Each of these computes uses a wireless mouse and keyboard. Therefore, your company goes through a lot of alkaline batteries. When these batteries can no longer power the intended device, you need to decide what to do with them. Unless otherwise dictated by your local authorities, which of the following would be the EASIEST way to deal with these batteries? They can be thrown in the trash. They can be recharged. They must be stored onsite until they expire. They must be sent to hazardous waste collection. Explanation

There is no need to send them to a hazardous waste collection. Alkaline batteries do not have an expiration date that needs to be meet before they can be thrown away. Technically speaking, an alkaline battery can be recharged, although most manufactures tell you not to recharge them. If you recharge an alkaline battery, you risk an explosion, and you will have a low-quality battery if the charge is successful. Storing the batteries onsite until they expire does not address the issue of proper disposal.

As a result, you often have old laptop batteries. Unless otherwise dictated by your local authorities, which of the following is the BEST way to deal with these types of batteries? They can be recharged. They must be recycled. They can be thrown in the trash. They must be stored on-site until they expire.

Therefore, these batteries must be recycled or given to a hazardous waste facility. Because the toxic substances in laptop batteries can harm the environment (such as entering the food chain, adversely a ff ecting plants, animals, and humans), they should never be thrown in the trash. Since new computers come with their own new battery, there is no need to recharge and keep the old batteries. In addition, these batteries lose their holding capacity and will most likely not be able to power a device for any useable length of time. Laptop batteries do not need to be keep on-site until a certain expiration date has been meet. Once you are done with them, they can be recycled or deposited at the hazardous waste facility.

Video card Notebook battery Hard disk drive Motherboard Explanation Ni-Cad, NiMH, and other notebook battery types can contain regulated materials. Read the battery's documentation for a description of correct disposal procedures. Incorrect disposal can result in serious fi nes. While using special recycling services when disposing of computer components is environmentally friendly, most locations do not have laws regarding the disposal of most common components such as motherboards, video cards, and hard disk drives.

While swapping motherboards in a server in the data center, she notices that the original motherboard is showing signs of corrosion. Which of the following is the BEST solution to resolve the corrosion issue? Decrease the humidity in the data center. Replace motherboards in the servers more frequently. Check and clean all corroded server motherboards. Run a diagnostic check on all servers to make sure they are functioning properly. Explanation Corrosion of server components is a sign of high humidity in the environment. And San Francisco is one of the highest humidity cities in the United States. The recommended humidity level is usually between 50 and 65%. The best solution in this scenario is to decrease the amount of humidity in the data center to an acceptable level. Replacing motherboards is costly and is not the best solution in this scenario, given that the new motherboards will probably also corrode. Cleaning the server components will not solve the issue of continuing corrosion. While Katy could run diagnostics to check for server performance, this approach would not solve the issue of continuing corrosion of server components.

Place them in the regular trash. Return them to the manufacturer for recycling. Deliver them to a local recycling facility. Place them in a standard recycling bin. Explanation Empty printer cartridges should be returned to the manufacturer for recycling. Most manufacturers accept the empty cartridges back from you, re fi ll them, and then resell them. This reduces land fi ll waste, provides the manufacturer with a cheap source of empty cartridges, and provides you with a source for less expensive printer cartridges. While local recycling facility will only recycle the cartridge plastic. The best solution is to have the cartridge re fi lled for reuse. Placing a printer cartridge in the regular trash simply results in the cartridge being added to a land fi ll. You should recycle the cartridge. Placing the printer cartridge in a standard recycling bin can result in the cartridge being sorted out for being thrown into a land fi ll. The best solution is to have the cartridge re fi lled for reuse.

Internal cooling systems Maintaining a steady temperature Hot and cold aisles Internal fans Explanation Server rooms and data centers often use hot and cold aisles that are designed to ensure that hot air is removed and cool air is pushed into the room. Internal fans, cooling systems, and a well-maintained temperature are important, but do not assist with the ventilation concerns in a server room.

To perform accurate testing, a large number of computers are required, sometimes numbering in the hundreds. Recently, you have noticed that the lights in the testing lab seem dimmer than normal and sometimes ﬂ icker. Which of the following electrical terms BEST describes the condition you are most likely experiencing? Power spike Power surge Brownout Blackout Explanation The dimming or ﬂ ickering is most likely caused by a drop in the voltage to the lab due to the large number of computer being run at the same time. This drop in voltage is known as a brownout and can be harmful to your computers. You should take steps to maintain a constant level of electricity. Power surges (also called power spikes) are abnormally high voltages that last for short periods of time. These can also be harmful to your computers. A blackout is a total loss of power. A power spike is like a power surge, but it lasts for milliseconds instead of seconds. References  2.2.3 Power Concerns  2.2.5 Power Concern Facts q_pwr_prot_brownout_pp7.question.fex

Secondary LCD monitor Laser printer Inkjet printer External hard disk drive Explanation Due to the periodic high power requirements to heat the fuser roller, a laser printer should not be plugged into a UPS's battery backup outlets. Instead, a laser printer should only be plugged into the surge protection outlets or directly into a wall outlet. Inkjet printers, external hard drives, and secondary LED monitors can be plugged into battery backup outlets.

(Select two.) Protects network cabling from EMI Conditions the power signal Prevents ESD Prevents electric shock Protects from over-voltages Explanation A typical UPS protects a computer from overvoltages as well as undervoltages. Also, because the quality of the electrical signal provided by a UPS battery is not as good as the AC power from the wall outlet, UPS devices often have built-in line conditioners. A UPS unit does not prevent electric shock, prevent ESD, or protect cabling from EMI.

As such, your company has been experiencing several brownouts due to power grid problems (too much demand and not enough electricity). Fearing that your computers (especially the servers) could be damaged by these brownouts, your manager has asked you to fi nd a solution to this problem. Which of the following would be the BEST device to recommend to your manager for computer protection? UPS Power strips GFCI Surge suppressor Explanation An uninterruptible power supply (UPS) is a device that contains a large battery suitable to run the attached devices for an extended period of time in the event that power is lost or drops below an acceptable level. A UPS can protect your computers from brownouts, power surges, and blackouts. UPSs can be purchased in varying size to accommodate large server or individual computers. A surge suppressor is typically a small box with several utility outlets, a power switch, and a three-wire cord for plugging into a wall outlet. The purpose of this device is to protect the electrical devices plugged in the suppressor from voltage spikes or power surges. A surge suppressor will not protect equipment from a drop in voltage. A power strip can sometimes include a surge suppressor, but often only provides a way to plug multiple appliances into on wall outlet. A ground-fault circuit interrupter (GFCI) is a protection device designed to protect people from electric shock from an electrical system. A GFCI protects you from ground faults (such as an electrical short). You often see these outlets in bathrooms and kitchens, where the chance of an electrical shock is greater due to water.
