MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company uses SageMaker JumpStart to deploy a foundation model for a summarization task. They want to minimize costs while still meeting a latency requirement of under 2 seconds. Which option should they consider?
⚠ Common exam trap
A common misconception is that serverless endpoints are always the cheapest option, but for latency-sensitive workloads with large models, the cold-start overhead and lack of guaranteed compute resources make them unsuitable. Inference Recommender is the correct tool for cost-latency trade-off analysis.

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 SageMaker Inference Recommender to select the cheapest instance that meets latency
SageMaker Inference Recommender runs load tests against your model on various instance types and provides latency and cost metrics. By selecting the cheapest instance that still meets the sub-2-second latency requirement, you directly minimize cost while satisfying the performance constraint. This is the most systematic and cost-effective approach for this scenario.
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 SageMaker Inference Recommender to select the cheapest instance that meets latency
Why this is correct
Inference Recommender benchmarks the model on different instances to find the optimal balance of cost and latency.
- ✗
Deploy the model on a serverless endpoint
Why it's wrong here
Serverless endpoints may have cold starts and limited GPU support, potentially exceeding latency requirements.
- ✗
Enable auto-scaling to handle variable traffic
Why it's wrong here
Auto-scaling manages traffic but does not directly optimize instance type cost.
- ✗
Use the largest GPU instance to ensure fast inference
Why it's wrong here
Largest instance may exceed latency requirements but is not cost-effective.
