1. NICs can tell whether an arriving frame is tagged or not simply by looking at it. How can they do so? (Hint: They look at the value in the two octets following the address fields.
2. You will create a design for a network connecting four buildings in an industrial park. Hand in a picture showing your network. There will be a core switch in each building.
? Building A is the headquarters building.
? Building B is 85 meters south and 90 meters east of the headquarters building.
? Building C is 150 meters south of the headquarters building.
? Building D is 60 meters west of Building C.
? Computers in Building A need to communicate with computers in Building B at 60 Mbps.
? Computers in Building A need to be able to communicate with computers in Building C at 300 Mbps.
? Computers in Building A must communicate with computers in Building D at 50 Mbps.
? Computers in Building C must communicate with computers in Building D at 75 Mbps.
? Building A will connect directly to Buildings B and C.
? Building C will connect directly to Building D.
a) Specify the standard you will use to connect Building A to Building B.
b) Specify the standard you will use to connect Building A to Building C.
c) Specify the standard you will use to connect Building C to Building D.
The distance is only 75 meters, so UTP is fine. The combined traffic is 125 Mbps (75 Mbps from C to D and 50 Mbps from A to D). With link aggregation, two 100BASE-TX trunk lines would do the job at minimum cost.
