PCA › Observability Concepts
Observability Concepts is the foundational PCA domain covering metrics, logs, and traces, the Prometheus data model, and why cardinality matters. Questions are scenario-based: you diagnose memory spikes from unbounded labels, explain label purpose, and reason about alerting philosophy and monitoring goals rather than recalling configuration syntax.
