KCNA Cloud Native Observability Practice Question
Which TWO are pillars of observability? (Select two.)
⚠ Common exam trap
CNCF often tests the distinction between the pillars of observability (Logs, Metrics, Traces) and the tools or outputs derived from them (e.g., SLIs, Alerting, Dashboards), leading candidates to confuse operational practices with foundational data types.

Correct answer & explanation
✓
Logs
Logs and Metrics are two of the three pillars of observability (alongside Traces). Logs provide immutable, timestamped records of discrete events, while Metrics are numeric aggregations of data over time (e.g., Prometheus counters, histograms). Together they form the foundation for understanding system behavior in cloud-native environments.
