Who this exam is for

The Developing Solutions for Microsoft Azure certification is designed for professionals who work with or want to work with Microsoft technologies in a professional capacity. It is taken by cloud engineers, DevOps practitioners, IT administrators, and technical professionals looking to validate their expertise.

You do not need extensive prior experience to attempt it, but you will benefit from hands-on familiarity with the subject matter. The exam tests applied knowledge and architectural judgment, not just memorization. If you can reason about trade-offs and real-world scenarios, structured practice will handle the rest.

Domain breakdown

The AZ-204 exam is built around official domains, each with a fixed percentage of the question pool. This distribution should directly inform how you allocate your study time.

Domain

Weight

Focus areas

Develop Azure Compute Solutions

25-30%

Azure App Service (deployment methods, scaling, deployment slots, configuration), Azure Functions (triggers, bindings, durable functions orchestration patterns), Azure Container Apps, and Azure Container Registry.

Develop for Azure Storage

15-20%

Blob storage SDK operations (upload/download streams, metadata, leases, SAS token generation), Cosmos DB SDK (CRUD operations, partition key design, consistency levels, change feed processor), and Azure Table Storage.

Implement Azure Security

20-25%

Microsoft Entra ID authentication (MSAL, OAuth 2.0 authorization code and client credentials flows), Managed Identity (system-assigned vs user-assigned), Key Vault secrets/keys/certificates via SDK, App Service authentication middleware.

Monitor, Troubleshoot & Optimize Azure Solutions

15-20%

Application Insights (telemetry types, custom events, dependency tracking, sampling), Azure Cache for Redis (cache-aside pattern, eviction policies, data types), CDN caching rules and purge operations.

Connect & Consume Azure Services & Third-Party Services

15-20%

API Management (policies: rate-limit, rewrite-uri, set-header, set-body), Azure Event Grid (topics, subscriptions, filtering, retry policies), Azure Service Bus (queues vs topics, sessions for FIFO, dead-lettering), Azure Event Hubs (partitions, consumer groups, capture).

Note the domain with the highest weight — many candidates under-invest here because it feels conceptual. In practice, this is where the exam is most precise, with scenario-based questions that test specifics.

What the exam actually tests

This is not a memorization exam. Questions require applied judgment under constraints. Almost every question includes a scenario with explicit requirements and asks you to select the most appropriate solution.

Here are examples of the question types you will encounter:

Code-Based Scenario

You need to retrieve a secret from Key Vault in an Azure Function without storing credentials in code or configuration. Which authentication approach should you implement and what SDK class handles the token acquisition?

System-assigned Managed Identity is the correct answer. Use DefaultAzureCredential from Azure.Identity SDK — it automatically uses Managed Identity when running in Azure, and developer credentials locally.

Cosmos DB Configuration

An e-commerce application requires reads to always return the most recent committed write, even at the cost of higher latency and reduced throughput. Which Cosmos DB consistency level should you configure?

Strong consistency guarantees linearizability. Know all 5 levels in order from strongest to weakest: Strong > Bounded Staleness > Session > Consistent Prefix > Eventual. Session is the default and most common.

Messaging Service Selection

An order processing system requires that each order message is processed by exactly one consumer, supports FIFO ordering per customer (not globally), and needs dead-letter queue support for failed processing. Which service fits?

Azure Service Bus queues with sessions enabled (sessions provide FIFO per session key / customer ID). Not Event Hub (streaming, no dead-letter) or Event Grid (event routing, not guaranteed ordering).

How to prepare — 4-week study plan

This plan assumes one hour per weekday and roughly 30 minutes of lighter review on weekends. It is calibrated for someone with some relevant experience. If you are starting from zero, add an extra week before Week 1 to familiarise yourself with the basics.

Week 1: Compute & App Service

Study Azure App Service: deployment methods (Git local, GitHub Actions, ZIP deploy, FTP), deployment slots and traffic splitting, auto-scaling rules (metric-based and schedule-based)
Learn Azure Functions: HTTP trigger, Timer trigger, Blob trigger, Queue trigger, Service Bus trigger — know input/output binding syntax for function.json or attribute decorators
Study Durable Functions: orchestrator function (replay-safe), activity functions, entity functions — implement fan-out/fan-in, chaining, and human interaction patterns
Practice Azure Container Apps: environment configuration, ingress (internal vs external), scaling rules (HTTP, CPU, custom KEDA), Dapr sidecar integration basics

Week 2: Storage & Cosmos DB

Master Blob Storage SDK: BlobServiceClient, BlobContainerClient, BlobClient — upload/download streams, set/get metadata, acquire leases, generate SAS tokens with BlobSasBuilder
Study Cosmos DB: partition key selection (high cardinality, evenly distributed), point reads (ReadItemAsync by id + pk) vs queries (query cost in RUs), RU/s calculation
Learn all 5 Cosmos DB consistency levels with concrete examples: Strong for financial transactions, Session for shopping carts, Eventual for social media likes
Study Cosmos DB change feed: change feed processor library (ChangeFeedProcessor), lease container, and how to trigger Azure Functions via Cosmos DB trigger binding

Week 3: Security, Auth & Messaging

Implement Managed Identity: enable system-assigned on App Service/Function App, assign Key Vault Secrets User role, access secrets using SecretClient with DefaultAzureCredential
Study OAuth 2.0 flows in detail: authorization code flow (user-facing apps), client credentials flow (service-to-service daemons), on-behalf-of flow (API calling another API on user behalf)
Learn Service Bus SDK: ServiceBusClient, send messages (ServiceBusMessage), receive (ServiceBusReceiver peek-lock vs receive-and-delete), complete/abandon/dead-letter, topic subscriptions with SQL filters
Study Event Grid vs Event Hubs vs Service Bus decision matrix: throughput (Event Hubs), guaranteed delivery and ordering (Service Bus), event routing fan-out (Event Grid)

Week 4: Monitoring, APIM & Mock Exams

Configure Application Insights: track custom events (TelemetryClient.TrackEvent), custom metrics, dependencies, set sampling rate (adaptive vs fixed), create availability tests
Implement Azure Cache for Redis: connect with StackExchange.Redis ConnectionMultiplexer, implement cache-aside pattern, set TTL (TimeSpan expiry), handle connection resiliency with retry policy
Study API Management policies in detail: inbound (validate-jwt, rate-limit-by-key, set-header), backend (rewrite-uri), outbound (set-body with liquid templates) — know XML policy syntax
Take all 6 mock exams focusing on code scenarios; re-read the Managed Identity section and Cosmos DB consistency levels before sitting the exam

Common mistakes candidates make

These patterns appear repeatedly among candidates who resit this exam. Knowing them in advance is worth several percentage points.

Not understanding Managed Identity vs Service Principal

Managed Identity is always the exam-preferred answer for "how should an Azure resource authenticate to another Azure resource." System-assigned ties to the resource lifecycle (deleted with the resource). User-assigned is independent and can be shared across multiple resources. Service Principals require manual credential rotation and secret management.

Confusing Azure Functions triggers and bindings

Triggers define what causes a function to execute (exactly one trigger per function). Bindings are declarative connections to other services (zero or more, input and/or output). You cannot have two triggers but can have multiple input and output bindings. Know the binding expressions syntax (e.g., {queueTrigger} in blob path).

Weak on Cosmos DB consistency levels

All 5 consistency levels appear in exam scenarios with specific business requirements. Strong = linearizable reads, highest latency, lowest throughput. Eventual = lowest latency, possible stale reads, highest throughput. Session (default) = monotonic reads within a session, most common practical choice.

Not studying SAS token types and when to use each

Shared Access Signatures have three types with distinct use cases: Account SAS (access to multiple services, created with storage account key), Service SAS (one service, created with storage account key), User Delegation SAS (uses Entra ID credentials, most secure, preferred for production). The exam tests which is most appropriate given security requirements.
