You have several App Service apps deployed in the West US region (details shown in a table). You need to ensure every app can access resources in a virtual network named VNet1 without routing traffic over the internet. How many integration subnets must you create?

The correct answer is 3. Each App Service plan (ASP) requires its own dedicated subnet for virtual network integration. The scenario implies there are three distinct App Service plans hosting the apps, even if some apps are within the same plan. Therefore, to ensure all apps can access VNet1 resources without internet routing, three integration subnets are needed, one for each App Service plan. Incorrect options: 0: This is incorrect because virtual network integration requires at least one subnet. 1: This is incorrect because multiple App Service plans cannot share a single integration subnet. 4 and 6: These are incorrect as the problem implies only three distinct App Service plans, each needing one subnet.
