Assuming that 802.11n uses the narrower 20-MHz channel and a single stream, which of the following answers matches a particular standard to its maximum bit rate? a. 802.11g: 54 Mbps 3. An enterprise campus LAN uses wired UTP Ethernet and wireless 802.11 LANs at the edge of the LAN. A network engineer uses a WLAN testing tool to view the frames moving through the WLAN, and he notes the speeds of the various frames in a single WLAN that uses a single access point.
Which of the following is true about what happens when a PC NIC connects to a switch using 100 BASE-T? 10. With a fiber optic cable, the core of the cable, through which light passes, is made of which of the following? 11. Which of the following is the type of transmitter used on a fiber optic link that provides the longest maximum distances?
It is smart to design the cabling with a 10:1 ration to support future bandwidth growth 4. What backbone cabling should you use? -UTP, ScTP, STP; 62.5/125 micron or 50/125 micron multimode optical fiber -You can also go with 8.3/125 micron single-mode optical fiber Chapter 5 1. What type of network cable would you use to connect the telecommunications room to the equipment room and what type of media would you specify inside the cable? -All in all, I would use Cat-5e to connect the telecommunication room to the equipment room.
Examine the offerings for Internet access to select the one that should be used. (10 points) AT&T offers a VPLS based service called “Wide Area Ethernet.” The advantage of this system is that it provides the feel of a LAN service (with self-managed connectivity) over AT&T MPLS network. The connection is designed to provide higher enough bandwidth (up to 10Gbs) to handle bandwidth intensive services such as VoIP while allowing customer provided encryption along with Quality of Services and Class of Services variations. I chose this option for a few different reasons; researching the costs of running your own fiber line between $35-70 thousand dollars a mile and having to maintain the lines yourself could be an inefficient way to go. MPLS networks have the advantage of running multiple protocols so the college could have different protocols for different features and with AT&T maintaining access and connections you will end up with a higher level of performance and guarantee of continuous connectivity.
| | | | 5. NETWORK TOPOLOGY Network Topology is defined as the arrangement of interconnections of several elements within a computer system. Wired and wireless LANs naturally use different topologies, the most commonly used topologies for wired LANs are bus, ring, star, tree and mesh. “A computer network topology is the physical communication scheme used by connected devices”. (Mitchell 2011).

Thus, it is more difficult to handle. Exercise 4.1.4: UTP Standards Complete the entries in Table 4-1. Use your textbook and Internet research to compose your answer. The common connector for interfacing UTP wires to a computer for networking is the Registered Jack 45 (RJ-45) interface. This uses eight copper wires (four twisted pairs) to complete the connection between interfaces.
Inside the cage a Cisco 6500 Series with a WS-X6816-10G-2TXL (Cisco Systems, 2012) fiber controller is needed. This is a 16-port fiber controller that will facilitate the high-speed data transfer over the internal network from switch to switch. In addition to this there is a need for 36 Cisco SPF-10G-SR modules to connect the fiber cable to the switches at both ends and to the servers. 3.1.2 Operating Systems The main operating system will be Windows Server 2012 Enterprise edition (Microsoft Inc, 2013). The operating system was chosen because it is an industry standard.
