Name: Lacey Mowery Date: September 23, 2011 ISSC340 Week 8 Assignment (3% of Grade) APUS/Kageorgis Pre-Assessment 8+9 & Activity 8-1 + 9-1: Reviewing transmission techniques concepts & advanced LAN and WAN technology concepts The purpose of this activity is to reinforce what you have learned so far about local area network technologies. 1. What is the major distinction between integrated network management systems and simpler network management systems? a. Integrated network management systems are useful only when integrating LANs into MANs or WANs. b. Integrated network management systems support only physical layer monitoring. c. Integrated network management systems use the five areas of functional management defined by the ISO. d. Integrated network management systems are made up of network monitoring and network analysis tools. 2. Which of the five functional areas maintains a record of lost tokens on a token ring network and sets an alarm for the network manager when the loss rate exceeds a threshold? a. Configuration management b. Fault management c. Performance management d. Security management. 3. What is a common function of a physical layer network management tool? (about 60 words) “ At the physical layer most management tools deal with the wires and connections of a network. Most networks are in need of this type of management. There are tools that help with these types of issues, such as oscilloscopes, TDRs, power meters, etc. .. These type of tools look for leaks in wires, cut connections, and failures or loss of power somewhere along the network. The time-domain reflectometer is the most commonly used tool for determining problems at the physical layer. There is also an optical TDR used to measure the functioning of optic fiber cables. There are very sophisticated management databases and software that include diagrams and visual maps of the network.” (Certification Partners LLC) 4. What technology would you use to transmit a signal over a DS4/T4 channel (139.264 Mbps)? a. SONET b. SMDS c. BISDN d. All of the above 5. True or false : Switched Multimegabit Data Service (SMDS) provides dedicated virtual circuits using cell relay to reduce the number of circuits required to interconnect LANs.
