Part 1
We have 4 devices connected to an 8-port Hub. Each device is numbered starting with 0, and each port of the Hub is also numbered starting with 0.
Device 0 has MAC address 78-2B-CB-70-72-36 and is connected to port 0 of the Hub.
Device 1 has MAC address 00-14-C1-E6-2A-5D and is connected to port 1 of the Hub.
Device 2 has MAC address E4-48-C7-F5-AA-70 and is connected to port 2 of the Hub.
Device 3 has MAC address 00-13-E8-C6-57-3C and is connected to port 3 of the Hub.
The Hub and all the devices are cold-started, and the following Ethernet frames are sent on the network in sequence:
Frame 0 (source 00-14-C1-E6-2A-5D destination 00-13-E8-C6-57-3C)
Frame 1 (source 00-13-E8-C6-57-3C destination E4-48-C7-F5-AA-70)
Frame 2 (source 00-14-C1-E6-2A-5D destination 78-2B-CB-70-72-36)
Frame 3 (source 00-14-C1-E6-2A-5D destination 00-13-E8-C6-57-3C)
The following questions ask you to find out which of these frames will be heard at selected ports. Your answer must be a comma-separated list of frame numbers in the order heard at the port.
1a. Assuming you are monitoring port 0 of the Hub, which of the frames would be heard at this port?
1b. Assuming you are monitoring port 1 of the Hub, which of the frames would be heard at this port?
1c. Assuming you are monitoring port 2 of the Hub, which of the frames would be heard at this port?
1d. Assuming you are monitoring port 3 of the Hub, which of the frames would be heard at this port?
Part 2
We have 4 devices connected to an 8-port Switch. Each device is numbered starting with 0, and each port of the Switch is also numbered starting with 0.
Device 0 has MAC address 34-97-F6-DD-9B-71 and is connected to port 0 of the Switch.
Device 1 has MAC address 24-76-7D-C2-8F-75 and is connected to port 1 of the Switch.
Device 2 has MAC address 34-97-F6-24-EC-4D and is connected to port 2 of the Switch.
Device 3 has MAC address 00-01-24-8B-A9-60 and is connected to port 3 of the Switch.
The Switch and all the devices are cold-started, and the following Ethernet frames are sent on the network in sequence:
Frame 0 (source 34-97-F6-DD-9B-71 destination 00-01-24-8B-A9-60)
Frame 1 (source 34-97-F6-24-EC-4D destination 24-76-7D-C2-8F-75)
Frame 2 (source 24-76-7D-C2-8F-75 destination 34-97-F6-DD-9B-71)
Frame 3 (source 24-76-7D-C2-8F-75 destination 00-01-24-8B-A9-60)
Frame 4 (source 34-97-F6-24-EC-4D destination 00-01-24-8B-A9-60)
Frame 5 (source 34-97-F6-24-EC-4D destination 34-97-F6-DD-9B-71)
The following questions ask you to find out which of these frames will be sent out from selected ports. Your answer must be a comma-separated list of frame numbers in the order sent out from the port.
2a. Assuming you are monitoring port 0 of the Switch, which of the frames would be sent out from this port?
2b. Assuming you are monitoring port 1 of the Switch, which of the frames would be sent out from this port?
2c. Assuming you are monitoring port 2 of the Switch, which of the frames would be sent out from this port?
2d. Assuming you are monitoring port 3 of the Switch, which of the frames would be sent out from this port?
