Question 1

With BitTorrent,as more computers request the file,they become part of a ____ that uses peer-to-peer technology to exchange file pieces with each other.
A) swarm
B) seed
C) leech
D) choker

Accepted Answer

A BitTorrent swarm is a group of peers (computers) that are downloading and uploading the same file using the BitTorrent protocol. The swarm is formed as more computers join in to request the file, and they exchange file pieces with each other using peer-to-peer technology. "Seed" refers to a computer that has the complete file and is only uploading to others, while "leech" refers to a peer that only downloads and doesn't upload much, and "choker" is a technical term in the BitTorrent protocol for a mechanism that limits the number of connections a peer can have. None of these terms fully fit the given description as well as "swarm."

Question 2

Accepted Answer

The average "survival time" for an unprotected computer to remain uncompromised is only nine minutes, due to the high frequency of automated attacks and vulnerabilities.

Question 3

A ____ IP address is one which can be accessed by packets on the Internet.

B) dynamic
C) routable
D) private

Accepted Answer

A routable IP address is one which can be accessed by packets on the Internet. Static and dynamic refer to the method of assigning IP addresses, and private IP addresses cannot be accessed directly over the Internet.

Question 4

-The accompanying figure represents a virtual private network.In this figure,C points to a(n)____ server.
A) unencrypted
B) VPN
C) public
D) channel

Accepted Answer

In a virtual private network (VPN) setup, the letter C typically points to the VPN server, which is responsible for encrypting and decrypting data as it passes between the user's device and the internet.

Question 5

Sharing files on a LAN or the Internet requires open ____.
A) ports
B) domains
C) sources
D) channels

Accepted Answer

To share files on a LAN or the Internet, open ports are necessary as they provide access points for incoming and outgoing data. These ports act as gateways for the transfer of data between devices on the network or over the Internet. Without open ports, file sharing would not be possible, as the data would be unable to flow through the network.

Question 6

Messaging and chat protocols include all of the following EXCEPT ____.
A) IRC
B) MSNP
C) Jabber
D) Talkie

Accepted Answer

Out of the given options, IRC, MSNP, and Jabber are all messaging and chat protocols, while Talkie is not.

Question 7

The ____ protocol allows the transfer of files from one computer to another over any TCP/IP network.
A) ftp
B) http
C) P2P
D) GRID

Accepted Answer

The FTP (File Transfer Protocol) allows the transfer of files over any TCP/IP network, such as the Internet. It is one of the oldest and most common protocols used for file transfer.

Question 8

-The accompanying figure is a screenshot of FileZilla,in which the ____ file will go to the location pointed to by box B.
A) downloaded
B) uploaded
C) redirected
D) remastered

Accepted Answer

The file in FileZilla will be uploaded to the location pointed to by box B, as FileZilla is an FTP client used for transferring files from a local computer to a remote server.

Question 9

The use of automated software to locate computers that are vulnerable to unauthorized access is a port ____.
A) search
B) probe
C) dig
D) pry

Accepted Answer

The use of automated software to locate vulnerable computers is called port probing. It involves scanning a range of ports to identify which ones are open and therefore vulnerable to attack. The term "port search" does not accurately describe this process, while "dig" and "pry" are not commonly used terms in this context.

Question 10

VoIP systems are offered by companies such as ____.
A) AT&T
B) magicJack
C) Vonage
D) all of the above

Question 12

____ are intended to work within LANs to monitor and direct packets being transported from one device to another.
A) Routers
B) Gateways
C) Filters
D) Firewalls

Accepted Answer

Routers are networking devices that are designed to manage and direct packets of data as they travel between different devices and networks. They are specifically created to work within local area networks (LANs) and are responsible for sending packets of data to their intended destination. They accomplish this by maintaining a table of available routes and selecting the best path to direct each packet based on factors like network congestion, packet size, and other relevant information. Routers are an essential component of modern network infrastructure, enabling devices to communicate efficiently and securely within a LAN environment.

Question 13

A) uploaded
B) downloaded
C) reloaded
D) remastered

Accepted Answer

Box A in FileZilla typically indicates files on the local system that are to be uploaded to a remote server.

Question 15

-The accompanying figure represents a virtual private network.In this figure,A points to ____ data.
A) encrypted
B) remote
C) routed
D) nonencrypted

Accepted Answer

The term "encrypted" refers to data that has been converted into a secure format to prevent unauthorized access. In a virtual private network (VPN), data is typically encrypted to ensure privacy and security during transmission.

Question 16

Network services such as the Web,ftp,and e-mail operate from ____.
A) routers
B) gateways
C) ports
D) portals

Accepted Answer

Network services such as the Web, FTP, and e-mail operate from specific ports, which are standardized endpoint locations used in communications protocols. Routers and gateways facilitate the transfer of data between networks, while portals are websites that provide access to various services and resources.

Question 17

BitTorrent can be used to distribute ____.
A) spyware
B) adware
C) malicious code
D) all of the above

Accepted Answer

BitTorrent is a peer-to-peer file sharing protocol that can be used to distribute any type of digital content, including spyware, adware, and malicious code, if users choose to share such files.

Question 18

VoIP software is sometimes referred to as a(n)____ client.
A) ISP
B) SIP
C) HTTP
D) none of these

Accepted Answer

VoIP software typically uses the SIP (Session Initiation Protocol) protocol to establish, modify, and terminate voice and video calls over the internet. Therefore, VoIP software can be referred to as a SIP client. A is incorrect because ISP (Internet Service Provider) refers to the company providing internet access, not the software used for VoIP. C is incorrect because HTTP (Hypertext Transfer Protocol) is used for web browsing, not VoIP. D is incorrect because there is a specific term for VoIP software client, which is SIP client.
