Deck 8: Internet Operation

Question 1

The Internet and the Internet Protocol is designed to provide differentiated services depending on whether traffic is elastic or inelastic.

Answer 1

False

Question 2

Two notable consumer electronic gadgets that are impacting the traffic load on networks are the digital versatile disc and the digital still camera.

Answer 2

True

Question 3

Give one example of an Internet application with elastic traffic,and one of an application with inelastic traffic.

Answer 3

Elastic: E-mail,push news
Inelastic: Video conferencing,financial transactions

Question 4

The source and destination address fields in the TCP header each contain a 32-bit Internet address.

Question 5

A digital versatile disc can store approximately 100 times more data than a CD-ROM.

Question 6

A QoS facility allows the Internet to treat all classes of traffic equally in order to optimize the services provided to all users.

Question 7

The left-most bits of a IP address determine whether it is Class A,B,or C.

Question 8

An internet routing protocol is used to exchange information about reachability and traffic delays,allowing each router to construct a next-hop routing table for paths through the internet.

Question 9

Which of the following describes class A networks?

A)Many networks,each with a few hosts
B)Medium number of networks,each with a medium number of hosts
C)Few networks,each with many hosts
D)A dedicated network,with a set number of hosts
E)A network dedicated to multicast applications

Question 10

Typically,more complex routing protocols are used between autonomous systems within a larger internet and relatively simple routing protocols are used within each autonomous system.

Question 11

Most IP addresses consist of a network identification and a host identification within that network.

Question 12

Which of the following describes class C networks?

A)Many networks,each with a few hosts
B)Medium number of networks,each with a medium number of hosts
C)Few networks,each with many hosts
D)A dedicated network,with a set number of hosts
E)A network dedicated to multicast applications

Question 13

What is a subnet mask?

Question 14

The maximum number of Class A network addresses is

A)16
B)126
C)128
D)256
E)16,384

Question 15

Which of the following describes class B networks?

A)Many networks,each with a few hosts
B)Medium number of networks,each with a medium number of hosts
C)Few networks,each with many hosts
D)A dedicated network,with a set number of hosts
E)A network dedicated to multicast applications

Question 16

Subnets are used where the number of networks exceeds the number of hosts within a specific company or organization.
