Abdel, an electrician, does not know much about computers so he orders a custom computer with a 1000 W power supply. However, the maximum wattage the system needs is 500 W.Which of the following statements are true? Select two.

The 1000 W power supply will last longer than, for example, a 750 W power supply. Correct. A 1000 W power supply operating at 500 W will last longer because the load is only 50% of its capacity so it is not stressed. It will also run cooler. The power supply will only deliver up to 500 W of power and operate very efficiently. Correct. The power supply will only deliver as much power as is being requested so it will only deliver 500 W of power in a very efficient manner.

Which two statements are true about 4-pin 12 V, 8-pin 12 V, 6-pin PCIe, and 8-pin PCIe connectors?

The 6-pin and 8-pin PCIe connectors provide auxiliary power to video cards. Correct. The 6-pin and 8-pin PCIe connectors provide auxiliary power to high-end video cards using PCI Express. The 4-pin 12 V and 8-pin 12 V connectors provide auxiliary power to the CPU. Correct. The 4-pin 12 V and 8-pin 12 V connectors are auxiliary system board connectors used to provide an extra 12 V of output to the processor.

Larry got a new job and moved from New York to Hawaii. After a couple of weeks, he notices that occasionally, the time, date, and time zone are all wrong. He has no idea what is happening and believes it is because he moved to a different time zone.What is likely to be causing the problem?

The CMOS battery is failing and needs to be replaced. Correct. Larry should replace the coin cell battery that sends a charge to the CMOS RAM. The battery provides a trickle charge to the CMOS RAM so that when the computer is turned off, the CMOS settings remain as they were.

A restricted computer lab at a college has been set up with local authentication. Students are able to log in but do not have internet access. You check the network settings on one of the computers and it has an IP address of 169.254.1.10. What is the problem?

The DHCP server is not reachable Correct. When a computer is configured to request an IP address from a DHCP server on power up, and the DHCP server is not available or reachable, the operating system will assign an address in the 169.254.x.y address space (APIPA, Automatic Private IP Addressing). This allows devices in the local network to have connectivity with each other but not with computers on another network, hence internet access is not possible. The host will transmit a DHCP discover message periodically in an attempt to obtain an address from a DHCP server.

You buy a PoE (Power over Ethernet) security camera in a liquidation sale that requires at least 22 Watts of power. Before installing it, you test it by connecting it to a switch capable of transmitting power based on the PoE IEEE 802.3af standard. However, the camera does not turn on. Which of the following best describes the problem?

The PoE device is not transmitting enough power to turn on the camera Correct. The IEEE 802.3af standard provides up to 15.4 watts of power but the camera requires at least 22. The solution would be to either use a camera that requires less power or upgrade the switch to one that supports PoE+ (802.3at) which can deliver up to 25.5 watts through CAT-5 cabling.

Torino receives a call from a SOHO client who says her computer is not working. He goes to her office and checks the network settings. He notices that the default gateway entry is blank, yet he can ping the router. Once he enters the default gateway, the problem is solved. What did the client mean when she said her computer is not working?

The computer had no internet access Correct. If the default gateway is not set, the computer will not be able to send traffic outside of the local network. He can ping the default gateway because the router interface is part of the local network. The address on the router interface is the default gateway but the computer does not know this unless it is explicitly configured either manually or automatically using DHCP.

After Sandy and a friend troubleshoot her laptop they determine the LCD screen needs to be replaced. Sandy gets tired of waiting on her friend, who knows more about computers, and decides to do it herself by watching videos online. In the process, she accidentally breaks one of the two cables that wrap around the screen and connect to the mini-PCIe card inside the laptop.What is the impact of this mishap?

The laptop will lose its Wi-Fi capabilities. Correct. The card, wires, and mini-PCIe card described are the wireless card and antennas. If Sandy were to cut the cables on the antennas, she would not be able to connect to the Wi-Fi.

What three characteristics are true about SRAM and DRAM?

The type of memory used in a memory cache is SRAM because it is faster Correct. The type of memory used in cache memory is SRAM; it is faster than DRAM. Both are considered volatile because they only hold data while power is on Correct. Once power is removed from SRAM and DRAM the information stored is lost. Correct! SRAM is faster than DRAM because it does not need to be refreshed Correct. SRAM does not need additional clock cycles to refresh the data. DRAM, or dynamic RAM, is the most common type of RAM and loses its data rapidly, so the memory controller must refresh it several thousand times a second.

Your customer wants to build a new computer and needs to make sure he orders the correct power supply for his machine.What should you tell him to check to make sure he orders the correct power supply? (Select all that apply.)

Wattage requirements Correct. Wattage requirements are the total amount of wattage or power needed based on the number of devices connected to the system. If the customer doesn't have enough wattage for his computer, the computer will not turn on. Additionally, if he has a power supply with too much wattage, he will have spent extra money unnecessarily. The power supply should be capable of delivering at least 30% more wattage (power) than the maximum power the system is capable of drawing. Form factor Correct. Because the customer must be able to mount the power supply to the case, form factor is an important consideration. If he purchases the wrong form factor, the power supply will not fit, and he will have to return the power supply and purchase the correct form factor. Correct! Number of hard drivesCorrect. The customer will need to make sure he has a SATA power connector for each hard drive, from the power supply. If he doesn't have enough SATA power connections, he will not be able to install all the hard drives that he plans to use in his computer. Correct! Video requirementsCorrect. If he is ordering a video card, he will need to make sure he has the power connector required for the video card. He will need either a 6-pin or an 8-pin video card power connector. There is also a possibility that he will need two 6-pin connectors. If he decides to install multiple video cards, he will need a sufficient number of 6-pin or 8-pin power connectors for each video card power connector.

A technician is building a custom gaming computer for a customer. In what order should the technician install the main components?

power supply, drives, motherboard, cards Correct. Since the motherboard and processor are the most expensive components, if possible it is best to install the motherboard just before installing the expansion cards to prevent damage. For example, you would not want to drop a disk drive or power supply on the motherboard while installing those components.

Lin is booting up his computer. Sometimes during the boot process, the computer will shut down, but more often than not it will reboot on its own or simply freeze. He thinks the problem could be due to an intermittent undervoltage problem with the power supply, so he uses a power supply tester. The test shows that the power supply is functioning properly.What should Lin check next in the troubleshooting process?

rAM Correct. RAM is the simplest thing Lin can check in this troubleshooting process. To reseat RAM, Lin pulls outward on the supporting arms that secures the memory module in the DIMM slot, removes the memory, and reseats it. He pushes down gently but firmly on both ends of the memory stick until the supporting arms latch it in place. Faulty RAM will typically not cause the computer to shutdown but troubleshooting this component can at least rule it out as being the problem.
