You have an Azure virtual machine named VM1 that has the Web Server (IIS) server role installed. VM1 hosts a critical line-of-business (LOB) application.
After the security team at your company deploys a new security baseline to VM1, users begin reporting that the application is unresponsive.
You suspect that the security baseline has caused networking issues.
You need to perform a network trace on VM1.
What should you do?

https://docs.microsoft.com/en-us/troubleshoot/azure/virtual-machines/performance-diagnosticsThe correct answer to the given question is:
C. From the Azure portal, configure the Diagnostics settings for VM1.
Explanation:
When users report that a line-of-business (LOB) application is unresponsive after a new security baseline is deployed on an Azure virtual machine (VM), it could be due to networking issues. In such a scenario, performing a network trace on the VM is necessary to identify the root cause of the problem.
Option A, which is to run netstat from VM1, is incorrect because netstat is a command-line tool that provides information about active connections and network statistics. While netstat can be used to troubleshoot network issues on the VM, it does not perform a network trace.
Option B, which is to create a Data Collector Set from Performance Monitor on VM1, is incorrect because it is a performance monitoring tool that collects performance data such as CPU usage, memory usage, and disk usage. It does not perform a network trace.
Option D, which is to configure the Performance diagnostics settings for VM1, is incorrect because Performance diagnostics is a monitoring tool that collects performance metrics, such as CPU usage, disk usage, and memory usage. It does not perform a network trace.
Option C is the correct answer because it involves configuring the Diagnostics settings for VM1 from the Azure portal. Diagnostics settings provide a way to collect diagnostics data, such as logs and metrics, from a VM. By configuring diagnostics settings for a VM, you can collect network traffic data, which can be used to perform a network trace. Once the diagnostics data is collected, it can be analyzed using network analysis tools to identify the root cause of the networking issue.
In conclusion, the correct option to perform a network trace on an Azure virtual machine with networking issues is to configure the Diagnostics settings for the VM in the Azure portal.
