Answers

1.

Correct Answer = C

If a single computer on your network cannot communicate with other systems on the same network, it is probable that its IP address is invalid or the system has not received an IP address from a DHCP server, which hands out IP addresses randomly on the network.

2.

Correct Answer = D

In order for two computers to communicate, they must have a common language or set of rules known as a protocol. Binary conversion is a process used to convert binary numbers to decimal numbers to binary. IPCONFIG /ALL is a TCP/IP command used to display TCP/IP configuration settings.

3.

Correct Answers = A and C

A loopback plug or analog loopback adapter can be used to test the integrity of a modem. A digital multimeter is used to troubleshoot system power-related issues. A small brush and compressed air are used to clean a system unit.

4.

Correct Answer = D

In order to communicate with your Ethernet network, you would need to install and configure a NIC card with associated software drivers.

5.

Correct Answer = C

If you get this question wrong, please start reading this book from page one again. ALWAYS VIRUS SCAN ANY PROGRAMS YOU DOWNLOAD FROM THE INTERNET!

6.

Correct Answers = A and C

Most computer viruses arrive through a borrowed floppy or other removable media disk or the Internet.

7.

Correct Answers = A, B, and C

Answers A, B, and C are valid choices. If the entire network were affected by RFI, you would have problems with more than one user. A network hub or switch is used to connect several computers together on a network. If the hub or switches were powered off, all users on that particular network would be affected.

8.

Correct Answers = A, B, and D

Ethernet, Token Ring, and modem connections can all be configured to use TCP/IP.

9.

Correct Answers = A, C, and D

You can configure your NIC settings with onboard jumpers or NIC configuration software usually provided by the manufacturer. If you are using a Plug-and-Play operating system, your NIC setting can be configured automatically in most cases.

10.

Correct Answers = B and C

A peer-to-peer network is a small network, usually of 10 or fewer computer systems, connected without the use of a larger specialized server computer. In peer-to-peer networks, a workstation can function as both a client and a server computer.

11.

Correct Answer = D

Legacy NICs were configured with the use of jumpers or DIP switches on the card itself. Today, most NIC settings are configured with the use of software provided by the manufacturer or simply by letting Plug and Play make the necessary settings automatically.

12.

Correct Answer = B

If you are unable to install new software programs or device drivers on your system, your virus protection software or firewall may be blocking your install abilities. You may have to disable real-time protection or disable your entire antivirus suite altogether before installing new software.

13.

Correct Answer = D

NetBIOS is not routable. NetBIOS works well in LANs not WANs. For WAN communication you need TCP/P. NetBEUI is a non-routable small efficient transport-layer protocol meant for use in small networks with 1–200 workstations.

14.

Correct Answer = B

SDSL (Symmetric DSL) is well suited for business applications and programs that require and depend on the same speed for sending and receiving data. With SDSL, your upstream speed is the same as your downstream speed.

15.

Correct Answer = D

Unlike when you use less secure cable modem services, DSL is not a shared service connection. To be more specific, you do not share your DSL connection with your neighbors as cable subscribers do.

16.

Correct Answer = E

All of the statements are true of satellite Internet connectivity.
