Question

Hotspot Question You have an Azure subscription that contains the virtual networks shown in the following table. The subscription contains the subnets shown in the following table. You plan to create an Azure web app named WebApp2 that will have the following configurations: - Region: East US - VNet integration: Enabled - Scale out: Autoscale to up to 10 instances For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point. Answer:

Answer Area

  • WebApp2 can be integrated with Subnet11.No
  • WebApp2 can be integrated with Subnet12.Yes
  • WebApp2 can be integrated with Subnet21.No

Explanation

WebApp2 can only integrate with Subnet12 because VNet integration requires the subnet to be in the same region as the web app (East US), and the subnet must be delegated to 'Microsoft.Web/serverFarms' and have enough available IP addresses to support autoscaling. With autoscale up to 10 instances, the subnet needs at least 11+ IP addresses available (instances + 1). Subnet11 fails because it is too small (likely a /29 or smaller with insufficient IPs for 10 instances), and Subnet21 fails because it belongs to a VNet in a different region (not East US), which is a hard requirement for regional VNet integration. Subnet12 meets both the regional requirement and has a sufficient address space to support the planned scale.
