Reflective Question 9.1.3

Were there different types of cables/media used to connect devices?

• Yes

• No

Did the cables change the handling of the PDU in any way?

• Yes

• No

Did the Hub lose any of the information that it received?

• Yes

• No

What does the Hub do with MAC addresses and IP addresses?

• Forwards data packets based on MAC addresses.

• Assigns IP addresses to connected devices.

• Filters traffic based on IP addresses.

• Does nothing with MAC addresses and IP addresses

Did the wireless Access Point do anything with the information given to it?

• Yes, it repackaged it as wireless 802.11 frames.

• No, it did not do anything with the information.

• Yes, it encrypted the information.

• Yes, it amplified the signal.

Was any MAC or IP address lost during the wireless transfer?

• Yes

• No

What was the highest OSI layer that the Hub and Access Point used?

• layer 1

• layer 2

• layer 3

• layer 4

Did the Hub or Access Point ever replicate a PDU that was rejected with a red “X”?

• Yes

• No

When examining the PDU Details tab, which MAC address appeared first, the source or the destination?

• Source

• Destination

Why would the MAC addresses appear in this order?

• A switch can begin forwarding a frame to a known MAC address more quickly if the destination is listed first.

• The order of MAC addresses in a frame is arbitrary and has no impact on network performance.

• The source MAC address must always be listed before the destination MAC address in an Ethernet frame.

• The order of MAC addresses is determined by the network protocol, not by the switch.
