How to Tackle the AZ-305 Azure Solutions Architect Expert Exam
If you are staring at the AZ-305 blueprint wondering how I pass a design exam that expects architect-level judgement rather than memorised facts, you are asking the right question. AZ-305, Designing Microsoft Azure Infrastructure Solutions, sits at the expert tier, and it rewards people who can weigh trade-offs across identity, storage, resilience, and infrastructure. This guide walks through the format, the domain weighting, and a preparation approach built around a good AZ-305 mock test.
What the exam actually asks of you
AZ-305 is a design exam. You are handed requirements and constraints and asked to choose the design that best satisfies them, which usually means the option that is technically correct and appropriate for the scenario. Two answers can both work; only one fits the stated cost, security, or availability requirement. That is the muscle you need to train, and it is different from the recall-heavy associate exams.
Format and timing
Microsoft does not publish a fixed question count for AZ-305, so treat any specific number as an estimate. Our practise exam runs 50 questions across 100 minutes, which works out to roughly 120 seconds per question. That pacing is deliberate: design scenarios come with a paragraph or two of context, and you need reading time before you can reason about the options. The exam is delivered linearly, meaning you move forward through the questions rather than in an adaptive or randomised block.
The pass standard is Microsoft's own: you need 700 on a scale that runs from 0 to 1000. That scale is not a raw percentage, so do not assume 700 means seventy percent of items correct. Aim comfortably clear of the line in practice.
Domain weighting
The exam covers four functional groups, and the weightings tell you where to concentrate. Infrastructure design is the single largest area, followed closely by identity, governance, and monitoring. The weights below come from Microsoft's published AZ-305 study guide, verified on 24 August 2026.
| Functional group | Weight |
|---|---|
| Design infrastructure solutions | 32% |
| Design identity, governance, and monitoring solutions | 28% |
| Design data storage solutions | 22% |
| Design business continuity solutions | 18% |
Notice that no domain is small. Business continuity is the lightest at 18%, but that still means a meaningful block of questions on backup, recovery objectives, and high availability. A balanced study plan beats cramming one favourite area.
What the mock contains, honestly
Here is the plain version of what our AZ-305 mock test does and does not do. The real AZ-305 may include interactive components: tasks you carry out against the product rather than answer as multiple choice. Our mock is multiple-choice and multiple-response only. It covers every functional group at its published weighting, so your topic coverage is faithful, but you will not practise the interactive interface itself. Knowing that in advance means no surprises on exam day. Use the mock to sharpen your design reasoning and your pacing, then read Microsoft's documentation for anything hands-on.
If you want that focused, weighted practice, you can buy a mock test pack and sit timed attempts under exam conditions.
How to prepare
Start with the largest domains and work down. Build small Azure designs yourself, even on a free tier, so the services stop being abstractions. Then run a timed practise exam for Azure architect readiness and review every wrong answer until you understand why the correct design won, not just that it did. That review step is where most of the learning happens.
Watch your clock. At two minutes per item you cannot afford to freeze on a long scenario. Flag it, move on, and return. Repeated timed sittings train that instinct better than any amount of reading. You can compare pack options and get a mock test pack that matches how many attempts you want.
