Explanation:
WebApp1 can communicate with VM2. No, this is not correct. According to the tables, WebApp1 is integrated with VNet1, which has a peering connection with VNet2. However, VM2 is in VNet3, which is not peered with VNet1 or VNet2. Therefore, WebApp1 cannot communicate with VM2 across different virtual networks1.
NSG1 controls inbound traffic to WebApp1. No, this is not correct. According to the tables, NSG1 is associated with Subnet1 in VNet1, which is integrated with WebApp1. However, network security groups only control outbound traffic from App Service apps to virtual networks, not inbound traffic to App Service apps from virtual networks2. Therefore, NSG1 does not control inbound traffic to WebApp1.
WebApp2 can communicate with VM1. Yes, this is correct. According to the tables, WebApp2 is integrated with VNet3, which has a peering connection with VNet2. VM1 is in Subnet2 in VNet2, which has a network security group named NSG2 that allows inbound traffic from any source on port 803. Therefore, WebApp2 can communicate with VM1 on port 80 across peered virtual networks.
