Kubernetes and Cloud Native Security Associate (KCSA) Practice Exams

The Kubernetes and Cloud Native Security Associate (KCSA) is an entry-level certification from the Cloud Native Computing Foundation (CNCF) and Linux Foundation that validates foundational understanding of Kubernetes and cloud-native security. It is designed for people who want to demonstrate a baseline awareness of the threat model, controls, and frameworks that protect Kubernetes clusters and the workloads running on them. The KCSA sits alongside the KCNA in the associate tier and acts as a stepping stone toward the hands-on Certified Kubernetes Security Specialist (CKS).

The exam consists of around 60 multiple-choice questions completed in 90 minutes. Topics include the four C's of cloud-native security (Cloud, Cluster, Container, Code), Kubernetes cluster component security across the API server, kubelet, etcd, and container runtime, pod security standards and admission controllers, the Kubernetes threat model and trust boundaries, supply-chain security, image scanning, observability, service meshes, PKI, and the major compliance frameworks. Unlike the CKS, the KCSA is knowledge-based and does not require live cluster work, so you can prepare effectively by reading the docs, working through scenario questions, and learning each control's purpose and limits.

Who should take the KCSA? It's a strong fit for platform engineers, DevOps engineers, SREs, security analysts, and developers who deploy to Kubernetes and want to validate that they understand the controls available to protect a cluster. It also works well as a security-focused complement to the KCNA for anyone planning to pursue the CKS later. Employers increasingly look for evidence that a candidate can reason about least privilege, secrets handling, network policies, and supply-chain risk before they ever touch production, and the KCSA is a direct way to demonstrate that.

Why is mock practice important for the KCSA? Many candidates underestimate the breadth of topics on the exam. Questions can pull from any of the six official domains and often require you to distinguish between similar controls (for example, NetworkPolicy versus Pod Security Standards, or RBAC versus admission controllers). Practising under exam conditions builds the recall speed and pattern recognition needed to clear the 75% passing bar, and it surfaces weak areas while there's still time to fix them.

Our KCSA practice sets are aligned to the latest exam curriculum and weighted to match the official domain split. Each question includes a detailed explanation covering why the correct answer is right and why each distractor is wrong, so you build real understanding rather than just memorising answers. Your scores are tracked across attempts so you can target your revision, and the first set is completely free to try before you buy.
