This document contains a test paper with multiple choice questions about networking topics like Ethernet, bridges, routers, switches, topologies, and more. It has 8 multiple choice questions with 4 options each and 1 fill in the blanks question with 10 parts. The questions cover topics like Ethernet bandwidth in the early 1980s, devices used to extend LANs, when NFS was introduced, properties of ATM networking, different network topologies, and components of network backbones.
