My CKA Certification Experience and Rapid‑Study Guide

On the night of January 22, 2024, the author took the Certified Kubernetes Administrator (CKA) exam and passed with a score of 95 out of 100. This article presents their exam experience and a fast‑track study guide.

CKA Certification

The official description states that the CKA certification ensures Kubernetes administrators possess the necessary skills, knowledge, and abilities for professional practice.

Certified administrators are capable of installing, configuring, and managing production‑grade Kubernetes clusters, understanding networking, storage, security, maintenance, logging, monitoring, application lifecycle, troubleshooting, API objects, and can build basic use cases for end users.

CKA Exam Outline

The official exam outline (shown in the image below) may look intimidating, but the actual questions are straightforward.

Preparation and Strategy

If you already work with Kubernetes or understand its core resources, that background is sufficient; even complete beginners can pass by practicing the exam questions and memorizing key concepts because the exam is relatively simple.

During the exam, log in half an hour early. The exam launches a standalone application called PSI (not a browser). PSI checks your computer and requires camera access, a single monitor, and other permissions. The author’s attempt to use an external monitor failed because the system detected two displays; therefore, a laptop with a screen larger than 15 inches is recommended for a comfortable experience.

To succeed quickly, focus on two actions:
