Prepare for the CKA - Certified Kubernetes Administrator exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
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.
Question: Which flag streams live log output continuously from a pod?
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.
Question: Which Kubernetes resource is used to securely store sensitive data like API keys and passwords?
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.
Question: What is a Pod in Kubernetes?
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.
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.
The CKA (Certified Kubernetes Administrator) test checks your skills in managing Kubernetes. It’s a key test for those working with Kubernetes, the open-source container platform. Knowing the test’s parts, how it’s structured, and what it covers is key to passing.

The CKA certification is a performance-based exam administered by the Cloud Native Computing Foundation (CNCF) and the Linux Foundation, validating skills required to work as a Kubernetes administrator. Candidates have 2 hours to complete hands-on tasks in a live terminal environment, and a passing score of 66% is required against the current Kubernetes v1.31 curriculum.
The exam covers Storage (10%), Troubleshooting (30%), Workloads and Scheduling (15%), Cluster Architecture, Installation and Configuration (25%), and Services and Networking (20%). The certification is valid for two years and costs $395, which includes one free retake if you fail your first attempt.
To pass the Certified Kubernetes Administrator (CKA) test, you need a solid plan. This plan should include hands-on practice, mock exams, and studying all the materials you can get. With the right mix of resources, you can master the skills needed for the CKA certification.
Hands-on lab exercises are a top way to get ready for the CKA test. They let you practice what you’ve learned in real-life situations. This way, you can really understand how to manage Kubernetes clusters, handle networking, and keep things secure.
It’s key to practice in environments that feel like the real test. There are many platforms out there that mimic the CKA exam. They help you see how you’ll do and where you need to improve. This practice boosts your confidence and makes sure you’re ready for the test.
Having the right study materials and Kubernetes documentation is vital. Look for a variety of educational resources like online courses and study guides. By diving into Kubernetes content, you’ll get a deeper grasp of its key parts, networking, security, and cluster management.
Try these questions from our free Certified Kubernetes Administrator practice tests. The correct answer and an explanation follow each question.
Which Ingress `pathType` value matches only the exact URL path with no prefix tolerance?
Answer: B. Exact
The `Exact` pathType matches only requests whose URL path is identical to the specified path, with no trailing slash tolerance.
A ConfigMap is mounted as a volume in a Pod. After the ConfigMap is updated, what happens to the files inside the running Pod?
Answer: A. The files are eventually updated automatically by the kubelet
When a ConfigMap is mounted as a volume, the kubelet periodically syncs the projected files, so changes propagate eventually without a Pod restart.
A node has a pod with no replication controller. What happens when you run kubectl drain on that node?
Answer: B. The drain fails unless --force flag is used
kubectl drain refuses to delete pods not managed by a ReplicaSet, Deployment, or Job unless --force is specified, as they cannot be rescheduled.
Which Service type provisions an external load balancer from the cloud provider?
Answer: C. LoadBalancer
A Service of type LoadBalancer triggers the cloud controller manager to allocate an external LB with a public IP.
