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.
The loser cost method involves placing horizontal cross-connections and work group connections in the telecommunications room 3. Fiber to the telecommunication enclosure (FTTE) * Everything is run through a single point, * Odd are you paying more than you should be 1. The preferred UTP cabling media to support 10Gbps is Cat-5 or better. 2. Preferred Optical fiber to support 10Gbps is a single mode for long distance and multimode for short distance.
Mark Shuey Ivytech Community College Cint 121 Case Project 5.1 Network Design 9/23/2012 After assessing the current LAN, and keeping in mind cost. The upgrade I suggest is an Ethernet LAN with a physical star wired bus topologie, divided into four segments. The switches and routers are outdated and do need to be replaced. Cabling needs replaced. Good news is that the Network Interface Cards in all 17 workstations support the upgrade (10/100/1000Mbps).
The following costs were incurred in the first processing department during the month: The ending inventory was 90% complete with respect to materials and 45% complete with respect to conversion costs. Note: Your answers may differ from those offered below due to rounding error. In all cases, select the answer that is the closest to the answer you computed. To reduce rounding error, carry out all computations to at least three decimal places. 8. award: 1 out of 1.00 point How many units are in ending work in process inventory in the first processing department at the end of the month?
Case Projects 3-1, 3-2 IT/240 LAN Technologies Ralph Doleman 07/24/2014 Case 3-1 Case Project 3-1 Old-Tech Corporation has 10 computers in its main office area, which is networked in a star topology using 10 Mbps Ethernet hubs, and wants to add five computers in the manufacturing area. One problem with the existing network is data throughout. Large files are transferred across the network regularly, and the transfers take quite a while. In addition, when two or more computers are transferring large files, the network becomes unbearably slow for users. Adding the manufacturing computers will only make this problem worse and result in another problem.
Increase fault tolerance by splitting DHCP scopes. 2. Balance the load on your DHCP server by using the 80/20 rule for scopes 3. Allow remote administration of DHCP servers by comfiguring windows Firewall ports. | Question 4 | What is the name of the computer you are working from?
Desktop workstation backups generally take less than 10 minutes. Using the format below, describe the steps necessary to recover a desktop workstation computer that encounters a disk drive failure at 5:30 a.m. local time. The user arrived at work and found that the computer would not boot. Answer the following questions: 1. How much data has been modified between the last backup and the time of failure?
* Its benefits are price it’s less expensive to build and run. But if one of the lines goes down then your whole network goes down. Exercise 7.2.4 Circuit classification | Total Bandwidth (Mbps) | Features and summary | T1 | 1.544 | Uses 24 channels to communicate. | E1 | 2.048 | Uses 32 channels to communicate. | T3 | 44.7 | Uses 672 channels to communicate.
IP addresses 192.168.103.1 will be used for the internal interface address of the SonicWall and 192.168.103.2 will be used for the customer web server. The remaining 252 IP addresses will be available for local and remote employee devices. The SonicWall-Ne WAPs will be used at this location as well. Because of the static VPN connection between New York and Austin, these WAPs will be centrally managed by the SonicWall in the Austin office. Employees that travel between locations will easily be able to connect their devices.
Traneshia Kitchens Dr. Culver CIS 500 July 28, 2012 Compare and contrast 3G wireless networks to 4G networks In today’s society, 3G networks deliver average download speeds about one-tenth of that rate. 4G networks do not have a circuit-switched subsystem. 4G is based on the packet-based Internet Protocol (Turner, E. & Volonino, L., 2011 pg. 96). The 3G service that people are using today is at least fast now compared to a year ago.
