   A data center architect is designing a top-of-rack (ToR) switch deployment where servers connect to the ToR via two 10GbE links, and the ToR connects upstream to two aggregation switches. The architect wants to ensure that if both upstream links on the ToR fail, the server-facing ports are automatically disabled so the servers' NIC teaming software immediately fails over to the secondary ToR switch. Which UFD component configuration is essential for this behavior?

   • AAssign the two upstream ports to the downstream port list and the server-facing ports to the upstream port list of the same uplink-state group.
   • BCreate two separate uplink-state groups, one for each server-facing port, and assign both upstream ports to each group's upstream list.
   • CConfigure the two server-facing ports as uplink ports and the two upstream ports as downstream ports in a single uplink-state group.
   • DAssign the two server-facing ports to the downstream port list of an uplink-state group, and the two upstream ports to the upstream port list of the same group.

   A Dell PowerSwitch ToR switch has UFD configured with an uplink-state group. The upstream ports are connected to two different aggregation switches. One aggregation switch is rebooted for maintenance, causing both links to that switch to go down. The other aggregation switch's links remain up. What happens to the downstream ports in the UFD group?

   • AThey are disabled and then re-enabled after a 30-second timer.
   • BThey are disabled only if the remaining aggregation switch also fails.
   • CThey are disabled because UFD considers the uplink path degraded.
   • DThey remain enabled because at least one upstream port is still operational.

   What is the function of the uplink-state group in UFD?

   • AIt defines the relationship between upstream and downstream ports so that a failure in the upstream group disables the downstream ports
   • BIt monitors the status of downstream ports and reports to the network management system
   • CIt aggregates multiple uplinks into a single logical link for higher bandwidth
   • DIt provides a backup path for traffic when an uplink fails

   A data center architect is designing a leaf-spine fabric. Each leaf switch has multiple 100GbE uplinks to the spine layer and connects to servers via 25GbE links. The architect wants to use UFD to ensure that if a leaf switch loses all connectivity to the spine layer, the server-facing ports are disabled to trigger server NIC teaming failover. What is the primary purpose of this UFD configuration?

   • ATo automatically reroute traffic from the failed leaf switch to a redundant leaf switch.
   • BTo provide a fast, deterministic link-down signal to the servers so they can fail over to a redundant leaf switch.
   • CTo reduce the amount of traffic sent to the spine layer during a failure.
   • DTo prevent the leaf switch from forwarding traffic to the spine layer when the uplinks are down.

   A network architect is comparing UFD to other high-availability mechanisms for a data center ToR deployment. The architect's primary goal is to ensure that servers can fail over to a redundant ToR switch as quickly as possible when the primary ToR loses its uplink connectivity. Which mechanism provides the fastest and most deterministic failover trigger for the servers?

   • AConfiguring static routes on the servers to the redundant ToR as a backup.
   • BUFD, which disables the server-facing ports on the primary ToR, causing the server NIC teaming to detect a link-down event.
   • CRelying on the server's NIC teaming to detect the loss of the default gateway via periodic heartbeat probes.
   • DUsing Spanning Tree Protocol (STP) to reroute traffic from the primary ToR to the redundant ToR.
