MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
An ML team uses SageMaker to deploy a model for real-time inference. They want to monitor and improve cost efficiency. Which THREE actions should they take? (Select THREE.)
⚠ Common exam trap
It's easy for candidates to confuse monitoring (Option C) with cost optimization, or they mistakenly apply Spot Training (Option D) to inference endpoints, not realizing that Spot instances are only supported for training and not for real-time inference due to interruption risk.
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 SageMaker Inference Recommender to find the optimal instance type and count
SageMaker Inference Recommender runs load tests against your model to generate instance type and count recommendations that balance performance and cost. By selecting the optimal configuration, you avoid over-provisioned instances that waste money or under-provisioned ones that degrade user experience, directly improving cost efficiency.
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 find the optimal instance type and count
Why this is correct
Inference Recommender provides recommendations to avoid over-provisioning.
- ✓
Enable auto-scaling to adjust the number of instances based on demand
Why this is correct
Auto-scaling ensures you only pay for capacity needed.
- ✗
Create a CloudWatch dashboard to monitor endpoint latency
Why it's wrong here
Monitoring latency is operational, not a direct cost optimization action.
- ✗
Use SageMaker Managed Spot Training for endpoint instances
Why it's wrong here
Spot instances are not supported for real-time endpoints.
- ✓
Purchase SageMaker Savings Plans for a discounted rate
Why this is correct
Savings Plans reduce cost in exchange for a usage commitment.
