guide.
A small company with 10 employees uses a single LAN to share information between
computers. Which type of connection to the Internet would be appropriate for this
company? - Answer a broadband service, such as DSL, through their local service
provider
For this small office, an appropriate connection to the Internet would be through a
common broadband service called Digital Subscriber Line (DSL), available from their
local telephone service provider. With so few employees, bandwidth is not a significant
problem. If the company were bigger, with branch offices in remote sites, private lines
would be more appropriate. Virtual Private Networks would be used if the company had
employees who needed to connect to the company via Internet.
Which statement describes a characteristic of a WAN? - Answer WAN networks are
owned by service providers.
WANs are used to interconnect the enterprise LAN to remote branch site LANs and
telecommuter sites. A WAN is owned by a service provider. Although WAN connections
are typically made through serial interfaces, not all serial links are connected to a WAN.
LANs, not WANs, provide end-user network connectivity in an organization.

DSL

switched telephone network (PSTN) and the integrated services digital network (ISDN).
Frame Relay and ATM are packet-switched WAN technologies. DSL is a WAN
technology that offers broadband Internet access.
What is a requirement of a connectionless packet-switched network? - Answer Full
addressing information must be carried in each data packet.
A connection-oriented system predetermines the network path, creates a virtual circuit
for the duration of the packet delivery, and requires that each packet only carry an
identifier. A connectionless packet-switched network, such as the Internet, requires
each data packet to carry addressing information.
A new corporation needs a data network that must meet certain requirements. The
network must provide a low cost connection to sales people dispersed over a large
geographical area. Which two types of WAN infrastructure would meet the
requirements? (Choose two.) - Answer Internet
