Final answer:
Late collisions would be observed only on the half-duplex end of the connection in this scenario.
Step-by-step explanation:
When one end of an Ethernet connection is configured for full duplex and the other end is configured for half duplex, late collisions would be observed only on the half-duplex end of the connection. Late collisions occur when a device transmits data onto the network while another device is already transmitting, causing a collision. In half duplex mode, collision detection is used, but in full duplex mode, each end of the connection can transmit and receive data simultaneously, eliminating the possibility of collisions.
