In NSX-T, which service is used to provide visibility and monitoring of network traffic?

The choice of Flow Monitoring as the correct answer is rooted in its specific function within NSX-T, which is primarily to provide deep visibility into network traffic patterns. Flow Monitoring allows administrators to analyze and visualize traffic flows between different network segments and virtual machines. It captures and monitors the data packets being transmitted, offering insights into the connection states, protocols in use, and the amount of data being transferred.

This visibility is crucial for several operational tasks, including troubleshooting network issues, optimizing network resources, and enhancing security postures by helping to identify unusual traffic patterns or potential threats. Flow Monitoring serves as an essential tool within NSX-T for understanding how network resources are being utilized and how they interact with one another in real-time.

Other alternatives, though they may offer various monitoring capabilities, do not directly focus on the specific traffic flow visibility that Flow Monitoring provides, which is why Flow Monitoring stands out as the most accurate service that meets the question's criteria.
