In the LAN for a small office, some user devices connect to the LAN using a cable, while others connect using wireless technology (and no cable). Which of the following is true regarding the use of Ethernet in this LAN?

Only the devices that use cables are using Ethernet.

Only the devices that use wireless are using Ethernet.

Both the devices using cables and those using wireless are using Ethernet.

None of the devices are using Ethernet.

Correct! Wrong!

Which of the following is true about Ethernet crossover cables for Fast Ethernet?

None of the other answers is correct.

The cable can be up to 1000 meters long to cross over between buildings.

Pins 1 and 2 are reversed on the other end of the cable.

Pins 1 and 2 on one end of the cable connect to pins 3 and 4 on the other end of the cable.

Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable.

Correct! Wrong!

Which of the following is true about the format of Ethernet addresses?

Each manufacturer puts a unique OUI code into the first half of the address.

The part of the address that holds this manufacturer’s code is called the MAC.

The part of the address that holds this manufacturer’s code has no specific name.

Each manufacturer puts a unique OUI code into the first 2 bytes of the address.

Correct! Wrong!

Which of the following terms describe Ethernet addresses that can be used to send one frame that is delivered to multiple devices on the LAN?

Unicast address

Burned-in address

Broadcast address

Correct! Wrong!

Which of the following describe a MAC address?

Layer 1 address

32 bits

Layer 3 address

48 bits

Correct! Wrong!

Which of the following is true about the Ethernet FCS field?

It is 2 bytes long.

Ethernet uses FCS for error recovery.

It is used for encryption.

It resides in the Ethernet trailer, not the Ethernet header.

3,6

2,6

1,2

1,3

Correct! Wrong!

Which of the following is true about the CSMA/CD algorithm?

The algorithm never allows collisions to occur.

The algorithm works with only two devices on the same Ethernet.

Collisions can happen, but the algorithm defines how the computers should notice a collision and how to recover.

None of the other answers is correct.
