Termination of Thinnet BUS network:

  1. Must only be terminated with two terminators. Any more or any less is wrong.
  2. Terminators must be 50 ohm.
  3. Only one end of the bus should be grounded. If both ends are grounded, you’re going to have problems.

 

What communication protocol allows for nearly unlimited bandwidth to be allocated as needed?

A: Frame Relay

 

Know your maximum cable lengths and bandwidth limits.

10baset or 100baseX CAT 5 UTP = 100 Meters and up to 100Mbps

10base2 Thinnet Coax (RG58 A/U) = 185 Meters and up to 10Mbps

10base5 Thicknet Coax (RG8 or RG11) = 500 Meters and up to 10Mbps

 

No questions on infared or wireless radio, etc..

 

No questions on packet switching, virtual circuits, etc..

 

Know your connector types.

CAT 5 UTP = RJ45

Thinnet = BNC/BNC-T/50ohm terminators

Thicknet = Usually uses a transceiver with AUI connector

UTP/STP = RJ45

 

Know that routers work on the network layer of the OSI model.

 

Know when a gateway should be used.

 

Know your routable and non-routable protocols.

 

Know your IRQ settings, there will be questions like:

Q: Your workstation uses a serial mouse on COM1, an internal modem on COM2 and a laser printer on

LPT1. Your NIC is set to use IRQ 3 and the NIC is not working. What device is conflicting?

A: COM2 uses IRQ3.

 

Know RAID specs. You will have questions like:

 

You have two network servers, both running Win NT server. You must ensure that data is extremely secure and that you have a fail safe disaster recovery plan in place. Network downtime should be kept to an absolute minimum if there is a disaster. Which method of data redundancy should you choose?

 

  1. RAID Level 0 and a tape backup rotation with tapes stored on site.
  2. RAID Level 1 and a tape backup rotation with tapes stored off site.
  3. RAID Level 5 and a tape backup rotation with tapes stored off site.
  4. Tape Backup rotation with tapes stored off site.

 

You have a workstation that cannot connect to the network. All other workstations can access all network resources. What is your first step in troubleshooting?

 

  1. Run diagnostics on the workstation’s NIC.
  2. Run diagnostics on the server’s NIC.
  3. Make sure the network is properly terminated.
  4. Re-install the workstation’s network client software.

 

 

 

You have a workstation that can NO LONGER access the network. Which is most likely the problem?

 

  1. The frame type on the workstation’s NIC is incorrectly configured.
  2. The network cabling to the workstation’s NIC is loose or disconnected.
  3. The workstation is running the wrong network communication protocol.
  4. The workstation’s RAM is defective.

 

When running WINS to resolve NetBIOS computer names, which is it important? Check all that apply:

  1. To make sure that no two computers on the network has the same name.
  2. To make sure that no computer has the same name as a domain on the network.
  3. To make sure that no computer has the same name as a workgroup on the network.
  4. To make sure that no computer has the same name as a server on the network.

 

What tool can be used to measure the bandwidth of a network medium?

  1. Time Domain Reflectometer
  2. Protocol Analyzer
  3. Advanced Cable Tester
  4. Oscilloscope

 

Which Operating Systems can assign SHARE level security? Check all that apply:

  1. Windows NT Workstation
  2. Windows 95
  3. Windows for Workgroups 3.11
  4. Windows NT Server

 

Know that User level security is more secure than share level security.

 

You have a WAN with 25 servers and 1000 workstations (500 Windows NT, 300 Macs, 100 Unix and 75 DOS). The network currently runs NetBEUI, TCP/IP and Apple Talk. You are having a problem with broadcast storms. Your brouters are set to broadcast messages across all segments.

 

Required: You must resolve the broadcast storm problem.

No additional protocols may be loaded on the workstations.

 

Optional: Cost must be kept to a minimum.

Workstations should still be able to communicate using computer names as well as IP addresses.

 

Proposed Solution: Turn off broadcasting on your brouters. Remove NetBEUI from your servers and workstations. Enable DHCP and DNS.

 

You have offices in Atlanta, Chicago and Los Angeles. All of your offices must be able to communicate with all other offices at 1Mbps and communications should continue between all offices at 1Mbps even if one link should fail.

 

Proposed: Two T1 links and one 9600 baud asynchronous line.

 

Answer: Doesn’t meet required results. All offices can’t communicate with all other offices at 1Mbps if one of the T1 links goes out.

 

Same question as above, but the proposed solution is a 16 port RAS server at each location running 8 28.8Kbps connections synchronously.

 

Same answer. 8 x 28.8 doesn’t make a 1Mbps connection.

 

Know that NWLink doesn’t have to be used for connectivity to Netware servers. It can be used as a stand-alone protocol to connect NT workstations to NT servers just like NetBEUI or TCP/IP.
