Study tips
Exam Environment Mastery
- The exam is performance-based in a real Linux terminal - no multiple choice questions
- You can access kubernetes.io documentation during the exam - practice navigating it quickly
- Bookmark important documentation pages beforehand and practice using browser search (Ctrl+F)
- Use kubectl imperative commands with --dry-run=client -o yaml to generate manifests quickly
- Set up kubectl aliases and bash completion in your practice environment (alias k=kubectl)
- Practice typing speed and accuracy - you'll be creating many YAML files
Time Management Strategies
- You have 2 hours for 15-20 questions - approximately 6-8 minutes per question
- Questions have different point values - tackle high-value questions first
- Use kubectl explain command to quickly check resource specifications
- Flag difficult questions and return to them - don't waste time on blockers
- Leave 15-20 minutes at the end to review flagged questions
- Practice completing tasks in under 5 minutes consistently
Hands-On Practice Focus
- Practice on actual Linux terminals, not just reading - this is a hands-on exam
- Break your lab cluster intentionally to practice troubleshooting
- Memorize common kubectl commands and YAML structures
- Practice etcd backup and restore until you can do it from memory
- Focus on imperative commands: kubectl create, expose, run, set
- Build muscle memory for vi/vim editor commands (you'll edit many YAML files)
Critical Commands to Master
- kubectl get pods -o wide --all-namespaces (check cluster state)
- kubectl describe [resource] [name] (detailed information)
- kubectl logs [pod] --previous (check crashed container logs)
- kubectl exec -it [pod] -- /bin/sh (debug running containers)
- journalctl -u kubelet (troubleshoot node issues)
- ETCDCTL_API=3 etcdctl snapshot save/restore (backup/restore)
- kubectl create deployment [name] --image=[image] --dry-run=client -o yaml
Documentation Navigation
- Practice finding answers in kubernetes.io documentation within 30 seconds
- Use documentation search with specific keywords (e.g., 'PersistentVolume example')
- Know where to find task-based guides: kubernetes.io/docs/tasks/
- Memorize locations of key pages: RBAC, NetworkPolicy, Storage
- Copy-paste YAML examples from docs and modify them - don't write from scratch
- Use kubectl explain for quick field reference without leaving terminal
Common Pitfalls to Avoid
- Always specify the correct namespace with -n flag or check current context
- Verify your changes with kubectl get and kubectl describe before moving on
- Double-check YAML indentation - use spaces, not tabs
- Read questions carefully - some ask for specific names, namespaces, or labels
- Don't forget to save files after editing in vi/vim (:wq)
- Test service connectivity from within a pod, not just from the node
- Remember that some tasks require working on specific nodes via SSH
Exam Day Preparation
- Test your webcam, microphone, and internet connection 24 hours before
- Clear your desk completely - only water bottle allowed
- Have government-issued ID ready for verification
- Close all applications except the exam browser
- Use a quiet room with good lighting for the proctored exam
- Read the question requirements carefully - some have multiple steps
- Take advantage of both Killer.sh sessions before the actual exam
Efficiency Techniques
- Set up kubectl aliases immediately: alias k=kubectl
- Enable bash completion: source <(kubectl completion bash)
- Use kubectl shortnames: po (pods), svc (services), deploy (deployments)
- Use --force flag with kubectl delete to skip graceful deletion when practicing
- Practice copy-paste techniques in your terminal emulator
- Use tab completion extensively for resource names and commands
- Keep a scratch pad file open for quick notes or YAML generation
Exam day checklist
- Start the exam with a clear head - take deep breaths if nervous
- Read each question completely before starting - note the namespace and context
- Switch context immediately if the question specifies a different cluster
- Verify your answer works before moving to the next question (test pods are running, services are accessible)
- Use kubectl get events to troubleshoot if something isn't working
- Don't panic if you can't solve a question - flag it and move on
- Remember that partial credit is given - attempt every question
- Keep track of time but don't obsess - stay focused on solving problems
- Document your approach with comments if creating complex YAML
- In the last 10 minutes, verify your high-value questions are complete
- Trust your preparation - you've practiced these scenarios many times
- If you fail, you get one free retake - learn from the experience
