Which two configurations will enable this functionality?

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 this functionality? (Choose two.)

A.
The source and target virtual machines must both be on the same vNetwork Distributed 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 or distributed port must have Promiscuous Mode enabled.

D.
The port group or distributed port must have NetFlow enabled.

    on Q.726 the correct answer is B and D and the explanation reporter is this one:
    Explanation:

    Page 72 from vsphere-esxi-vcenter-server-50-networking-guide.pdf

    Configure NetFlow Settings
    NetFlow is a network analysis tool that you can use to monitor network monitoring and virtual machine traffic.
    NetFlow is available on vSphere distributed switch version 5.0.0 and later.

    With an IP address to the vSphere distributed switch, the NetFlow collector can interact with the vSphere distributed switch as a single switch, rather than interacting with a separate, unrelated switch for each associated host.

    SO base on this explanation I think that correct answer is B and D.

  2. Bala says:

    As per the above article A and D were correct, because it is clearly stating that it will consider each vds as a single switch, if you have multiple vDS then it is nothing but multiple switches.

    Uh NetFlow has NOTHING to do w/ port spanning traffic. A and C are the correct answers; you’re trying to aggregate all VM traffic to one machine for analysis. NetFlow will only give you information -about- the traffic, but wont span the traffic for you.

  4. CiscoJedi says:

    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.
