Correct answer: A private endpoint assigns a private IP from your VNet to the PaaS resource (Azure SQL) and provides network-level isolation; a service endpoint does not assign a private IP and instead allows the subnet's public IP range to access the service over the Microsoft backbone while relying on service-level firewall rules..
Why this is the answer
A private endpoint creates a network interface (NIC) with a private IP address within your VNet, making the PaaS resource (like Azure SQL) appear as if it's directly in your VNet. This provides true network isolation. A service endpoint, conversely, does not assign a private IP to the PaaS resource. Instead, it extends your VNet's identity to the Azure service over the Microsoft backbone, allowing you to configure service-level firewall rules to restrict access to specific subnets. The traffic still flows over the public IP space of the service, but it's routed directly over the optimized Microsoft backbone rather than the public internet.
