Command Line Speed Optimization
- Set up kubectl aliases immediately: alias k=kubectl, alias kgp='kubectl get pods', etc.
- Enable bash completion: source <(kubectl completion bash)
- Use kubectl short names: po (pods), svc (services), deploy (deployments), cm (configmaps)
- Practice imperative commands: kubectl run, kubectl create, kubectl expose - much faster than YAML
- Master --dry-run=client -o yaml to generate YAML templates quickly
- Use kubectl explain <resource> to quickly check field specifications without leaving terminal
Documentation Navigation
- The exam allows access to kubernetes.io/docs - learn to navigate it FAST
- Bookmark critical pages in the exam environment at the start
- Use browser search (Ctrl+F) to find examples quickly on documentation pages
- Know where to find: kubectl cheat sheet, pod specs, service types, networkpolicy examples
- Practice searching for solutions during practice exams - don't memorize everything
- The search function works well - use terms like 'sidecar', 'cronjob', 'ingress' to find examples
Time Management Strategy
- You have 120 minutes for 15-20 questions - roughly 6-8 minutes per question
- Skip difficult questions and flag them - come back with remaining time
- Read each question twice - understand what's being asked before starting
- Verify your work before moving on: kubectl get, kubectl describe to confirm
- Don't spend more than 10 minutes on any single question on first pass
- Reserve 15-20 minutes at the end to review flagged questions
- Questions have different point values - prioritize higher-value questions
Hands-On Practice Approach
- Set up a local cluster immediately - you MUST have hands-on practice to pass
- Practice typing kubectl commands, not just reading about them
- Break things intentionally and practice troubleshooting
- Time yourself on practice scenarios - speed is critical for this exam
- Delete and recreate resources multiple times until commands are muscle memory
- Practice without looking at documentation first, then verify with docs
- Use killer.sh at least 1 week before exam to identify weak areas
YAML and Declarative Configuration
- Understand YAML indentation - use spaces, never tabs
- Use kubectl create/run with --dry-run=client -o yaml to generate base templates
- Learn to quickly edit YAML with vi/vim or nano in the exam environment
- Know the basic structure: apiVersion, kind, metadata, spec
- Practice adding containers, volumes, env vars to existing YAML
- Copy-paste examples from documentation and modify rather than writing from scratch
- Validate YAML with kubectl apply --dry-run=client before actual creation
Common Pitfalls to Avoid
- Always work in the correct namespace - check the question requirements
- Use 'kubectl config set-context --current --namespace=<name>' to switch contexts
- Verify resource creation with kubectl get before moving to next question
- Don't overcomplicate - exam questions test practical skills, not edge cases
- Watch for typos in labels and selectors - common source of errors
- Remember to save changes when editing with vi/vim (:wq)
- Read error messages carefully - they usually tell you exactly what's wrong
Exam Environment Familiarity
- The exam uses a Linux terminal with kubectl pre-installed
- You'll have access to multiple Kubernetes clusters - verify which one to use
- Practice switching contexts: kubectl config use-context <context-name>
- Test your environment setup before exam day using Linux Foundation checklist
- Ensure stable internet connection - exam is proctored via webcam
- Clear your desk completely - only water bottle allowed
- Have government-issued ID ready for identity verification
Exam Day Tips
- 1Start exam with 5 minutes setup: create kubectl alias, enable completion, test context switching
- 2Read ALL questions first and identify easy wins - tackle those first for confidence
- 3Use imperative commands wherever possible - much faster than writing YAML from scratch
- 4Always verify your work with kubectl get/describe before moving to next question
- 5Flag difficult questions immediately and move on - don't waste time being stuck
- 6Keep track of which context/namespace each question requires - easy points lost to mistakes
- 7Use kubectl explain when unsure about resource specifications
- 8Don't panic if you encounter unfamiliar scenarios - use documentation to find similar examples
- 9Watch the clock but don't obsess - aim to complete first pass with 30 minutes remaining
- 10Copy-paste commands and YAML from documentation when possible to avoid typos
- 11Test your solution works before moving on - a working partial answer is better than perfect non-working code
- 12Remember: 66% passing score means you can miss several questions and still pass
- 13Stay calm and methodical - this is a practical exam testing real-world skills you've practiced
