FAQ: Everything about our Linux Foundation Authorized Instructors
Do you have questions about our Kubernetes trainers' expertise and methods? Here are answers to the most frequently asked questions.
🎓 Trainer Expertise and Credibility
1. What distinguishes a Linux Foundation Authorized Instructor from a regular Kubernetes trainer?
Technical Validation: They hold CNCF certifications (CKA, CKAD, CKS).
Pedagogical Validation: They are certified by Linux Foundation to deliver official training courses (LFS458, LFD459, LFS460).
Skills Maintenance: Each instructor is evaluated continuously based on satisfaction scores and must maintain active certifications.
2. Are your Kubernetes trainers only teachers or active consultants?
3. How do you ensure the Kubernetes trainer will be suited to my team's level?
đź“š Training Content and Pedagogy
4. Can official Linux Foundation training content be customized?
Inter-company (public sessions): We strictly follow the official Linux Foundation curriculum to ensure all certification exam topics are covered.
In-company (dedicated to your team): Yes. While we follow the official framework, the instructor can accelerate on modules you've already mastered and delve deeper into those relevant to your Kubernetes projects.
5. What is the role of practice (Labs) in Kubernetes training?
6. Are course materials and Labs in French or English?
Oral delivery by our trainers is in French (or English upon request).
Visual materials (Slides) and lab guides are officially in English. This is essential because CNCF certification exams are in English. Our instructors translate and explain each concept orally.
🎯 Certification Preparation
7. How does the trainer prepare us for CNCF certification exams?
Exam simulation: Practice with time constraints like the real exam.
kubectl mastery: Speed and efficiency with CLI commands essential for performance-based exams.
Troubleshooting scenarios: Complex debugging exercises that mirror exam questions.
8. Can we address our Kubernetes business issues during the training?
9. How does the trainer handle level differences within a group?
Discreetly identify participants struggling to provide targeted help without slowing down the group.
Offer additional challenges (Advanced Labs) to faster participants to maintain their engagement.
Use group dynamics so that different profiles enrich each other on Kubernetes concepts.
10. Are trainers informed about the latest Kubernetes and CNCF news?
