On a Cisco Nexus 7000 Series Switch, what is the purpose of this command?
switch# config terminal
switch(config)# mac address-table learning-mode conversational vlan 1-10
switch(config)#
A.
Enable conversational learning on FabricPath vlans 1-10 for F-Series module
B.
Enable FabricPath protocol on VLANs 1–10
C.
No need for this command as conversational learning is enabled by default for all VLANs.
D.
Enable conversational learning on Classical Ethernet VLAN for F-Series module
Explanation:
Seems both answers A and D are correct. However, we cannot chose 2. I think it is A:
“Enable conversational learning on FabricPath vlans 1-10 for F-Series module”
As the command in questions clearly states the vlans IDs.
Am I right?

0
I vote for D.
BEFORE YOU BEGIN
…
Ensure that you are working with CE VLANs.
mac address-table learning-mode conversational vlan vlan-id – Configures the specified CE VLAN(s) on F Series modules for conversational MAC learning. Enter the no form of the command to return to traditional (or non-conversational learning) MAC learning mode. The default MAC learning mode for CE VLANs is traditional. Note: You cannot configure FP VLANs for the traditional MAC address learning mode.
