PMLE Monitoring ML Solutions Practice Question
An ML engineer is troubleshooting why a Vertex AI Endpoint is returning high prediction latency. They have enabled request/response logging and see that some requests take >1 second while most are fast. Which THREE actions should they take to diagnose the issue?
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
✓
Check CPU and GPU utilisation metrics on the endpoint.
Check Cloud Monitoring metrics for p99 latency trends, CPU/GPU utilisation to identify bottlenecks, and review request/response logs for patterns (e.g., large payloads causing slow inference).
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Check CPU and GPU utilisation metrics on the endpoint.
Why this is correct
High utilisation can indicate resource bottleneck.
- ✓
Review the request/response logs in BigQuery to identify if large payloads correlate with high latency.
Why this is correct
Logs can show payload size and latency per request.
- ✗
Disable Vertex AI Model Monitoring to reduce overhead.
Why it's wrong here
Monitoring overhead is minimal and not the cause of high latency.
- ✓
Check the p99 latency metric in Cloud Monitoring.
Why this is correct
Essential to confirm the latency issue.
- ✗
Increase the number of replicas to resolve the issue immediately.
Why it's wrong here
Scaling without diagnosis may not address root cause; should diagnose first.
