    3. EIA
    4. IEC
  2. What are the characteristics of Ethernet 802.3? (Choose three.)

    1. Based on the CSMA/CD process
    2. Is a standard that has been replaced by Ethernet II
    3. Specifies the physical layer (Layer 1)
    4. Developed in the mid-1970s
    5. Specifies the MAC portion of the data link layer (Layer 2)
    6. Also referred to as thick Ethernet
  3. Which statement about an Ethernet address is accurate?

    1. The address used in an Ethernet LAN directs data to the proper receiving location.
    2. The source address is the 4-byte hexadecimal address of the NIC on the computer that is generating the data packet.
    3. The destination address is the 8-byte hexadecimal address of the NIC on the LAN to which a data packet is being sent.
    4. Both the destination and source addresses consist of a 6-byte hexadecimal number.
  4. Which statement about MAC addresses is accurate?

    1. A MAC address is a number in hexadecimal format that is physically located on the NIC.
    2. A MAC address is represented by binary digits that are organized in pairs.
    3. It is not necessary for a device to have a unique MAC address to participate in the network.
    4. The MAC address can never be changed.
  5. Which statement about NICs is accurate?

    1. The NIC plugs into a USB port and provides a port for connecting to the network.
    2. The NIC communicates with the network through a serial connection and communicates with the computer through a parallel connection.
    3. The NIC communicates with the network through a parallel connection and communicates with the computer through a serial connection.
    4. A NIC is also referred to as a switch adapter.
