Question 1

At what core layer do you find WAN standards?
A) Single-network
B) Internet
C) Application
D) None of the above.

Accepted Answer

A

Question 2

Intercepting wireless LAN transmissions is difficult.

Accepted Answer

Intercepting wireless LAN transmissions can be relatively easy with the right tools and knowledge, as wireless signals are broadcast through the air and can be captured by anyone within range using a wireless network interface controller (NIC) in monitor mode and software designed for sniffing wireless traffic.

Question 3

The organization that funded the creation of the Internet is ________.
A) the IETF
B) ISO
C) DARPA
D) the National Science Foundation

Accepted Answer

DARPA (Defense Advanced Research Projects Agency) funded the creation of the Internet in the 1960s as a means of secure communication for the U.S. military.

Question 4

In this book, when internet is spelled with a capital I, it means the global Internet.

Accepted Answer

This is stated in the question stem.

Question 5

If two hosts are separated by seven networks, how many packets will there be along the way when a host transmits a packet to another host?
A) 1
B) 2
C) 7
D) 14

Accepted Answer

The number of packets transmitted does not increase with the number of networks they pass through. A single packet can traverse multiple networks to reach its destination.

Question 6

Single-network core standards are for message delivery through ________.
A) LANs
B) WANs
C) Both A and B
D) Neither A nor B

Accepted Answer

Single-network core standards are designed for message delivery through both Local Area Networks (LANs) and Wide Area Networks (WANs).

Question 7

User computers connect to ________ switches.
A) core
B) primary
C) workgroup
D) terminal

Accepted Answer

Workgroup switches are used to connect user devices such as computers, printers, and other peripherals within a small office or departmental network. Core switches are used to connect multiple workgroup switches and tend to be larger and more expensive. Primary and terminal switches are not common network switch categories.

Question 8

Attackers can read signals traveling over UTP without tapping the cord.

Accepted Answer

This is true. Attackers can use techniques such as electromagnetic radiation or power analysis to intercept signals traveling over unshielded twisted pair (UTP) cables without the need to physically tap into the cord. This is why it's important to use encryption and other security measures to protect data traveling over UTP.

Question 9

The terms octet and byte mean the same thing.

Accepted Answer

The terms octet and byte both refer to a group of 8 bits, so they mean the same thing.

Question 10

Packets are carried inside frames.

Accepted Answer

Packets are encapsulated in frames which provide the necessary information for their transmission and reception across a network.

Question 11

If two hosts are separated by five networks, how many frames will there be along the way when a host transmits a packet to another host?
A) 1
B) 2
C) 5
D) 10

Accepted Answer

Each network will act as a point where the frame will need to be processed and passed on to the next network. Therefore, there will be a total of 5 frames transmitted along the way.

Question 12

A device attached to a network is called a ________.
A) client
B) server
C) host
D) Neither A nor B

Accepted Answer

A device attached to a network can be a client or a server, but it is always considered a host. Therefore, option C is the best choice.

Question 13

A residential access router usually contains ________.
A) a DHCP server
B) an Ethernet switch
C) Both A and B
D) Neither A nor B

Accepted Answer

A residential access router typically contains both a DHCP server and an Ethernet switch. The DHCP server provides IP addresses to devices on the local network, while the Ethernet switch allows multiple devices to connect to the router and communicate with each other. Additionally, a residential access router may also include features like wireless connectivity, firewalls, and Quality of Service (QoS) settings to prioritize network traffic.

Question 14

A network that runs on the customer premises is a ________.
A) LAN
B) WAN
C) Both A and B
D) Neither A nor B

Accepted Answer

A network that runs on the customer premises is called a Local Area Network (LAN). LANs are used for connecting devices within a limited area, such as a home, office, or school building. Wide Area Networks (WANs), on the other hand, connect devices over a larger distance, such as across multiple cities or countries. Therefore, choice A is the best answer as it accurately describes a network that runs on the customer premises.

Question 15

Security problems with protocols include ________.
A) a lack of security in earlier versions
B) awkwardly added security
C) Both A and B
D) Neither A nor B

Accepted Answer

Security problems with protocols can stem from both a lack of security in earlier versions and awkwardly added security measures. This is why it is important to constantly review and improve protocols to ensure they are as secure as possible.

Question 16

Companies use carriers for WAN transmission because ________.
A) companies lack rights of way
B) carriers have extremely strong security
C) Both A and B
D) Neither A nor B

Accepted Answer

Companies use carriers for WAN transmission because they lack the rights-of-way for laying the required cables or fiber-optic lines for their own private networks.

Question 17

Frames are messages traveling through ________.
A) LANs
B) WANs
C) Both A and B
D) Neither A nor B

Accepted Answer

The answer of Frames are messages traveling through ________.
A) LANs
B)...

Question 18

When your mobile phone is on a network, it is a host.

Accepted Answer

When a mobile phone is connected to a network, it becomes a host device, as it is capable of sending and receiving data on the network.

Question 19

When your home PC is on a network, it is a host.

Accepted Answer

A PC on a network is identified as a host, as it is capable of providing resources and services to other devices on the same network.

Question 20

In internets, different networks are connected by ________.
A) switches
B) routers
C) Both A and B
D) Neither A nor B

Accepted Answer

Routers are used to connect different networks in the internets. Switches are used to connect devices within the same network. Therefore, option B is the correct answer.
