CHAOS Chapter 3 Part 3 (3.11 - 3.14)
Overheated processor.
A computer was brought into your help desk center for repair. You have been told that it randomly locks up. Which of the following is MOST likely causing this issue?
AMR
A dedicated bus type used by dedicated video cards.
HDMI Output
A technician wants to connect a computer to a high-definition television (HDTV). The technician has attached an HDMI cable from the video card to the television. However, the video card is only sending a video signal over the cable. The technician decides to use the audio pass-through technique to deliver audio to the television. An audio output cable is connected to the video card and television. Which of the following options was used for the audio pass-through?
AGP
Attaches to the motherboard to allow additional cards to be installed.
PCI Express (PCIe)
Data rates depend on the protocol version and number of transmission lines.
PCI Express (PCIe)
Each bus slot routes data through a point-to-point dedicated connection.
Power supply
Exhausts hot air out of the back of the case
Active heat sink
Has a fan attached to the heat sink
Passive heat sink
Has no fan attached to the heat sink
Peripheral Component Interconnect (PCI) PCI Express (PCIe) AGP AMR
Match each bus type on the back of the card to the appropriate characteristic on the next cards. (You can use a bus type more than once.)
Active heat sink Liquid Cooling Power supply Passive heat sink
Match the cooling system types on the left with the appropriate characteristics and uses on the back of the card. Each cooling system type can be used once, more than once, or not at all.
Peripheral Component Interconnect (PCI)
Replaced ISA and VESA bus standards.
Peripheral Component Interconnect (PCI)
The CPU and bus can process concurrently.
PCI Express (PCIe)
Typically used for network cards, USB cards, and sound cards.
Active heat sink
Used for cooling CPUs
Liquid cooling
Used for cooling high-end gaming computers
Active heat sink
Used for cooling high-end video cards
Liquid cooling
Used for cooling high-performance systems
Passive heat sink
Used for cooling memory modules
DAC
Which component is responsible for converting digital audio into sound that can be played on speakers?
WMA AIFF WAV
Which of the following are common digital audio file types? (Select three.)
Power supply.
Which of the following components converts AC power to DC power?
Play digital audio directly from an internal CD player, and compress audio data to support Dolby Digital or DTS surround sound.
Which of the following features are supported by digital audio in a sound card? (Select two.)
Throttling
Which of the following processor features is MOST likely to significantly reduce power consumption based on current operating conditions?
The 8-pin EPS12V connector provides four lines of 12 V power to the CPU.
You are building a high-performance gaming PC with a modern multi-core processor. Which of the following statements about the 8-pin EPS12V connector is correct?
Replace the power supply because it is failing.
You are servicing a client's computer that has been randomly restarting. You decide to test the power supply voltage on the 12 V rail using a multimeter. Which of the following BEST describes the action you should take based on the multimeter reading shown below?
Removing the case side panel.
You have a system that has been overheating. Which of the following actions will NOT help to keep the system cool?
Primary (first) video card
You have installed two multi-GPU CrossFire video cards in your computer and linked them together using a bridge clip. You now need to connect your monitor to test the video card installation. Where should you connect your monitor on your computer?
Check the CPU fan power. Make sure the heat sink is properly mounted and has thermal paste.
You have just finished upgrading the CPU in your desktop system. After running the system for about 10 minutes, the system locks up and automatically restarts. Which of the following is the BEST first steps in troubleshooting the problem? (Select two.)
D.
You have just installed a new hard drive in your desktop computer. Which of the following power supply connectors is designed to provide power to your new hard drive? (Select the correct connector.)
Download and install the latest driver from the video card manufacturer's website.
You have just installed a new video card in a employee's Windows workstation. When you power the system on and load the OS, everything on the screen looks enlarged and pixelated. You try to change the resolution, but the only available option is 640x480. Which of the following BEST resolves this problem?
Recording
You recently purchased a USB audio headset and connected it to a USB port on your Windows system. The headset includes a microphone that can be used to record audio. However, when you launch your audio recording program, no audio is recorded. You need to reconfigure the system to use the headset mic instead of the built-in mic. Click the tab you would use in the Sound Properties window to accomplish this task.
Inspect the power supply unit for a manual voltage switch and move it to 230 VAC. Otherwise, no action is necessary.
Your company relocated you from the United States to their United Kingdom office in London. You brought your personal computer with you, and you are in the process of setting it up. Your computer was previously configured to receive 115 VAC, but the electricity in London uses 230 VAC. Which of the following would allow your computer to run on 230 VAC?
