C is indeed correct. "Use Traceflow to inspect the path of a packet. Traceflow traces the transport node-level path of a packet. The trace packet traverses the logical switch overlay, but is not visible to interfaces attached to the logical switch. In other words, no packet is actually delivered to the test packet’s intended recipients.

Yes, C is right. Traceflow adds functionality to NSX that provides assistance with the Operations of the NSX Network Virtualization platform. Traceflow allows the injection of varying types of packets into application topologies. As the name suggests traces the flow through the path. It collects observation of actions, hosts, relevant components, and their names. This is used to help administrators visualize a topology path. As this uses Synthetic traffic, it is non distributed and allows an administrator to test the network and security of an application from one VM all the way to another VM. https://docs.hol.vmware.com/HOL-2018/hol-1892-01-chg_html_en/ https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/nsx/vmware-operational-transformation-with-nsx.pdf (see page 11, Debugging with Traceflow)

D is not the answer because it's not limited to ICMP. You can set it up to TCP and UDP for example

because you it's not limited to ICMP and you can use other types of traffic, also check the below : As this uses Synthetic traffic, it is non distributed and allows an administrator to test the network and security of an application from one VM all the way to another VM. https://docs.hol.vmware.com/HOL-2018/hol-1892-01-chg_html_en/
