• 4.3 Understand persistent volume claims
• 4.4 Know how to configure applications with persistent storage

Key concepts: PersistentVolume (PV) and PersistentVolumeClaim (PVC), StorageClass and Dynamic Provisioning, Access Modes (RWO, ROX, RWX), Reclaim Policies (Retain, Delete, Recycle), Volume Types (hostPath, emptyDir, NFS, CSI), CSI (Container Storage Interface) Drivers, Volume Snapshots, Ephemeral Volumes

Domain 5: Troubleshooting (30%)

• 5.1 Evaluate cluster and node logging
• 5.2 Understand how to monitor applications
• 5.3 Manage container stdout and stderr logs
• 5.4 Troubleshoot application failures

Recommended Study Timeline

Plan for approximately 6-10 weeks of dedicated study. Here is a suggested weekly breakdown:

• Week 1: Domain 1: Cluster Architecture — Control plane components (API server, etcd, scheduler, controller manager)
• Week 2: Domain 1: Installation — kubeadm cluster setup, RBAC configuration, managing cluster certificates
• Week 3: Domain 2: Workloads — Deployments, ReplicaSets, DaemonSets, StatefulSets, Jobs, CronJobs
• Week 4: Domain 2: Scheduling — Node selectors, affinity/anti-affinity, taints/tolerations, resource limits
• Week 5: Domain 3: Services — ClusterIP, NodePort, LoadBalancer, ExternalName, Ingress controllers
• Week 6: Domain 3: Networking — Network policies, DNS (CoreDNS), CNI plugins, pod-to-pod communication
• Week 7: Domain 4: Storage — PersistentVolumes, PersistentVolumeClaims, StorageClasses, volume types
• Week 8: Domain 5: Troubleshooting — Pod debugging, node issues, networking problems, log analysis
• Week 9: Domain 5: Advanced Troubleshooting — Control plane failures, etcd backup/restore, certificate issues
• Week 10: Full Review: Practice labs (killer.sh), kubectl drills, Weak areas, Exam logistics

Top Study Tips

1. Start with the official exam objectives. Download them from the Kubernetes website and use them as your study checklist. Every exam question maps to a specific objective.

1. Use active recall over passive reading. Instead of re-reading notes, test yourself with practice questions after each study session. This dramatically improves retention.

1. Focus on heavily-weighted domains first. Domains with higher percentages appear more on the exam. Master these before moving to lower-weighted areas.

1. Build hands-on experience. Set up a lab environment and practice the skills you are studying. Hands-on experience is especially valuable for performance-based questions.

1. Take practice exams under real conditions. Time yourself, eliminate distractions, and simulate the exam environment. Review every wrong answer and understand why it was wrong.
