Q 
1. You troubleshoot a network using 1000BaseCX cable, and you suspect that the maximum length has been exceeded. What is the maximum length of 1000BaseCX cable?
❍ A. 1,000 meters 
❍ B. 100 meters
❍ C. 25 meters 
❍ D. 10,000 meters
A
  1. C. The 1000BaseCX standard specifies Gigabit Ethernet transfer over Category 5 UTP cable. It uses STP twisted-pair cable and has a 25-meter length restriction.
45
Q 
2. Which of the following 10 Gigabit Ethernet standards has the greatest maximum transmission distance?
❍ A. 10GBaseSR 
❍ B. 10GBaseER
 ❍ C. 10GBaseLR 
❍ D. 10GBaseXR
A
  1. B. The 10GBaseER standard specifies a maximum transmission distance of 40,000 meters. The 10GBaseSR standard specifies a maximum transmission distance of 300 meters, whereas 10GBaseLR specifies a maximum transmission distance of 10,000 meters. 10GBaseXR is not a recognized 10 Gigabit Ethernet standard.
46
Q 
3. Your manager has asked you to specify a high-speed 10GbE link to provide con- nectivity between two buildings 3km from each other. Which of the following IEEE standards are you likely to recommend?
❍ A. 10GBaseLR 
❍ B. 10GBaseSR 
❍ C. 10GBaseT4 
❍ D. 10GBaseFL
A
  1. A. 10GBaseLR can be used over distances up to 10km. 10GBaseSR can only be used up to a maximum distance of 300 meters. 10GBaseT4 and 10GBaseFL are not recognized 10-Gigabit Ethernet standards.
47
Q 
4. In a 100BaseTX network environment, what is the maximum distance between the device and the networking equipment, assuming that no repeaters are used? 
❍ A. 1,000 meters
❍ B. 100 meters
❍ C. 500 meters
❍ D. 185 meters
A
  1. B. 100BaseT networks use UTP cabling, which has a maximum cable length of 100 meters. Answer A is incorrect because this distance could be achieved only with UTP cabling by using repeaters. Answer C specifies the maximum cable length for 10Base5 networks. Answer D specifies the maximum cable length for 10Base2 networks.
48
Q

re not used over multimode fiber. Instead, they offer greater distances using single-mode fiber. Both the LR and LW standards are designed to be used over long-wavelength single-mode fiber, giving it a potential transmission range of anywhere from 2 meters to 10 kilometers.

A

10GBaseLR/LW

49
Q

When it comes to WANs that require greater transmission distances, the Ethernet _______ standards come into play

A

10GBaseER/EW

50
Q

A type of bayonet connector used on

RG-58 coaxial cables

A

BNC connector

51
Q

Long the standard for telephone communications, _____ cables
were used by the first UTP-based Ethernet networks (called 10Base-T). _____ cables
supported frequencies up to 16 megahertz (MHz).

A

Category 3 (CAT3)

52
Q

Designed for 100Base-TX Fast Ethernet networks and supporting
frequencies up to 100 MHz, _____ cabling was dropped from the latest version of the
TIA/EIA cabling standards

A

Category 5 (CAT5)

53
Q

Still rated for frequencies up to 100 MHz, ____ cable is designed to support full duplex transmissions over all four wire pairs, as on 1000Base-T Gigabit Ethernet networks. The standard calls for increased resistance to Near-End Crosstalk (NEXT) and Return Loss (RL) and also adds testing requirements for Power Sum Near-End Crosstalk (PS-NEXT), Equal-Level Far-End Crosstalk (EL-FEXT), and Power Sum Equal-Level Far-End Crosstalk (PS-ELFEXT).

A

Category 5e (CAT5e)

54
Q

Designed to support frequencies of up to 250 MHz, ____ cables easily handle 1000Base-T Gigabit Ethernet traffic and, with special installation considerations, 10Gbase-T

A

Category 6 (CAT6

55
Q

Created for 10Gbase-T installations with cable segments up to 100 meters long, CAT6a supports frequencies up to 500 MHz and includes an Alien Crosstalk (AXT) testing requirement. ____ cables use larger conductors and leave more space between the wire pairs, meaning that the outside diameter of the sheath is larger than a CAT6 cable, about 0.29 to 0.35 inches. ____ was added to the most recent version of the TIA/EIA standards in 2008.

A

Augmented Category 6 (CAT6a)
