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
I believe this to be a mesh mainly because all the servers are connected to one another. There is no hub used and Cat 3 UTP would be the cable for use in a small topology such as this. Also, the Cat 3 UTP cable is used in 80% of all LANs. Concerning the network interface cards (NIC), this allows the server to communicate with any computer on the network.

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

I believe this to be a star topology because each of the 15 work station connects to a central point (which would be the port bridge connected to the servers). The Cat 5 cable handles standard networking. The RJ-45 connectors are in place because they are the norm when networking. Only 2 wires in the connector carry Ethernet signals. One end of the cable is connected to the computer and the other end is connected to the port bridge.

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 would be a ring topology because the token (data packet) will pass it along until it finds the node to which it was addressed.
