Chapter 4: The Current Ethernet Specifications

1. B. On an Ethernet network, the MAC address (hardware address) is used for one host to communicate with another.

2. B. 100BaseTX uses CAT 5e and can run 200Mbps when using full duplex.

3. D. When one device sends a packet out on a network segment, all other devices on the same physical network segment must wait and let it be transmitted.

4. B. 100BaseTF means that you have an Ethernet over fiber cable implementation.

5. B. Carrier Sense Multiple Access with Collision Detection (CSMA/CD) helps packets that are transmitted simultaneously from different hosts share bandwidth evenly.

6. B. A 10GBaseSR cable can have a maximum distance of 990 feet (302 meters).

7. B. With half duplex, you are using only one wire pair with a digital signal either transmitting or receiving.
