Which statement about Cisco FabricPath is true?
A.
It is the best solution for interconnecting multiple data centers.
B.
It optimizes STP throughout the Layer 2 network.
C.
It is a simplified extension of Layer 3 networks across a single data center.
D.
The Cisco FabricPath domain appears as a single STP bridge, where each edge port uses the same
MAC address.
Explanation:
To have a loop-free topology for the CE/FabricPath hybrid network, the FabricPath network
automatically displays as a single bridge to all connected CE devices. The STP domains do not cross
into the FabricPath network. If multiple STP domains are defined, BPDUs and topology change
notifications (TCNs) are localized to the domain. If a connected STP domain is multihomed to the
FabricPath domain, a TCN must be able to reach to all devices in the STP domain through the
FabricPath domain. As a result, the TCN is sent to the FabricPath domain through the IS-IS protocol
data unit (PDU) by default.http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/mkt_ops_guides/513_n1_1
