a. Distributed Routing

Front 10

4. What is the primary advantage of distributed routing?

Back 10

a. No single node is responsible for maintaining a central routing table
b. If any node crashes, it will probably not disable entire network
c. A node will not need to send a request to a central table, since each node has its own table.

Front 11

5. What is the subnet responsible for?

Back 11

a. For getting the data to the proper destination node, which then delivers it to the appropriate destination station.

Front 12

6. What is the primary advantage of using centralized routing?

Back 12

a. Is that all routing information is kept at one node or site.
b. Minimize routing table storage
c. Eliminates multiple tables having conflict data.

Front 13

7. What is the major disadvantage of having centralized routing

Back 13

is putting all your eggs in one basket syndrome

Front 14

Causes of congestion on the network

Back 14

communication links
node failures
Insufficient buffer space at a node in a subnet can also cause network congestion

Front 15

The term "frame" is used at what layer of the OSI model (packet switched)

Back 15

Data link layer

Front 16

The term "packet" is used at what layer of the OSI model (packet switched)

Back 16

network layer

Front 17

The physcal network design of a wide area network, or its subnet has three basic forms

Back 17

circuit-switched, packet-switched, and broadcast

Front 18

An alternated solution to controlling the flow of packest betwee n two nodes is ____

Back 18

buffer preallocation

Front 19

explain buffer preallocation

Back 19

before one node sends a series o packets to another node, it first check with receiving node to find if it has enough buffer space for N packets.

Front 20

How do solve the problem of congestion between node and station

Back 20

choke packet
or permit system when the it limits the number of packets a station could send.

Front 21

What is the only technology that successfully supports Quality of Service?

Back 21

ATM ( asynchronous transfer mode)

Front 22

A Local Area Network is a _________
subnet

Back 22

broadcast

Hint 22

One of the three subnets

Paremeters used by network users and the network to establish minimum guidelines for proper transfer of data. these guide lines inlude transmission speed, level or errors, and overqall network thoughput

Back 23

QOS Quality of Service

Front 24

What is a virtual circuit packet-switched subnet

Back 24

All packets that belong to a logical connection can followe the same path though the network.

Front 25

What is cicuit-switched subnet

Back 25

in which a dedicated cicuit is established between sender and receiver, all data passes over this circuit.

Front 26

What is an example of a circuit switched subnet

Back 26

dialup telephone system.

Front 27

What is the main responsibility of the internet protocol?

Back 27

provides a connectionless data transfer over heterogeneous networks by passing and routing IP datagrams

Front 28

What is another name for datagrams

Back 28

data packets

Front 29

The main responsibilty for Transmission Control Protocol

Back 29

is to turn an unreliable sub-network into a reliable network that does not lose or duplicate packets

Front 30

IP header contains information that the router needs. What is the information that the router needs

Back 30

address information, datagram sixe, and the time the datagram was created. This information is applied to transport packet and the internet network layer

Front 31

When a router has the IP datagram, it may make several decisions affecting the future of the datagram. The router

Back 31

makes routing decisions based on the address portion of the IP datagram
