Question
You have a single availability set that contains two SQL Server on Azure Virtual Machines instances. The instances were deployed by using an Azure Marketplace SQL Server 2019 Enterprise image that has the latest cumulative updates applied. The instances are configured as the nodes of a failover cluster instance (FCI) named FCI1. You need to ensure that client applications can connect to FCI1. The solution must meet the following requirements: - Provide an availability SLA. - Minimize costs. What should you create?

- Ba virtual network name (VNN) resource
- Ca Basic Azure Load Balancer
- Da distributed network name (DNN) resource

Explanation
You should create a distributed network name (DNN) resource 1. On Azure Virtual Machines, the DNN routes traffic to the appropriate clustered resource. It provides an easier way to connect to the SQL Server failover cluster instance (FCI) than the virtual network name (VNN), without the need for an Azure Load Balancer 1.
