MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A company wants to implement cost monitoring and optimization for SageMaker endpoints. Which TWO actions should they take? (Select TWO)
⚠ Common exam trap
Many candidates confuse cost monitoring (Option B) with cost optimization, or assume that Model Monitor (Option D) directly reduces costs when it only monitors quality, not spend.
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 Savings Plans to get discounted rates in exchange for a commitment
SageMaker Savings Plans offer discounted compute rates (up to 64% off on-demand) in exchange for a 1- or 3-year commitment to a consistent amount of compute usage (measured in dollars per hour), directly reducing endpoint costs. This is a cost optimization mechanism, not a monitoring one, and aligns with the goal of reducing spend on SageMaker endpoints.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually scale instances based on historical patterns
Why it's wrong here
Manual scaling is less efficient than auto-scaling or Inference Recommender.
- ✗
Enable detailed billing reports to track endpoint costs
Why it's wrong here
Detailed billing reports are available but not an optimization action.
- ✓
Use SageMaker Savings Plans to get discounted rates in exchange for a commitment
Why this is correct
Savings Plans provide lower costs for consistent usage.
- ✗
Use SageMaker Model Monitor to reduce endpoint costs
Why it's wrong here
Model Monitor does not directly reduce costs; it monitors quality.
- ✓
Right-size endpoints using SageMaker Inference Recommender
Why this is correct
Inference Recommender suggests optimal instance types and configurations.
