despite lower instance costs.
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
✓
Real-time endpoint with a single instance
A real-time endpoint with a single instance provides the lowest latency for a 500 MB deep neural network model, as it keeps the model loaded in memory and ready for inference without cold starts or multi-model overhead. This configuration is also cost-effective for consistent traffic patterns, as you pay for the instance uptime rather than per-invocation or for multiple model loads.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Multi-model endpoint
Why it's wrong here
Designed to host multiple models on one instance, not optimal for a single large model.
- ✗
Serverless inference
Why it's wrong here
Serverless may introduce cold start latency and is better for intermittent traffic, not consistent low latency.
- ✓
Real-time endpoint with a single instance
Why this is correct
Ensures low latency and is cost-effective for a single model with sustained traffic.
- ✗
Batch transform
Why it's wrong here
Batch transform is for offline predictions, not real-time.
