The Microsoft Azure Solutions Architect Expert certification — earned by passing the AZ-305 exam — is the most prestigious Azure credential available in 2026. It validates the ability to design cloud and hybrid solutions that run on Microsoft Azure, including compute, storage, network, security, identity, and governance architecture. For cloud professionals targeting senior architect roles and the $120,000–$160,000 salary range, AZ-305 is the definitive credential.
AZ-305 Prerequisites
Unlike other Azure certifications, AZ-305 has a formal prerequisite. Microsoft requires you to first hold one of:
- AZ-104 (Microsoft Azure Administrator)
- AZ-204 (Developing Solutions for Microsoft Azure)
- An equivalent Azure associate-level credential
This prerequisite matters because AZ-305 assumes operational Azure knowledge at the associate level. Candidates who attempt AZ-305 without first passing AZ-104 or equivalent certification consistently underperform — the exam builds on operational knowledge rather than repeating it.
AZ-305 Exam Domains in 2026
Design Identity, Governance, and Monitoring Solutions (25–30%) — Designing Azure AD architectures for complex multi-tenant and hybrid scenarios, governance designs using Management Groups, Azure Policy, and Azure Blueprints, and monitoring architectures using Azure Monitor and Log Analytics.
Design Data Storage Solutions (25–30%) — Selecting appropriate storage solutions for different data types and access patterns, designing relational and non-relational database architectures, designing data integration solutions, and designing data retention and archival strategies.
Design Business Continuity Solutions (10–15%) — Designing high availability architectures, backup solutions using Azure Backup and Azure Site Recovery, and disaster recovery strategies across regions.
Design Infrastructure Solutions (25–30%) — Designing compute architectures (VMs, containers, serverless, App Service), networking architectures (hybrid connectivity, VNet design, load balancing), and application architectures (microservices, API management, event-driven architectures).
How AZ-305 Differs From AZ-104
AZ-104 tests operational knowledge: how to configure and manage Azure resources. AZ-305 tests architectural thinking: how to design Azure solutions to meet specific business and technical requirements.
This distinction creates a specific preparation challenge. There are fewer definitively correct technical answers in AZ-305 — many questions present a scenario with multiple reasonable architectural approaches and ask you to select the one that best meets a described constraint (cost, performance, security, operational complexity, organizational requirements).
The architectural decision-making mindset that AZ-305 rewards comes from three things: deep familiarity with Azure service capabilities and limitations, understanding of architectural tradeoffs, and practice with the specific scenario-based question format the exam uses.
The Most Heavily Tested AZ-305 Topics
Storage account selection — Questions frequently present workloads with specific IOPS, throughput, redundancy, and access pattern requirements and ask you to select the appropriate storage solution. Knowing the limits of each storage type (Azure Blob, Azure Files, Azure Disk, Azure NetApp Files) and redundancy options (LRS, ZRS, GRS, GZRS) is essential.
Hybrid identity architecture — Designing Azure AD Connect implementations for different on-premises AD synchronization scenarios, including pass-through authentication vs. password hash sync vs. federation, is tested in multiple scenario formats.
Disaster recovery RTO/RPO — Questions present RTO (Recovery Time Objective) and RPO (Recovery Point Objective) requirements and ask you to select the architecture that meets them. Understanding which redundancy and replication options satisfy which RTO/RPO targets is directly tested.
Network topology design — Hub-spoke vs. mesh topology decisions, Azure Virtual WAN vs. traditional hub-spoke with NVA, ExpressRoute vs. VPN Gateway selection for hybrid connectivity — all are tested in architectural scenario questions.
Compute service selection — When to recommend VMs vs. Azure Kubernetes Service vs. Azure Container Apps vs. App Service vs. Azure Functions for a described application workload requires understanding the operational characteristics, pricing models, and scaling behaviors of each option.
For current AZ-305 practice questions that focus on architectural decision-making scenarios across all four domains, CertEmpire’s AZ-305 exam dumps provide comprehensive coverage with detailed explanations that address the tradeoff reasoning the exam rewards.
AZ-305 Study Plan: 10–14 Weeks (After AZ-104)
Weeks 1–3: Identity and governance — Advanced Azure AD scenarios, PIM for privileged access governance, Azure Policy at scale, Management Group hierarchy design.
