CERTIFICATION BUNDLE

認定Kubernetes管理者 (CKA-JP) + 認定Kubernetesセキュリティスペシャリスト (CKS-JP) 試験バンドル

PLEASE NOTE: The changes to the Certified Kubernetes Administrator (CKA) exam will be released on Tuesday, February 18, 2025 00:00 UTC. Any exams taken on or after that date will reflect the changes previously communicated.

Coming Soon: The current CKS Competency “Implement Pod-to-Pod encryption using Cilium” will be updated to “Implement Pod-to-Pod encryption (Cilium, Istio)” on April 8, 2025, at 00:00 UTC.

Who Is It For
The CKA certification is for Kubernetes administrators, cloud administrators and other IT professionals who manage Kubernetes instances. A Certified Kubernetes Security Specialist (CKS) is an accomplished Kubernetes practitioner (must be CKA certified) who has demonstrated competence on a broad range of best practices for securing container-based applications and Kubernetes platforms during build, deployment and runtime.

About These Certifications
CKA was created by The Linux Foundation and the Cloud Native Computing Foundation (CNCF) as a part of their ongoing effort to help develop the Kubernetes ecosystem. The exam is an online, proctored, performance-based test that requires solving multiple tasks from a command line running Kubernetes. CKS is a performance-based certification exam that tests candidates' knowledge of Kubernetes and cloud security in a simulated, real world environment. Candidates must have taken and passed the Certified Kubernetes Administrator (CKA) exam prior to attempting the CKS exam. CKS-JP may be purchased but not scheduled until a CKA certification has been achieved.

What It Demonstrates
A certified K8s administrator has demonstrated the ability to do basic installation as well as configuring and managing production-grade Kubernetes clusters. They will have an understanding of key concepts such as Kubernetes networking, storage, security, maintenance, logging and monitoring, application lifecycle, troubleshooting, API object primitives and the ability to establish basic use-cases for end users. Obtaining a CKS-JP demonstrates a candidate possesses the requisite abilities to secure container-based applications and Kubernetes platforms during build, deployment and runtime, and is qualified to perform these tasks in a professional setting.

The Linux Foundation worked with industry experts and the Linux kernel community to identify the core domains and the critical skills, knowledge and competencies applicable to each certification. Performance-based exams were then developed based on the competencies that were identified.
Exam Details & Resources
Both the CKA and CKS exams are online, proctored, performance-based tests that requires solving multiple tasks from a command line running Kubernetes. For each exam, candidates have 2 hours to complete the tasks.

The CKA exam is based on Kubernetes v1.32
The CKS exam is based on Kubernetes v1.32

The CKS and CKA exam environments will be aligned with the most recent K8s minor version within approximately 4 to 8 weeks of the K8s release date

Certified Kubernetes Security Specialist (CKS) candidates must have taken and passed the Certified Kubernetes Administrator (CKA) exam prior to attempting the CKS exam.

CKS may be purchased but not scheduled until CKA-JP certification has been achieved.
CKA Certification must be active (non-expired) on the date the CKS-JP exam (including Retakes) is scheduled.

Please review the Candidate Handbook, Curriculum Overview and Exam Tips along with other recommended resources below.

Prerequisites
