A Cisco UCS fabric interconnects in end-host mode learns MAC addresses on which port types? (Choose four.)
A. Uplink Ethernet ports or border ports
B. Appliance ports
C. Server ports
D. Fabric ports
E. Backplane ports
F. vEth interfaces
G. A Fabric Interconnect doesn’t learn MAC addresses in End Host mode. Pinning is used instead.
Correct Answer: BCEF
Explanation/Reference:
Explanation:
End-host mode offers these main features:
Spanning Tree Protocol is not run on both the uplink ports
MAC address learning occurs only on the server ports and appliance ports
MAC address aging is not supported; MAC address changes are fully supported
Active-active links are used regardless of the number of uplink switches
The solution is highly scalable because the control plane is not occupied
All uplink ports connect to the same Layer 2 cloud
