VMware NSX 4.x Professional (2024) — Question 36

How does the Traceflow tool identify issues in a network?

Answer options

• A. Compares intended network state in the control plane with Tunnel End Point (TEP) keepalives in the data plane.
• B. Compares the management plane configuration states containing control plane traffic and error reporting from transport node agents.
• C. Injects ICMP traffic into the data plane and observes the results in the control plane.
• D. Injects synthetic traffic into the data plane and observes the results in the control plane.

Correct answer: D

Explanation

The correct answer is D because Traceflow works by injecting synthetic traffic into the data plane to track its path and assess where issues may arise. Options A and B focus on comparing states or configurations rather than directly testing traffic flow, while option C involves ICMP traffic instead of synthetic traffic, which is not the method used by Traceflow.
