Correct answer: The motherboard should support either SLI or CrossFire. Correct answer: For the best performance, both video cards should be identical. Explanation For increased performance, especially in games, you can link multiple video cards together using a special bridge clip. This allows multiple GPUs to draw a single screen. For the best performance, both video cards should be identical. In addition, the motherboard must be compatible with either SLI (used by NVIDA cards) or CrossFire (used by AMD cards). You cannot link an SLI video card with a CrossFire video card. Because each card is sharing the processing load, the memory banks and GPU in both video cards are being used. In a multi-GPU configuration, the secondary (bottom) card's display connectors are typically disabled.
A customer wants to add an additional video card to her computer so she can play the latest computer games. As a result, this system will now have a multi-GPU configuration. Which of the following statements are true when it comes to a multi-GPU configuration? (Select two.) Answer Linking video cards also provides additional video output ports. The motherboard should support either SLI or CrossFire. Linking only shares memory resources, not GPU resources. An SLI video card can be linked with a CrossFire video card. For the best performance, both video cards should be identical.
Correct answer: HDMI output Explanation With audio pass-through, an audio output cable is connected to the video card. The video card combines the audio signal with the video signal for HDMI output. This option is sometimes called HDMI out. Multi-GPU links video cards together to share the graphic processing load between the two GPUs. DirectX is a collection of application program interfaces (APIs) that improves graphic, animation, and multimedia creations. OpenGL is an alternative standard to DirectX that is used by some applications. Most video cards support both DirectX and OpenGL. HDCP is a method for protecting digital media.
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? Answer Multi-GPU HDMI output HDCP DirectX/OpenGL
The CPU and bus can process concurrently. Peripheral Component Interconnect (PCI) Replaced ISA and VESA bus standards. Peripheral Component Interconnect (PCI) Each bus slot routes data through a point-to-point dedicated connection. PCI Express (PCIe) Typically used for network cards, USB cards, and sound cards. PCI Express (PCIe) A dedicated bus type used by dedicated video cards. AGP Attaches to the motherboard to allow additional cards to be installed. AMR Data rates depend on the protocol version and number of transmission lines. PCI Express (PCIe)
Drag each bus type on the left to the appropriate characteristic on the right. (You can use a bus type more than once.) The CPU and bus can process concurrently. Replaced ISA and VESA bus standards.\ Each bus slot routes data through a point-to-point dedicated connection. Typically used for network cards, USB cards, and sound cards. A dedicated bus type used by dedicated video cards. Attaches to the motherboard to allow additional cards to be installed. Data rates depend on the protocol version and number of transmission lines.
Correct answer: Riser Explanation Riser cards attach to the motherboard and allow additional cards (called daughter cards) to be installed. The primary benefit of a riser card is that by installing expansion cards parallel to the motherboard, it's possible to create a low-profile design. Communications networking riser (CNR) is a type of expansion slot found on some motherboards that is used for network and sound expansion boards. Personal Computer Memory Card International Association (PCMIA) cards were used several years ago to add devices to laptops. VESA local bus was also a type of expansion slot found on older motherboards that was primarily used for the video interface.
For a special project, you have been asked to recommend the lowest profile desktop computers available. You are attempting to put together the specifications for these machines. Which of the following types of cards are attached to the motherboard and allow additional cards to be installed? Answer PCMCIA Riser Communications and networking riser VESA local bus
Correct Answer: Purchase two graphics cards with SLI and similar specifications. Correct Answer: Purchase a motherboard with two (or more) PCIe x16 slots. Correct Answer: Connect at least one monitor to the graphics card. Explanation For increased performance, especially in games, you can install multiple video cards and link those cards together so that multiple GPUs draw a single screen. Scalable Link Interface (SLI) from NVIDIA and CrossFire from AMD are two different methods for linking video cards. In most cases, you will need to install identical video cards, or at least video cards with very similar specifications. Cards are linked using a special bridge clip or through software (depending on the implementation). Both the motherboard and the video cards must support the selected method (either SLI or CrossFire). The motherboard must have at least two 16x PCIe slots. Some motherboards are able to link an onboard graphic controller and video card installed in a single PCIe slot. Connect the monitor to an output port on the first video card. VGA is an older video technology and would not be used for SLI. Graphics card power requirements, even for SLI, would not require dual 1200-watt power supplies. Hard drive speed is independent of SLI.
You are in the process of building a new computer. You would like to configure your computer to use SLI to improve performance while playing your favorite game. Which of the following will MOST likely be part of the configuration process? (Select three.) Answer Purchase a motherboard with integrated video and an AGP 8x slot. Purchase a 7200 rpm or better hard drive. Purchase two graphics cards with SLI and similar specifications. Purchase a motherboard with two (or more) PCIe x16 slots. Purchase a motherboard with integrated video and an add-on card that supports the VGA standards. Connect at least one monitor to the graphics card. Purchase dual 1200-watt power supplies.
Correct answer: Buy your friend's games, monitor, and video card. Swap out both your video card and monitor. Explanation The LCD TN monitor with the 144-Hz refresh rate along with the video card with a max refresh rate of 144 Hz will give you the best gaming experience compared to the other options. Remember that in order to achieve a specific refresh rate, the following components must all support the same maximum refresh rate: Display device Video card Display cable Fast-moving graphic applications, such as games, perform best with a refresh rate of 120 Hz or higher, which is covered by this option. Also, LCD TN panel monitors have a much faster response time, which makes them superior for gaming when compared to LCD IPS panel monitors. The newer video card with a max refresh rate of 240 Hz has some advantages over the older card, but not in combination with the LCD IPS panel monitor. Either option where you keep the 60-Hz monitor, the 75-Hz card, or both will limit system performance to the rate of the slowest component, which will not be sufficient for the fast-moving graphics in the games.
You have a friend who is offering to sell the monitor and video card from his gaming system along with several PC games. The games have fast-moving graphics, and you want to be able to play them on your own home system. The monitor he is selling is an LCD TN with a 144-Hz refresh rate. The video card he is selling supports a max refresh rate of 144 Hz. You're sure you want to buy the games, but you have a couple of other choices when it comes to the monitor and the video card. The monitor in your current system has a 60-Hz refresh rate. The video card has a max refresh rate of 75 Hz. This configuration has always worked fine for watching videos. You're also looking at new 60-Hz LCD IPS monitors and several high-end video cards with max refresh rates of up to 240 Hz. Which of the following will MOST likely allow you to play the games on your home system with the best gaming experience possible? Answer Buy your friend's games, monitor, and video card. Swap out both your video card and monitor. Buy the games and use your existing card and monitor. Buy the games from your friend and spend some extra money on the newer 60-Hz LCD IPS monitor and one of the newer 240-FPS video cards. Swap out both your video card and monitor. Buy the games and the monitor from your friend. Swap out just your current monitor, and use your existing video card.
Correct answer: Primary (first) video card Explanation After installing your two multi-GPU CrossFire video cards, you should connect your monitor to the primary (first) video card. Connecting to the second video card will cause issues. In order to take advantage of your new video card's features, you need to connect the monitor to the primary video card, not the onboard video adapter.
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? Answer Both the primary and secondary video cards Primary (first) video card Onboard video adapter Secondary (second) video card
Correct answer: Download and install the latest driver from the video card manufacturer's website. Explanation You should download and install the latest video driver from the manufacturer's website. Because Windows didn't have the appropriate driver, it used a generic driver instead, which supports a very limited resolution. Windows Safe Mode is used to troubleshoot system issues and disables all unnecessary software and drivers. If BIOS compatibility were an issue, nothing would be displayed on the monitor. A monitor's refresh rate does not affect a system's max resolution.
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? Answer Reboot the system into Safe Mode. Download and install the latest driver from the video card manufacturer's website. Upgrade the monitor to one that supports a higher refresh rate. Verify that the system BIOS is compatible with the video card.
Correct answer: You have not configured the motherboard in BIOS/UEFI to utilize the new video card. Explanation Before installing the video board in the slot, you need to go into the motherboard's BIOS or UEFI firmware utility to configure the motherboard to use the new video board of the integrated video adapter. As long as you are installing a single video card into a compatible PCIe slot, using a wrong PCIe slot should not be an issue. While disabling the integrated video adapter in BIOS/UEFI is not recommended (in case you have to remove the video card), it should not impact the display, as the monitor is connected to the video card. Bridge clips are used to link more than one video card together. They are not used (and it is not necessary) to link the integrated video adapter to a video card.
You have just installed a video card in a PCIe expansion slot in your Windows workstation. You have made sure that the card is connected to the power supply using an 8-pin connector. You also have your monitor connected to the video card. However, when you boot your workstation, it displays a blank screen instead of the Windows system. Which of the following is the MOST likely cause of the problem? Answer You have disabled the integrated video adapter. You inserted the video card into the wrong PCIe slot. You have not configured the motherboard in BIOS/UEFI to utilize the new video card. You forgot to link the bridge clip from the integrated video adapter to the video card.
Correct answer: Use an adapter to connect the monitor HDMI port to the DVI-D connector on the PC. Explanation Using an adapter to connect the DVI-D connector on the video adapter to the HDMI port provides the best quality output at the lowest cost. Because DVI-D and HDMI both use digital signaling, the signal is not degraded during conversion. In fact, HDMI was specifically designed to support DVI-D signaling. DVI-D to HDMI converters can be purchased for less than $20.00 USD. Using a DVI-D-to-VGA adapter would allow you to connect the video board to the monitor. However, this type of adapter must convert digital signals to analog signals, which would likely degrade the signal slightly. Purchasing a new monitor with a DVI-D port would provide a high-quality signal, but would cost much more than the other alternatives.
You need to connect a monitor that provides an HDMI port and a VGA port to a video adapter in a PC system that uses a DVI-D connector. Which of the following options provides the BEST display quality at the lowest cost? Answer Purchase a new monitor with a DVI-D port. Use an adapter to connect the monitor VGA port to the DVI-D connector on the PC. Use an adapter to connect the monitor HDMI port to the DVI-D connector on the PC. It is not possible to connect this monitor to this PC.
