• 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
