Which of the following terms describes this switching architecture?Distributed switchingPort forwardingTraffic shapingNeighbor discoveryFlow control

105 Review the following figure. Note that each store-and-forward switch has three connected node ports and one port for switch-to-switch connections.

111 Each of the following Carrier-Sense Multiple Access with Collision Detection (CSMA/CD) events occurs on an Ethernet network when two stations transmit simultaneously, although not in the order listed. Which of the following events occurs immediately after the collision?The two stations observe a random backoff interval.The two stations transmit a jam signal.The two stations stop transmitting.The two stations listen to see if the channel is idle.The two stations begin retransmitting their frames.

112 For the Carrier-Sense Multiple Access with Collision Detection (CSMA/CD) mechanism to function properly on an Ethernet network, host systems must be able to detect when a collision occurs, so they can react to it. Which of the following cabling errors can prevent the collision detection process from functioning properly?Excessively long cable segmentsIncorrect wiring pinoutsToo many systems on a single networkAn excessive number of collisions

113 When a packet collision between two systems occurs on an Ethernet network, Carrier-Sense Multiple Access with Collision Detection (CSMA/CD) causes the two systems to stop transmitting and generate a jam signal. After sending the jam signal, why do the two systems wait for a randomized backoff interval before retransmitting their packets?They need time to reassemble the packets.To prevent another collision from occurring.They need to rebuffer the packet.To recalculate the packets’ checksum values.
