Use vlan have a lot of limitation, ERSPAN is industrial standard and vsphere 5 already supported
It is a feature of vds
I am 100% sure you can get marks if your answer b
port mirroring based on source port – Vlan is destination, so ERSPAN should be the good one
D should be correct. ERSPAN is not vmware feature.
It seems that VLAN is required for port mirroring
