- Skipping monitoring, SRE, and security sections because they feel “secondary”.
- Studying AZ-400 without good grounding in Azure admin or dev (AZ-104 / AZ-204).
Best Next Certification After AZ-400
Once you complete AZ-400, you can extend your profile in three ways (same track, cross-track, and leadership). Examples from top software engineering certification trends include cloud specialization, security, and leadership-oriented credentials.
- Same track (DevOps depth):
- Azure Administrator Associate (AZ-104) or Azure Developer Associate (AZ-204) if you haven’t done them yet.
- Cross-track (multi-cloud / domain breadth):
- AWS Certified Developer – Associate or Google Professional Cloud Developer to become multi-cloud.
- Leadership / architecture:
- Cloud architect or security-focused certifications (such as cloud architecture or security professional tracks) that emphasize design, governance, and strategy.
