   A network team is evaluating UFD for their data center ToR switches. Their primary concern is preventing traffic black-holing when a ToR switch loses its uplink connectivity. They are comparing UFD to simply relying on the servers' NIC teaming to detect the loss of the default gateway. What is the key advantage of using UFD in this scenario?

   • AUFD proactively disables the server-facing ports, causing the server NIC teaming to fail over immediately via link-state detection.
   • BUFD eliminates the need for redundant ToR switches in the data center design.
   • CUFD provides faster detection of uplink failure than any NIC teaming heartbeat mechanism.
   • DUFD automatically reroutes traffic to the aggregation layer without any server involvement.

   A network administrator is explaining UFD to a colleague. The colleague asks, 'What problem does UFD actually solve?' The administrator should explain that UFD solves the problem of:

   • AInability to load-balance traffic across multiple uplinks.
   • BTraffic black-holing when a switch loses its uplink connectivity but its downstream links remain up.
   • CSecurity vulnerabilities in the data plane when a switch is compromised.
   • DSlow convergence of spanning tree protocol during a link failure.

   A data center has a pair of ToR switches, TOR-A and TOR-B, each with UFD configured. TOR-A has an uplink-state group with two upstream ports (to aggregation switches) and 24 downstream ports (to servers). TOR-B has a similar configuration. A server is connected to both TOR-A and TOR-B via a dual-port NIC with failover. TOR-A loses both of its upstream links. What is the expected sequence of events?

   • ATOR-A disables its 24 downstream ports, the server's NIC teaming detects the link loss on the TOR-A port and fails over to TOR-B.
   • BTOR-A immediately reroutes traffic to TOR-B via a stacking link.
   • CTOR-B detects the failure on TOR-A and disables its own downstream ports to prevent loops.
   • DThe server's NIC teaming detects the loss of the default gateway and fails over to TOR-B after a timeout.

   In a Dell PowerSwitch deployment, what role does UFD play in a network with redundant links?

   • AIt prevents loops by disabling redundant uplinks when they are not needed
   • BIt balances traffic across multiple uplinks to optimize bandwidth usage
   • CIt ensures that downstream devices are aware of an uplink failure so they can fail over to an alternate path
   • DIt provides a backup uplink that automatically takes over when the primary uplink fails
