The CKA program was created by the Cloud Native Computing Foundation (CNCF), in collaboration with The Linux Foundation

CKA is not an easy exam, the exam has tasks instead of questions like other exams.

Questions provide details on what needs to be implemented, candidates are expected to configure it in the provided environment.

Candidates should have hands-on experience with Kubernetes.

This guide will help you prepare for CKA exam.

On June 25, 2022, The Linux Foundation migrated the CKA, CKAD and CKS programs from PSI’s ExamsLocal proctoring platform to PSI Bridge, as candidates were notified about beginning last year, and reminded of last month.

There were no changes to the exam content. The major changes are that candidates:

The introduction of the secure browser improves privacy (candidates no longer have to share their desktop), promotes equity (all candidates now take the exam using identical environments) and enhances the integrity of the exam by requiring the candidates to remain in the secure browser for the entirety of their session (instead of having access to local services, personal bookmarks, etc.).

Within the secure browser candidates will see a new user interface, with a Linux (XFCE) Remote Desktop within which they can access allowed documentation, open multiple terminals (without having to rely on tmux), change font sizes and colors, etc.

In the days following the migration, some candidates encountered issues which are outlined below.

Linux Foundation engineers and support team have resolved the issues flagged to date.

Linux Foundation continue to improve the exam user interface and resolve problems reported to our support team.

To report an issue or make a request please open a ticket at: https://trainingsupport.linuxfoundation.org.

Copy/Paste and Keyboard Shortcuts

The Terminal is a Linux Terminal, and candidates need to use Linux Terminal keyboard shortcuts:

Copy = CTRL+SHIFT+C

Paste = CTRL+SHIFT+V for Paste

OR Use the Right Click Context Menu and select Copy or Paste

YAML Formatting Issues when Copy/Paste from CNCF Documentation into VIM

This is a known VIM configuration behavior, and candidates need to :set paste before pasting the content into VIM.

Linux Foundations has implemented a VIM configuration change on 06/29 to mitigate this behavior.

Personal Bookmarks/ Chrome Browser Not Available

The Linux Remote Desktop includes a Firefox Browser; candidates are prohibited from accessing all sites except those listed in our Resources Allowed Policy.

Personal browser bookmarks (such as bookmarked links to YAML files) are not accessible within the PSI Secure Browser.

All Exam items have been updated with “Documentation Quick Links”, which provide links to the official Kubernetes documentation related to a handful of Kubernetes topics that might be required to solve a task.

The Kubernetes documentation pages have been carefully selected to fit the topics and typically provide one or more YAML files that might help kickstart working on a task.

PSI Check-in Process

Instead of relying on a proctor, Candidates now perform self check-in at Exam launch time (or up to 30 minutes prior to exam time). These steps are documented in our Candidate Handbook.

A PSI Check In Specialist will review and approve check-in assets (files uploaded by the candidate) and where necessary request that candidates resubmit photos or videos as needed.

New Exam UI

The remote desktop is configured with all the tools and software needed to complete the tasks. This includes:

Guidelines and Tips for using the Remote Desktop

The CKA certification is designed to ensure that certification holders have the skills, knowledge, and competency to perform the responsibilities of Kubernetes Administrators.

The CKA certification allows certified administrators to quickly establish their credibility and value in the job market, and also allowing companies to more quickly hire high-quality teams to support their growth.

As one of the highest velocity projects in the history of open source, Kubernetes use is exploding.


The Cloud Native Computing Foundation is committed to growing the community of Kubernetes application developers, thereby enabling continued growth across the broad set of organizations
using the technology.

Kubernetes adaption is growing very fast.

It provide power to administrator over how infrastructure resources are used.

CKA is one of the best devops certification with practical exam environment.

You can make above $100K annual salary,

CKA exam cost $375 with one free retake.

You can book exam at here

Check Kubernetes labs

You get free access to Killer.sh (CKA exam simulator)

You can also try tasks at Kubernetes.io

Candidates get 2 hrs to complete CKA exam.

CKA certification is valid for 3 years and successfully completing the exam.

candidates will be test on Kubernetes v1.23 and etcd v3.5

Candidates can take one Free retake within 12 months of purchase

Candidates have the option to repurchase the exam at any time from the course catalog

Only one exam order will be “active” for each purchased exam.

When the Active purchase has been used (the candidate has taken the exam and passed OR you has taken both the first and second attempt and achieved “no pass”) the Claim Your Next Order button will be enabled in the exam checklist.

When you click the Claim Your Next Order button, the current exam data will be stored as a history and the candidate a new Exam Preparation Checklist will be displayed in the candidate’s portal.

Candidates will get 15-20 performance based tasks.

CKA Exams is delivered online and Candidates must provide their own computer with current version of Chrome browser.

Make sure you have third party cookies turned on for the duration of the exam.

you don’t need to install a virtual machine, use a client machine, or anything beyond a Chrome or Chromium browser

Make sure you have third party cookies turned on for the duration of the exam.

Candidates should run the PSI Online System Security Check to verify that their machine meets the technical requirements for taking a proctored exam.

The online proctored exam is taken on PSI’s Proctoring Platform “Bridge”, using the PSI Secure Browser (a web browser created to guarantee a secure exam delivery over a virtual connection).

The PSI Secure Browser download/installation will being when you Select “Launch exam” from the PSI Dashboard.

Candidates must provide their own computer with:

Reliable internet access

Ensure others on the same internet connection are not performing activities that use excessive bandwidth (i.e. holding conference calls, streaming content, gaming, etc.)

A wired connection is often more stable and robust than a wireless connectionTurn off bandwidth-intensive services (e.g. file sync, dropbox, BitTorrent)

Microphone

Please check to make sure it is working before you start your exam session.

Webcam

Ensure the webcam is capable of being moved as the proctor may ask you to pan your surroundings to check for potential violations of exam policy.

Try holding up your ID while viewing your webcam feed to ensure your placement and resolution are sufficient for the person viewing your feed to read your ID.

If you will be testing from an employer-provide ISP or will use an employer provided machine, please ensure that streaming will be allowed using WebRTC.

Candidates are not allowed to have other applications or browser windows running except the one on which the Exam is being shown.

Candidates should run the compatibility check tool to verify that their hardware meets the minimum requirements.
