Question 1

A technician replaces a computer's power supply after it was damaged by a power surge. What should they suggest to the customer to prevent future damage?

Correct Answer: Use an Uninterruptible Power Supply (UPS)

The best answer is to use an Uninterruptible Power Supply (UPS). A UPS provides battery backup power to the computer during power surges or outages, allowing for a safe shutdown and preventing damage to sensitive components like the power supply. Avoiding computer use during storms is not always practical and does not guarantee protection. Reducing power consumption would not prevent damage from power surges. Installing a more powerful power supply does not address the root issue of unexpected power fluctuations. Therefore, recommending a UPS is the most effective solution to protect against future power surge damage.

Question 2

A small office frequently experiences power surges during storms. Which of the following is the best recommendation for protecting their electronic devices?

Correct Answer: Install surge protectors on all devices

Installing surge protectors on all devices is the best recommendation for protecting electronic devices in an office that frequently experiences power surges during storms. Surge protectors are designed to absorb excess voltage and prevent it from damaging connected devices. Unplugging devices during storms can help, but is not always practical or reliable. Wrapping devices in aluminum foil does not provide effective surge protection. Switching off the circuit breaker would cut power to the entire office, which is disruptive and unnecessary when surge protectors can handle the issue at the device level.

Question 3

A laptop user is working in a public location and is concerned about potential power surges. What should they use for their laptop's power?

Correct Answer: A portable surge protector

A portable surge protector is the best choice for a laptop user working in a public location who is concerned about potential power surges. Surge protectors are designed to protect electronic devices from voltage spikes and power surges that can damage sensitive components. Using a portable surge protector allows the user to safely connect their laptop to a power outlet while providing an extra layer of protection against unexpected power fluctuations. An extension cord alone does not offer surge protection and may even increase the risk of damage if the cord is low quality or overloaded. Relying solely on battery power limits the user's working time and is not a practical long-term solution. Sharing power with another device is not recommended, as it can lead to power issues and potential damage to both devices.
