You have web apps in West US, Central US, and East US and several App Service plans. You want to create a new Linux App Service plan named ASP5. In which of the currently used regions can you deploy ASP5?

You can deploy a new App Service plan (ASP5) to any Azure region where you currently have web apps running, which are West US, Central US, and East US. An App Service plan defines a set of compute resources for an app to run, and these resources are tied to a specific Azure region. Therefore, to host a new web app in one of these regions, you would create an App Service plan within that same region. The other options are incorrect because they limit the deployment to only one specific region, whereas Azure allows you to create App Service plans in any region where you have existing resources or where the service is available.
