C :Note: Assigning VLAN 4094 and port channel X to the mlagpeer trunk group prevents traffic from VLAN 4094 from being carried on any other trunk.

The trunk group MLAG-Peer command creates a trunk group, which is a cool way of assigning VLANs to trunks. We now need to assign the same group to the peer-link: Arista-1(config-vlan-4094)#int po 1 Arista-1(config-if-Po1)#switchport trunk group MLAG-Peer Now, VLAN 4094 will only be included on trunks that are also assigned to the MLAG- Peer trunk group. By doing this, when we create a new trunk, by default VLAN 4094 will not be included. In arista worrior

By doing this, when we create a new trunk, by default VLAN 4094 will not be included. This keeps the MLAG peer-link traffic on this link, and only on this link (unless you add the MLAG-Peer trunk group to another trunk, but don’t do that). Maybe C is correct.
