You need an active CKA to even sit it. Which is exactly why it carries weight on a CV. It signals you can secure a cluster end to end: hardening, supply-chain integrity, runtime detection, not just administer one. ## Prep tips - Get your CKA active first; the Linux Foundation checks this at scheduling time, so leave a buffer if yours is close to expiring. - Spend real practice time on tools the exam actually uses hands-on, such as Falco for runtime detection, network policies, and admission controllers, rather than just reading security theory. - Supply-chain security (image scanning, signing, sane base images) is a newer domain relative to the older CKA/CKAD content; don't skip it assuming it's a small footnote. ## How to use the code - Add the CKS exam to your cart on [training.linuxfoundation.org](https://www.awin1.com/cread.php?awinmid=85919&awinaffid=2950265&ued=https%3A%2F%2Ftraining.linuxfoundation.org%2Fcertification%2Fcertified-kubernetes-security-specialist%2F). - Enter `RUSHABH30` in the coupon field at checkout. - The total drops 30%. RUSHABH30 works on the exam alone, the exam bundled with the official prep course, and a retake within your eligibility window.

This is the one Linux Foundation Kubernetes cert with a hard prerequisite. You must hold an active CKA to schedule the CKS. **How much is the CKS with a discount code?** List price is $445. With RUSHABH30 it drops to about $311. **Is the CKS worth it if I already have the CKA?** For anyone doing platform or security work, yes. It's one of the strongest security-specific signals you can add to a DevOps CV, and it's a natural next step once your CKA is active. **Is the CKS multiple-choice?** No. Like the CKA and CKAD, it's 100% performance-based against live clusters. **Does RUSHABH30 work on the CKS course + exam bundle?** Yes, on the exam alone or bundled with the official prep course. ## Other Linux Foundation & CNCF certifications RUSHABH30 works on every Linux Foundation and CNCF course and certification, not just CKS.
