Kubernetes and Cloud Native Associate (KCNA) — Question 129

What are the 3 pillars of Observability?

Answer options

• A. Metrics, Logs, and Traces
• B. Metrics, Logs, and Spans
• C. Metrics, Data, and Traces
• D. Resources, Logs, and Tracing

Correct answer: A

Explanation

The correct answer is A: Metrics, Logs, and Traces, as these are the established three pillars that provide insights into system performance and behavior. Options B and D include terms that are not part of the core pillars, while option C replaces 'Logs' with 'Data', which is too broad and does not specifically reflect the observability framework.
