LAN Topologies Archie Ben IT/240 Justin Davison Aug 28, 2011 11. Your network consists of four servers. Each server has three NICs. Server A is connected to servers B, C, and D. Server B is attached to C and D. Server C is attached to server D. No hub is used. All cabling is CAT 3 UTP crossover cables. What is your physical topology? a. Star b. Bus c. Ring d. Mesh Answer: This would be an example of a modified “mesh” topology. No hub is used, just crossover cables and multiple Nic cards in each server.

A B C D 12. Your network consists of a 24-port bridge, two servers, and 15 workstations. Each computer interfaces with the bridge using its own segment of CAT 5 twisted-pair cable, which is terminated at both ends with RJ-45 connectors. What type of physical topology do you have? a. Mesh b. Bus c. Ring d. Star

Answer: This is an example of the “Star” topology, although the only cabling type that has to be terminated is 10Base2, the terminating of CAT5 cables seems misleading for this description. 13. Your network’s physical topology is that of a star configuration. From time to time, each workstation will hold a packet called a token, during which time it will transmit data and then pass the token along to the next workstation. What is the logical topology of your network? a. Bus b. Star c. Mesh d. Ring This network is a “Star” topology but it’s logical topology is a “Ring”, also known as a token ring.
