You have servers that run Windows Server 2022 as shown in the following table.
Server2 contains a .NET app named App1.
You need to establish a WebSocket connection from App1 to the SQL Server instance on Server1. The solution must meet the following requirements:
• Minimize the number of network ports that must be open on the on-premises network firewall.
• Minimize administrative effort.
What should you create first?
To establish a WebSocket connection from App1 to the SQL Server instance on Server1 while minimizing the number of open network ports and administrative effort, the best initial step is to create an Azure Relay namespace. Azure Relay provides a way to securely expose an on-premises service, such as an SQL Server, through a hybrid connection. By creating the namespace first, you can then set up the hybrid connection under this namespace, thus meeting the listed requirements efficiently.
Should this be A. Azure Relay ?
As it is on the recent study guide I would also prefer to say Azure Relay.

https://learn.microsoft.com/en-us/azure/azure-relay/relay-what-is-it Hybrid Connections The Hybrid Connections feature in >>Azure Relay<< is a secure, and open-protocol evolution of the Relay features that existed earlier. You can use it on any platform and in any language. Hybrid Connections feature in Azure Relay is based on HTTP and WebSockets protocols. It allows you to send requests and receive responses over web sockets or HTTP(S). This feature is compatible with WebSocket API in common web browsers.

Create a Relay namespace by using the Azure portal. 2. Create a hybrid connection in that namespace by using the Azure portal. 3. Write a server (listener) console application to receive messages. 4. Write a client (sender) console application to send messages. Run applications.
