   An engineer is troubleshooting a UFD issue. The 'show ufd' command shows that UFD is enabled, but the downlink ports are not being disabled when the uplink fails. The engineer has verified that the uplink is physically down. What is the most likely configuration error?

   • AThe uplink needs to be in a different VLT domain.
   • BThe uplink was designated as a downlink and the downlinks as uplinks.
   • CThe downlink ports were not designated as downlinks in the UFD configuration.
   • DUFD is not supported on this platform.

   A data center has a pair of switches in a VLT domain. Each switch has its own set of downlink ports to servers. The uplinks from the VLT pair to the core are also part of the VLT. The network team wants to use UFD to disable downlink ports on a switch if its uplink fails. However, they are concerned about the VLT interconnect. What is the correct approach?

   • AUFD cannot be used with VLT; it is only supported on standalone switches.
   • BConfigure UFD on each switch independently, designating the VLT uplinks as uplinks and the local downlinks as downlinks.
   • CConfigure UFD only on the primary VLT switch, as it controls the VLT domain.
   • DConfigure the VLT interconnect as an uplink in UFD, so that if it fails, the downlinks are disabled.

   A network architect is considering UFD for a data center design. The primary goal is to prevent black-holing of traffic when an uplink fails. Which statement accurately describes the primary purpose of UFD in this context?

   • AUFD monitors the health of downlink ports and disables them if they are faulty.
   • BUFD increases bandwidth by aggregating multiple uplinks into a single logical link.
   • CUFD disables downlink ports when the uplink fails, forcing connected devices to use an alternate path.
   • DUFD provides a redundant uplink path by automatically failing over to a backup link.

   A switch has UFD configured with a single uplink and multiple downlinks. The engineer wants to verify that the downlinks are in the 'up' state and that UFD is ready to react to an uplink failure. Which command output would show the UFD status and the state of the downlink ports?

   • Ashow interfaces description
   • Bshow ip route
   • Cshow ufd
   • Dshow mac address-table

   An engineer is troubleshooting a UFD issue. The 'show ufd' command shows that UFD is enabled, and the uplink is down. However, the downlink ports are still in the 'up' state. The engineer has verified that the downlink ports are correctly designated as downlinks. What is the most likely cause of this issue?

   • AThe uplink is a port-channel and UFD does not support port-channels.
   • BThe downlink ports are in a different VLAN than the uplink.
   • CThe uplink is not in the same UFD group as the downlinks.
   • DThe switch needs to be rebooted for UFD to take effect.
