Prepare for AZ-305 by turning each current objective into a design decision: identify the requirements, compare suitable options, and explain which constraints rule out the alternatives. Use the four-area map and worked recovery example below, then review your gaps against Microsoft’s full study guide and documentation.

What do you need for the Expert certification?

To earn Microsoft Certified: Azure Solutions Architect Expert, you need both the Azure Administrator Associate certification and a pass in AZ-305.

The architect role translates business requirements into Azure cloud and hybrid designs covering compute, networking, storage, monitoring, and security. Microsoft’s profile names the Azure Well-Architected Framework and Cloud Adoption Framework for Azure.

Microsoft expects advanced IT operations knowledge and experience with Azure administration, development, and DevOps processes. Use that profile to assess your preparation; it is separate from the named certification requirement. Check your current credential record before planning your path.

What should you study for AZ-305?

The English objectives dated April 17, 2026 cover four design areas. Use the full official outline to check detailed coverage.

The table combines official topics with suggested practice. Weight ranges describe emphasis, not exact question counts or required study hours. English updates come first; check the version and available language for your appointment.

Skill areaWeightTopics and suggested practice
Identity, governance, and monitoring25–30%Logging and log routing; authentication, identities and authorization; secrets, certificates and keys; management groups, subscriptions, resource groups, tagging, compliance and identity governance. Sketch a proposed organization and explain the requirements behind each design decision.
Data storage20–25%Relational, semi-structured and unstructured data; database service and compute tiers, scalability, protection, durability, performance and cost; data integration and analysis. Compare two documented options against a written set of workload requirements.
Business continuity15–20%Backup and recovery for Azure and hybrid compute, databases and unstructured data; high availability for compute and data. Check a proposed solution against every stated recovery target, as in the example below.
Infrastructure30–35%Virtual machines, containers, serverless and batch compute; messaging, events, APIs, caching, application configuration and deployment; migration assessment and data migration; connectivity, network performance, security, load balancing and routing. Explain a design and identify which requirement would make you change it.

Practice comparing recovery options

Check every stated requirement before selecting a recovery design. A better result on one measure does not cancel a failed requirement elsewhere.

NIST defines the recovery point objective (RPO) as the point in time to which data must be recovered after an outage. The recovery time objective (RTO) concerns how long system components can remain in recovery before harming the organization’s mission or business processes.

In this original exercise, the RPO limit is expressed as the maximum age of recoverable data and the RTO limit as the maximum restoration time. The options are fictional; their figures do not describe Azure service levels or prices.

One original, fully specified practice exercise with fictional figures.

A fictional retailer requires recoverable data no older than 15 minutes, service restored within 60 minutes, and a monthly recovery-design cost no higher than 200 fictional units. The complete option figures are A: 5 minutes, 90 minutes, 100 units; B: 10 minutes, 45 minutes, 180 units; C: 0 minutes, 30 minutes, 260 units. Treat these estimates as accurate for this exercise. Which option satisfies all three limits, and why do the others fail?

The exercise answer and full explanation follow the prompt.

Option B satisfies all three limits: 10 ≤ 15 minutes, 45 ≤ 60 minutes, and 180 ≤ 200 units. A fails the restoration-time limit because 90 > 60. C fails the cost limit because 260 > 200.

Compare each option with each maximum independently. Faster recovery or more recent data does not override the stated cost ceiling. The example tests constraint checking; applying the method to a real workload also requires current service documentation, a complete set of requirements, and validated estimates.

Build a practical study checklist

For each objective, write a requirement, propose a solution, and explain your decision using current documentation.

Microsoft recommends training and hands-on experience. Its official practice assessment provides answer rationales and links for further reading, but does not reproduce the exam’s questions, length, or complexity. Use it to identify gaps alongside practical study.

  • Mark the current outline by what you can explain, what you have practised, and what still needs work.
  • For each weak area, compare two plausible options and state the requirement that favors one. Verify service behavior in the linked Azure documentation.
  • Where you have an authorized learning environment, test relevant tasks. If access is unavailable, trace a documented example and record what you still need to practise.
  • After practice questions, explain why each rejected option fails the stated requirement. Return to the objective when your explanation is incomplete.
  • Explore the exam sandbox to learn the interface, then confirm your prerequisite credential, appointment details and regional fee.

What should you expect on exam day?

AZ-305 is proctored. The passing standard is 700 or higher on Microsoft’s scaled 1–1,000 range; it is not a raw 70% score.

The reviewed AZ-305 page does not confirm an exam-specific duration. Microsoft’s general policy lists 100 minutes of exam time and a 120-minute appointment for associate/expert exams without labs, or 120 and 140 minutes respectively for exams that may contain labs. Confirm your appointment and exam overview; do not assume a fixed question count or that a lab will appear.

Follow the scoring instructions for each item. Microsoft says there is no penalty for guessing, and unscored questions are not identified to candidates.

  • Built-in Microsoft Learn access is restricted to learn.microsoft.com, excluding Q&A, practice assessments and your profile. Other domains are blocked; browsing adds no exam time.
  • Five minutes for breaks are already included in exam time. The clock continues during a break, and you cannot return to previously viewed questions, including unanswered or flagged ones.
  • Confirm the regional price at booking and use the current instructions for accommodations and check-in. Microsoft recommends registering with a personal account to avoid losing access through an employer or school account.

How do renewal and retakes work?

The credential is initially valid for one year. Renewal uses a separate free, open-book, unproctored assessment on Microsoft Learn.

The renewal window opens six months before expiration. Passing before expiry extends the certification one year from its existing expiration date. Check the date in your profile; an expired credential must be re-earned under the applicable requirements.

For a failed AZ-305 exam, the standard wait is 24 hours after the first attempt, then 14 days between subsequent attempts. The maximum is five attempts in a 12-month period from the first attempt. These exam-retake rules are separate from the renewal assessment policy.

FAQ

Frequently Asked Questions

Practical answers to help you apply the guidance for Microsoft Certified Azure Solutions Architect Expert (AZ-305).

Do I have to earn AZ-900 for the Expert certification?
AZ-900 is not listed among the requirements for Azure Solutions Architect Expert. The named prerequisite is Azure Administrator Associate, alongside AZ-305. Fundamentals learning may help with gaps, but it does not replace those requirements.
Can AZ-305 include preview features?
Microsoft says most questions cover generally available features, while commonly used preview features may appear. Follow the current objectives and linked documentation rather than excluding a listed topic solely because it has a preview label.
