External commands, on the other hand, are separate executable files located in the system's path.

Question 5

Of the following, which would be considered system utilities?

Accepted Answer

The answer of Of the following, which would be considered...

Question 6

Toolkits generally have _____ for the removal and replacement of jumpers.

Accepted Answer

Eyebrow tweezers are commonly used for the removal and replacement of jumpers due to their precision and ability to grip small components.

Question 7

Which of the following can prevent the discharge of ESD? (Choose all that apply.)

Accepted Answer

The answer of Which of the following can prevent the...

Question 8

CompTIA has created a six-step process for troubleshooting. The first step in the process is to identify the problem. Which of the followings steps resembles the next step in the methodology?

Accepted Answer

After identifying the problem, the next step in the CompTIA troubleshooting methodology is to establish a theory of probable cause.

Question 9

A technician has booted up the 5-year-old computer of a user who complains that the system suddenly no longer uses of his add-on audio card. Upon booting, the technician notices that the system time is 10 years in the past. Which one of the following is a probable cause to investigate?

Accepted Answer

The CMOS battery is responsible for maintaining the system time and BIOS settings when the computer is powered off. If the battery fails, the system time can reset to a default date, often many years in the past.

Question 10

What is the part of the computer system that receives inputs, directs those inputs to the processor, and redirects the processed data to outputs called at?

Accepted Answer

The answer of What is the part of the computer...

Question 11

Which of the following is likely to have a firmware component? (Choose all that apply.)

Accepted Answer

Firmware is a type of software that is embedded in hardware devices. It provides the basic instructions that the device needs to operate. All of the listed devices are likely to have a firmware component.

Question 12

Match the following procedures to the tools needed:
-Verify correct voltage from power supply.

Accepted Answer

A multimeter is an electronic measuring instrument that combines several measurement functions in one unit. It can measure voltage, current, and resistance. When checking a power supply, you would use the voltage measurement function of the multimeter to ensure the output is as expected.

Question 13

Match the following procedures to the tools needed:
-Clean the power supply and case fans.

Accepted Answer

Compressed air is commonly used to blow dust and debris out of computer cases, power supplies, and fans without introducing moisture or causing damage to the components. It is an effective way to clean these parts without having to touch them physically, which can help prevent electrostatic discharge (ESD) and other potential issues.

Question 14

Match the following procedures to the tools needed:
-Test I/O ports.

Accepted Answer

A loopback test involves using a loopback adapter or plug, which is designed to reroute the signals from the output back into the input of a port. This is a common way to test serial, USB, and network ports to ensure they are functioning correctly by sending and receiving signals.

Question 15

Match the following procedures to the tools needed:
-Research a BSOD (STOP) error.

Accepted Answer

When you encounter a BSOD error, it typically means that your computer has encountered a critical error that it cannot recover from, causing it to crash. To research the error code and find potential solutions, you would use online resources such as a Knowledge Base website. These websites often contain detailed information about various error codes and troubleshooting steps to resolve them. Examples of Knowledge Base websites include Microsoft's support site, tech forums, and other informational websites that specialize in computer troubleshooting and technical support.

Question 16

Match the following procedures to the tools needed:
-Test the network cable.

Accepted Answer

A cable tester is specifically designed to check the electrical connections in a cable or other wired assembly. It can test for continuity, resistance, and the correct allocation of wires, ensuring that the cable is functioning correctly. 
So the full answer to the input question is:
Test the network cable with an E. Cable tester.

Question 17

Match the following network installation functions with the correct tool:
-Checks cable continuity and wire-pair configuration.

Accepted Answer

A cable tester is the correct tool for checking cable continuity and wire-pair configuration. It is used to ensure that the electrical connections within a cable are correct and that there are no breaks or faults in the wiring. Cable testers can test for various types of cables, such as twisted pair, coaxial, and fiber optic, and can verify that the wires are properly connected and in the correct order.

Question 18

Match the following network installation functions with the correct tool:
-Use to set a UTP cable into a wall jack (keystone jack).

Accepted Answer

A punch down tool is used to insert and secure the individual wire leads into the corresponding slots in the keystone jack, ensuring a solid and reliable connection.

Question 19

Match the following network installation functions with the correct tool:
-Use this to test the transmit/receive functions of a network card.

Accepted Answer

C. Loopback plug
A loopback plug is a device used to test the ports on a network card to ensure they are working correctly. It essentially sends a signal out through the transmit channel and checks to see if the same signal is received back through the receive channel, thus confirming the card's ability to transmit and receive data.

Question 20

Match the following network installation functions with the correct tool:
-Within a batch of cables, use this to locate or match up a cable from one end of a long run with the other end of the cable.

Accepted Answer

A toner probe, also known as a tone generator and probe or a fox and hound, is used to trace wires and locate cables in a batch. The tone generator sends a signal down the cable, and the probe is used at the other end to detect the signal, thus identifying the correct cable among many.
