C. A fabric interconnect port in Ethernet switching mode appears to the uplink switch as a host with many MAC addresses.
D. Server-to-server traffic on a common VLAN are locally switched by the fabric interconnect and not the northbound switches.
E. A MAC forwarding table is not used to forward traffic to the uplink switch.
F. A MAC address forwarding table is maintained for server-to-server communications across VLANs.
