Use versioned artifacts — keep your last working package and redeploy it. Example: If your new API build breaks production, you can quickly redeploy the previous successful release version from Azure DevOps → Releases → “Redeploy”. 8⃣ How do you deploy infrastructure using ARM templates or Bicep in Azure DevOps?

Short answer: You can deploy Infrastructure as Code (IaC) directly from your pipeline using ARM or Bicep files.

Explain a bit more

Follow: Example (YAML): task: AzureResourceManagerTemplateDeployment@3 inputs: deploymentScope: 'Resource Group' azureResourceManagerConnection: 'MyServiceConnection' subscriptionId: 'xxxx-xxxx-xxxx' action: 'Create Or Update Resource Group' resourceGroupName: 'my-rg' location: 'East US' templateLocation: 'Linked artifact' csmFile: 'infrastructure/main.bicep' overrideParameters: '-appName myapp -sku S1' Example scenario: Before deploying your .NET app, your pipeline provisions a new App Service, SQL Database, and Storage Account automatically.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
