Explanation

App Service plans must be selected based on matching the web app's required Azure region and operating system compatibility for its runtime stack.

Approach. Azure Web Apps must be deployed to an App Service plan residing in the exact same location (region). Based on the correct solution provided: WebApp1 is assigned to 'ASP1 and ASP3 only'. This indicates WebApp1 must be deployed to 'West US' and uses a cross-platform runtime stack (such as .NET Core, Node.js, or Python) that is supported on both Windows (ASP1) and Linux (ASP3). WebApp2 is assigned to 'ASP1 only'. This indicates it must be deployed to 'West US' but requires a Windows-exclusive runtime (such as ASP.NET V4.8), making ASP1 the only eligible plan.

Common mistakes.

  • common_mistake. Selecting ASP2 for either web app is incorrect because ASP2 is located in 'Central US', while the web apps require 'West US'. Selecting ASP3 for WebApp2 is incorrect because Linux App Service plans cannot host apps built on Windows-only frameworks like traditional ASP.NET.

Concept tested. Azure App Service plan constraints, specifically Region/Location matching and Operating System to Runtime Stack compatibility.
