The short version
Pick the 4-week plan if you already administer Azure and can give about 10 to 12 hours a week. Pick the 8-week plan if you are newer to design work or have 5 to 7 hours a week. These hours are rough. People vary a lot, so adjust after your first practice set. The plans follow the weightings in Microsoft’s skills measured as of April 17, 2026.
Before you start
- Read the AZ-305 study guide once and copy the domain list into a notes file. You will tick things off against it.
- Take a baseline: a free Microsoft practice assessment, or the first of our practice sets, cold. The score per domain tells you where to start, not whether you are good enough.
- Get an Azure subscription you can break. Even 15 minutes of clicking through a feature makes the design trade-offs stick.
The weightings set your time budget. Infrastructure is 30-35%, identity, governance, and monitoring is 25-30%, data storage is 20-25%, and business continuity is 15-20%.
The 4-week plan (about 10 to 12 hours a week)
| Week | Focus | What to do |
|---|---|---|
| 1 | Identity, governance, and monitoring | Authentication and authorization options, managed identities, Key Vault, management groups, Azure Policy, role assignments, logs and Azure Monitor routing. Finish with a practice set restricted to this domain. |
| 2 | Data storage and business continuity | Relational options and tiers, Cosmos DB consistency, blob tiers and protection, then backup, Site Recovery, RPO and RTO, and zone and region redundancy. |
| 3 | Infrastructure | Compute choices, messaging and events, API and caching options, migration tools, and networking: connectivity, load balancing, security. |
| 4 | Mixed practice and weak spots | Two full-length practice sets, review every explanation, then rework your weakest two domains. |
The 8-week plan (about 5 to 7 hours a week)
| Week | Focus | What to do |
|---|---|---|
| 1 | Foundations | Well-Architected Framework pillars, Azure regions and availability zones, and a baseline practice set. |
| 2 | Identity and authorization | Microsoft Entra options, guest access, role-based access, managed identities. |
| 3 | Governance and monitoring | Management groups and subscriptions, tags, Policy, logs, alerts, and routing. |
| 4 | Data storage | Relational services and tiers, scalability, semi-structured and unstructured storage, data integration. |
| 5 | Business continuity | Backup per workload type, disaster recovery, high availability for compute and data. |
| 6 | Infrastructure: compute and applications | VMs, containers, serverless, batch, messaging, events, APIs, caching, deployment. |
| 7 | Infrastructure: migration and networking | Migration planning and tools, connectivity, load balancing, network security. |
| 8 | Review | Two full-length sets, targeted rework, and a lighter final weekend. |
How to use practice exams in the plan
Use them to find gaps, not to collect scores. After each set, sort the questions you missed by domain, and ask whether you lacked a fact or missed a requirement in the stem. The first is fixed by reading; the second by slowing down.
A workable rhythm is one set cold at the start, one per week as a checkpoint, and two full-length sets in the final week. Do not retake the same set until you have studied. Memorizing answers inflates your score and hides gaps. Our AZ-305 practice tests run in five steps: core choices, neighboring services, trade-offs, tiers and settings, and a case-style set. Their pass marks of 80% (85% on the last set) are our own readiness bars, not Microsoft’s scoring. See how to study for IT certification exams for general method.
The last 3 days
- Three days out: Take a full-length set, then fix only the top three gaps. Do not start new topics.
- Two days out: Reread your notes on the service comparisons you confuse, such as messaging services, or storage redundancy options. Skim the Learn pages for the tiers you keep missing.
- The day before: Do 30 minutes of light review at most. Confirm your appointment, ID, and test setup. Try Microsoft’s exam sandbox if you have not used the interface. Sleep.
- Exam day: Read each stem for constraints (cost, recovery targets, residency, effort) before looking at options. Use the open Learn pane sparingly. The exam day guide has the rest.

Frequently asked questions
How many hours do I need in total?
Both plans land at roughly 40 to 55 hours, and newer candidates may need more. It is a guide, not a rule from Microsoft.
Should I study the domains in exam order?
Not necessarily. Start with your weakest, but do not skip identity and governance, because those concepts show up inside other domains.
Is hands-on practice required?
Microsoft recommends training and hands-on experience. Even short lab sessions help you remember why one design beats another.
