Which TWO tools can you use to perform this assessment? (Select TWO)

Answer options:

App Service Migration Assistant

Azure Migrate: App Containerization

C.

How to approach this question

Identify the tools specifically designed for assessing and migrating web applications to Azure PaaS/Containers.

Full Answer

To migrate an IIS web application to Azure App Service (PaaS), you must ensure the app doesn't rely on OS-level features not supported in PaaS (like COM components or GDI). The App Service Migration Assistant is a standalone tool that scans the IIS configuration and code to provide a readiness report. Alternatively, the Azure Migrate: App Containerization tool can assess the ASP.NET application and help package it into a container, which can then be deployed to App Service or AKS.

Common mistakes

Selecting Data Migration Assistant (DMA), which is strictly for database assessments, not web applications.
