I passed the CKA (Certified Kubernetes Admin) exam. My score wasn't great, but I'll chalk it down to the bad night's sleep that I had.
Overall:
* I enjoyed the exam, it's well made, user-friendly and a fun challenge.
* The test-at-home solution from PSI works well and my proctor was polite and patient.
* I trained via KodeKloud and Killer.sh. The prior offers excellent value for money, the latter gave two free test exams via the Linux Foundation voucher.
