Take Assessment - Module 7 Exam - CCNA 1 Networking Basics (Version 3.1)

 Time Remaining:

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

1 and 2
3 and 6
4 and 5
7 and 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

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?
