An administrator wishes to send traffic from a vNetwork Distributed Switch to a collector virtual machine for analysis. vSphere 5 has been deployed in the datacenter.
Which two configurations will enable the functionality? (Choose two)
A.
The source and target virtual machines must be on the same vNetwork Switch.
B.
The source and target virtual machines must both be on a vNetwork Distributed Switch, but can be on any vDS in the datacenter.
C.
The port group on the distributed port must have Promiscuous Mode enabled.
D.
The port group on distributed port must have NetFlow enabled.
Explanation:
Ref: Page 70 from vsphere-esxi-vcenter-server-50-networking-guide.pdf
There is no relevant information on page 70 of the networking guide.
This one is a better explanation IMO

The point is, B and D are correct
See here’s whats killing me. The question says “An administrator wishes to send TRAFFIC to a collector virtual machine for analysis”
NOT “stats about the traffic” but the TRAFFIC itself. That means he wants to port span. NetFlow will do nothing for you.
