1 Which Ethernet standard does the IEEE 802.3 standard recommend for backbone installations?

  • 10BASE-T
  • 100BASE-T
  • 100BASE-FX
  • 1000BASE-LX*


2 Which statements describe Gigabit Ethernet technology? (Choose two.)

  • operates at 100 Mbps
  • typically used for backbone cabling*
  • requires shielded twisted-pair cabling
  • can be implemented over copper and fiber *
  • primarily used between workstations option


3 Which of the following are Fast Ethernet technologies? (Choose two.)

  • 100BASE-5
  • 100BASE2
  • 1000BASE-F
  • 100BASE-FX*
  • 100BASE-TX*


4 To make sure timing limitations are not violated when implementing a 10 Mbps Ethernet network involving hubs or repeaters, a technician should adhere to which rule?

  • the 4-5-3 rule
  • the 6-4-2 rule
  • the 3-4-5 rule
  • the 5-4-3 rule*


5 At which OSI layer do the differences between standard Ethernet, Fast Ethernet and Gigabit Ethernet occur?

  • physical layer*
  • data link layer
  • network layer
  • transport layer


6 How does 1000BASE-T use the UTP wire pairs to accomplish transmission?

  • two pairs are used to transmit and two pairs are used to receive
  • one pair is used to transmit, one pair is used to receive, one pair is used for clocking, and one pair is used for error correction
  • all four pairs are used in parallel by both hosts to transmit and receive simultaneously*
  • two pairs of wires are used as in 10BASE-T and 100BASE-TX

  • 7 and 8


8 What is the maximum distance that 10BASE-T will transmit data before signal attenuation affects the data delivery?

  • 100 meters*
  • 185 meters
  • 300 meters
  • 500 meters


9 Which media types can be used in an implementation of a 10BASE-T network? (Choose three.)

  • Category 5 UTP*
  • Category 5e UTP*
  • Category 3 UTP*
  • coaxial cable
  • multi-mode fiber
  • single mode fiber


10 Which of the following Ethernet technologies are considered legacy Ethernet? (Choose three.)

  • 10BASE2*
  • 10BASE5*
  • 10BASE-T*
  • 100BASE-T
  • 100BASE-FX
  • 100BASE-TX
