Experiences 2

• Twisted pair category 5 wiring:
  They had a run of 180 m and wanted to know what you would connect in between to make it work (repeater)
  
• Many questions about segmenting a LAN and what to use (routers).
  
• Which protocols are routable.
  • Routable prots are: XNS, OSI, IP, IPX, Appletalk (barf), and DECnet.
  • DLC, LAT, NetBEUI) are not routable.

• IPX/SPX is great for Peer-to-Peer networking if NetBEUI is not a choice
  
• You tested the Thinnet coax and got the reading 0ohm to (infinite)ohm, same with T Connector, and the terminator 50 ohm. What would you replace? The cable, T Connector or terminator
  
• If you wanted to find out the available bandwidth what would you use. TDR, Voltmeter, Performance monitor, and something else I never heard of.
  
• There were a number of "what device would you use to test __________" type questions.
  
• Sue can not see network. She has logged on with X configuration. You (the admin) break out the TDR and analzye the cable. Here are the ratings you get

  What's wrong?
  
• What is the benefit of NDIS and ODI?
  
• Which of the following supports compression and error control: PPP and SLIP
  
• What OSI level does a bridge work at?
  
• What OSI level does a router work at?
  • Routers operate at the Network layer

• What OSI level does a gateway work at?
  
• Which of the following examines packets: performance monitor, TDR, Protocol Analyzer, etc.
  
• Difference between share level passwords and access/user level security
  
• Which of the following should be used for at least 100mbps: ATM, X25, 52kbps Digital line
  
• Which is a feature of Win NT Workstation:
  • Shared resources with passwords (incorrect)
  • User level passwords (correct)

• Which is a feature of Win 95:
  • Shared resources with passwords (correct)
  • User level passwords (incorrect)

• Understand that if you are upgrading to 100BaseTX, you will need to also change network cards, hubs, etc
  
• Know what COM ports usually use what IRQ's
  
• Know how to troubleshoot network cards: IRQ, Base I/O, etc
  
• Know that a terminator impedance is usually always 50 ohms
  
• Know the difference between a file & print server and an application server, ie the application server performs processor calculations
  
• Know that RG 58 U cable (solid core conductor) is NOT compatible with for ThinNet and is different that RG 58 A/U which IS used for ThinNet
  
• You have a 5 user peer-peer WFW network. What do you use as a protocol?
  
• Which switching technology would allow a WAN link of 100mbps.
  • The MS NE self training text reads "Most commercial ATM boards will transmit data at about 155 Mbps, but theoretically 1.2 Gbps is possible."
