Actual exam question from Microsoft's DP-300
Question #: 50
Topic #: 6
[All DP-300 Questions]

You have an Azure subscription that contains two instances of SQL Server on Azure Virtual Machines named VM1 and VM2. Both instances run Microsoft SQL Server 2019 CU8.

You need to deploy a failover cluster instance (FCI) to VM1 and VM2. The solution must eliminate the need for the following:

• A distributed network name (DNN)
• A load balancer

What should you do?

  • A. Deploy VM1 and VM2 to a single proximity placement group.
  • B. Deploy VM1 and VM2 to different proximity placement groups in the same Azure region.
  • C. Connect VM1 and VM2 to a single subnet.
  • D. Connect VM1 and VM2 to different subnets on a single virtual network.

Multiple subnets eliminate the need for DNN and load balancer: https://learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/availability-group-overview?view=azuresql-vm#connectivity

C - Connect VM1 and VM2 to a single subnet - meets the requirements - why not D ? - Connect VM1 and VM2 to different subnets on a single virtual network: When using different subnets, a load balancer and/or DNN would still be required for failover redirection, which contradicts the goal of eliminating these components.

Selected Answer: D
The answer is D: Connectivity To match the on-premises experience for connecting to your availability group listener, deploy your SQL Server VMs to multiple subnets within the same virtual network. Having multiple subnets negates the need for the extra dependency on an Azure Load Balancer, or a distributed network name (DNN) to route your traffic to your listener. https://learn.microsoft.com/en-us/azure/azure-sql/virtual-machines/windows/availability-group-overview?view=azuresql

Selected Answer: C
Answer is C: Connect VM1 and VM2 to a single subnet. By connecting both VM1 and VM2 to the same subnet within an Azure virtual network, you can create an FCI without relying on a DNN or load balancer. D. Connect VM1 and VM2 to different subnets on a single virtual network - doesn’t eliminate the need for a DNN or load balancer. Having different subnets doesn’t directly address the requirement.
