CompTIA A+ - Hardware Part 2

Which of the following functions are performed by the Trusted Platform Module (TPM)?

A Trusted Platform Module (TPM) is a hardware cryptoprocessor that resides on the motherboard that stores and generates cryptographic keys. Using these keys, the TPM can generate a hash value based on the components installed in the system. The hash value can be used to verify that system components have not been modified when the system boots. Because each system will have a unique hash value, the hash can also be used as a form of system identification. Keys generated by the TPM can be used for encryption and authentication, but the TPM does not perform the actual encryption. The TPM is not designed to perform bulk encryption, directly encrypt data on the hard disk drive, or generate authentication credentials.

Which of the following actions occur during the Pre-EFI Initialization (PEI) stage of the UEFI boot process? (Select two.)

During the PEI stage of the UEFI boot process, the CPU and chipset are verified and fully initialized, and system memory is initialized, verified, and allocated. Device drivers are loaded into memory and the EFI boot manager initializes during the DXE (Driver Execution Environment) stage, which comes after the PEI stage. Power is supplied to the CPU during the Security (SEC) stage, which comes before the PEI stage.

Match each operating system attribute on the left with the correct description on the right.

Multiprocessing is the ability to use multiple processing devices. Multitasking is the ability to run multiple applications simultaneously. Multithreading is the ability to run multiple parts of an application simultaneously.

Which option is the first process that runs once a computer is powered on and the CPU loads the BIOS?

On a system using BIOS, the computer powers on, and then the CPU loads the BIOS. The first process to run is the Power-On Self Test (POST). Boot loader, Winload.exe, and WININIT load after POST.

What is the correct order for installing a processor for proper cooling?

The following is the correct order for applying devices to cool a processor: CPU Thermal paste Heat sink Fan

Which of the following BEST describes the print server?

A print server is the process that manages the flow of print requests for how and when documents are sent to the printer. The print queue is the location on the hard disk that holds print jobs that are waiting to be processed. The print driver is the software that allows the printer to communicate with the print device. The print spooling service captures print jobs from an application, holds them in a queue, and then sends each job to the print device.

Which of the following sound card port types can normally handle video content?

A sound card with an HDMI port can send high-definition audio to an HDMI device. Some sound cards can output video, or they can combine a video signal from a video card and output the combined audio/video. Some sound cards include one or more IEEE 1394 (FireWire) ports. These ports function as normal IEEE 1394 ports, which can be used to connect devices such as video cameras and can input both video and audio. TOSLINK, RCA, and Mini TRS ports on a sound card are only designed to output (or input) sound.

Match each of the motherboard components on the left with the appropriate description on the right. Each component is used once.

A typical motherboard includes the following components: Expansion slots, which allow you to expand the capabilities and features of a computer by installing expansion cards. Firmware, which is integrated software that is embedded in flash memory on the motherboard. Motherboards use either BIOS or UEFI firmware implementations. Because firmware is read-only, custom configuration settings are stored in non-volatile BIOS memory. CMOS battery, which is used to maintain an accurate time and date, even when the motherboard has no power. Older systems used the CMOS battery to power the CMOS chip, which contained custom BIOS settings. The chipset, which is a group of chips that facilitates communication between the processor, memory, and peripheral devices. Older chipsets consist of two integrated circuits: The north bridge, which controls communication between the CPU, memory, and high-speed graphics bus. The south bridge, which houses the PCI bus controllers and communicates with the super I/O controller.

Match the cooling system types on the left with the appropriate characteristics and uses on the right. Each cooling system type can be used once, more than once, or not at all.

Active heat sinks have an attached fan that helps cool off the component at a faster rate. Active heat sinks are used with the following components: CPUs High-end video cards Passive heat sinks do not have a fan and instead rely on increased surface area and passive air movement to cool the component. Passive heat sinks are used with the following components: Low-end video cards Memory modules ATX power supplies aid in cooling by exhausting hot air out the back of the case. Liquid cooling systems are used when air cooling is not sufficient. Because liquid cooling can dissipate heat much faster than air cooling, it is primarily used for high-end gaming computers and high-performance systems. Case fans create a pressurized system that allows air to flow through the case in a specific way.

Which of the following technologies enables you to scan a stack of documents automatically?

An automatic document feeder (ADF) is a scanner accessory that can scan a stack of documents automatically. Optical Character Recognition (OCR) is software that converts hard copy documents into digital information that can then be edited or transformed. OCR does not enable scanning a stack of documents automatically. Scan-to-folder is a network document scanning method that scans and transmits a digitized document directly to a network folder. Scan-to-folder does not enable scanning a stack of documents automatically. SSL (Secure Sockets Layer) is a security technology that is commonly used to secure internet transmissions, such as email messages and attachments. SSL does not enable scanning a stack of documents automatically.

Which of the following dot matrix printer components converts impulses into physical movements that cause small hammers to strike the printhead?

An electromagnet converts the impulses into physical movements, causing small hammers to appropriately strike the printhead. The logic board generates a series of electric impulses that are sent to the electromagnet. A daisy wheel is a type of impact printer printhead. A tractor feed helps ensure that continuous paper is fed through the printer at a consistent rate.

You have just installed a new CPU in your workstation along with a CPU heat sink and fan. Which of the following should you do next as a best practice?

As a best practice, you should update the BIOS shortly after installing a processor (you must have a processor and memory installed to update the BIOS). Ensuring that the CPU and motherboard socket type matches is a step that you should complete before you install the CPU. Verifying that the motherboard supports the processor speed is another step that you should complete before you install the CPU. Connecting the fan's power supply is a step that you should complete as part of the fan installation.

You have just purchased a new plug-and-play sound card on your Windows workstation that uses a PCI slot. You've updated the sound card driver and installed the apps that came with the card. You decide to play some songs located on your hard drive using a third-party app that you've installed. However, there is no sound coming out of your headphones or speakers. You've checked the Sound applet and the Sound Properties dialog from Control Panel and the volume settings to make sure the settings are correct. You've also tried playing a few system sound files on your workstation, as well as YouTube videos, and the sound is coming through the headphones and speakers. What should you do next to try and resolve the issue?

Because the problem has to do with some sound files playing correctly, while others do not, the most likely issue is that you do not have a codec installed for the format of the song files you are trying to play. You can check System Information for a list of installed codecs. If the needed codec is missing, you will need to find and install it. EMI (electromagnetic interference) would cause the sound card to fail playing all sound (not just selected files). If the sound card is not seated correctly, it would not function at all. Because you are able to hear sound from some files and not others, the sound card is already selected in BIOS (instead of the onboard sound 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?

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.

Match each key printing term on the left to the appropriate description on the right.

Below are the correct definitions for each printing term. Print driver - The software that allows the printer to communicate with the print device. Printer port - The connection point for the print device to connect to a print server. Print queue - The location on the hard disk that holds print jobs waiting to be processed. Print server - The software process that sends print jobs to the print device. Print spooler - The software process that captures print jobs from applications, places them in the print queue, and then sends each print job to the print device.

As an IT network administrator for your financial company, you have decided to set up document scanning services to digitize, store, and share the large number paper-based documents used in financial transactions. You want to be able to store these digitized documents offsite and make them available to all authorized employees from a centralized storage location for mobility and collaboration in real time. Which of the following document scanning solutions MOST closely matches your requirements?

Cloud services most closely match your requirements, as the digitized documents will be stored offsite will be available from a centralized storage location and will provide for mobility and collaboration in real time. Scan-to-email is a network document scanning method that sends scanned documents to individuals or groups via email. While the attached scan documents would be stored by the email service offsite, they are not stored in a centralized location for access by all authorized employees for collaboration in real time. Scan-to-folder is network document scanning method that provides a centralized repository for sharing scanned documents over a network, but the documents are stored locally, and this method does not provide features for collaborating in real time. OCR (Optical Character Recognition) is software that converts hard copy documents into digital information that can then be edited or transformed. OCR is not a scanning or storage solution.

You want to configure your computer so that a password is required before the operating system will load.

Configuring a user password in the BIOS/UEFI requires that a valid password is entered before the operating system will load. When an administrative password is set, it must be entered in order to access the firmware setup program. Chassis intrusion detection helps you identify when a system case has been opened. Password settings in the Local Security Policy control passwords associated with user accounts that are configured within the operating system. These passwords are used after the system loads the operating system, not before.

Match each USB connector type on the left with the image label on the right. (Not all USB connector types will be used.) (see pages)

Connector 1 is a USB 3.0 Type-A connector. The blue tab indicates that the connector is a USB 3.0 Type-A connector and capable of USB 3.0 speeds. USB 3.0 Type-A connectors are backwards compatible with all previous USB versions. Connector 2 is a USB 3.0 Micro-B connector. The USB 3.0 Micro-B connector is used by portable devices, such as compact external storage devices, digital cameras, or smartphones. Connector 3 is a USB 3.0 Type-B connector. The USB 3.0 Type-B connector is larger in size and designed to carry both data and power. Due to their increased size, USB 3.0 Type-B connectors cannot be plugged into older USB Type-B ports. However, USB 3.0 peripherals that use this port are able to accept older USB Type-B connectors. Connector 4 is a USB 2.0 Type-A rectangular connector that generally plugs directly into the computer or a hub. Almost all USB cables have one Type-A connector on one of the ends.

Which of the following are printer languages? (Select three.)

Escape codes were used by early printers. Hewlett-Packard's Printer Control Language (PCL) and Adobe PostScript are two common printer languages for modern printers. PrintDef refers to the printer definition and is not a printer language. Capture is a Windows feature that allows you to capture video of your screen. Pascal is a procedural programming language that supports structured programming and data structures to encourage good programming practices.

Which of the following describes how a printer communicates when it is connected by an Ethernet cable?

Ethernet printers communicate through the network router or hub using a cable and interface card. Wired printers communicate with one computer using a cable connected through the USB port. Legacy printers communicate with one computer using a cable through a dedicated serial or parallel printer port on older computers. Wireless printers communicate through radio frequency technologies.

You have been using the same computer for several years. To improve performance, you decide to upgrade the processor. You check the motherboard documentation and purchase the fastest processor that is supported by the motherboard. However, when you try to start the computer, it beeps regularly, and nothing is displayed on the screen. Which of the following actions will MOST likely resolve this issue? (Select two.)

Flashing the BIOS or UEFI firmware is often required to upgrade system components, such as upgrading to a faster processor. If the motherboard documentation lists the processor as supported, but the processor is not correctly recognized, updating the BIOS or UEFI firmware to the latest version might fix the problem. Before you can do this, you must reinstall the old processor in the system to get the system back up and running again. Only replace the CPU if you have determined that the CPU is faulty. Pressing F8 while booting the system displays the advanced boot menu on older versions of Windows. Replacing the motherboard is probably not required because the motherboard was working correctly with the older CPU, and the documentation indicates that the new CPU is compatible.

You are in the process of building a new computer. You would like to configure your computer to use Crossfire to improve performance when playing your favorite game. Which of the following should be part of the configuration process?

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, the linked video cards must be identical. HDCP is a copy-protection method that prevents playback of protected content (such as movies on Blu-ray discs) on devices that do not support HDCP. HDMI is used to connect a computer to a high-end monitor or television. DVI is used to connect a computer to a monitor.

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.)

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.

You are building an HTPC (home theater PC) that will be connected to an HDTV. You want to be able to play Blu-ray movies on the HTPC. Which of the following features should your video card and HDTV MOST likely support?

High-bandwidth digital content protection (HDCP) is a method for protecting digital media, such as Blu-ray movies, from being intercepted and copied. When playing protected content from a PC, the optical device, video card, and external display must all support HDCP. Both DirectX and OpenGL are API collections that are used to improve graphic, animation, and multimedia creations. HDTV is a high-definition signal used to broadcast digital TV signals.

What is the best way to set up a Wi-Fi-incompatible printer to provide the most reliable wireless printing?

If a printer is not Wi-Fi-capable but it has an Ethernet port, connect the printer to a wireless router with an Ethernet cable. Users on the same network as the wireless router will be able to send jobs to the printer as if the printer had a wired connection. (All users will have to install that printer's driver on their workstations.) Bonjour can only be used for wireless printing through a Wi-Fi connection. A USB wireless adapter will not provide a wireless connection for a printer because the adapter needs to be connected to a device with an operating system and the capacity to install drivers. The wireless router option is more reliable than connecting the printer to a workstation that has a wireless connection to the network and then sharing the printer from that workstation. The workstation performs the same role as the wireless router, but the workstation will shut down more often than the wireless router would.

When an Inkjet printhead fails, you can often solve the issue by cleaning the printhead. Which of the following issues MOST likely indicates that cleaning the printhead is the solution to a printhead failure?

If a specific color is not printing, cleaning the printhead is the most likely solution. Failure of the carriage to move the printhead back and forth during a print job does not indicate the blockage of a print color. The rollers tightly pinch the paper and move through the printing process. A failure of the rollers to advance the paper does not indicate the blockage of a print color. The duplexing assembly is an optional printer attachment that automatically turns over the paper and reroutes it back through the printer for two-sided printing. Failure of the duplexing assembly to work properly does not indicate the blockage of a print color.

Which of the following BEST describes the Raster Image Process (RIP) for a document in a laser printer?

In a laser printer, the document passes through the Raster Image Process (RIP), which is divided into horizontal raster lines of organized dots as characters, words, and graphic images. The imaging process of exposing includes causing a neutralized electrical charge where the laser light has written. The imaging process of developing includes laying down the toner. The toner is attracted to the imaging drum where the laser wrote the image. The imaging process of transferring includes transferring the toner image on a drum to the negatively charged paper.

Your system administrator shared a USB laser printer connected to your Windows 11 system so other users on the network could send jobs to it. A network user has sent a large job to the printer, but the print job has stalled. You try to delete the print job, but can't. Which of the following BEST describes the reason you cannot delete the print job? Answer

In this case, you can't delete the print job because you don't have the Manage documents permission. Users who have the Manage documents permission can manage all documents in the queue (pause, resume, delete, or rearrange the order). Users with the Print permission can print using the printer and manage their own documents. Users with the Manage this printer permission can edit the printer properties and pause the printer, but cannot manage any documents waiting to be printed. The Manage network printers permission does not exist.

You have purchased a new notebook. This notebook system uses UEFI firmware and comes with Windows 11 preinstalled. However, you want to use Linux on this system. You download your favorite distribution and install it on the system, removing all Windows partitions on the hard disk in the process. When the installation is complete, you find that the operating system won't load when the system is rebooted. Which of the following would allow your computer to boot to Linux?

In this scenario, you should disable the SecureBoot option in the UEFI configuration. SecureBoot requires the operating system installed on the hard drive to be digitally signed. If it isn't digitally signed, the UEFI firmware will not boot it by default. Reinstalling Windows 11 does not meet the requirements of this scenario. If SecureBoot is already enabled, the TPM chip on the motherboard must already be enabled as well. The boot order configuration is not preventing the system from booting in this scenario.

A customer would like you to install a high-end video card suitable for gaming. Which of the following should the installation and configuration include? (Select three.)

It is critical that you always ensure that the video card is compatible with the expansion slot the video card will be installed in. In addition, you should configure the PC to use the integrated graphics and install and update the video drivers from the included CD. You do not link the integrated graphics to the new video card using a bridge clip. You use a bridge clip to link two identical graphics cards inserted into PC slots. In some cases, you may have to disable the integrated graphics. However, if possible, you should configure the computer to default back to the integrated graphics if the new high-end graphics card fails or is removed. Otherwise, you may not be able to access the BIOS/UFI firmware to change the computer back to the integrated graphics. Some high-end graphic cards may require a connection to the power supply, but you do not need to disable power to the integrated graphics. You typically only need twice as much system memory as your graphics car has VRAM. Since this computer has 16 GB of RAM, and the card is only 4 GB, no additional RAM is required.

Which statements are true of processor caches? (Select two.)

Level 1 (L1) cache is integrated on the processor die itself and is typically unique to the processor core on multi-core systems. Level 3 (L3) cache is shared between all cores. The size of the cache increases as you move from L1 to L3, with L1 cache being the smallest. All three cache levels are located on the processor. As a general rule, a processor with more cache performs better than a processor with less cache (all other things being equal).

Which of the following actions does an ATX power supply perform? (Select two.)

Power supplies are responsible for powering every component in a computer system. Power supplies: Convert AC power to DC power. Provide internal components with 3.3 V, 5 V, or 12 V of DC power. Aid in thermal management. Surge protectors are used to protect power supplies and electronic components from power spikes. A UPS (Uninterruptable Power Supply) provides backup power to a computer.

You have an AMD processor and an Intel processor, both of which have the same speed rating. Which of the following statements is true about the relative performance of both processors?

Processor performance is dependent on the chip's specifications, not on the manufacturer or even the speed rating. Other factors, such as the amount of cache, have a greater impact on performance than does the processor speed.

Stereolithography (SLA) is considered the first 3D printing process. Which of the following components does SLA use to create a three-dimensional object? (Select two.)

The 3D printing method that is called stereolithography (SLA) uses a laser beam of ultraviolet light to build a 3D object on a moveable build platform that is submerged in a vat of liquid resin. Fused deposition modeling (FDM) is a 3D printing method that uses an extruder assembly and filament that is threaded into a moveable printhead.

Which of the following objects is installed between the back side of the system case and the motherboard's ports?

The I/O shield (also called a faceplate) is placed between the motherboard and the system case. The shield protects the case from dust and debris. Standoffs are placed between the motherboard and the case and prevent the motherboard circuits from touching the system. Fans are installed in the system case, but not between the system case and the back I/O panel. Heat spreaders are placed on memory modules to help cool them.

To use EDB, the processor must have EDB capability and an operating system that supports EDB capability. A "J" after the CPU model number indicates EDB-enabled Intel processors. Memory, motherboards, and the bus do not need to have any special support for EDB.

The best solution in this scenario is to upgrade the workstation cooling devices to compensate for the additional heat that is generated by overclocking. While you should adjust the motherboard bus, processor, and memory settings to match the overclock speed, this step does not resolve the overheating issue. You can reset the clock time back to its original setting to reduce the amount of generated heat, but resetting the clock does not resolve the issue with the additional heat that is generated by overclocking. Running a benchmark test gives you information about the speeds of the processor, graphics card, storage drives, and memory. However, a benchmark test does not resolve the issue of the additional heat that is generated by overclocking

The sound card in your new Windows workstation includes a connector (see illustration below) for digital audio. What is the port type for this connector? (see pages)

The connector port type is a TOSLINK (or optical audio cable) connector used with digital optical I/O for Sony/Philips Digital Interface (S/PDIF) audio. RCA (Radio Corporation of America) port types use coaxial digital I/O for S/PDIF audio. Some sound cards include one or more IEEE 1394 (FireWire) ports. These ports function as normal IEEE 1394 ports. A sound card with an HDMI port can send high-definition audio to an HDMI device.

Which of the following are common digital audio file types? (Select three.)

The following are common digital audio file types: WAV (Waveform Audio File Format) - a widely used and compatible file type. It is proprietary to Microsoft. AIFF (Audio Interchange File Format) - the Macintosh equivalent of WAV. WMA (Windows Media Audio) - a highly compatible standard that was developed to compete with Real Audio. JPEG and PNG are graphic file types. MP4 and MOV are movie file types.

Which of the following BEST describes the purpose of the north bridge chipset?

The north bridge is the chip that connects a CPU to memory, the PCI bus, Level 2 cache, and AGP activities. The north bridge chip sits near the CPU and communicates with the CPU through the front-side bus (FSB). The other options are functions of the south bridge chipset.

Which of the following allows a computer to communicate with a printer?

The print driver is the software that allows the computer to communicate with the printer. The print queue is the portion of the hard drive where print jobs are stored before going to the printer. The printer port is the means by which a printer connects to a print server. The print spooler is a Windows service that captures print jobs from applications, places them in the print queue, and then sends each print job to the print device.

Which of the following BEST describes the print queue?

The print queue is the location on the hard disk that holds print jobs that are waiting to be processed. A print server is the process that manages the flow of print requests for how and when documents are sent to the printer. The print driver is the software that allows the printer to communicate with the print device. The print spooling service captures print jobs from an application, holds them in a queue, and then sends each job to the print device.

Which of the following statements are true? (Select two.)

The processor instruction set identifies all instructions (operations) that a processor can perform. 32-bit processors use the IA-32 instruction set (also referred to as x86). Itanium processors from Intel use the IA-64 instruction set. AMD64 and Intel 64 processors use the x86-64 instruction set (also referred to as x64). 32-bit applications can run on 64-bit processors. x64 processors execute both 32-bit and 64-bit instructions in the hardware. There are no settings in BIOS/UEFI for making sure that 32-bit applications can run on 64-bit processors.

Regular cleaning of your thermal printhead prevents you from having to replace the printhead often. Which of the following describes the recommended procedure to remove carbon buildup and adhesives from a thermal printhead?

The recommended procedure for cleaning your thermal printhead is to wipe it with isopropyl alcohol on a lint-free cloth or cotton swab to remove carbon buildup and ribbon dust that may collect over time. Clean a laser printer drum by running 10 to 15 blank pages. Clean an Inkjet printhead with water. Some Inkjet printers have a Clean Printhead function, but this function does not normally exist for a thermal printer.

Which component in a laser printer charges the paper to attract toner?

The transfer roller charges the paper to attract the toner. The primary corona prepares the photosensitive drum for writing by causing the drum to receive a negative electrostatic charge. Depending on the printer, the primary corona is either wires or rollers. A laser beam changes the charge on the surface of the drum in a pattern of the page's image. The toner sticks to the charged areas on the drum. Fusing rollers attach the toner to the paper by pressing and melting the paper.

You have just installed a new capture card and software on your workstation. Which of the following is the kind of capture card that you MOST likely installed?

There are different kinds of capture card types based on video quality. One of the most common is OBS, which stands for Open Broadcaster Software. USB and PCIe are hardware standards for connecting and interfacing with a video card. Video encoders are the engine that converts video format so that it can be delivered to a file type, such as MP4.

Which of the following is the feed assembly on a thermal printer that is used to move the paper through the printer?

Thermal printer technology is simple. The feed assembly is a rubber roller, or platen, that grabs the paper and passes it through the printer. A spring device applies pressure to the paper so that the paper always touches the printhead as it passes through. The unwind spindle only holds a roll of labels or paper and does not move. A thermal printer does not have a stepper motor like an Inkjet printer. A thermal printer does not have a paper feeder like a dot matrix printer.

Which of the following is the type of printer that uses pins as tiny heating elements to produce an image on the paper?

Thermal printers use a printhead that is made of rows of many tiny pins that are like miniature heating elements. Inkjet, laser, and dot matrix printers use a variety of methods to produce images on paper (such as dots of ink on the page), but these types of printers do not use a thermal printhead with heating elements.

Which of the following ensures that thermal transfer prints (prints from a thermal printer) are durable?

Thermal transfer printers use heated pins to transfer solid ink that is made of wax or resin composite from a ribbon. After the ink is melted onto stock material, the ink becomes very durable. Thermal paper provides a coating that is heat-sensitive to the pins in a thermal printer, which produces the printout.

You want to restrict the hours that the QA printer is available from Windows. Which tab on the Printer Properties page would you click so that you can restrict the hours that the printer is available? (see pages)

To configure when a printer is available, edit the settings on the Advanced tab on the Printer Properties page.

To fix a problem you are having with your PC, you have determined that you must flash the computer's BIOS. Which of the following would MOST likely need to be completed prior to flashing the BIOS? (Select two.)

To successfully flash your BIOS, it is critical that you research and know the exact make, model, and revision of your motherboard to ensure that the correct flash file is used. Using the wrong flash file will probably cause errors. Although your computer may have shipped with a tool to perform a BIOS flash, it is best to download the latest tool to ensure that the flash is performed correctly. Testing the memory and creating a hard backup will not aid you while flashing a PC's BIOS.

You want to enable the Execute Disable Bit (EDB) setting in your BIOS/UEFI to help reduce your system's exposure to viruses and malicious code. Which of the following are requirements for your system to use EDB? (Select two.)

To use EDB, the processor must have EDB capability and an operating system that supports EDB capability. A "J" after the CPU model number indicates EDB-enabled Intel processors. Memory, motherboards, and the bus do not need to have any special support for EDB.

Which of the following are benefits UEFI provides that BIOS does not? (Select three.)

UEFI provides the following benefits over BIOS. UEFI: Has faster startup times. Supports drives larger than 2.2 terabytes. Supports 64-bit firmware device drivers. Provides better security to protect against bootkit (malware attacks on the boot process) attacks. Similar to BIOS, UEFI does need to be flashed in order for updates to make new features available on the computer. EEPROM is the technology that provides non-volatile memory and allows individual bytes to be erased and reprogrammed.

You have just purchased a new computer. This system uses UEFI firmware and comes with Windows 11 preinstalled. You recently accessed the manufacturer's support website and saw that a UEFI firmware update has been released. You download the update. However, when you try to install it, an error message is displayed that indicates the digital signature on the update file is invalid. Which of the following MOST likely caused this to happen?

UEFI requires firmware updates to be digitally signed by the hardware vendor. Using digital signatures, unauthorized changes to firmware updates (such as the insertion of malware) can be detected. The SecureBoot feature requires that operating systems be digitally signed before they can be booted. The latest UEFI update most likely includes all of the changes that were implemented in earlier updates. There is no indication that the system has been infected with rootkit malware in this scenario.

Which printer management features would you use to view the port that a printer uses? (Select two.)

Use Print Server Properties or Printer Properties to view the port(s) that a printer uses. Print Server Properties displays the printer port(s) that a system uses. Printer Properties displays the port(s) for the individual printer as well as all printer ports for the system. The print spooling service is the software process that captures print jobs from applications, places them in the print queue, and then sends each print job to the print device. The print queue is the location on the hard disk that holds print jobs that are waiting to be processed.

Match each video card type on the left with the appropriate characteristics on the right. Each video card type is used more than once.

Video cards process graphical information for output to an external display. Video cards can be implemented as a dedicated expansion board or integrated with other components (such as the motherboard or CPU). Dedicated video cards: Are installed in an expansion slot on the motherboard. Have a GPU and a dedicated high-speed video memory bank. Are more powerful than integrated video cards, but are also more expensive. Integrated video cards: Integrate the GPU with another hardware component (such as a motherboard or CPU). Share system memory for graphic processing. Are much cheaper than dedicated video cards, but are also less powerful.

From the illustration below, select the sound card port that can be used for both analog and digital audio. (see pages)

While you can use RCA ports for analog audio, RCA ports on a sound card are normally used for S/PDIF digital audio. HDMI, TOSLINK, and Mini TRS ports are used for digital audio sound.

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?

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.

You just got a new monitor for your computer. After using it for a few days, you notice that you have more eye strain and are getting headaches. Which of the following monitor changes would MOST likely reduce or eliminate your symptoms?

Your headaches and eye strain are most likely caused by the flickering of your new monitor. Flickering is often caused by a low refresh rate measured in hertz. To remove the flickering, increase the refresh rate. Note that the refresh rate you can set for your LCD monitor is largely determined by your monitor's capabilities and the driver being used. The most common refresh rate is 60 hertz. Changing the resolution may change the size of the information being displayed and may increase eye strain. Regardless of the resolution, flickering will still occur. Decreasing the refresh rate would cause more flicker. Changing the orientation will change how the information is viewed, but will not help solve a flicker issue.
