How Much Do You Know About Mac And Ethernet?
A MAC is a unique identifier allocated to a Network Interface Controller (NIC) for communications which are used as a network address. Whereas, Ethernet is a way of connecting two or more computers together in a local area network. This quiz has been developed to test your knowledge of MAC, Ethernet and NIC. So, let's try out the quiz. All the best!
- 1.Where does the MAC address originate?
- A.
DHCP server database
- B.
Configure by the administrator

Burned into ROM on the NIC card
- D.
Network configuration on the computer

Included in the creation of the processor chip

Logical Layer Control
- C.
Media Access Control
- D.
Logical Link Communication

Media Access Communication
- 3.Why do hosts on an Ethernet segment that experience a collision use a random delay before attempting to transmit a frame?
- A.
A random delay value for each device is assigned by the manufacturer.
- B.
A random delay value could not be agreed upon among networking device vendors
- C.
A random delay helps prevent the stations from experiencing another collision during the transmission
- D.
A random delay value could not be agreed upon among networking device vendors
- 4.A technician wants to increase the available bandwidth for the workstation by allowing the switch and the NIC on the workstation to transmit and receive simultaneously. What will permit this?
- A.
CSMA/CD
- B.
Full-duplex
- C.
FastEthernet
- D.
Crossover cable
- 5.When a collision occurs in a network using CSMA/CD, how do hosts with data to transmit respond after the backoff period has expired?
- A.
The hosts return to a listen-before-transmit mode.
- B.
The hosts creating the collision have priority to send data
- C.
The hosts creating the collision retransmit the last 16 frames.
- D.
The hosts extend their delay period to allow for rapid transmission.
- 6.What are three functions of a NIC in a PC? (Choose three)
- A.
A NIC connects the PC to the network media.
- B.
A NIC detects collisions on the Ethernet segment.
- C.
A NIC checks the formatting of data before it is transmitted.
- D.
A NIC passes the contents of selected frames to the upper OSI layers.
- E.
A NIC acknowledges and retransmits data that was not received properly
- 7.Which characteristics describe carrier sense multiple access collision detect (CSMA/CD)? (Choose three)
- A.
Point-to-point
- B.
Nondeterministic
- C.
Connection-oriented
- D.
Collision environment
- E.
First-come, first-served approach
- 8.Which two devices can provide full-duplex Ethernet connections? (Choose two)
- A.
Hub
- B.
Modem
- C.
Repeater
- D.
NIC
- E.
Layer 2 switch
- 9.In which two layers of the OSI model does Ethernet function? (Choose two)
- A.
Session
- B.
Transport
- C.
Network
- D.
Data link
- E.
Physical
- 10.All hosts are in listen mode, Host 1 and Host 4 both transmit data at the same time. How do the hosts respond on the network? (Choose two)
- A.
Host 1 and 4 may be operating full duplex so no collision will exist
- B.
The hub will block the port connection to Host 4 to prevent a collision.
- C.
After the end of the jam signal, a backoff algorithm is invoked.
- D.
Host 1 and 4 are assigned shorter backoff values to provide them priority to access the media.
- E.
If a host has data to transmit after the backoff period of that host, the host checks to determine if the line is idle, before transmitting.
- 11.Host A is communicating with host F. What happens to a frame sent from host A to host F as it travels over the Ethernet segments.
- A.
The frame format is modified as it passes through each switch.
- B.
The frame format remains the same across each Ethernet segment.
- C.
The frame format is modified as the media speed changed at switch B and switch E.
- D.
The frame format is modified as the media material changes between copper and fiber at switch C and switch D
- 12.How many hexadecimal digits are in a MAC address?
- A.
2
- B.
8
- C.
12
- D.
16
- E.
32
- 13.At what layer of the OSI model does a MAC address reside?
- A.
1
- B.
2
- C.
3
- D.
4
- E.
7
- 14.A router has an Ethernet, Token Ring, serial, and an ISDN interface. Which interfaces will have a MAC address?
- A.
Serial and ISDN interfaces
- B.
Ethernet and Token Ring interfaces
- C.
Ethernet and ISDN interfaces
- D.
Token Ring and serial interfaces
- 15.In an Ethernet LAN, how does the NIC know when it can transmit data?
- A.
An Ethernet NIC transmits data as soon as the frame is received.
- B.
An Ethernet NIC transmits data as soon as the NIC receives a token.
- C.
An Ethernet NIC transmits data when it senses a collision.
- D.
An Ethernet NIC transmits data after listening for the absence of a signal on the media.
- 16.The small office network shown in the exhibit consists of four computers connected through a hub. Which configuration would cause collisions and errors on the network?
- A.

- B.
FastEthernet
- C.
