This az 305 study plan allocates study time in proportion to Microsoft's published domain weights: design infrastructure solutions (32%), identity, governance, and monitoring solutions (28%), data storage solutions (22%), and business continuity solutions (18%). Whichever schedule length you pick, spend the most time on infrastructure and identity, since together they make up most of the exam.
How this AZ-305 study plan is weighted
Microsoft weights the four AZ-305 domains at 28%, 22%, 18%, and 32%. A study plan that ignores those weights and splits time evenly across domains under-prepares you for design infrastructure solutions and identity, governance, and monitoring solutions, which together make up well over half the exam. This az 305 study plan spends time roughly in proportion to those weights, then adjusts for the fact that business continuity, while the smallest domain, is tested in enough depth to deserve a dedicated block of its own.
| Domain | Weight | Study emphasis |
|---|---|---|
| Design infrastructure solutions | 32% | Highest priority: compute, application architecture, migrations |
| Design identity, governance, and monitoring solutions | 28% | High priority: logging, authentication, governance |
| Design data storage solutions | 22% | Medium priority: relational, unstructured, and integration |
| Design business continuity solutions | 18% | Focused priority: backup, recovery, high availability |
Four-week plan
A four-week plan works if you already have solid Azure design experience and mainly need to close gaps and build exam pacing.
- Week one: Design infrastructure solutions and design identity, governance, and monitoring
solutions. These two domains cover most of the exam, so front-load them.
- Week two: Design data storage solutions, then design business continuity solutions. Work
through every objective statement on the AZ-305 exam objectives page for both domains.
- Week three: Full review across all four domains, focused on the objective statements you
found hardest to reason through in weeks one and two.
- Week four: Timed practice under exam-like conditions using the
AZ-305 practice test, then a final pass on any domain where your score fell short.
Eight-week plan
An eight-week plan gives you room to study each domain twice: once to learn it, once to reinforce it.
- Weeks one and two: Design infrastructure solutions, split across compute design, application
architecture, and migrations, since this domain alone spans fourteen objective statements.
- Weeks three and four: Design identity, governance, and monitoring solutions, covering logging,
authentication and authorization, and governance structure.
- Weeks five and six: Design data storage solutions and design business continuity solutions,
one domain per week.
- Week seven: Full-syllabus review, working problem by problem through our
AZ-305 sample questions to see how the objective statements translate into exam-style scenarios.
- Week eight: Two full timed mocks with the AZ-305 practice test,
reviewing every missed question's explanation before you book your exam.
Twelve-week plan
A twelve-week plan suits candidates who are newer to design-level Azure work and need time to build comfort with trade-off reasoning, not just service names.
- Weeks one through three: Design infrastructure solutions, moving slowly through compute
options, application architecture patterns, and migration planning using the Cloud Adoption Framework.
- Weeks four through six: Design identity, governance, and monitoring solutions, spending extra
time on authentication and authorization, since it is the largest sub-area within this domain.
- Weeks seven and eight: Design data storage solutions, covering relational and non-relational
storage and data integration.
- Weeks nine and ten: Design business continuity solutions, working through backup, recovery,
and high-availability scenarios for compute and data.
- Week eleven: Full review, plus a first attempt at the
AZ-305 practice test to identify remaining gaps.
- Week twelve: Targeted review on your weakest domain from week eleven's mock, followed by a
second full timed mock before you book through AZ-305 cost and booking.
Adjusting the plan to your own pace
None of these schedules are fixed. If a mock score shows you are already strong in a domain, shift that block's time to a weaker one instead. Revisit the AZ-305 prerequisites page if you are unsure whether your background matches what the exam assumes before you commit to a shorter plan.
