First, start with Microsoft Certified Azure Fundamentals certification. Even though it is optional, I would suggest completing this certification before you start for associate-level certifications. Then, go for associate-level certifications such as Microsoft Certified Azure Administrator and Microsoft Certified Azure Developer. You can check out these Azure Training and Azure Developer Associate courses by Intellipaat to prepare for these associate-level certifications.
After that, go for the expert level certifications such as Microsoft Certified Azure Solutions Architect and Microsoft Certified Azure DevOps Engineer.
