   An organization is deploying UFD on a pair of switches that are not in a VLT pair. Each switch has multiple uplinks to different core switches. The requirement is that if ALL uplinks on a switch fail, the downlink ports should be disabled. However, if only one uplink fails, the downlinks should remain active. How should the uplinks be configured in UFD?

   • APlace each uplink in a separate UFD group, each with its own set of downlinks.
   • BConfigure UFD to disable downlinks when any uplink fails by using the 'any' keyword.
   • CPlace all uplinks in a single UFD group so that the downlinks are disabled only when all uplinks in that group fail.
   • DUFD cannot be configured to disable downlinks only when all uplinks fail; it always disables on any single uplink failure.
