  3. 3Which statement about an Ethernet address is accurate?
    1. AThe address used in an Ethernet LAN directs data to the proper receiving location.
    2. BThe source address is the 4-byte hexadecimal address of the NIC on the computer that is generating the data packet.
    3. CThe destination address is the 8-byte hexadecimal address of the NIC on the LAN to which a data packet is being sent.
    4. DBoth the destination and source addresses consist of a 6-byte hexadecimal number.
  4. 4Which statement about MAC addresses is accurate?
    1. AA MAC address is a number in hexadecimal format that is physically located on the NIC.
    2. BA MAC address is represented by binary digits that are organized in pairs.
  5. 5Which statement about NICs is accurate?
    1. AThe NIC plugs into a USB port and provides a port for connecting to the network.
    2. BThe NIC communicates with the network through a serial connection and communicates with the computer through a parallel connection.
    3. CThe NIC communicates with the network through a parallel connection and communicates with the computer through a serial connection.
    4. DAn NIC is also referred to as a switch adapter.

    1. AUTP cable is an eight-pair wire.
    2. BAn insulating material covers each of the individual copper wires in UTP cable.
    3. CThe wires in each pair are wrapped around each other.
    4. DThere is limited signal degradation from EMI and RFI.
    5. EThere are seven categories of UTPa cable.
  8. 8Which of the following statements about the functions of a hub are accurate? (Choose two.)
    1. AA hub extends an Ethernet LAN.
    2. BA hub reduces the size of a collision domain.
    3. CAdding a hub eliminates the need for users on a network segment to compete for the same bandwidth.
    4. DA hub is a data link layer device.
    5. EA hub amplifies the data signal before retransmitting it.
  9. 9Which of the following statements best describe collisions? (Choose three.)
    1. ACollisions occur when two or more stations on a shared media transmit at the same time.
    2. BLarger segments are less likely to have collisions.
    3. C. In a collision, the frames are destroyed, and each station in the segment begins a random timer that must be completed before attempting to retransmit the data.
    4. DAdding a hub to a network can improve collision issues.
    5. ECollisions are by-products of a shared LAN.
    6. FMore segments on a network mean greater potential for collisions.
