Scenario Recap: * Goal: Ensure app1 (on VM1 in vnet1) can connect to service1 (Azure Cognitive Search) without routing over the public internet. * Proposed Solution: Deploy service1 with a public endpoint, and configure an IP firewall rule. Analysis: * IP firewall rules restrict which public IPs can access a service. * However, traffic still routes over the public internet. The firewall only filters access, it does not provide private connectivity. * To avoid internet traffic, you must use Private Link (private endpoint). The answer: B. No Reference: Secure access to Cognitive Search with Private Link
