Azure AZ-305 FAQ: Exam Format and Prep

Azure AZ-305 FAQ for exam format, topics, prep strategy, practice, and common candidate traps.

RBAC: Role-based access control for Azure resource authorization.

DR: Disaster recovery, the design and process for restoring service after a major failure.

RTO / RPO: Recovery Time Objective and Recovery Point Objective, the recovery targets that drive Azure continuity design.

What is AZ-305 and who should take it?

AZ-305 validates solution architecture decisions in Azure: identity/governance/monitoring, data services, business continuity, and infrastructure design. It’s for architects and senior engineers who translate requirements into Azure designs that are secure, reliable, and cost-aware.

How is AZ-305 different from AZ-104?

AZ-104 is operational (configure and run Azure). AZ-305 is design-heavy (choose the right services and justify trade-offs). AZ-305 assumes you understand operational realities (monitoring, backup, RBAC scopes), but tests your ability to select architectures.

What kind of candidate is this exam really for?

AZ-305 is strongest for people who can already:

  • translate business constraints into Azure architecture choices
  • choose between managed and self-managed patterns without drifting into unnecessary complexity
  • reason clearly about governance scope, private access, continuity, and data-platform fit
  • justify a design in terms of availability, security, latency, operations, and cost

If you answer like an administrator doing the task step-by-step instead of an architect selecting the design, you will often miss the better answer.

Do I need AZ-104 first?

You can usually sit AZ-305 without AZ-104, but to earn Azure Solutions Architect Expert, you must hold Azure Administrator Associate (AZ-104) and pass AZ-305. Always confirm current requirements on Microsoft Learn.

How many questions and what is the passing score?

The passing score is typically 700/1000 (scaled). Question count and format vary (MCQ/MR, case studies, drag-and-drop). Expect scenario wording that forces trade-offs.

What domains are tested?

  • Identity, governance, monitoring (log routing, IAM design, policies/management groups)
  • Data storage (relational services, NoSQL, unstructured storage, integration/analytics)
  • Business continuity (backup/restore, DR, high availability)
  • Infrastructure (compute selection, application architecture, migrations, networks)

What does the exam punish most often?

Failure pattern Better instinct
solving the scenario with the most complex architecture instead of the simplest viable one prefer the least operationally heavy managed design that satisfies the constraints
mixing RBAC, Policy, landing-zone scope, and network decisions into one blur separate identity, governance, connectivity, and runtime concerns
using backups to answer strict continuity requirements map the requirement to RTO / RPO first, then decide between restore, standby, or failover
picking a data platform by brand familiarity instead of workload shape classify OLTP, document, analytics, object, or file needs first
adding private access without thinking through DNS and routing treat name resolution and network path as part of the design, not cleanup work

Are labs required?

Hands-on work helps, but AZ-305 is not “lab-y.” You should be able to design from first principles, and it’s much easier if you’ve built a small reference stack: hub-spoke VNet, Private Endpoints, a workload with App Insights + Log Analytics, a relational DB, a storage account with lifecycle rules, and a basic DR story.

What is the minimum useful hands-on baseline?

You do not need a huge estate. A solid minimum baseline is being able to explain:

  • one hub-spoke or private-access pattern and what DNS changes it requires
  • one relational-data choice and one non-relational-data choice
  • one continuity design in terms of RTO / RPO
  • one monitoring and log-routing pattern with Azure Monitor, Log Analytics, and Application Insights

How long does it take to prepare?

With strong Azure exposure: 3–5 weeks part-time. If you’re new to Azure, it’s better to do AZ-900 → AZ-104 → AZ-305 rather than jumping straight to architecture patterns.

What are the most common weak spots?

  • Picking the wrong front door: Front Door vs App Gateway vs LB vs Traffic Manager
  • Confusing RBAC vs Policy vs Locks (access vs compliance vs deletion protection)
  • Under-designing DR (backups only) or over-designing it (too complex/expensive)
  • Data service selection (SQL DB vs MI vs SQL VM; Cosmos partitions/consistency)
  • Missing DNS and routing details for private access patterns

How should you review misses?

If the miss was really about… Fix it by doing this next
governance scope redraw the hierarchy first: management group -> subscription -> resource group -> resource
data-platform fit restate the workload type and operational constraint before naming a service
continuity write the RTO / RPO target, then decide whether backup, geo-replication, or failover is actually required
ingress or private access classify the path as global, regional L7, regional L4, DNS-only, or private endpoint first
monitoring separate metrics, logs, traces, and archive/export paths before picking a product

Any last-mile tips?

  • For every scenario, write: Availability target, data sensitivity, latency, region scope, budget. Then choose the simplest design that satisfies those constraints.
  • Treat the cheat sheet as a set of decision trees, not a glossary.
  • In practice review, convert misses into one-line rules (e.g., “Need ordered queue + transactions → Service Bus”).

What should you not over-study?

Do not disappear into:

  • deep implementation detail that belongs more to AZ-104 or service-specialist docs
  • exhaustive SKU memorization when the exam is really testing architectural fit
  • edge-case product features that never change the main design decision

Which official source wins if another page disagrees?

Use the current Microsoft Learn AZ-305 exam page and study guide as the source of truth. As of April 13, 2026, Microsoft says the English-language exam updates on April 17, 2026, so if your exam is near that date, re-check the live study guide before booking or final review.
