What procedure does the instructor use to test DNS towards the end of the demonstration?

The instructor runs nslookup from a command line to verify DNS.
The instructor runs nslookup from Azure CLI to verify DNS.
The instructor runs nslookup from Windows PowerShell to verify DNS.
The instructor uses a graphical interface to check DNS settings.

The correct answer is: The instructor runs nslookup from Azure CLI to verify DNS.

The instructor tests DNS by running nslookup from the Azure CLI, which is essential for administering DNS in a cloud environment like Azure. Using the Azure Command-Line Interface allows the instructor to directly interact with Azure resources and services programmatically. This method is particularly effective in a hybrid setup where DNS resolution is critical for communication between on-premises and cloud resources. By utilizing Azure CLI, the instructor can easily verify whether the DNS records are correctly set up and ensure that they resolve as expected. This approach is beneficial for checking configurations such as custom DNS servers set in Azure or validating public DNS records exposed to the internet. In contrast, while command line tools and PowerShell can also be valuable for testing DNS locally or in other contexts, running the nslookup command specifically in the Azure CLI emphasizes the cloud-based environment's integration and operational management. The use of a graphical interface, although user-friendly, may not provide the same level of flexibility or insight into automated testing and scripting capabilities available through command-line tools in a cloud context.
