How does a Cisco Unified Computing System react when configured for disjoint Layer 2 domains?

How does a Cisco Unified Computing System react when configured for disjoint Layer 2 domains?

A.
Automatic pinning is disabled; VLAN membership must be statically pinned to the uplink ports.

B.
VLANs must be divided between the fabric interconnects using PIN groups.

C.
The VLAN traffic for a disjoint network can only travel along an uplink that is specifically
assigned to this VLAN and is selectively excluded from all other uplinks.

D.
When you configure disjoint Layer 2 networks, you must assign VLANs to uplink interfaces.

The configuration for disjoint L2 networks works on a principle of selective exclusion. Traffic for a VLAN that is designated as part of a disjoint network can only travel along an uplink Ethernet port or port channel that is specifically assigned to that VLAN, and is selectively excluded from all other uplink ports and port channels. However, traffic for VLANs that are not specifically assigned to an uplink Ethernet port or port channel can still travel on all uplink ports or port channels, including those that carry traffic for the disjoint L2 networks

So the answer looks to be C
