PCDOE Implementing service monitoring strategies Practice Question
You are designing a monitoring strategy for a cloud-native application. Which THREE components are essential for observability?
⚠ Common exam trap
Google Cloud often tests the distinction between the core observability data types (metrics, logs, traces) and the operational tools built on them (alerts, dashboards), trapping candidates who confuse 'observability components' with 'monitoring tools'.

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
✓
Metrics
Metrics (A) are essential because they provide quantitative, time-series data about system health and performance, such as CPU utilization, request latency, and error rates. In cloud-native observability, metrics are typically collected via Prometheus or similar systems, enabling trend analysis and threshold-based alerting. Without metrics, you cannot measure the overall state of your application or infrastructure over time.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Metrics
Why this is correct
Metrics provide quantitative data about system performance.
- ✗
Alerts
Why it's wrong here
Alerts are a result of observability, not a core pillar.
- ✗
Dashboards
Why it's wrong here
Dashboards visualize data but are not a foundational pillar.
- ✓
Traces
Why this is correct
Traces track request flows across distributed systems.
- ✓
Logs
Why this is correct
Logs provide detailed records of events and errors.
