   A switch has UFD configured with two uplinks and four downlinks. Both uplinks fail. What is the expected behavior of the downlink ports?

   • AThe downlink ports remain up because UFD only reacts to a single uplink failure.
   • BOnly half of the downlink ports are disabled, one for each failed uplink.
   • CAll downlink ports are disabled because all uplinks in the group have failed.
   • DThe downlink ports are disabled and then automatically re-enabled after a timer.

   A network team is planning to deploy UFD in a data center. They have a mix of servers with dual NICs connected to two different switches. The goal is to ensure that if a switch loses its uplink, the servers connected to that switch will fail over to the other switch. How does UFD facilitate this failover?

   • AUFD sends a notification to the server to switch to the other NIC.
   • BUFD disables the downlink ports on the affected switch, causing the server's NIC team to detect the link loss and use the other NIC.
   • CUFD reroutes traffic to the other switch through the VLT interconnect.
   • DUFD keeps the downlink ports up but marks them as degraded.

   An engineer is verifying UFD operation after a failure event. The 'show ufd' command shows that the uplink is up, but the downlinks are still disabled. The engineer wants to confirm that the downlinks are disabled due to UFD and not another reason. Which additional command output would help confirm this?

   • Ashow mac address-table
   • Bshow vlt brief
   • Cshow interfaces status | include down
   • Dshow logging | include UFD
