| 1) | You have two networks, the first supports a maximum bandwidth of 100Mbit/s and the second 10Mbit/s. Which component do you have to use, if you want to connect the two networks without loss of speed? | |
| a) | Router | |
| b) | Hub | |
| c) | Switch | |
| d) | Transceiver | |
| 2) | Which is the widespread plug-type in today's ethernet networks? | |
| a) | AUI | |
| b) | RJ45 | |
| c) | RJ11 | |
| d) | BNC | |
| 3) | Imagine the following network configuration: There are several hosts ('constable', 'roy', 'hodler', 'davinci') running with a network speed of 100Mbit/s. There are also some other hosts ('escher', 'kandinsky') running at 10Mbit/s. Constable, roy and hodler are connected to hub1. Davinci, escher and kandinsky are connected to hub2. The two hubs are directly connected together with a crossed cable. If roy sends some data to davinci, which maximum bandwidth will you get? | |
| a) | 10Mbit/s | |
| b) | 33.3Mbit/s | |
| c) | 55Mbit/s | |
| d) | 100Mbit/s | |
| 4) | Take the same network as used in question 3. But now, we have switches instead of hubs. Which maximum bandwidth will you get now, if roy sends some data to davinci? | |
| a) | 10Mbit/s | |
| b) | 100Mbit/s | |
| c) | 200Mbit/s | |
| d) | 1000Mbit/s | |
| 5) | There are two hosts ('asterix', 'obelix'). There is a printer connected to asterix. Now, obelix also want to use this printer. Both hosts have an ethernet network interface card installed. You have two straight cables, two crossed cables and a four port hub. Which of the following connections will work, so that obelix can print on that printer? | |
| a) | Connect both hosts together with one straight cable. | |
| b) | Connect both hosts with crossed cables to the hub. | |
| c) | Connect asterix with a straight and obelix with a crossed cable to the hub. | |
| d) | Connect both hosts with straight cables to the hub. | |
| 6) | What are the advantages of a switch compared with a hub? (more than one answer possible) | |
| a) | higher bandwidth | |
| b) | packets will only be delivered to selected nodes | |
| c) | eliminates collisions | |
| d) | provides a connection to the internet | |
