PCDOE Implementing service monitoring strategies Practice Question
Which TWO of the following are best practices for implementing service monitoring in Google Cloud? (Choose 2)
⚠ Common exam trap
Google Cloud often tests the distinction between resource-level monitoring (USE method) and service-level monitoring (RED method), trapping candidates who apply the USE method to services or confuse cause-based alerts with symptom-based alerts.

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 Cloud Monitoring uptime checks to verify that services are reachable from external locations.
Cloud Monitoring uptime checks verify that a service is reachable from external locations by sending HTTP, HTTPS, or TCP requests from Google Cloud's global vantage points. This validates external availability and helps detect regional outages or DNS resolution issues, which is a core best practice for service monitoring.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set static alert thresholds without considering historical baselines.
Why it's wrong here
Thresholds should be based on baselines, not static values.
- ✓
Use Cloud Monitoring uptime checks to verify that services are reachable from external locations.
Why this is correct
Uptime checks verify external accessibility.
- ✗
Use the USE method (Utilization, Saturation, Errors) for service-level monitoring.
Why it's wrong here
USE is for resource monitoring, not services.
- ✓
Define service level indicators (SLIs) using the RED method (Rate, Errors, Duration).
Why this is correct
RED metrics are a best practice for service monitoring.
- ✗
Alert on cause-based metrics (e.g., CPU utilization) rather than symptom-based metrics (e.g., latency).
Why it's wrong here
Alert on symptoms, not causes.
