Answers to Questions 101-105 1 Answers to Questions 111-115

106. A company is opening a small branch office within the local dialing zone. They need 3 people to have access to the main computer to run the 32bit Windows version of Microsoft Office suite. It is not important for these users to be connected at all times, but they may need simultaneous access. The company's network hardware is centrally located with easy access to the company's PBX telephone system. Which remote solution would best suit these needs?

A. Remote Control

B. Remote Node

C. WinFrame or Terminal Server

D. VPN

& Domain 2.12: Define the functions of the following remote access protocols and services: RAS, PPP, PPTP, ICA.

107. Name two advantages of xDSL technology

A. Runs on fiber optic cables and increased bandwidth

B. Inexpensive and uses commonly available modems

C. Provides high speed digital access and is inexpensive

D. Provides fast digital service and "always on" Internet access

E. Widely available in rural areas for a modest cost

Explanation: The xDSL technology has many advantages that include: high speed all digital transfer rates, uses standard copper cabling, inexpensive, does not require a dedicated data line, and an "always-on" Internet connection.

& Domain 2.11: Identify the basic characteristics (e.g., speed capacity, Media) of the following WAN technologies: packet switching vs. circuit switching, ISDN, FDDI, ATM, frame relay, Sonet/SDH, T1/E1, T3/E3, Ocx.

108. Which dial-up protocol requires that devices on each end know the other's IP address?

A. SLIP

B. PPP

C. TCP/IP

D. POTS

E. xDSL

Explanation: Serial Line IP (SLIP) lacks addressing, packet type identification, or error detection/correction. Both computers using a SLIP link need to know each other's IP address for routing purposes.

& Domain 2.12: Define the functions of the following remote access protocols and services: RAS, PPP, PPTP, ICA.

109. What are some advantages of ISDN?

A. Both data and voice can be carried over the connection at the same time

B. Can use existing copper wires within a building

C. Inexpensive

D. Widely available

E. Generally accepted as an Industry Standard

Explanation: While ISDN is less expensive than some other digital connections, it is still more expensive than POTS (plain old telephone service) or DSL (digital subscriber line). Availability is sometimes questionable, and it has not been generally accepted as an industry standard.

& Domain 2.11: Identify the basic characteristics (e.g., speed capacity, Media) of the following WAN technologies: packet switching vs. circuit switching, ISDN, FDDI, ATM, frame relay, Sonet/SDH, T1/E1, T3/E3, Ocx.

110. From the choices below, select the properties of SLIP:

A. Capable of supporting multiple transport protocols

B. Capable of supporting only IP

C. Supports dynamic re-negotiation of line speeds

D. May acquire a dynamic IP address using DHCP

E. SLIP is the latest protocol replacing PPTP

Explanation: Serial Line Internet Protocol (SLIP) was the first protocol designed for the TCP/IP suite to allow remote access. While SLIP has less overhead, and thereby consumes fewer resources than PPP, it is more difficult to configure. The only protocol SLIP supports is IP. Once a connection is established at a given speed, it cannot be changed. When configuring SLIP the host must be pre-configured with an IP address.

& Domain 2.12: Define the functions of the following remote access protocols and services: RAS, PPP, PPTP, ICA.
