Certification Practice Vault

A focused, execution-first vault of real exam-style practice questions and scenarios for DevOps and Cloud certifications — starting with Kubernetes (CKA / CKAD) and expanding over time.

What This Project Is

This repository is a living practice vault I built while preparing for cloud and DevOps certifications.

Instead of treating certifications as a one-time achievement, I documented everything I actually did while preparing:

  • questions I struggled with
  • commands I ran
  • mistakes I made
  • terminal outputs
  • debugging paths
  • explanations that finally made things click

What you see here is not theory written after success — it is work captured during preparation.

Project Objective

This project serves three clear purposes:

  1. Proof of Work Each certification here is backed by real, hands-on execution — not just a badge or PDF.

  2. Reusable Practice Vault Over time, this repository becomes a growing vault of realistic practice material for future certifications (Terraform, AWS, KCNA, CKS, etc.).

  3. Public Learning Asset Anyone preparing for the same certifications can use this vault to understand how problems are solved, not just what the answers are.

How the Content Was Created

All questions and scenarios here come from real preparation work, primarily using:

  • Killercoda labs
  • KodeKloud labs and practice environments
  • Self-designed variations while experimenting
  • Failures and corrections discovered through hands-on work

When something failed, I documented why.

When something worked, I kept the exact terminal output.

This is deliberate.

How to Use This Vault

  • Pick a certification or domain
  • Read the question carefully
  • Follow the terminal output and steps
  • Notice why something failed or succeeded
  • Re-run the commands yourself

If you can execute what’s written without guessing, you are genuinely exam-ready.

Important Notes

  • This is not polished documentation
  • Explanations may include raw, AI-assisted troubleshooting
  • Language reflects real-time problem solving
  • Content favors execution over theory

All of this is intentional.

Project Status

This is an ongoing engineering project.

As I prepare for more certifications, new folders and practice material will be added following the same philosophy:

learn by doing, document while doing

If you’re looking for perfect notes, this is not that.

If you want to see how real preparation actually happens, you’re in the right place.
