Question 2

A technician is troubleshooting a server that repeatedly trips the circuit breaker in the data center. The server is plugged into a power strip that is also serving two other high-power devices. What is the most appropriate safety and troubleshooting step?

Accepted Answer

Move one of the other high-power devices to a different circuit and plug the server directly into a wall outlet on its own circuit.. The repeated tripping indicates the circuit is overloaded. The safest and most effective step is to redistribute the load by moving one high-power device to a different circuit and plugging the server directly into a dedicated wall outlet. This isolates the server's power draw and prevents overloading the shared circuit, addressing the root cause without bypassing safety limits.

Answer

Replace the power strip with a higher-rated one and reset the breaker.

Answer

Reset the breaker and use a UPS with a higher wattage rating.

Answer

Install a larger circuit breaker in the panel to handle the load.

Question 3

During a printer toner replacement, a technician accidentally spills toner powder on the carpet. What is the correct procedure for cleaning up the spill?

Accepted Answer

Use a toner-rated vacuum or a damp cloth to carefully collect the spill.. Option C is correct because toner powder is a fine, electrically charged plastic dust that can be hazardous if inhaled or if it melts into carpet fibers. Using a toner-rated vacuum with a HEPA filter safely captures the particles without dispersing them, or a damp cloth can be used to gently lift the toner without smearing it deeper into the carpet. This procedure follows manufacturer safety guidelines and prevents damage to standard vacuums, which can ignite or spread the toner.

Answer

Use a standard household vacuum cleaner to quickly remove the toner.

Answer

Wipe up the toner with a dry paper towel and dispose of it in the trash.

Answer

Pour water on the spill to dissolve the toner, then mop it up.

Question 4

A technician is tasked with installing a new hard drive in a server rack. The rack is located in a cramped, dusty storage room with poor lighting. Which safety practice should the technician prioritize before beginning the installation?

Accepted Answer

Wear a dust mask and use a flashlight to improve visibility.. The correct answer is B because the scenario describes a cramped, dusty storage room with poor lighting, which creates two immediate hazards: inhalation of dust particles and reduced visibility. Wearing a dust mask protects the technician's respiratory system from airborne particulates, while using a flashlight ensures they can see clearly to avoid accidental contact with components or cables. These measures directly address the environmental risks before any work begins.

Answer

Use a step stool to reach the server rack safely.

Answer

Remove the server from the rack and place it on the floor for easier access.

Answer

Disconnect all power cables in the rack to eliminate electrical hazards.

Question 5

A technician is installing a new power supply in a desktop computer. After unplugging the system, what should the technician do before touching any internal components?

Accepted Answer

Press and hold the power button for 10 seconds to drain residual charge, then wear an ESD strap.. Option B is correct because pressing and holding the power button for 10 seconds after unplugging the system discharges the remaining charge in the power supply capacitors and other components, reducing the risk of electric shock or damage. Wearing an ESD strap then provides a path to ground for static electricity, protecting sensitive internal components from electrostatic discharge.

Answer

Wear a grounding strap and immediately open the case.

Answer

Spray the interior with compressed air to remove dust before touching anything.

Answer

Remove the CMOS battery first to ensure no power remains.

Question 6

A technician is replacing a damaged power supply in a desktop PC. After removing the old unit, the technician notices a large capacitor on the motherboard is bulging. What should the technician do to safely handle this situation?

Accepted Answer

Wear insulated gloves and carefully remove the motherboard for replacement.. A bulging capacitor indicates a failed or failing component that can leak electrolyte, cause further damage, or even burst. The safest course is to wear insulated gloves to avoid electric shock or chemical exposure and replace the entire motherboard, as the capacitor cannot be safely repaired in the field. Ignoring it or attempting makeshift fixes risks short circuits, fire, or injury.

Answer

Proceed with installing the new power supply and ignore the bulging capacitor.

Answer

Use a screwdriver to short the capacitor leads to discharge it.

Answer

Apply electrical tape over the bulging capacitor to contain it.

Question 7

A technician is setting up a new workstation in a cubicle. The cubicle has multiple power strips daisy-chained together to provide enough outlets. What is the correct safety action the technician should take?

Accepted Answer

Remove the daisy chain and plug each device directly into a wall outlet using a single power strip with surge protection.. Daisy-chaining power strips is a fire hazard because it can exceed the ampacity of the circuit, leading to overheating and potential electrical fires. The correct safety action is to remove the daisy chain and plug each device directly into a wall outlet, using a single power strip with surge protection to safely distribute power without overloading the circuit.

Answer

Continue using the daisy-chained setup since it is convenient and all strips are rated for 15 amps.

Answer

Replace all power strips with heavy-duty extension cords rated for the total load.

Answer

Install a UPS at the end of the daisy chain to regulate power.

Question 8

A customer reports that their computer shuts down unexpectedly after a few minutes of use. The system feels hot to the touch, and the fan is running loudly. What is the most appropriate first step for a technician to take to ensure safety while diagnosing the issue?

Accepted Answer

Unplug the computer, let it cool for 30 minutes, then inspect for dust or fan failure.. This question tests knowledge of electrical safety and proper handling of overheated equipment. The correct answer is to unplug the computer to prevent electrical shock or fire, then allow it to cool before inspecting internal components. Attempting to open a hot system or ignoring the heat can lead to injury or further damage.

Answer

Immediately open the case and touch the CPU heatsink to check temperature.

Answer

Spray compressed air into the vents while the system is running to clear dust.

Answer

Replace the power supply unit immediately to fix the overheating.

Question 9

A technician is called to a warehouse where a forklift accidentally struck a rack containing several desktop PCs. The rack is leaning, and one PC has fallen and is sparking. What is the technician's first priority for safety?
