``` 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 ```
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
``` 2. Which of the following 10 Gigabit Ethernet standards has the greatest maximum transmission distance? ❍ A. 10GBaseSR ❍ B. 10GBaseER ❍ C. 10GBaseLR ❍ D. 10GBaseXR ```
2. 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
``` 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 ```
3. 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
``` 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 ```
4. 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
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.
10GBaseLR/LW
49
When it comes to WANs that require greater transmission distances, the Ethernet _______ standards come into play
10GBaseER/EW
50
A type of bayonet connector used on | RG-58 coaxial cables
BNC connector
51
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).
Category 3 (CAT3)
52
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
Category 5 (CAT5)
53
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).
Category 5e (CAT5e)
54
Designed to support frequencies of up to 250 MHz, ____ cables easily handle 1000Base-T Gigabit Ethernet traffic and, with special installation considerations, 10Gbase-T
Category 6 (CAT6
55
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.
Augmented Category 6 (CAT6a)
