Which Statement Describes A Characteristic Of A Wan?

Which statement describes a characteristic of a WAN?

• WAN works in the same geographics as the LAN but has the serials links.
• For the backbone of the campus, WAN gives the connectivity for the end-user.
• The services providers own the WAN networks.
• The WAN connection is considered by the serial links.

Answers: WAN can connect the LAN with the remote branch site LANs and the sites like telecommunication. The service provider owns the WAN networks, and the connection of WAN is made with a serials interface, not with all serial links that have a connection with WAN. The local network is responsible for the end user’s network connectivity in the organization.

What is the wide-area network (WAN)?

WAN stands for the wide-area network and it is the private geographical network that connects various local area networks. LAN is the network for the small group of the computer and many other devices and covers only a small distance, unlike the WAN. The connection which is established due to WAN is among the branch offices, headquarters of the companies, cloud services, and many other facilities. The device which connects the LAN with the WAN is the router, the WAN for companies gives the user access to share the application, services, and various centralized resources. The feature helps to reduce the cost because there is no need to install the same setup and the applications.

The restriction of the geographical area does not apply to the WAN, unlike the LAN. the LAN is set with different numbers of the area and has the connection with WAN which means WAN has not been restricted to any location. The reliable connectivity and the security of the WAN are provided by the virtual private network or VPN. for different use different VPNs is used. The IPsec VPN is for the open site-to-site connection between the branch and the main office For remote access by individual users, SSL VPN is essential because the data is encrypted over the WAN. Fiber optics is used for the connectivity of the WAN site and the performance, reliability, security of it are more than the VPN but for some of the organizations, it is costly.

How many types of WAN connections are present?

WAN consists of both the wired and the wireless connection. the wire connection of the WAN is described in the following:

• Multiprotocol Label Switching (MPLS).
• T1s
• Carrier Ethernet
• commercial broadband internet links

the types of wireless WAN are either the cellular data network as the 4G LTE and the WIFI or the satellite links in the network. The wired connection of the LAN is most preferable in most organizations but the wireless technology of the WAN as 4G LTE is increasing in today’s world.

Examples of the WAN:

Some of the examples of the WAN are given in the following sections:

• a network of the bank cash system.
• The network of the organization has several branches.
• The network of the school through the internet.
• WAN which is linked with the internet.
