t--C-----C------C-----C--t

C=client
t=terminator(50ohm) (3x)
coax RG-58A/U

Problem in this network: 3 terminators. Network must only be terminated with 2 terminators.

A: Change the network by eliminating the peace of wire to the server (about 35 mtr.) and connect the server like the computers with a BNC T connector.

Q: What instrument to use to measure the bandwith of a UTP5 cable?

A: I said a protocol analyser.

Q: What supports compession and dynamic IP addressing?

A: PPP

Q: What operating system supports user level security (choose 3 options)?

A: I chose: WFW, WinNT-workstation and WinNT-server.

Q: Network Interface Card installed in PC with SCSI HD. Hard drive won't boot. Removing NIC and hard drive boots again. Whats the problem?

A: IRQ settings (NIC: IRQ5)

Q: What would you use to manage and monitor Routers, Bridges, etc.

A: SNMP (Simple Network Management Protocol, p.461)

If you are unable to connect to the network with one computer, it will be one of the following problems: incorrect frame type (ethernet/arcnet), wrong IRQ or wrong tranciever type.

Know about connection (reliable) and connectionless (fast but unreliabel) modes.

Frame relay, offers bandwidth on demand (p.597)

Raid level5 (p.498) /Auditing (p.481)

IRQ's (p.126)

NDIS/ODI (p.786,787)

Routers/Brouters (p.564)

Indentical MAC-addresses (reset them).

X.25 Advanced WAN Technology, very realiable in unstable situations. (p.595)
