AZ-305: Azure Solutions Architect Expert Exam Guide

What is this page about?

An exam guide to the Microsoft AZ-305 (Azure Solutions Architect Expert), the expert credential that requires an active AZ-104 as a formal prerequisite and typically 3-5 years of Azure experience. It covers the four design domains, identity/governance/monitoring, data storage solutions, business continuity, and infrastructure (the heaviest at 30-35%), teaching the decision-making the exam tests: choosing services, connecting them, handling failure, and controlling cost, with case-study practice and a strategy centred on understanding the why behind each design choice.

   5 flagged claims verified: an unverified 'Microsoft data 2024' ranking/salary claim was generalized; quotes attributed to Alex Weinert, Arun Ulag, and Mark Russinovich had no locatable source and were de-attributed to plain prose; an unverified resource 'Thomas Mitchell's AZ-305 Real World Scenarios' was removed.

   What the page claimed

   'Microsoft data from 2024 shows that the Azure Solutions Architect Expert is among the top three most in-demand Azure certifications... average advertised salary... ranges from $145,000 to $185,000' / "Permanent privileged role assignments are one of the highest-risk configurations..." -- Alex Weinert, VP of Identity Security at Microsoft / "Data architecture decisions made at design time are exponentially more expensive..." -- Arun Ulag, CVP Azure Data / "The architects who design the most effective Azure solutions are not the ones who know the most Azure services..." -- Mark Russinovich, CTO of Microsoft Azure / third-party case studies from 'Thomas Mitchell's AZ-305 Real World Scenarios'

   What was corrected

   The Azure Solutions Architect Expert is widely regarded as one of the most in-demand Azure certifications among employers, with roles requesting it tending to advertise senior-level salaries well above associate-level Azure roles (unsourced precise ranking/salary generalized). / Permanent privileged role assignments are one of the highest-risk configurations in any Azure tenant; organizations with PIM available should generally convert standing access to just-in-time access (unattributed prose). / Data architecture decisions made at design time are exponentially more expensive to change than compute architecture decisions (unattributed prose). / The architects who design the most effective Azure solutions are the ones who understand the tradeoffs, not the ones who know the most services (unattributed prose). / Removed the unverified resource entirely; replaced with 'reputable third-party case-study collections'. Also removed the now-orphaned Weinert reference-list citation.

   Why: An unverified 'Microsoft data 2024' ranking/salary claim was generalized since the precise figures were unverifiable. Quotes attributed to Alex Weinert, Arun Ulag, and Mark Russinovich had no locatable source and were de-attributed to plain prose. An unverified resource, 'Thomas Mitchell's AZ-305 Real World Scenarios', was removed since no such resource could be located.
