How does a Cisco router using tail drop handle congestion when a traffic queue becomes full?

  • The router will remove the packet in the front of the queue, move all other packets forward, and insert the just arrived packet at the end.
  • The router will drop any packet that arrives at the end of the queue.
  • The router will remove the most recent data placed in the queue to make space for an arriving packet.
  • The router will only drop non delay-sensitive data that is close to the end of the queue.

Explanation: Tail drop is also known as packet drop and is used by a router to discard any packet that arrives at the tail end of a queue. Tail drop treats all traffic equally and does not differentiate between delay-sensitive data and other traffic.
