CCNA Module 7

1 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



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

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

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

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



4 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


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
