You are putting connectors on a patch cable. One end is wired so that pins 1 and 2 are orange white and solid orange, pins 3 and 6 are green white and solid green, pins. 4 and 5 are solid blue and blue white, and pins 7 and 8 are brown white and solid brown. Which of the following is correct about the way that the other end should be wired? Pins 1 and 2 should be green white and solid green. Pins 1 and 2 should be orange white and solid orange. Pins 1 and 2 should be brown white and solid brown. Pins 1 and 2 should be blue white and solid blue. After changing to Cox High Speed Internet from Verizon DSL, there are times when my Internet connection is not working at all. When I look at the cable modem, the indicator lights showed that my cable is connected but that the modem was "scanning for the network connection." The connection is typically off for a few minutes, and then resumes normal operation. Which of the following quality of service measures is being violated? Availability Attenuation Transmission Speed Latency Which of the following types of antennas is best for mobile users? Adaptive Dish Wideband Omnidirectional Which of the following is not a wireless propagation problem? Shadow Zone Crosstalk Interference Rapid attenuation with distance Multipath Interference When radio waves cannot pass through a large dense object, this creates behind the object. refractive interference a shadow zone multipath interference spread spectrum The FCC allows device makers to produce devices that operate at 900MHz,2.4 GHz,5GHZ, and 60GHz. However, the 900MHz and 60GHz bands are generally unused. Which of the following describes why 2.4GHZ and 5GHZ are in the "Golden Zone" of wireless spectrum? The ideal wavelength of wireless signals roughly corresponds to the color of gold. Lower frequencies propagate better, but there is more spectrum available in higher frequencies. The publicly accessible bandwidths at 2.4GHz and 5GHz are for the "proletariat" while the higher frequencies are for the "nobility." Dish antennas that are focused to a perfect point relative to their satellite are in the "zone." Which of the following describes the relationship between bandwidth and transmission speed? Dish antennas have slower speed because the width of the signal that they can send is smaller. Channels at a higher frequency always have a higher transmission speed. When bands march in a parade, wider bands always move faster. Doubling the bandwidth doubles the maximum possible transmission speed. On the cover of this week's NetworkWorld, there is a teaser that says: "The Wi-Fi Divide: WLANs find a home in tiled work areas, but deployment lags in carpeted enterprise environments. " Which of the following could I expect to read in the article (in essence, that would be true)? That tiled work areas are more popular for Wireless LANs because carpeting gives off static electricity and people often spark access points. Places like hospitals and retailers are implementing Wireless LANs because their employees walk around a lot, while more traditional "cubicle farms" in office buildings work better with wired access. It's easier to attach wireless access points to a tiled floor than to a carpeted floor. If wireless is available, people tend to surf the Internet on their laptops while they are waiking around. Because this requires two hands, coffee drinkers try to balance their cups on the keyboards of their laptops, and often spill. Tiled floors are better for Wireless LANs because they are easier to clean if someone spills coffee on them. If a wireless transmitter and receiver are in the same room, walls and other objects can create even if they do not come between them. shadow zones multipath interference inverse square law attenuation crosstalk On June 12,2009 , all over-the-air television stations stopped broadcasting analog signals, which freed several megahertz of spectrum. TV stations continued to broadcast their signals in standard (SD) or high definition (HD) over the spectrum they kept - no new spectrum was used, and no stations went off the air. Knowing what you know about networking, which of the following is obviously a false statement about this government program? Television stations stopped transmitting television signals over certain frequency ranges. Old televisions stopped working because they couldn't understand digital signals, so the government subsidized special boxes that converted digital television signals to analog. Digital signals require more bandwidth than analog signals for the same picture quality. Cell phone companies paid over $19 billion for the wireless spectrum freed under this program. Your company is expanding and has leased space in the high-rise across the street. You want the two offices to be able to use the same network. Which of the following is something you would be allowed to do (without a government permit) to connect two buildings across a public street? Connect them wirelessly using 802.11 technology. Lay coaxial cabling across the street, protected from car traffic by several layers of duct tape. Knot a UTP cable to an arrow, climb to the roof and shoot the arrow between the two buildings.
