DevOps Engineer Jobs — Best Certifications & How to Become One
Employers hiring DevOps engineers most often ask for CLF-C02, AZ-400 and CKA certifications. This page shows what the job involves, the certification path in the right order, and every certification we cover for it — each with a free practice test.
What Does a DevOps Engineer Do?
DevOps engineers automate how software gets built, tested and released: pipelines, infrastructure as code, containers and Kubernetes, plus the monitoring that keeps releases safe. It is a senior-leaning field built on top of cloud and system skills.
The path starts with a cloud foundation, then the Azure DevOps expert exam (AZ-400), with Kubernetes (CKA) as the skill almost every DevOps job post names.

DevOps Engineer Certification — FAQs
Which certification should I take first for devops engineer jobs?
Start with a cloud foundation — CLF-C02 (AWS) or AZ-900 (Azure). DevOps exams like AZ-400 assume you already know a cloud platform.
Do I need experience before I start?
AZ-400 expects real experience first — Microsoft designs it for people who have already worked in Azure administration or development.
How long does preparation take?
It depends on your starting point and how many hours a week you study. Fundamentals exams usually take a few weeks of steady study; associate and professional exams take longer because they test hands-on scenarios. Practising by domain — and reviewing every explanation — matters more than total hours.
Are the practice tests on Study4Pass free?
Yes. Every exam page on Study4Pass has a free practice test you can start without paying, so you can check your level before you commit to a study plan.
