[All AZ-700 Questions]

HOTSPOT -
You are planning an Azure solution that will contain the following types of resources in a single Azure region:
✑ Virtual machine
✑ Azure App Service
✑ Virtual Network gateway
✑ Azure SQL Managed Instance
App Service and SQL Managed Instance will be delegated to create resources in virtual networks.
You need to identify how many virtual networks and subnets are required for the solution. The solution must minimize costs to transfer data between virtual networks.
What should you identify? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Question was on exam 11/2021 I believe the answer to be 1 and 4. Web page given in answer, and below states App Service Environment requires a dedicated subnet. https://docs.microsoft.com/en-us/azure/virtual-network/virtual-network-for-azure-services#services-that-can-be-deployed-into-a-virtual-network

Correct answer is 1 Vnet. 3 Subnets are needed. Gateway subnet for VPN Gateway. Default subnet for VM Dedicated subnet for SQL Managed instance. https://azure.microsoft.com/en-gb/resources/templates/sql-managed-instance-azure-environment/ No subnet is needed for App Service. Build it and dont just believe the answers written here as many answers are wrong.

Yes, you need a dedicated subnet for Azure App Service if you want to integrate your app with an Azure virtual network. The subnet must be allocated an IPv4 /28 block (16 addresses). We recommend that you have a minimum of 64 addresses (IPv4 /26 block) to allow for maximum horizontal scale. If you don't integrate your app with an Azure virtual network, you don't need a dedicated subnet. However, your app will be exposed to the public internet, which may not be desirable for some applications. Here are the subnet requirements for Azure App Service Environment: The subnet must be empty. The subnet must be delegated to Microsoft. Web/hostingEnvironments. The size of the subnet should be at least /26 (64 addresses). If you are using Windows Containers, you will need to allocate an additional IP address per app for each App Service plan instance. This means that if you have 10 Windows Container App Service plan instances with 4 apps running, you will need 50 IP addresses and additional addresses to support horizontal (up/down) scale.

Virtual Network: All resources can share a single virtual network to minimize costs. Subnets: Subnet 1: For the Virtual Machine. Subnet 2: For the Azure App Service (delegated for App Service resources). Subnet 3: For the Virtual Network Gateway (GatewaySubnet). Subnet 4: For the Azure SQL Managed Instance (delegated for SQL resources).

The solution must minimize costs to transfer data between virtual networks. Meaning App service Gateway-required virtual network integration is not an option. The regional virtual network integration feature enables you to place the back end of your app in a subnet in a Resource Manager virtual network in the same region as your app. This feature isn't available from an App Service Environment, which is already in a virtual network. https://learn.microsoft.com/en-us/azure/app-service/networking-features 4 it is

Correct is 4. 2 subnets for the VPN gateway, the app service and vm can be on the same one, and Azure SQL Managed Instance must be deployed within an Azure virtual network and the subnet dedicated for managed instances only.

I believe the given answer is correct, my reasoning for this is as follows. 1. Azure SQL Managed Instance requires its own subnet. 2. A Virtual Network Gateway requires its own subnet. 3. An app service by default does not connect to a virtual network and is accessible by its public frontend. It is my understanding that if you want an app service to integrate with a virtual network you need to enable VNET integration, which requires its own subnet. 4. The VM can share subnets, however in this question there are 4 resources and three of them require their own subnet, meaning the VM will require its own subnet in this instance.
