Which advanced feature would you recommend for a Windows administrator who wants to monitor network traffic of a virtual machine?

Port Mirroring is the most suitable advanced feature for a Windows administrator aiming to monitor the network traffic of a virtual machine. This technique enables the duplication of the traffic from one or more network ports, allowing the administrator to analyze the captured data without interrupting the original network communications.

By setting up port mirroring, the administrator can effectively observe the traffic flowing to and from a specific virtual machine. This setup is particularly valuable for troubleshooting, performance monitoring, and ensuring security, as it provides visibility into the virtual network interactions in real-time. Port mirroring can be leveraged using tools like Wireshark or other network analyzers, allowing for detailed inspection of the packets exchanged over the network.

While the other options offer valuable networking features, they do not specifically focus on traffic monitoring. NIC Teaming, for instance, is primarily used for improving network reliability and bandwidth by combining multiple network interfaces, rather than for examining traffic. Traffic Shaping manages the flow of data to ensure proper bandwidth allocation, but does not provide the interception of traffic for monitoring purposes. Network Isolation restricts network access for certain virtual machines, which does not facilitate traffic analysis.
