This upgrade drops the CKA and sells the other four exams, so the only question worth asking is whether four exams at this price beats four separate purchases. It does, and by more than the single-exam discount does. ## Prep tips - CKS requires an active CKA, so confirm yours has not lapsed before buying. If it has, this is the wrong bundle and the full Kubestronaut one is the cheaper route. - KCNA and KCSA are both multiple choice and the quickest of the four. Take them first while you decide how much CKS preparation you actually need. - CKAD overlaps with the CKA more than people expect, so sitting it soon after the CKA while the kubectl muscle memory is fresh usually costs the least preparation time. ## How to use the code - Add the CKA to Kubestronaut bundle 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%2Fcka-to-kubestronaut-upgrade-bundle%2F). - Enter `RUSHABH30` in the coupon field at checkout. - The total drops 30%.

It is the Kubestronaut set minus the CKA, for people who already hold the CKA. **How much is the CKA to Kubestronaut upgrade with a discount code?** List price is $1235. With RUSHABH30 it drops to about $864, a saving of roughly $371. **Do I need an active CKA to buy this?** Yes, in practice. The bundle assumes you already hold the CKA, and CKS cannot be sat without an active one. If your CKA has expired, price up the full Kubestronaut bundle instead. **Is this cheaper than buying the four exams separately?** Yes. KCNA and KCSA at $250 each plus CKAD and CKS at $445 each comes to $1390 at list price, against $1235 for the bundle, before any code is applied. ## Other Linux Foundation & CNCF certifications RUSHABH30 works on every Linux Foundation and CNCF course and certification, not just CKA to Kubestronaut.
