• 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

• 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

• 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
