MLA-C01 Practice Question: ML Solution Monitoring, Maintenance, and Security
A team receives alerts that their SageMaker endpoint latency has increased significantly. They check CloudWatch metrics and see Invocations rising, but ModelLatency remains stable. Which metric should they investigate to find the source of the increased latency?
⚠ Common exam trap
Candidates often assume increased Invocations directly cause higher ModelLatency, but the exam tests the distinction between inference time and infrastructure overhead, leading them to incorrectly select ModelLatency instead of OverheadLatency.
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
✓
OverheadLatency
OverheadLatency measures the time taken by the SageMaker infrastructure to handle requests before and after model inference, including request routing, authentication, and response processing. Since ModelLatency is stable but total endpoint latency has increased, the extra time must be in the overhead component, making OverheadLatency the correct metric to investigate.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
OverheadLatency
Why this is correct
OverheadLatency captures infrastructure overhead; an increase here explains the total latency rise when ModelLatency is unchanged.
- ✗
ModelLatency
Why it's wrong here
ModelLatency is stable according to the scenario, so it is not the source of the increase.
- ✗
5XXError
Why it's wrong here
5XXError counts server errors; while it may correlate, it is not a latency metric.
- ✗
4XXError
Why it's wrong here
4XXError counts client errors; it does not directly affect latency.
