   Why does UFD disable downstream ports rather than simply logging the uplink failure?

   • ATo allow the switch to reboot and recover from the failure
   • BTo prevent unauthorized access to the switch
   • CTo conserve power by turning off unused ports
   • DTo immediately signal connected devices that the path is unavailable so they can reroute traffic

   A network engineer is configuring UFD on a Dell PowerSwitch ToR switch. The switch has four upstream ports and 48 downstream ports. The engineer wants to ensure that if the switch loses connectivity to the core, the downstream ports are disabled. However, the engineer is concerned about a scenario where the switch loses one upstream port, but the remaining three are still operational. What is the behavior of UFD in this scenario?

   • AUFD disables the downstream ports and then re-enables them after a 5-second timer.
   • BUFD disables all 48 downstream ports because the uplink path is degraded.
   • CUFD keeps the downstream ports enabled because the switch still has a valid path to the core.
   • DUFD disables only the downstream ports that are in the same VLAN as the failed uplink.

   A network engineer has configured UFD on a Dell PowerSwitch ToR switch with an uplink-state group containing four upstream ports and eight downstream ports. One of the four upstream links fails. What is the immediate effect on the downstream ports in the group?

   • AThe downstream ports are disabled and re-enabled after a 5-second hold-down timer.
   • BThe downstream ports remain enabled because at least one upstream port is still operational.
   • COnly the four downstream ports associated with the failed uplink are disabled.
   • DAll eight downstream ports are disabled because UFD reacts to any single uplink failure.

   What is the primary purpose of Uplink Failure Detection (UFD) on Dell PowerSwitch devices?

   • ATo detect when an uplink fails and automatically disable the corresponding downstream ports to prevent traffic black-holing
   • BTo monitor the health of downstream devices and shut down uplinks if a downstream device fails
   • CTo provide redundant power to the switch in case of a power supply failure
   • DTo automatically reroute traffic to a standby uplink without any disruption
