Exam AZ-700 topic 5 question 39 discussion

100% A. https://learn.microsoft.com/en-us/azure/private-link/disable-private-endpoint-network-policy?tabs=network-policy-portal

Enabling delegation on Subnet1 allows you to assign the subnet to specific Azure services, such as Azure Private Link. This is necessary for configuring user-defined routes for private endpoints

Delegation! When creating a private endpoint, Azure needs to control traffic routing between the endpoint and the Azure Private Link service. To do this, the subnet where the private endpoint resides must be delegated to the appropriate Azure service (e.g., Private Link).

Delegation Can't be used with a private endpoint if the subnet is delegated. https://learn.microsoft.com/en-us/azure/virtual-network/subnet-delegation-overview#effect-of-subnet-delegation-on-your-subnet It's A Enable Network Policy, By default, network policies are disabled for a subnet in a virtual network. To use network policies like user-defined routes and network security group support, network policy support must be enabled for the subnet, This setting only applies to private endpoints in the subnet and affects all private endpoints in the subnet https://learn.microsoft.com/en-us/azure/private-link/disable-private-endpoint-network-policy?tabs=network-policy-portal

Considering Question statement what you do in subnet1 would be enabling delegation to ensure that traffic to and from the private endpoint is correctly routed to the Azure Private Link service

Sorry! Amending! https://learn.microsoft.com/en-us/azure/private-link/private-link-faq#can-i-use-for-user-defined-routes-only--network-security-groups-only--or-for-both-for-private-endpoint- Can I use for User-Defined Routes only, Network Security Groups only, or for both for Private EndPoint? Yes. To utilize policies like User-Defined Routes and Network Security Groups, you need to* enable Network policies for a subnet in a virtual network for the Private Endpoint*. This setting affects all the private endpoints within the subnet.

To route traffic between the private endpoint and the Azure Private Link service using a user-defined route, you should Enable delegation on Subnet1. So, the correct answer is: B. Enable delegation. Delegation on a subnet is necessary for private endpoints to communicate with Azure Private Link services, as it allows the necessary configuration and management of private endpoints within that subnet.
