K4 prepares you for the exam AZ-305. That is an offer, not an obligation: The course teaches how to cut systems and justify decisions, and many who finish it never take an exam. If you want to, you should know where the course meets the exam and where it does not. AZ-305 is broader than a course about .NET systems: It also asks about virtual machines, connections to on-premises data centers and migrations, none of which ever come up in the Kladde.
This lesson lays the two side by side. In the end, you have an honest rating per topic group and a study plan for the gaps. We are not a Microsoft training partner; what is said here about the exam is said that way on Microsoft Learn, and you should read it there again before any planning.
The exam in brief
| Question | Answer |
|---|---|
| Name | AZ-305: Designing Microsoft Azure Infrastructure Solutions |
| Certification | Microsoft Certified: Azure Solutions Architect Expert |
| Prerequisite | an active Azure Administrator Associate certification (exam AZ-104); K3 prepares for it. According to answers on Microsoft Q&A, AZ-305 may also be taken beforehand; the certification is only awarded with both |
| Passing | from 700 points |
| Validity | Expert certifications expire annually; renewal is a free online assessment on Microsoft Learn |
| Trying it out | the “exam sandbox” shows the exam's interface without content; a practice assessment shows questions in the style of the exam; the current one is in the AI Skills Navigator, the older one on Microsoft Learn is no longer maintained (read on November 11, 2026) |
| Language | not every exam exists in every language; if yours is missing, you can request 30 minutes more time |
Microsoft's study guide for AZ-305 is the source for everything that follows. It describes the role that is tested: Whoever designs solutions in Azure translates requirements into designs following the Well-Architected Framework and the Cloud Adoption Framework, and works with development, operations, security and data people to do so. That is the role K4 practices.
Two things in the guide you should check every time before you plan:
- Since when the version applies. Above the “Skills measured” there is a date, on November 11, 2026 it was April 17, 2026. Microsoft adjusts the content regularly; what has changed is in the change log at the end of the guide.
- Which practice assessment is current. At the top, the guide says where the practice assessment can currently be found, and whether an older version is no longer maintained.
