The main trade-off

Same Kubernetes family. Admin vs developer. Pick by which side of the cluster you operate.

The Linux FoundationAvailable

Certified Kubernetes Administrator (CKA)

CKA

Practical Kubernetes administration assessment. Prepare by operating a cluster, not just watching demonstrations.

Skip or defer if: You haven't deployed anything to k8s in production-like conditions

Experience: Linux fluency; Docker fluency
Exam cost: Indicative exam cost: £330

Exam details and sources

Live and performance based. The Linux Foundation states the exam environment is currently running Kubernetes v1.35, so the syllabus moves with the release.

Renewal: Two years. Certifications earned before 1 April 2024 run for three years.
Study planning: 2–4 months — editorial estimate, dependent on experience and weekly hours.
