B

Question 3

____ is the telltale factor for ascertaining where faults in a cable lie.
A) Resistance
B) Impedance
C) Voltage
D) Current

Accepted Answer

Impedance is the key factor in determining the location of faults in a cable because it takes into account both the resistance and reactance of the cable, providing a more comprehensive measure of its electrical characteristics.

Question 4

Most wireless testing tools contain more powerful antennas than a workstation NIC.

Accepted Answer

This is because wireless testing tools are designed specifically for testing and analyzing wireless networks, and therefore have more powerful antennas that allow them to capture and analyze signals that a standard NIC may not be able to detect.

Question 5

When used on a copper-based cable, a continuity tester applies a small amount of ____ to each conductor at one end of the cable.
A) resistance
B) impedance
C) voltage
D) current

Accepted Answer

A continuity tester applies a small amount of voltage to each conductor at one end of the cable. This allows the tester to determine if the circuit is complete or if there are any breaks or interruptions in the cable.

Question 6

A____ is a small electronic device that issues a signal on a wire pair.
A) tone locator
B) probe kit
C) tone generator
D) probe

Accepted Answer

A tone generator is a small electronic device that issues a signal on a wire pair. It sends a tone signal that can be detected by a tone locator or probe kit to locate wires in a wall or trace a cable.

Question 7

Some software errors point to a physical connectivity problem.

Accepted Answer

Some software errors can be caused by physical connectivity issues between hardware components or devices, such as a loose cable or faulty port. It is important to check for these types of issues before assuming the software is the sole cause of the problem.

Question 8

An administrator should take the time to troubleshoot all network problems correctly by asking specific questions designed to identify the problem ____.
A) intensity
B) background
C) scope
D) focus

Accepted Answer

The word "scope" refers to the extent or range of something. Therefore, when troubleshooting a network problem, it is important to identify the scope of the issue, such as whether it is affecting a single user or multiple users. By asking specific questions related to the scope of the problem, an administrator can narrow down the possible causes and solutions. The other answer choices, intensity, background, and focus, do not accurately describe the type of questions an administrator should ask when troubleshooting a network problem.

Question 9

____ packets exceed the medium's maximum packet size.
A) Jabber
B) Ghost
C) Giant
D) Runt

Accepted Answer

A giant packet is a packet that exceeds the maximum packet size allowed by the particular medium or technology. A jabber packet refers to a transmission that is uninterrupted for an unusually long time, and a ghost packet is not a commonly used networking term. A runt packet is a packet that is too small to be of any use or value.

Question 10

A ____ system is a process or program that provides support personnel with a centralized means of documenting changes to the network.
A) release management
B) asset management
C) change document
D) change management

Accepted Answer

A change management system is a process or program designed to provide support personnel with a centralized means of documenting changes to the network. It helps teams manage and track changes to network configurations, software and hardware, and ensures that changes are made with proper planning, testing and approval processes. Release management refers to the management of software releases or updates, while asset management involves tracking and managing an organization's hardware and software assets. Change document on the other hand refers to a record of the changes made during a specific period.

Question 11

____ are often considered third-level support.
A) Help desk coordinators
B) Help desk analysts
C) Administrators
D) Technical specialists

Accepted Answer

The answer of ____ are often considered third-level support.
A) Help...

Question 12

____ is a fundamental property of wire that depends on a wire's molecular structure and size.
A) Voltage
B) Current
C) Resistance
D) Impedance

Accepted Answer

Resistance is a fundamental property of wire that depends on its molecular structure and size. It is the measure of how strongly a wire opposes the flow of electric current through it. Voltage, current, and impedance are all related to resistance, but they do not directly depend on a wire's molecular structure and size.

Question 13

Continuity testers can only be used to test copper cable.

Accepted Answer

Continuity testers can be used to test the continuity of various types of electrical conductors and circuits, not just copper cables.

Question 14

A ____ is a document (preferably online) that lists every service and software package supported within an organization, plus the names of first- and second-level support contacts for those services or software packages.
A) call tracking list
B) help desk program list
C) supported services list
D) change management list

Accepted Answer

The description best matches a supported services list, which documents all services and software packages supported within an organization and provides first- and second-level support contacts for them. A call tracking list is a list that tracks incoming support requests, a help desk program list is a list of programs used by the help desk, and a change management list is a list of changes made to the organization's systems.

Question 15

To take advantage of network monitoring and analyzing tools, the network adapter installed in the machine running the software must support ____ mode.
A) open
B) static
C) promiscuous
D) continuous

Accepted Answer

Promiscuous mode allows the network adapter to capture all network traffic, including traffic not addressed to it, allowing for more comprehensive analysis and monitoring.

Question 16

____ are often considered first-level support.
A) Help desk coordinators
B) Help desk analysts
C) Administrators
D) Network specialists

Accepted Answer

Help desk analysts are typically the first point of contact for users seeking technical support, making them first-level support.

Question 17

Resistance is measured in ____.
A) ohms
B) hertz
C) centimeters
D) volts

Accepted Answer

Resistance is measured in ohms, which is a derived unit of the International System of Units (SI). Hertz is used to measure frequency, centimeters are used to measure length, and volts are used to measure electric potential difference.

Question 18

Logical connectivity problems often prove more difficult to isolate and resolve than physical connectivity problems.

Accepted Answer

Logical connectivity refers to the ability of devices to exchange information and communicate effectively. Logical connectivity problems may be caused by issues such as misconfigured network settings, software errors, or security restrictions. These problems can be more complex and challenging to diagnose than physical connectivity issues such as damaged cables or faulty network cards.

Question 19

Tone generators and tone locators are used to determine characteristics about a cable.

Accepted Answer

Tone generators and tone locators are primarily used to trace and identify specific cables within a group and do not determine characteristics about a cable such as its length or quality.

Question 20

A ____ can be used to intercept a telephone conversation.
A) sniffer
B) protocol analyzer
C) network monitor
D) butt set

Accepted Answer

A butt set is a telephone test set that can be used by technicians to monitor and intercept phone conversations. It allows them to listen in on conversations and test lines for faults. Sniffers, protocol analyzers, and network monitors are typically used for analyzing network traffic and data packets, and are not specifically designed for intercepting phone calls.
