Provides step-by-step solutions with expected output for all four exercises from the Core Concepts chapter, covering Pod creation, label management, selector filtering, and kubectl explain workflows.

Solutions: Core Concepts Exercises

This chapter contains detailed solutions for the four exercises presented at the end of the Core Concepts chapter. Each solution includes the exact commands to run, the expected output, and an explanation of what is happening at each step.

How to use these solutions:

  1. Attempt every exercise on your own first. Struggling through a task builds the muscle memory that timed exam conditions demand.
  2. If you get stuck, read only the next step — not the entire solution. Partial hints are more valuable than complete answers.
  3. After completing an exercise (with or without help), re-read the explanation to reinforce why the commands work, not just what they do.
  4. Repeat exercises that took more than a few minutes. The goal is fluency — executing these patterns without hesitation under the 2-hour exam clock.

The solutions are split into two sections: Pod creation and label management (Exercises 1–2), and selector filtering with kubectl explain (Exercises 3–4). Each section covers the commands, validates the results, and highlights common mistakes to watch for.
