Exam DP-300 topic 2 question 18 discussion

Actual exam question from Microsoft's DP-300

Question #: 18
Topic #: 2

You have an Azure virtual machine named VM1 on a virtual network named VNet1. Outbound traffic from VM1 to the internet is blocked.
You have an Azure SQL database named SqlDb1 on a logical server named SqlSrv1.
You need to implement connectivity between VM1 and SqlDb1 to meet the following requirements:
✑ Ensure that VM1 cannot connect to any Azure SQL Server other than SqlSrv1.
✑ Restrict network connectivity to SqlSrv1.
What should you create on VNet1?

A. a VPN gateway
B. a service endpoint
C. a private endpoint
D. an ExpressRoute gateway

Show Suggested Answer

Suggested Answer: C 🗳️
A private endpoint is a network interface that uses a private IP address from your virtual network. This network interface connects you privately and securely to a service powered by Azure Private Link. By enabling a private endpoint, you're bringing the service into your virtual network.
The service could be an Azure service such as:
✑ Azure Storage
✑ Azure Cosmos DB
✑ Azure SQL Database
✑ Your own service using a Private Link Service.

Service Endpoints are targeted at VNets/Subnets. Private Link is targeted at individual entities, in this scenario VM1 to SqlDb1. The question requires that VM1 only be able to connect to SqlDb1. There may be other SQL Databases on SqlSrv1. Answer must be Private Link.

answer is correct. Azure Private Link allows you to access Azure PaaS service over Private IP address within the VNet. It gets a new private IP on your VNet. When you send traffic to PaaS resource, it will always ensure traffic stays within your VNet.

Private Endpoints grant network access to specific resources behind a given service providing granular segmentation. Traffic can reach the service resource from on premises without using public endpoints. A Service Endpoint remains a publicly routable IP address. A Private Endpoint is a private IP in the address space of the virtual network where the private endpoint is configured.

I agree, The key difference between Private Link and Service Endpoints is that with Private Link you are injecting the multi-tenant PaaS resource into your virtual network. ... Unlike Service Endpoints, Private Link allows access from resources on your on-premises network through VPN or ExpressRoute, and from peered networks

I think is the other way around: https://docs.microsoft.com/en-us/azure/private-link/private-link-faq#:~:text=Traffic%20can%20reach%20the%20service,the%20private%20endpoint%20is%20configured.
