- To enable VM1 to access storage1 by using the Microsoft backbone network, you must enable a service endpoint on the Default subnet.Yes
- You can deploy an App Service Environment to the Default subnet.No
Explanation
NSG1 is associated with the SQL subnet, so any inbound traffic restrictions to SQL1 (which resides in the SQL subnet) must be managed through NSG1's access rules - this is correct because the NSG governs subnet-level traffic filtering. Enabling a service endpoint on the Default subnet (where VM1 resides) allows traffic from VM1 to Azure Storage to traverse the Microsoft backbone network rather than the public internet, which is the correct mechanism for private routing to PaaS services. An App Service Environment (ASE) requires a dedicated subnet with a minimum size of /24 and cannot be deployed to the Default subnet if it is already in use by other resources (VM1) or does not meet the size/delegation requirements; ASE also requires subnet delegation to Microsoft.Web/hostingEnvironments, which conflicts with general-purpose subnet usage.
