Answers to Questions 111-115

111. You have been instructed to install remote access on an NT server to support Unix users at a remote site. To accomplish this you will install and configure on the NT server which items?

A. WINS

B. TCP/IP

C. Switch

D. PING

E. RAS

Explanation: The only protocol available to Unix users is TCP/IP. To support remote connections so users have access to the network as if they were on the LAN locally, RAS (Remote Access Service) must be installed on the NT server. A switch connects computers on a LAN by MAC address, and therefore is of no help to remote Unix users. PING uses ICMP to confirmed connectivity, and is generally only used as a troubleshooting tool.

& Domain 2.5: Define the purpose, function and/or use of the following protocols within TCP/IP: IP, TCP, UDP, FTP, TFTP, SMTP, HTTP, HTTPS, POP3/IMAP4, Telnet, ICMP, ARP, NTP.

& Domain 3.7: Given a remote connectivity scenario (e.g., IP, IPX, dial-up, PPPoE, authentication, physical connectivity etc.), configure the connection.


 

112. Real-time data is best sent using:

A. circuit switching.

B. packet switching

C. Ethernet switching

D. Optical switching

E. Amplified switching

Explanation: Circuit switching creates a connection that remains until terminated. This is best for data that can not tolerate delays.

& 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.


 

113. Your customer has a number of salespeople that need access to the company inventory files. The data is accessed through a spreadsheet program that is loaded on each their laptops. Which is the best remote access method to deploy?

A. Remote Wizard

B. Remote Node

C. VPN

Explanation: Remote Node fits this situation best since the spreadsheet program is located on each of the laptops. Also, a dial-up connection would be simple to install and configure and would provide good transfer speeds.

& Domain 3.7: Given a remote connectivity scenario (e.g., IP, IPX, dial-up, PPPoE, authentication, physical connectivity etc.), configure the connection.


 

114. Which of the following are advantages of PSTN (POTS)? (Choose three)

A. PSTN is readily available.

B. PSTN is inexpensive to implement.

C. PSTN supports TDR

D. PSTN supports data ranges greater than 64 Kbps.

E. PSTN is easy to configure.

Explanation: PSTN is your local telephone access service and is therefore readily available. Because of this, it is inexpensive to implement as well. Because of its simplicity, it is also easy to configure.

A Time Domain Reflectometer (TDR) can be used to pinpoint cabling problems, but doesn't have any significance to this question.

& Domain 3.7: Given a remote connectivity scenario (e.g., IP, IPX, dial-up, PPPoE, authentication, physical connectivity etc.), configure the connection.

& Domain 4.2: Given a troubleshooting scenario involving a small Office/Home Office network failure (e.g., xDSL, cable, home satellite, wireless, POTS) identify the cause the problem.


 

115. What is the standard IRQ for COM 1 and COM 4?

A. COM 1 = IRQ 1
COM 4 = IRQ 4

B. Both use Com 4

C. Both use Com 3

D. COM 1 = IRQ 4
COM 4 = IRQ 3

E. COM 1 = IRQ 3
COM 4 = IRQ 2

Explanation: The standard IRQs: COM 1 = IRQ 4, and COM 4 = IRQ 3.

& Domain 4.2: Given a troubleshooting scenario involving a small Office/Home Office network failure (e.g., xDSL, cable, home satellite, wireless, POTS) identify the cause the problem.

& Domain 4.3: Given a troubleshooting scenario involving a remote connectivity problem (e.g., authentication failure, Protocol configuration, physical connectivity) identify the cause a problem.

& Domain 4.9: Given a network problem scenario, select an appropriate course of action based on general troubleshooting strategy.

& Domain 4.11: Given a network to allow sharing scenario involving a client connectivity problem (e.g., incorrect Protocol/client software/authentication configuration, or insufficient rights/permission), identify the cause the problem.

& Domain 4.12: Given a network-troubleshooting scenario involving a wiring/infrastructure problem, identify the cause of the problem(e.g., bad media, interference, network hardware).
