Azure AZ-104 vs AZ-305: Which Azure Cert Should You Get First?
Azure Administrator vs Solutions Architect Expert — know the difference before you decide.
The Natural Progression
This isn't really an "either/or" — AZ-104 is a prerequisite for AZ-305. You must pass AZ-104 first to earn the Azure Solutions Architect Expert certification. But understanding what each tests helps you plan your study path.
AZ-104: Hands-On Administration
AZ-104 tests your ability to manage Azure resources day-to-day:
- Manage Azure identities and governance
- Implement and manage storage
- Deploy and manage compute
- Configure virtual networking
- Monitor and maintain resources
It's practical and operational. Expect questions about Azure CLI commands, PowerShell, ARM templates, and portal configurations.
AZ-305: Strategic Architecture
AZ-305 tests your ability to design Azure solutions:
- Design identity, governance, and monitoring solutions
- Design data storage solutions
- Design business continuity solutions
- Design infrastructure solutions
It's about making architectural decisions — choosing between services, designing for scale, cost-optimizing, and meeting compliance requirements.
Study Strategy
Since you need both, here's the optimal approach:
- Pass AZ-104 first — build hands-on Azure skills (8-12 weeks)
- Gain real-world experience — work with Azure for 3-6 months
- Pass AZ-305 — leverage your admin knowledge for architecture decisions (6-8 weeks)
Fast Track
If you already have 2+ years of Azure experience, you can compress this to AZ-104 (4 weeks) → AZ-305 (4 weeks). Your hands-on experience fills the gaps.
