Frequently asked questions

Are all of these certifications official?

Yes. Every entry links to the official provider page (AWS, Microsoft, Google, the Linux Foundation/CNCF, HashiCorp, Red Hat and others). DevOpsSchool.org does not list or sell unofficial certificates.

Which certification should I take first?

For cloud-native roles, KCNA or a cloud foundational cert (AWS Cloud Practitioner, AZ-900) is the gentlest entry. For hands-on Kubernetes credibility, CKA remains the highest-signal associate-level exam.

Do certifications expire?

Most expire after 2–3 years and require renewal or re-examination. Each registry entry shows the official renewal period.
