Prepare for AZ-305 by practicing architecture reasoning: why one Azure design fits identity, data, continuity, infrastructure, monitoring, security, and cost requirements better than another.
Use Microsoft’s AZ-305 study guide as the source of truth for current scope. The guide lists the audience profile, skill areas, ranges, and detailed objectives. It also points to Azure Architecture Center and other Microsoft resources. Build preparation around Microsoft’s published skills rather than unsupported study-hour estimates.
Group study into design categories: identity and governance, monitoring, relational and non-relational data, backup and disaster recovery, high availability, compute, application architecture, migration, and networking. Within each category, write down the design choice you are making and the requirement that drives it.
Compare services that candidates realistically confuse. Use Azure SQL Database versus SQL Managed Instance for relational workloads, Cosmos DB versus relational databases for global or schema-flexible workloads, App Service versus Functions versus Container Apps versus AKS for compute, Front Door versus Application Gateway versus Load Balancer versus Traffic Manager for traffic management, and ExpressRoute versus VPN Gateway for hybrid connectivity.
Business continuity should be tied to RTO, RPO, workload type, data tier, and region strategy. Review Azure Backup, Site Recovery, zone redundancy, geo-redundant storage, SQL automated backups, failover groups, Cosmos DB multi-region options, and application-level recovery patterns. The best answer depends on the recovery objective and acceptable complexity.
After practice questions, explain why the wrong designs fail. One answer might solve resiliency but miss security, reduce cost but increase recovery time, or meet monitoring needs without addressing governance. AZ-305 readiness improves when you can connect each decision to the business and technical requirements in the scenario.
