Which of the following are...

Question 2

A(n) ____ server is a computer or software application that hides an internal IP address from the outside world by substituting its own IP address for a source computer's IP address before sending outgoing email or webpage requests.

Accepted Answer

A proxy server is designed to act as an intermediary between a client or user and other servers, such as a mail server or web server. It can help to ensure security and privacy by hiding the user's IP address and masking their online activities, which is important for businesses and individuals who want to keep their data and personal information safe. While mail servers, HTTP servers, and FTP servers are all types of servers, they do not necessarily perform the same functions as a proxy server.

Question 3

Modified Multiple Choice
Internet telephony is also called _____.

Accepted Answer

Internet telephony is also known as IP telephony or Voice over Internet Protocol (VoIP). Option A is incorrect because VPN (Virtual Private Network) is a technology used to create a secure connection over the internet. Option D is incorrect because teleconferencing refers to a virtual meeting between two or more participants using audio, video, or text communication.

Question 4

Question 5

A(n) ____ is the combination of organizations or individuals sending and receiving encrypted data, their public and private keys, and the CAs that issue the keys and digital certificates.

Accepted Answer

Public Key Infrastructure (PKI) is a system that manages the creation, distribution, and revocation of digital certificates. It is a combination of organizations or individuals sending and receiving encrypted data, their public and private keys, and the Certificate Authorities (CAs) that issue the keys and digital certificates. A VPN (Choice B) is a virtual private network that provides a secure connection between two points over the internet. A private peering agreement (Choice A) is an agreement between two organizations to directly interconnect their networks to exchange traffic. An NSP (Choice D) is a Network Service Provider that provides internet connectivity and other network-related services.

Question 6

The ability of a(n) _________________________ LAN to support shared data storage, provide network maintenance tools, and promote more efficient data backups offers advantages over a peer-to-peer LAN.

Accepted Answer

The answer of The ability of a(n) _________________________ LAN to...

Question 7

A network's _________________________ method specifies how data travels from node to node across the network.

Accepted Answer

The answer of A network's _________________________ method specifies how data...

Question 8

A(n) ____ private network uses tunneling to hide encrypted data, IP addresses, and a tunneling protocol inside IP packets routed over the public network using the IP protocol.

Accepted Answer

The description fits a virtual private network (VPN), which uses tunneling to create a private network over a public one. The other options are not complete enough or do not fit the description.

Question 9

When an organization wants to use encryption, it requests a set of associated public and private keys from a ____.

Accepted Answer

The organization would request a set of public and private keys from a certification authority (CA) in order to use encryption. The CA is responsible for verifying the identity of the organization and issuing digital certificates that contain the public key. This allows recipients of encrypted messages to use the public key to decrypt the message and confirm the identity of the sender.

Question 10

An organization may outgrow a(n) _________________________ LAN quickly, as more computers and devices need to be added or file- and device-sharing becomes more complex.

Accepted Answer

The answer of An organization may outgrow a(n) _________________________ LAN...

Question 11

Virus protection ____ and apps require continual updates with information on recently discovered viruses.

Accepted Answer

Virus protection software and apps are designed to provide protection against viruses and require frequent updates to stay up to date and effective in detecting and removing newly discovered viruses. Manuals and presentations do not have the ability to provide real-time virus protection or updates, while hardware does not have a direct connection to virus protection.

Question 12

A network ____ is a combination of hardware and software that filters traffic between private networks or between a private network and a public network, such as the Internet.

Accepted Answer

A firewall is a combination of hardware and software that filters traffic between private networks or between a private network and a public network, such as the Internet. A cable is not a network device, it is a physical component used to connect network devices. A hub is a networking device that connects multiple devices together into a single network segment. A data switch is a device that connects multiple devices together and forwards data packets between them. While data switches can provide some level of filtering, they are not specifically designed for network security like a firewall.

Question 13

False warnings about viruses are called virus ____.

Accepted Answer

False warnings about viruses are intentionally created and spread through various means, such as email or social media, to cause panic or harm. These false warnings are known as virus hoaxes. Choices A, B, and D do not accurately describe false virus warnings.

Question 14

Question 16

Network administrators and IT managers use network ____ to expose network vulnerabilities.

Accepted Answer

Network administrators and IT managers use security audits to expose network vulnerabilities. A security audit is a procedure that analyzes the security of a network or system by evaluating its strengths and weaknesses. Through security audits, vulnerabilities can be identified and addressed before they are exploited by potential attackers.

Question 17

A(n) _________________________ is an internal expansion card that enables a computer or other device to access a network.

Accepted Answer

The answer of A(n) _________________________ is an internal expansion card...

Question 18

Modified Multiple Choice
Which of the following are examples of services used in holding virtual conversations?

Accepted Answer

Google Hangouts and FaceTime are both examples of services used in holding virtual conversations, while Foursquare and Network Solutions are not.

Question 19

A(n) ____ electronically authenticates an organization's or individual's identity.

Accepted Answer

A digital certificate is a way to electronically authenticate the identity of an organization or individual. It is a digital file that contains information about the identity of the certificate holder and is issued by a trusted third party known as a certificate authority (CA). The certificate is used to verify the identity of the certificate holder when communicating over a network, such as the internet. It is commonly used in secure websites (HTTPS), email encryption and digital signatures, and other secure online transactions.

Question 20

____ involves security audit personnel trying to hack into a network.

Accepted Answer

Penetration testing involves security professionals attempting to exploit vulnerabilities in a network to identify and fix security weaknesses.
