   A network architect is designing a high-availability data center fabric. They are considering using UFD on the ToR switches. The architect is concerned about a scenario where a ToR switch loses one of its two uplinks, but the other uplink remains operational. The architect wants to ensure that this partial failure does not cause unnecessary server failover. How does UFD handle this scenario?

   • AUFD disables only the downstream ports that are in the same VLAN as the failed uplink.
   • BUFD keeps the downstream ports enabled because the switch still has a valid path to the core.
   • CUFD sends a notification to the network management system but does not disable any ports.
   • DUFD disables the downstream ports because any uplink failure is considered a critical event.

   An engineer is configuring UFD on a Dell PowerSwitch and has created an uplink-state group. They have assigned two ports as upstream and four ports as downstream. After a test where they shut down both upstream ports, the downstream ports were correctly disabled. However, after bringing the upstream ports back up, the downstream ports remain disabled. What is the most likely reason for this?

   • AThe switch needs to be rebooted for the UFD configuration to take effect.
   • BThe downstream ports need to be manually re-enabled or the uplink-state group needs to be re-enabled.
   • CThe downstream ports are not in the same uplink-state group as the upstream ports.
   • DThe upstream ports are not configured with the correct VLAN.

   What happens to downstream ports when an uplink failure is detected by UFD?

   • AThey are placed in a blocked state but still forward control traffic
   • BThey are automatically reconfigured to use a backup uplink
   • CThey continue to forward traffic but with a warning logged
   • DThey are automatically disabled to prevent traffic from being sent to the failed uplink
