CKA Exam at a Glance

According to The Linux Foundation, “For the CKA Exam, a score of 66% or above must be earned to pass.”^[2]

CKA content outline and where to practise each area

The content areas below are copied from the official CKA content outline published by The Linux Foundation, with the share of the exam each area carries. The right-hand column shows which of our practice sets covers it.

Worked examples: how to reason through CKA questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: Which flag streams live log output continuously from a pod?

1. --stream
2. --follow
3. --live
4. --tail

Answer: B. --follow

Explanation:

The correct option is --follow (short form -f). It keeps the connection to the pod open and prints new log lines as the container writes them, much like tailing a file.

--stream and --live are not options of the log command, so kubectl would reject them. --tail is a real flag, but it controls how much existing output is shown, starting from the end of the log. On its own it prints that portion and exits, so it does not give you a live feed.

The rule to remember: one flag decides how much history you see, and a separate flag decides whether the output keeps streaming. You can combine them to show recent lines and then keep watching.

Example 2

Question: Which Kubernetes resource is used to securely store sensitive data like API keys and passwords?

1. ConfigMap
2. Secret
3. PersistentVolume
4. ServiceAccount

Answer: B. Secret

Explanation:

The correct option is Secret. It is the Kubernetes object meant for sensitive values such as passwords, tokens and keys, and Pods can receive it as files or environment variables.

A ConfigMap has the same shape but is intended for non-sensitive settings, so putting credentials there loses the access controls and handling that Secret objects get. A PersistentVolume is a piece of storage, not a place to keep configuration values. A ServiceAccount is an identity that Pods use when talking to the API, not a container for data.

The rule to remember: match the object to the job. Sensitive values go in a Secret, plain settings in a ConfigMap. Secret values are only encoded by default, so still limit who can read them.

Example 3

Question: What is a Pod in Kubernetes?

1. The smallest deployable unit that can contain one or more containers
2. A physical server
3. A network switch
4. A database table

Answer: A. The smallest deployable unit that can contain one or more containers

Explanation:

The correct option is the smallest deployable unit that can contain one or more containers. A Pod wraps its containers so they share networking and storage and are scheduled together onto a node.

A physical server is wrong because that describes a node, and even a node is usually a machine that hosts many Pods. A network switch is hardware that Kubernetes does not model as a Pod, although networking plugins connect Pods to each other. A database table is a data structure inside an application and has no link to how Kubernetes runs workloads.

The rule to remember: you rarely create bare Pods yourself. Controllers such as Deployments create and replace them, so think of a Pod as the unit that gets scheduled and restarted.

How to use these practice tests

Start with the official outline from the Linux Foundation and sort each domain into what you can already do without looking anything up and what you cannot. The exam is performance-based, so reading alone will not be enough; keep a practice cluster open while you study.

1. Take the Start Practice Test set once, cold, to see which areas are weakest.
2. Work the weakest domain first. For troubleshooting use CKA Troubleshooting, and for scheduling use CKA Workload Scheduling.
3. For every question you miss, reproduce the situation in your cluster and fix it from the command line, rather than only reading the explanation.
4. Cover supporting topics with CKA Cluster Maintenance, CKA Logging and Monitoring and CKA Security.
5. Practise speed. Time yourself on small tasks and learn to look up syntax in the official Kubernetes documentation quickly.
6. In the last days, retake the sets you missed most and re-read the exam rules from the Linux Foundation, including the environment and proctoring requirements.
