What happens when the memory queue of a device fills up and new network traffic is received?

• The network device sends the received traffic immediately.
• The network device will drop the arriving packets.
• The network device drops all traffic in the queue.
• The network device queues the received traffic while sending previously received traffic.

Explanation: Packets received by a network device experiencing congestion cannot be transmitted until previous packets have been processed. If the queue is full, the network device will begin to drop packets as new traffic arrives.
