Question Image

You plan to create an Azure web app named WebApp2 with these settings:

  • Region: East US
  • VNet integration: Enabled
  • Scale out: Autoscale to up to 10 instances

For each statement below, select Yes if it is true. Otherwise, select No.

Yes or No
StatementsYesNo
WebApp2 can be integrated with Subnet11.
WebApp2 can be integrated with Subnet12.
WebApp2 can be integrated with Subnet21.
Explanation

Azure App Service regional VNet integration requires an unused, dedicated subnet in the same region as the app, with at least a /28 address range. Subnet11 contains VM1, so it cannot be used. Subnet12 is an empty /27 in East US, matching WebApp2's region and providing sufficient addresses for the planned scale-out. Subnet21 is in West US and already hosts an integrated web app, so it cannot be used.
