Linux Foundation PCA 30-, 60-, and 90-day study plan with topic order, review loops, and final-week priorities.
This plan is a compact route for Prometheus Certified Associate (PCA). It assumes you are using TechExamLexicon for concept clarity and the exact IT Mastery page for practice routing.

| Day 2 | Metrics model | Understand time series, labels, samples, counters, gauges, histograms, and cardinality. |
| Day 3 | PromQL | Filter, aggregate, rate, join, and reason about ranges and instant vectors. |
| Day 4 | Scraping and service discovery | Configure targets, jobs, exporters, relabeling, and Kubernetes discovery. |
| Day 5 | Alerting | Build useful alert rules, thresholds, for durations, labels, routing, and silencing. |
