Statement 1: Yes. An Azure Private Link service exposes a service that is running behind a Standard Load Balancer. Traffic sent to the Private Link service is directed to the frontend IP of the load balancer, which then distributes it to the virtual machines in its backend pool. As shown in the exhibits, privatelinkservice1 is associated with the load balancer lb1, so the resources providing the service must be in backendpool1.

Statement 2: No. The IP address 10.3.0.7 is the Network Address Translation (NAT) IP address within the service provider's virtual network (Subscription1). Users in the consumer's network (Subscription2) will connect to the service by using the private IP address assigned to the private endpoint within their own virtual network (vnet5), not the NAT IP in the provider's network.

Statement 3: Yes. The exhibit showing the private endpoint connections for privatelinkservice1 clearly displays the Connection State as Pending. This state indicates that a consumer in Subscription2 has requested a connection, and it must be explicitly approved by an administrator with permissions on the Private Link service in Subscription1 before the connection becomes active and traffic can flow.

Azure Private Link Service Concepts: According to the official Microsoft documentation, "A Private Link service is mapped to the frontend IP address of a Standard Load Balancer. All the virtual machines in the back-end pool of the Standard Load Balancer serve the traffic of the Private Link service." This validates the first statement. (Source: Microsoft Docs, "What is Azure Private Link service?", Service provider section).

Private Endpoint Connection Workflow: The documentation on managing private endpoint connections states that a connection can be in a "Pending" state, which means "The connection is created manually by the user and is pending approval from the Private Link resource owner." This confirms the third statement, as the owner is in Subscription1. (Source: Microsoft Docs, "Manage a private endpoint connection," Review and approve a private endpoint connection from a service provider section).

Source Network Address Translation (SNAT): For traffic from the private endpoint, the service provider sees the source IP address as a NAT IP allocated from the provider's virtual network. The consumer side uses the private endpoint's IP to connect. This confirms that users in Subscription2 would not use the NAT IP 10.3.0.7.
