This document contains 10 multiple choice questions about computer networks and networking concepts. The questions cover topics like Ethernet configurations, the MAC sublayer, protocols like ALOHA and CSMA/CD, uses of switches, error control methods, Ethernet cable topologies, MAC address lengths, Ethernet frame padding, and sliding window acknowledgement techniques. The correct answer is provided for each multiple choice question.
