AZ-305 Exam Domains & Topics
Understand the domains and stop losing points on scenario tradeoffs.
Quick answers
- Secure: IAM + encryption + least privilege.
- Resilient: HA/DR basics, fault tolerance.
- High-performing: caching, scaling, right service choice.
- Cost-optimized: storage tiers and pricing tradeoffs.
AZ-305 is architecture-heavy: you’re tested on making the right design choice for a scenario with constraints.
Domains repeat the same core decisions: identity/governance controls, network topology, storage selection, and resiliency patterns.
Use domain-based practice to avoid random studying and to cover gaps quickly.

How domains map to real questions
The exam is scenario-driven. Your score often depends on choosing the best architecture under constraints (cost vs performance vs reliability vs security).
- Design secure architectures: IAM, encryption, least privilege.
- Design resilient architectures: HA, DR, fault tolerance.
- Design high-performing architectures: caching, scaling, right service choice.
- Design cost-optimized architectures: storage classes, pricing tradeoffs.
Topics & Skills Covered
- Identity, governance, monitoring
- Data storage architecture
- Business continuity and DR
- Infrastructure architecture

Frequently Asked Questions
What type of questions appear in AZ-305?
Mostly scenario-based: you choose the best architecture option given requirements (security, cost, availability, operations).
How do I avoid getting tricked?
Underline constraints (RTO/RPO, compliance, connectivity, scale). Then pick the simplest design that meets them.
Should I study services or patterns?
Both, but patterns win: hub-spoke, landing zones, DR strategy, identity boundaries, monitoring design.
