Azure App Service web apps

Week 2

10-12 hours this week

Deploy a web app three ways: zip deploy, GitHub Actions and a container image
Create a staging deployment slot, swap it, and record which app settings stayed with the slot and which followed the code

Turn on application logging, web server logging and failed request tracing, then read the output in the log stream

Containers on Azure

Week 3

10-12 hours this week

Build a Docker image locally, push it to Azure Container Registry, and run it with Azure Container Instances
Deploy the same image to Azure Container Apps and configure ingress, revisions and scale rules including scale to zero
Compare Container Instances, Container Apps and App Service for containers in a written table so you can answer selection questions fast
Use an ACR task to build an image in the cloud rather than locally
Grant Container Apps pull access to ACR using a managed identity instead of admin credentials

Add input and output bindings for Cosmos DB and Queue Storage without writing SDK client code
Compare the Consumption, Flex Consumption, Premium and Dedicated hosting plans on cold start, scaling and VNet support
Use Durable Functions to build one chained and one fan-out fan-in orchestration

Azure Cosmos DB

Week 5

Write out the five consistency levels in order from strongest to weakest with the guarantee and the cost of each
Build a change feed processor and observe how it reacts to inserts and updates but not deletes
Deliberately choose a bad partition key, generate a hot partition, and watch request unit throttling in the metrics blade
Compare provisioned throughput, autoscale and serverless capacity modes

Azure Blob Storage

Week 6

8-10 hours this week

Upload, download, list and delete blobs using the storage SDK rather than the portal
Set custom metadata and system properties on a blob and read them back in code
Write a lifecycle management policy that moves blobs from hot to cool to archive and confirm the rule fires
Generate a service SAS, an account SAS and a user delegation SAS, and note the differences in what signs them and how they are revoked
Enable soft delete and versioning, then recover a deleted blob

Identity, Key Vault and managed identities

Week 7

10-12 hours this week

Register an application in Microsoft Entra ID and sign a user in with MSAL using the authorization code flow
Call Microsoft Graph with delegated permissions and again with application permissions, and record which consent each needs
Store a secret and a certificate in Key Vault, then read both from an App Service web app using a system-assigned managed identity
Assign a user-assigned managed identity to two resources and explain when that is preferable to a system-assigned one
Trace how DefaultAzureCredential resolves locally versus in Azure and configure Azure App Configuration with Key Vault references

Messaging, events and API Management

Week 8

10-12 hours this week

Build one working sample each with Event Grid, Event Hubs, Service Bus and Queue Storage
Write a one-page decision table covering ordering, sessions, dead-lettering, retention and throughput for those four services

Timed rehearsal and gap closing

Week 10

10-12 hours this week

Sit a full timed practice test from MeasureUp or Whizlabs under 100-minute conditions with no notes
Rebuild every lab you got wrong rather than rereading the explanation
Practise finding three specific answers on learn.microsoft.com in under 90 seconds each, since the exam gives you Learn in a split-screen panel but adds no extra time
Reread the Exam Ref AZ-204 chapters covering your two weakest skill areas
Run the Pearson VUE OnVUE system test on the exact machine and network you will use if testing from home
