What's Actually Tested on AZ-305
Short summary
AZ-305 is a scenario-based exam testing architectural decision-making across four domains: infrastructure, identity/governance, data storage, and business continuity. Rather than memorizing Azure services, you must match constraints (cost, SLA, team skills, legacy dependencies) to the right solution tier. Worked examples show how tradeoffs—like choosing VMs over AKS for COM-dependent legacy apps—are justified by constraint analysis, not idealism.
