Domain 3: Workloads & Scheduling

Certified Kubernetes Administrator (CKA) · this domain is approximately 15.0% of the exam · 0 practice questions.

Workloads and Scheduling covers how applications are defined, deployed, and placed onto cluster nodes in Kubernetes. The CKA exam tests the full set of workload resources including Deployments, StatefulSets, DaemonSets, Jobs, and CronJobs, and how each manages pod lifecycle, scaling, and rollout strategy. Scheduling topics include node selectors, node affinity and anti-affinity rules, taints and tolerations, resource requests and limits, and priority classes that influence the scheduler's decisions. Candidates are expected to diagnose scheduling failures, configure horizontal pod autoscaling, and understand how resource quotas and limit ranges affect workload placement across namespaces.
