Which Statement Correctly Describes a WAN Technology?

A wide area network (WAN) is a computer network that covers a large geographical area. WANs are often used to connect smaller networks, such as local area networks (LANs), together.

WAN Technologies

There are many different types of WAN technologies available, each with its own advantages and disadvantages. Which statement correctly describes a WAN technology?

A) A WAN technology is any technology that allows two or more devices to communicate with each other over a wide area.

B) A WAN technology uses a network of computers to connect different geographical areas.

C) A WAN technology uses a variety of media to connect different geographical areas.

The correct answer is A.

WAN Components

WAN technologies use a variety of components to provide connectivity over long distances. These components include routers, switches, repeaters, and bridges. Routers are the most commonly used WAN devices and are responsible for routing traffic between different networks. Switches are used to connect two or more networks together and can be used to create virtual LANs. Repeaters amplify signals and regenerate data packets that have been damaged or lost in transit. Bridges are used to connect two or more LANs together and can also be used to filter traffic between networks.

WAN Connections

A WAN, or Wide Area Network, is a large and often complex telecommunication network that covers a large geographic area, such as a city, state, or country. WAN technologies connect multiple LANs, or Local Area Networks, together. The most common type of WAN technology is the Internet, which connects LANs all over the world.

WAN Services

Wide Area Networks (WANs) are used to connect Local Area Networks (LANs) together, usually over long distances. WANs can be implemented using a variety of technologies, including:
-T1/E1 lines
-T3/E3 lines
-Synchronous Optical Network (SONET)/Synchronous Digital Hierarchy (SDH)
-Satellite
-Frame Relay

WAN Protocols

There are a variety of Wide Area Networking (WAN) technologies available, each with its own strengths and weaknesses. The most common protocols are:

-Ethernet: A tried-and-true technology that is both fast and reliable.
-DSL: A high-speed technology that is widely available but can be expensive.
-Cable: A high-speed technology that is widely available but can be expensi

WAN Implementation

A wide area network, or WAN, is a data network that spans a large geographic area. The term WAN can refer to the interconnection of multiple LANs over a wide area. A WAN often uses public switched telephone lines, leased lines, satellites, or wireless data links.

WAN Management

A WAN is a network that spans a large geographical area, such as a country or the world. WANs are used to connect LANs and other types of networks together so that they can communicate with each other. WANs are typically owned by large organizations, such as telecommunications companies, large corporations, or government agencies.

WAN Security

A WAN can be secure in different ways. One way is to have a VPN Concentrator at each site. This will encrypt all traffic that goes across the WAN. Another way is to use Multiprotocol Label Switching (MPLS). This will segregate traffic so that only certain types of traffic can go across the WAN.

WAN Troubleshooting

A WAN is a computer network that covers a wide area. Most WANs are not owned by a single organization but rather span multiple organizations. These networks are usually slower and more expensive than LANs because they must connect disparate systems over long distances. WAN technologies include leased lines, Frame Relay, and ATM.

WAN Best Practices

There is no one-size-fits-all answer to this question, as the best WAN technology for your organization will depend on a number of factors, including budget, geographical location, and desired features. However, some general best practices for choosing a WAN technology include considering cost-effective solutions that can scale to meet future needs, seeking out vendors with a good reputation for customer service and support, and ensuring that the chosen solution is compatible with existing infrastructure.
