Kubernetes and Cloud Native Security Associate (KCSA) Practice Test
Prepare for the Kubernetes and Cloud Native Security Associate exam with free practice tests built around the official KCSA curriculum. Each test has 20 questions with a proportional timer based on the commonly documented 90-minute, 60-question exam pace of 1.5 minutes per question.
Mixed Set — KCSA Practice Tests
Questions are distributed across all six KCSA domains according to the official CNCF exam weights. Higher-weighted areas like Kubernetes Cluster Component Security and Kubernetes Security Fundamentals appear more often across the mixed sets.
Domain Wise — KCSA Mock Tests
Target individual cloud native security domains with focused practice. Each mock test helps you review a specific part of the KCSA blueprint before moving back into full mixed-set practice.
About the KCSA Certification Exam
Everything you need to know about the Kubernetes and Cloud Native Security Associate exam format, objectives, eligibility, and career value.
What Is the KCSA?
The Kubernetes and Cloud Native Security Associate (KCSA) is an associate-level certification from CNCF and The Linux Foundation. It validates foundational knowledge of security technologies in the cloud native ecosystem, including Kubernetes security controls, cluster component security, platform security, threat modeling, compliance, and security frameworks.
KCSA is designed for learners who want to build toward Kubernetes security, cloud security, DevSecOps, platform engineering, SOC, and infrastructure security roles. It is especially useful for candidates who understand basic Kubernetes concepts and want a structured security-focused credential before progressing to more advanced certifications such as CKS.
Cloud native security skills align with a strong cybersecurity job market. The U.S. Bureau of Labor Statistics reports a median annual wage of $124,910 for information security analysts in May 2024 and projects 29% employment growth from 2024 to 2034. KCSA can support entry-level and early-career paths such as Cloud Security Associate, Kubernetes Security Analyst, DevSecOps Associate, Platform Security Engineer, and Security Operations Analyst.
Exam Format (2026)
Testing method: Online, proctored exam delivered through The Linux Foundation exam platform.
Questions: Commonly documented as 60 multiple-choice questions.
Duration: 90 minutes.
Question types: Multiple-choice and knowledge-based cloud native security scenarios.
Passing score: Commonly referenced as 75%.
Exam fee: $250 USD, with one free retake included.
Validity: Certification is valid for 2 years.
Eligibility Requirements
Prerequisites: There are no formal prerequisites for the KCSA exam.
Recommended background: Basic understanding of Kubernetes architecture, containers, Linux fundamentals, cloud native applications, and security concepts.
Experience level: Beginner to associate level. KCSA is positioned before deeper hands-on certifications such as CKS.
Exam eligibility window: Linux Foundation exam purchases include 12 months of exam eligibility.
Retake policy: One free retake is included with the exam purchase.
KCSA Domain Weights — Current Exam Curriculum
The KCSA exam covers six cloud native security domains. Domain weights below follow the current CNCF certification page and help guide how much study time to spend in each area.
| Domain | Topic | Weight |
|---|---|---|
| Domain 1 | Overview of Cloud Native Security | 14% |
| Domain 2 | Kubernetes Cluster Component Security | 22% |
| Domain 3 | Kubernetes Security Fundamentals | 22% |
| Domain 4 | Kubernetes Threat Model | 16% |
| Domain 5 | Platform Security | 16% |
| Domain 6 | Compliance and Security Frameworks | 10% |
How Our Practice Tests Are Designed
Blueprint-aligned coverage — Mixed sets follow the official KCSA domain weights, including 22% coverage each for Kubernetes Cluster Component Security and Kubernetes Security Fundamentals, 16% each for Kubernetes Threat Model and Platform Security, 14% for Overview of Cloud Native Security, and 10% for Compliance and Security Frameworks.
Cloud native security focus — Questions emphasize concepts candidates must understand for a knowledge-based KCSA exam: Kubernetes components, pod security, identity, authorization, network policy, threat modeling, supply chain controls, observability, compliance, and platform safeguards.
Proportional timer — The commonly documented KCSA format is 60 questions in 90 minutes, or about 1.5 minutes per question. Each 20-question practice test is timed at approximately 30 minutes to help you build real exam pacing.
Domain-specific review — Use domain-wise tests to strengthen weak areas before returning to mixed sets. This approach is useful when you consistently miss questions about cluster components, security fundamentals, platform controls, or compliance frameworks.
KCSA Exam Preparation Tips
Study Strategy
Start with Kubernetes basics: Review pods, deployments, services, namespaces, the API server, kubelet, etcd, admission control, and the Kubernetes control plane before diving into security objectives.
Map every topic to a security control: As you study, connect each concept to a defensive purpose, such as reducing privilege, limiting network access, protecting secrets, hardening images, or improving auditability.
Use the domain weights: Spend extra time on Kubernetes Cluster Component Security and Kubernetes Security Fundamentals because each carries 22% of the exam weight.
Test-Taking Strategy
Watch for security-first wording: KCSA questions often test the safest or most appropriate control, not just whether a technology exists.
Eliminate broad answers: Remove answers that are too vague, skip compliance requirements, or ignore Kubernetes-native security controls such as RBAC, NetworkPolicy, Pod Security Standards, and audit logging.
Manage the timer: With about 1.5 minutes per question, avoid spending too long on one scenario. Mark difficult concepts during practice and review them after the test.
