Which Cisco Nexus feature is best managed with DCNM-SAN?

A.
VSS

B.
domain parameters

C.
virtual switches

D.
AAA

Explanation:
The Fibre Channel domain (fcdomain) feature performs principal switch selection, domain ID
distribution, FC ID allocation, and fabric reconfiguration functions as described in the FC-SW-2
standards. The domains are configured on a per VSAN basis. If you do not configure a domain ID, the
local switch uses a random ID.
This section describes each fcdomain phase:
• Principal switch selection — This phase guarantees the selection of a unique principal switch
across the fabric.
• Domain ID distribution — This phase guarantees each switch in the fabric obtains a unique
domain ID.
• FC ID allocation — This phase guarantees a unique FC ID assignment to each device attached to
the corresponding switch in the fabric.
• Fabric reconfiguration — This phase guarantees a resynchronization of all switches in the fabric
to ensure they simultaneously restart a new principal switch selection phase.
