PCA (Prometheus Certified Associate) sample exam question with answer 249

Question:
What is the recommended application for visualization of Prometheus metrics in dashboards?

1. Prometheus UI Graph Tab
2. Kubernetes Dashboard
3. CNCF Landscape Dashboard
4. Grafana

Answer:
D - correct one
A - is incorrect. While the Graph tab provides basic querying and graphing capabilities, Grafana is the recommend application for visualization as it allows a huge amount of customization as well as the ability to build and save visualizations as dashboards
B - is incorrect as the Kubernetes dashboard is used to visualize the current status of Kubernetes cluster objects such as deployments, pods, etc. However, it is limited in flexibility even within the context of Kubernetes and cannot be used for visualization of arbitrary Prometheus metrics
C - is incorrect as the CNCF Landscape Dashboard is used for viewing available cloud native applications, not visualizing Prometheus metrics
