Which feature in NSX-T provides visibility into network paths and impacts?

The feature that provides visibility into network paths and their impacts in NSX-T is Traceflow. This tool allows users to visualize the flow of packets across the virtual network, enabling them to understand how traffic is processed through various components such as routers, firewalls, and other network services. By simulating a packet's journey through the network, Traceflow helps in diagnosing issues related to connectivity and performance, providing critical insights into how different segments of the network interact with each other.

Using Traceflow, network administrators can identify bottlenecks, misconfigurations, and other factors that might impede optimal performance. The ability to see where packets go and how they encounter various network elements is essential for troubleshooting and optimizing virtual network configurations. This visibility is particularly valuable in complex environments where multiple services and security policies intersect.

The other options, while they may offer useful functionality within NSX-T, do not focus specifically on providing insights into network paths and their impacts in the same holistic manner as Traceflow.
