Explicación:

1. 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?

private dedicated lines through their local service provider

a dialup connection that is supplied by their local telephone service provider

Virtual Private Networks that would enable the company to connect easily and securely with employees

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.

2. Which network scenario will require the use of a WAN?

Employees need to connect to the corporate email server through a VPN while traveling.*

Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network.

Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building.

Employee workstations need to obtain dynamically assigned IP addresses.

When traveling employees need to connect to a corporate email server through a WAN connection, the VPN will create a secure tunnel between an employee laptop and the corporate network over the WAN connection. Obtaining dynamic IP addresses through DHCP is a function of LAN communication. Sharing files among separate buildings on a corporate campus is accomplished through the LAN infrastructure. A DMZ is a protected network inside the corporate LAN infrastructure.

3. Which statement describes a characteristic of a WAN?

A WAN operates within the same geographic scope of a LAN, but has serial links.

A WAN provides end-user network connectivity to the campus backbone.

WAN networks are owned by service providers.*

All serial links are considered WAN connections.

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.

4. What are two common types of circuit-switched WAN technologies? (Choose two.)

ISDN*

DSL

PSTN*

ATM

Frame Relay
