Ethernet Quizzes & Trivia

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!

    • C. 

      A random delay helps prevent the stations from experiencing another collision during the transmission

  • 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.

      Point-to-point

    • B. 

      Nondeterministic

    • C. 

      Connection-oriented

    • D. 

      Collision environment

    • E. 

      First-come, first-served approach

      Session

    • B. 

      Transport

    • C. 

      Network

    • D.

  • 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.
