1. 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

 

2. Which RJ-45 pins are used to transmit and receive data in an Ethernet 100BASE-TX Category 5 UTP cable? (Choose two.)

1 and 2

3 and 6

4 and 5

7 and 8

 

3. 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

 

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

100BASE-5

100BASE2

1000BASE-F

100BASE-FX

100BASE-TX

 

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

physical layer

data link layer

network layer

can be implemented over copper and fiber

primarily used between workstations option

 

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

10BASE-T

100BASE-T

100BASE-FX

1000BASE-LX

 

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
