Question 6 of 22
6. Question
2 pointsA technician is unpacking a new PCIe video adapter from an antistatic bag to install the card in a desktop computer. Which two measures should the technician use to protect the card and other computer components? (Choose two.)Correct
Incorrect
Using a grounded mat on the workbench and a correctly connected antistatic wrist strap while installing the card will protect it and other computer components from ESD damage. A low humidity work environment would increase the risk of ESD. The computer should be disconnected from all power sources while the technician is working on it. EMI can interfere with data signals when the computer is operating, but will not damage hardware components.Hint

8. Question
1 pointsWhat makes CRT monitor disposal dangerous for a technician who is handling the disposal?Correct
Incorrect
CRT monitors do contain lead, barium, and rare earth metals that can be dangerous to the environment if not disposed of properly, but the danger to the technician is in the high voltage levels that can be stored even after powering off the monitor and disconnecting the power cord. A technician might be disposing of a CRT monitor that has the cover ajar or removed and be exposed to the high voltage.Hint

9. Question
1 pointsA technician is troubleshooting connectivity issues to a PC and needs to verify which cable is plugged into the correct port of the patch panel. What tool should the technician use?Correct
Incorrect
A multimeter is used to measure electrical current. A punch down tool is used to punch down cables on a patch panel. A crimper is used to crimp cables in a connector, while a toner probe is used to identify connections to a patch panel. A tone generator is attached at one end and the toner probe is used to determine which cable at the other end (such as at the patch panel) is the appropriate cable.Hint

Question 21 of 22
21. Question
1 pointsA technician suspects that a power supply is faulty. How can it be checked?Correct
Incorrect
The temperature of the power supply does not indicate if it is operational. A PC technician should never open a power supply as dangerous voltages might still be present even when disconnected.
