1 What happens when a device is disconnected from the middle of a BUS network?

The hub will propagate error messages to the rest of the network

All devices on the network will fail

The Server will stop responding to that device

Data will not be able to get to devices on the other side of this device

If a bridge is on the network, only that segment will be effected

2 Why is there a limit to the number of MAUs that can be connected together in a standard Token-ring network?

Too many MAUs would exceed the cable limits imposed by the Token Ring specification

Too many MAUs would create to large of a collision domain for communications to take place

Too many MAUs require more electricity than the devices can support

Too many devices connected through MAUs requires more time to get control of the token that communications becomes unacceptable

There is no limit to the number of MAUs a token ring network can support

3 How many devices can communicate simultaneously within a Token-ring LAN?

One for each MAU on the LAN

One

Two

As many devices as the administrator defines within the NOS

Between 1 and 5 if the ring speed is 16mbp/s

PCI or ISA slot

IRQ setting

DMA Address

12 What are the two methods switching hubs use to transport data between devices?

Routing

Forwarding

Cut-through

Active

Store-and-forward

13 What happens when a device is disconnected from the middle of a BUS network?

The hub will propagate error messages to the rest of the network

All devices on the network will fail

The Server will stop responding to that device

Data will not be able to get to devices on the other side of this device

If a bridge is on the network, only that segment will be effected

14 What are some advantages of a Client/Server network over a Peer-to-Peer network?

Performance is better on a Peer-to-Peer

Security is better on a Client/Server

Performance is better on a Client/Server

Security is better on a Peer-to-Peer

Client/Server is easier to administrate
