Sorry I meant B

Would go for D.
ERSPAN encapsulates the packets and allows it to transfer over layer 3. so this is used when you want to remotely monitor a port. i think this also needs to be configured on the physical switch…

Confirmed, the right answer is D as it is stated here https://blogs.vmware.com/vsphere/2011/08/vsphere-5-new-networking-features-port-mirroring.html
“choose a VLAN to encapsulate these mirrored packets by selecting the Encapsulations VLAN box.”

Got some further informations on this site since I wasn’t sure about my previous post: http://www.routereflector.com/2014/07/port-mirroring-on-vmware-vswitchdvswitch-dvmirror/
It seems that the feature is ERSPAN and the VLAN ID is simply used to move the generated mirrored traffic packets over the network.
I would choose B then.

Confirmed B (just finished the exam with flying colors)
In regards of answer D, VLAN is a necessity for Port mirroring, not a feature

Hi Vullis,
Did the exam match up to questions asked in this forum? Just trying to work out study plan.

VDS also supports ERSPAN capability where you will not require any configuration changes on the physical switches. You just need the IP address of the destination virtual machine or analyzer. Just select the “Encapsulated Remote Mirroring (L3) source” option for the session type and walk step-by-step through the wizard. For the source select the ports you want to monitor and for the destination enter the IP address of the virtual machine or analyzer.
