A current guide to CKAD, including the 2-hour online performance format, Kubernetes v1.35 context, developer domain weights, simulator access, and hands-on application deployment priorities.
CKAD validates practical Kubernetes application development. Preparation should focus on building and modifying workloads, configuring application environments, deploying applications, observing health, debugging failures, and exposing services safely.
Use these points before scheduling the Linux Foundation CKAD exam or starting developer-focused Kubernetes practice.
CKAD is an online, proctored, performance-based exam made up of command-line Kubernetes tasks.
Linux Foundation lists the CKAD exam duration as 2 hours.
Linux Foundation lists the current CKAD product page as based on Kubernetes v1.35, with rolling alignment to recent minor versions.
Application Environment, Configuration and Security is the largest CKAD domain at 25%.
Linux Foundation lists one retake and two exam simulator attempts with the CKAD purchase.
Linux Foundation lists the CKAD certification as valid for 2 years.
CKAD is about creating and maintaining applications on Kubernetes. Spend most practice time on manifests, workloads, configuration, services, health checks, rollouts, and debugging rather than cluster installation.
Application Environment, Configuration and Security is 25% of the current curriculum. Practice ConfigMaps, Secrets, requests and limits, quotas, ServiceAccounts, SecurityContext, capabilities, admission concepts, CRDs, and operators.
The deployment and design domains together account for 40%. Practice choosing workload resources, using multi-container patterns, handling init containers, managing volumes, performing rollouts, deploying Helm packages, and using Kustomize.
Services and Networking plus Observability and Maintenance make up 35%. Practice Services, Ingress rules, NetworkPolicies, logs, probes, events, built-in CLI monitoring, and common application debugging flows.
Use this Certified Kubernetes Application Developer (CKAD) exam help page for exam-specific context, then compare the broader online exam help services page or contact HiraEdu if you need a direct handoff. This page stays focused on Certified Kubernetes Application Developer (CKAD) while the linked service pages cover broader exam support options.
Certified Kubernetes Application Developer is a vendor-neutral certification created by the Linux Foundation and CNCF for professionals who design, build, configure, and expose cloud-native applications on Kubernetes. The CKAD exam is an online, proctored, performance-based test made up of command-line tasks and Linux Foundation lists a 2-hour duration, 12 months of exam eligibility, one retake, two exam simulator attempts, a PDF certificate and digital badge, Kubernetes v1.35 at the time of the current product page, and certification validity of 2 years. The current curriculum weights are Application Design and Build 20%, Application Deployment 20%, Application Observability and Maintenance 15%, Application Environment, Configuration and Security 25%, and Services and Networking 20%. Candidates should be comfortable with OCI-compliant container images, cloud-native application concepts, Kubernetes manifests, Pods, Deployments, Services, ConfigMaps, Secrets, probes, logs, debugging, Helm, Kustomize, NetworkPolicies, and Ingress rules.
Linux Foundation lists the Certified Kubernetes Application Developer exam duration as 2 hours.
No. CKAD is an online, proctored, performance-based exam made up of command-line Kubernetes tasks.
The current weights are Application Design and Build 20%, Application Deployment 20%, Application Observability and Maintenance 15%, Application Environment, Configuration and Security 25%, and Services and Networking 20%.
Linux Foundation lists no formal prerequisite for the CKAD exam, but candidates should know container runtimes, microservice architecture, and Kubernetes resource definitions.
Practice building and editing Kubernetes manifests, deploying workloads, configuring applications, debugging Pods, exposing Services and Ingress, using NetworkPolicies, and working quickly in the command line.
Check Linux Foundation candidate instructions for the current Kubernetes minor version before your exam date.
Build study time around 20%, 20%, 15%, 25%, and 20% domain weights.
Practice fast kubectl creation, YAML edits, labels, selectors, environment variables, ConfigMaps, Secrets, probes, volumes, and resource requirements.
Work through Services, Ingress, NetworkPolicies, logs, events, broken Pods, image issues, readiness failures, and rollout problems.
Run the included simulator attempts after you have enough speed to make the scoring feedback useful.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
