Practice results settle AZ-305 readiness the same way the exam does, by the design you choose from the stated constraints. As a CramHQ rule of thumb, you are probably ready when your last two fresh, timed results sit around 80% or better and no domain still shows up as a gap. You are not ready yet when a higher score is built on questions you have seen before, or when you cannot explain a wrong answer without the explanation open.
Microsoft reports technical exam results on a scaled score from 1 to 1,000, with 700 or greater required to pass (Microsoft exam scoring and score reports). That does not mean you need exactly 70% of the questions correct. The scoring page says the scaled score may not equal 70% of the points. The exam measures design work across four domains: design identity, governance, and monitoring solutions; design data storage solutions; design business continuity solutions; and design infrastructure solutions (Microsoft AZ-305 exam page).
Only count practice tests that were actually new
Use your last two mixed practice exams. Count them only if:
- You had not seen the questions before.
- You completed each exam in one sitting without documentation or search.
- You used a realistic time limit.
- The set covered all four AZ-305 domains.
- You chose answers from requirements rather than remembered wording.
Repeated questions are useful for learning service capabilities. They are poor readiness evidence once you remember that a scenario's answer was Cosmos DB, Front Door, or a particular disaster-recovery design. A fresh question should force you to rebuild the decision from availability, consistency, latency, security, operational, and cost constraints.
Audit every wrong architecture decision
For every wrong answer, answer four questions:
- Which requirement was decisive?
- Which requirement did my answer fail?
- What tradeoff makes the correct design preferable here?
- Would my choice change if one important constraint changed?
Then label the wrong answer:
- Missing capability: You did not know a service feature, limitation, or integration.
- Boundary confusion: You could not separate two plausible design choices.
- Constraint miss: You ignored a requirement such as recovery time, data residency, private access, consistency, or minimizing operations.
- Implementation drift: You chose the detailed configuration step instead of the architecture the question asked you to recommend.
AZ-305 is not a service-name recall test. If the explanation only tells you what the right service does, your review is incomplete. You also need to know why the other design fails the scenario.
Know what a weak domain looks like
Microsoft's current study guide lists these weights for skills measured as of April 17, 2026:
| Area | Exam weight | Signs you should keep studying |
|---|---|---|
| Design identity, governance, and monitoring solutions | 25-30% | You recommend broad access, mix identity with network controls, ignore management-group or subscription boundaries, or choose monitoring components without tracing collection, analysis, alerting, and response. |
| Design data storage solutions | 20-25% | You choose a database by familiarity instead of data model, query pattern, consistency, scale, availability, retention, security, and migration requirements. |
| Design business continuity solutions | 15-20% | You treat backup, high availability, and disaster recovery as interchangeable or ignore recovery time and recovery point requirements. |
| Design infrastructure solutions | 30-35% | You jump to a compute or network product before resolving traffic flow, integration, migration, deployment, resiliency, management, and cost constraints. |
The ranges come from the official AZ-305 study guide. Check it again near your exam date because Microsoft can update the measured skills. The exam reports one overall scaled score (Microsoft exam scoring and score reports), so there is no per-domain minimum to chase. What you do need is to recognize when the same design failure appears under different product names.
Check that you can design before seeing the options
Cover the choices and outline a defensible design for tasks such as:
- Give multiple teams delegated Azure access while keeping central governance and policy enforcement.
- Select a data store for globally distributed reads and writes with an explicit consistency requirement.
- Design recovery for an application with a short recovery time and limited acceptable data loss.
- Expose an internet application globally while protecting it and routing users to healthy regional deployments.
- Collect platform and application telemetry, retain it appropriately, and route actionable conditions to responders.
- Migrate a workload while minimizing downtime and limiting changes to the application.
Your answer does not need every portal setting. It should name the architecture, the decisive constraint, the main tradeoff, and the failure mode it addresses.
Why the same score can mean two different things
Suppose two candidates score 78%.
The first misses an unfamiliar retention option, one migration-tool capability, and several unrelated service details. They can reconstruct the right designs once those facts are corrected. They are probably close.
The second candidate performs well on identity and storage but repeatedly misses business continuity. They choose backup when the requirement is rapid regional failover, add availability zones when the requirement covers a regional outage, and never use the stated recovery objectives. That 78% is hiding an architecture gap. They should wait.
The useful question is not only how many points you lost. It is whether the same reasoning error survives across different scenarios.
When to book AZ-305
Schedule the exam when all of the following are true:
- Two fresh, timed results are around 80% or better, allowing for test difficulty.
- No major domain repeatedly collapses under unfamiliar scenarios.
- You can identify the decisive requirement before looking at the answers.
- You can explain the tradeoff and the failure in your rejected choice.
- You can solve a changed version when region, scale, recovery, identity, or cost constraints move.
- You finish at a steady pace without guessing through the final scenarios.
Wait if you select services by keyword, if you cannot state the tradeoff, or if explanations make sense only while you are reading them.
In the final few days, group mistakes by reasoning pattern rather than service name. Repair the two patterns costing the most points, then use one final mixed exam to see whether they return.
Get a more useful result than a percentage
Take the free AZ-305 assessment. It is free and needs no credit card, and it returns a Readiness Report with your top gaps, so you can see which architecture decisions are costing you points. The report also includes a targeted repair preview, which points at the first focused fix instead of sending you back through the whole syllabus. The paid course path costs US$34.99 for 12 months of access and includes the Pass Plan. It is the heart of the paid path: your targeted repair tasks, ranked into a single list. After the assessment starts you off, CramHQ fills that list from your practice over time, pricing each gap in the exam points it costs, so the priciest one sits first. Each repair task names the design trap that cost you the points, the rule that sidesteps it, a worked example, and a retest on questions you have not seen. The practice tests and the timed final simulation check your readiness, and your first repair is free.
FAQ
Is a 70% practice score enough for AZ-305?
Do not book from that number alone. Microsoft's 700 passing score is scaled, and it is not the same as 70% of the questions correct (Microsoft exam scoring and score reports). Fresh questions and consistent architecture reasoning are stronger evidence.
Is AZ-305 an implementation exam?
All four domains on the exam are design tasks: design identity, governance, and monitoring solutions; design data storage solutions; design business continuity solutions; and design infrastructure solutions (Microsoft AZ-305 exam page). The central task is choosing and justifying designs from the stated requirements, not reciting configuration steps.
Does passing AZ-305 by itself earn the Azure Solutions Architect Expert certification?
No. Microsoft currently lists the Azure Administrator Associate certification as a prerequisite and AZ-305 as the required exam for the Azure Solutions Architect Expert certification. If you still need that prerequisite, the AZ-104 course covers the Azure Administrator exam.
When should I take my final practice exam?
One to three days before the real exam is a useful window. It gives you time to fix a narrow reasoning gap without restarting the entire course.
