converged

A ______________________network is capable of delivering voice, video, text, and graphics over the same communication channels.

easy to create lacks centralized administration less cost to implement

A company is contemplating whether to use a client/server or a peer-to-peer network. What are three characteristics of a peer-to-peer network?

data confidentiality

A network administrator is implementing a policy that requires strong, complex passwords. Which data protection goal does this policy support?

encapsulation

Applications on end devices generate data, alter data content, and are responsible for initiating the _______ process.

Internet

It provides connections through interconnected global networks

A, B, D, G*

Refer to the exhibit. Which set of devices contains only intermediary devices? A, B, D, G A, B, E, F C, D, G, I G, H, I, J

confidentiality

Requiring strong, complex passwords is a practice that supports which network security goal?

QoS.

The network provides predictable levels of service to different types of traffic supports this

intermediary devices

They direct data along alternate pathways when there is a link failure They filter the flow of data, based on security settings

end devices

They originate the data that flows through the network and are the interface between humans and the communication network

the distance the selected medium can successfully carry a signal the environment where the selected medium is to be installed Criteria for choosing a network medium are the distance the selected medium can successfully carry a signal, the environment in which the selected medium is to be installed, the amount of data and the speed at which the data must be transmitted, and the cost of the medium and its installation.

What two criteria are used to help select a network medium from various network media? (Choose two.) the types of data that need to be prioritized the cost of the end devices utilized in the network the distance the selected medium can successfully carry a signal* the number of intermediary devices installed in the network the environment where the selected medium is to be installed*

the distance the media can successfully carry a signal the environment where the media is to be installed

What two criteria are used to help select network media?

video conferencing

What type of network traffic requires QoS?

Congestion

Which expression accurately defines a state where the demand on the network resources exceeds the available capacity

Congestion

Which term describes the state of a network when the demand on the network resources exceeds the available capacity?

TelePresence

Which tool provides real-time video and audio communication over the Internet so that businesses can conduct corporate meetings with participants from several remote places

Cellular Satellite

Which two Internet connection options do not require that physical cables be run to the building?

DSL Cable

Which two Internet solutions provide an always-on, high-bandwidth connection to computers on a LAN?

DSL cable

Which two connection options provide an always-on, high-bandwidth Internet connection to computers in a LAN

Intermediary

_________ devices direct the path of the data and connect individual hosts to the network

Bandwidth

a measure of the data carrying capacity of the media

converged

a single network channel capable of delivering multiple communication forms

Intranet

a term used to refer to a private connection of LANs and WANs that belongs to an organization. is designed to be accessible only by the organization's members, employees, or others with authorization.

Powerline networking

adds the ability to connect a device to the network using an adapter wherever there is an electrical outlet.​ The network uses existing electrical wiring to send data. It is not a replacement for physical cabling, but it can add functionality in places where wireless access points cannot be used or cannot reach devices.​

Cloud computing

allows users to access applications, back up and store files, and perform tasks without needing additional software or servers. users access resources through subscription-based or pay-per-use services, in real time, using nothing more than a web browser.

LANs

are typically operated by single organizations or individuals.

WANs

are typically operated through multiple ISPs

Integrity

assurance that information not altered

Router

is used to determine the path that the messages should take through the network.

Confidentiality

only intended recipients can access

availability

timely and reliable access to data
