Term
| What are two differences between LANs and WANs? |
|
Definition
While a LAN connects computers, peripherals, and other devices in a single building or other geographical area, a WAN transmits data across broad geographic distances.
A LAN transmits data faster than a WAN. |

Term
| Give 3 statements that are considerations for DSL: |
|
Definition
DSL service can be incrementally added in any area
DSL is not universally available in all geographic locations
DSL has distance limitations |
|
|
Term
| At which OSI level do WAN protocols define encapsulation of data for transmission toward a remote location and mechanisms for transferring the resulting frames? |
|
Definition
|
|
Term
| Which three statements describe the function of PPP? |
|
Definition
The LCP in PPP is used for establishment, configuration, and testing the data-link connection.
PPP originally emerged as an encapsulation protocol for transporting IP traffic over point-to-point links.
PPP provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. |

Term
| Which statement most accurately describes static and dynamic routes? |
|
Definition
| Static routes are manually configured by a network administrator, whereas dynamic routes are automatically learned and adjusted by a routing protocol. |

|
Term
| Which three statements accurately describe the characteristics and functions of circuit-switched networks? |
|
Definition
ISDN is an example of circuit-switched network.
Circuit switching allows multiple sites to connect to the switched network of a carrier and communicate with each other.
With circuit switching, a dedicated physical circuit is established, maintained, and terminated through a carrier network for each communication session. |

Term
| Give three statements that accurately describe DSL: |
|
Definition
DSL technology is a circuit-switched connection technology that uses existing twisted-pair telephone lines to transport high-bandwidth data, such as multimedia and video, to service subscribers.
DSL technologies place upload and download data transmissions at frequencies above a 4-kHz window, allowing both voice and data transmissions to occur simultaneously on a DSL service.
DSL technology allows use of the local-loop line for normal telephone voice connection and an always-on connection for instant network connectivity. |

Term
| Give three statements that describe the function of HDLC? |
|
Definition
HDLC includes support for both point-to-point and multipoint configurations.
HDLC includes a method for authentication.
HDLC specifies an encapsulation method for data on synchronous serial data links using frame character and checksum. |

Term
| The output of which command displays the active translations for a NAT translation table? |
|
Definition
|
|
Term
| Give three statements that accurately describe WANs: |
|
Definition
WANs use serial connections of various types to provide access to bandwidth.
WANs use the services of carriers such as telephone companies, cable companies, satellite systems, and network providers.
WANs connect devices that are separated by wide geographic areas. |
