A system with only 1 GB RAM might be underpowered, but that in and of itself does not make it a legacy system

Internal users suspect repeated attempts to infect their systems, as reported to them by pop-up messages from their antivirus software. According to the pop-up messages, the virus seems to be the same in every case. What is the most likely culprit? A. A server is acting as a carrier for a virus. B. A password attack is being carried out. C. Your antivirus software has malfunctioned. D. A DoS attack is underway.

A. A server is acting as a carrier for a virus. Some viruses won't damage a system in an attempt to spread into all the other systems in a network. These viruses use that system as the carrier of the virus. A password attack would not prompt your antivirus software to notify you. Your antivirus software could be malfunctioning, but it would not suggest the same virus is infecting you over and over again. A denial-of-service (DoS) attack would not prompt your antivirus to notify you.

Which type of attack is most likely occurring? A. Brute-force B. Backdoor C. Worm D. TCP/IP hijacking

A. Brute-force A brute-force attack is a type of password attack in which a password is guessed over and over, until the right password is guessed. A backdoor attack is an embedded account that allows unauthorized access through an unpatched coding hole. A worm is different from a virus in that it can reproduce itself, is self-contained, and doesn't need a host application to be transported. A TCP/IP hijacking attempt is an attack that attempts to redirect the TCP/IP conversation to the threat agent.

What is the lowest grade of UTP that is rated for 100 Mbps transmission? A. CAT-5 B. CAT-5e C. CAT-6 D. CAT-6a

A. CAT-5 CAT-5 was the first UTP standard ratified for 100 Mbps transmissions. Before that, CAT-3 was popular but only supported 10 Mbps. CAT-5e, CAT-6, and CAT-6a all support at least 1 Gbps and came after CAT-5.

When you turn on a desktop computer, you hear a loud squealing noise coming from inside the case. Which components are potential culprits for making the noise? (Choose all that apply.) A. CPU fan B. Power supply fan C. HDD D. SSD E. CPU F. RAM

A. CPU fan B. Power supply fan C. HDD Only components with moving parts can make ticking, clicking, or squealing noises. It's probably a fan of some sort (such as the CPU fan or power supply fan), or it could be a conventional hard drive. SSDs, CPUs, and RAM do not have moving parts and therefore could not be causing this problem.

You have just installed a wireless router on your home network. Which of the following should you do to make it highly secure? (Choose all that apply.) A. Change the default administrator name and password. B. Change the SSID. C. Enable WEP. D. Configure it to channel 11.

A. Change the default administrator name and password. B. Change the SSID. You should always change the default administrator name and password as well as the default SSID when installing a new wireless router. Enabling encryption is also a good idea, but WPA and WPA2 are better options than WEP. The channel has nothing to do with security.

Which of the following is used to attach media connectors to the ends of cables? A. Crimper B. Cable stripper C. Multimeter D. Tone generator

A. Crimper Wire crimpers look like pliers but are used to attach media connectors to the ends of cables. A cable stripper is used to remove the outer covering of the cable to get to the wire pairs within. A multimeter combines a number of tools into one. There can be slight variations, but a multimeter always includes a voltmeter, an ohmmeter, and an ammeter (and is sometimes called VOM as an acronym). A toner probe has two parts: the tone generator (called the toner) and the tone locator (called the probe). The toner sends the tone, and at the other end of the cable, the probe receives the toner's signal. This tool makes it easier to find the beginning and end of a cable.

You are setting up a small network that will not connect to the Internet. You want computers to be able to locate each other by using hostnames. What service will do this? A. DNS B. DHCP C. FTP D. APIPA

A. DNS DNS is typically known as a name resolver on the Internet, but it will work on private networks as well. DNS resolves hostnames to IP addresses. DHCP automatically configures clients with IP address information. FTP is for file downloads. APIPA is a process used to assign clients a private IP address automatically when they can't reach the DHCP server.

You are setting up a small office network for a client. Which Internet service would you recommend to provide the best speed? A. DSL B. Dial-up C. Satellite D. BRI ISDN E. PRI ISDN

A. DSL Of the options listed, DSL provides the fastest speed. DSL can easily provide 12 Mbps downloads. Dial-up is limited to 56 Kbps, and BRI ISDN (128 Kbps) and PRI (about 1.5 Mbps) don't even come close. Satellite is also much slower than DSL.

You are manually configuring a TCP/IP host. Another administrator gives you the router's IP address. What is the TCP/IP term for this? A. Default gateway B. Subnet mask C. DNS server D. DHCP server

A. Default gateway The router is your doorway out into other networks, and it is known in TCP/IP terms as the default gateway. Without this configuration option, you would not be able to get to external networks. The subnet mask tells a host which network it's on. The DNS server resolves hostnames to IP addresses, and a DHCP server provides IP configuration information to hosts.

Which of the following utilities will rearrange the files on your hard disk to occupy contiguous chunks of space? A. Disk Defragmenter B. Windows File Explorer C. Scandisk D. Windows Backup

The interpreter in Linux between the operating system and the user is known as the ____________. A. Shell B. Translator C. Login D. GUI

A. Shell The shell is the interpreter in Linux between the operating system and the user. The translator is a wrong answer. Login is something you perform to access the shell. The graphical user interface (GUI) does not interpret commands and therefore not considered an interpreter.

As part of your training program, you're trying to educate users on the importance of security. You explain to them that not every attack depends on implementing advanced technological methods. Some attacks, you explain, take advantage of human shortcomings to gain access that should otherwise be denied. Which term do you use to describe attacks of this type? A. Social engineering B. IDS system C. Perimeter security D. Biometrics

A. Social engineering Social engineering uses the inherent trust in the human species, as opposed to technology, to gain access to your environment. IDS systems are network-based systems that detect intrusions. Perimeter security describes physical security. Biometrics describes an authentication method based on human physical traits.

A junior administrator comes to you in a panic. After looking at the log files, he has become convinced that an attacker is attempting to use a legitimate IP address to disrupt access elsewhere on the network. Which type of attack is this? A. Spoofing B. Social engineering C. Worm D. Password

A. Spoofing A spoofing attack is an attempt by someone or something to masquerade as someone else (IP address) and is often used to disrupt access. Social engineering is a process in which an attacker attempts to acquire information about your network and system by social means, such as talking to people in the organization. Worms reproduce and move throughout the network to infect other systems. Password attacks are used in an attempt to guess passwords.

You have a very small network in a home-based office, and you want to limit network access to only those hosts that you physically own. What should you utilize to make this possible? A. Static IP addresses B. Disabled DNS C. Default subnet mask D. Empty default gateway

A. Static IP addresses The advantage to assigning the IP addresses statically is that you can make certain which host is associated with which IP address, and then utilize filtering to limit network access to only those hosts. Disabling DNS will limit all hosts on a network from getting to the Internet and will not limit network access. A default subnet mask will not limit network access and will cause other problems. An empty default gateway will not limit network access.

Which feature allows you to recover the operating system to a prior point in time after you installed a faulty application or driver? A. System Restore B. Snap C. WinPE D. BOOTMGR

A. System Restore The System Restore feature allows you to recover the operating system to a prior point before the faulty application or driver was installed. Snap is a function of the Desktop interface that allows for easy resizing of Windows. WinPE is a preinstallation environment used for upgrading or installing Windows. BOOTMGR is the bootstrap program responsible for selecting the operating system on startup.

D. The storage might go unused. Allocating too much storage for an application might mean that the storage never gets used. Allocating too much storage has no effect on how fast storage gets filled. Storage might need to be downgraded in the future, not upgraded. It is not likely for another application to use the space that was originally allocated for a different application.

Which of the following makes it easier to find the beginning and end of a cable? A. Crimper B. Cable stripper C. Multimeter D. Tone generator

D. Tone generator A toner probe has two parts: the tone generator (called the toner) and the tone locator (called the probe). The toner sends the tone, and at the other end of the cable, the probe receives the toner's signal. This tool makes it easier to find the beginning and end of a cable. Wire crimpers look like pliers but are used to attach media connectors to the ends of cables. A cable stripper is used to remove the outer covering of the cable to get to the wire pairs within. A multimeter combines a number of tools into one. There can be slight variations, but a multimeter always includes a voltmeter, an ohmmeter, and an ammeter (and is sometimes called VOM as an acronym).

Your friend Joe plays video game tournaments online, and he read in an online forum that he should install multiple GPUs for better speed. You tell him that if he does that, he needs better cooling. Why is high-end cooling a requirement for gaming PCs? A. Multiple GPUs generate more heat and can cause components to fail. B. Gaming controllers have components for tactile realism that generate copious amounts of heat. C. Digital sound cards generate more heat than analog sound cards. D. Placing that many hard drives in such a small space generates too much heat.

A. Multiple GPUs generate more heat and can cause components to fail. Multiple video cards (to get multiple GPUs) can be a way to increase video performance. Such a configuration may generate too much heat for conventional cooling to dissipate before the system is damaged. The cooling has no effect on external controllers, and sound cards don't generate much heat, but analog would certainly generate more than digital.

All of the following systems benefit from increased RAM except ___________________. (Choose two.) A. Network-attached storage device B. Virtualization workstation C. Graphic design workstation D. Gaming PC

A. Network-attached storage device D. Gaming PC Virtualization and graphic design workstations benefit from as much RAM as can be installed. Network-attached storage devices and gaming PCs do not require a large amount of temporary storage of instructions and data. They are more about the rapid movement of graphical data toward an output device.

Your Core i5 fan has a four-pin connector, but your motherboard only has a single three-pin header with the CPU_FAN label. Which of the following will be the easiest solution to get the necessary cooling for your CPU? A. Plug the four-pin connector into the three-pin header. B. Buy a four-pin to three-pin adapter. C. Leave the plug disconnected and use only the heat sink. D. Add an extra chassis fan.

A. Plug the four-pin connector into the three-pin header. The easiest solution that works to cool your CPU is to connect the four-pin connector into the three-pin header. The missing pin allows you to control the speed of the fan. Without it, the fan will run at top speed, which is fine, albeit a little noisier. There is no four-pin to three-pin power adapter. The heat sink alone should not be relied upon for proper cooling of modern CPUs, and an extra chassis fan isn't designed to specifically help cool the CPU.

Which of the following best describes the concept of hot-swappable devices? A. Power does not need to be turned off before the device is inserted or removed. B. The device can be removed with power applied after it is properly stopped in the operating system. C. Care must be taken when swapping the device because it can be hot to the touch. D. The device can be swapped while still hot, immediately after powering down the system.

A. Power does not need to be turned off before the device is inserted or removed. Hot-swappable devices can be removed while the power to the system is still on. Warm-swappable devices need to be stopped in the operating system before being removed. The term has nothing to do with the heat level of the device.

Marcus, a network technician, has been asked to build a virtualization workstation for his manager. Which of the following are not common requirements that Marcus should consider for this custom configuration? (Choose all that apply.) A. Surround sound B. Maximum RAM C. Large, fast hard drives D. Multiple CPU cores

A. Surround sound C. Large, fast hard drives Virtualization workstations need to maximize the amount of RAM as well as CPU cores. Each virtualized instance of an operating system will be assigned its own memory and processor resources, and those resources are essentially reserved and off-limits to other virtual operating systems. Therefore, maximize both of them. Audio isn't required on a virtualization workstation, so surround sound is not needed. Large fast hard drives will be nice but are not a primary requirement.

Due to government regulations, a client wants to preserve data for a long period of time. What kind of media is most commonly used when large amounts of data need to be archived on a regular basis? A. Tape B. Optical disc C. External hard drive D. Network share

A. Tape Although inefficient as an interactive medium, sequential tape-based storage continues to be developed in increasing capacities. Tape continues to be a good choice for frequently backing up large amounts of data for redundancy and archival purposes. Optical discs don't have the same capacity, and neither do external hard drives. The cloud could be an option, but that is different from a network share.

You are interested in purchasing a new monitor and notice the contrast ratio specification. What does that refer to? A. The ratio of luminance between the darkest and lightest colors that can be displayed B. A term that was used with LCDs but is not a valid specification for OLEDs C. The ratio of luminance between two adjacent pixels D. A feature that changes based on the resolution setting

A. The ratio of luminance between the darkest and lightest colors that can be displayed Contrast ratio is a selling point for LCDs and is relevant for all monitor types, including OLEDs. Higher contrast ratios mean the monitor displays darker blacks and brighter whites. The measure of luminance between adjacent pixels is known as contrast, not contrast ratio. Contrast ratio is not dependent upon resolution.

A video editor at your company wants a second monitor, claiming that having only one monitor limits her ability to work. Why do A/V editing workstations benefit from more than one monitor? A. Their software often has enough controls across their width that one monitor seems cramped. B. While one graphics adapter works on one rendering project, the other can simply display a normal desktop. C. Once the editing is complete, the second monitor is used to present the results to others on the team. D. Additional monitors are used for remote collaboration among other editors.

A. Their software often has enough controls across their width that one monitor seems cramped. Editors of this type of media have numerous controls and timelines to track. These constructs often lie along the bottom of the application and run horizontally. Subsequent monitors allow the editor to spread out her work without shrinking the view excessively.

Which of the following display interfaces is equivalent to DisplayPort with PCIe added in? A. Thunderbolt B. HDMI C. DVI D. VGA

A. Thunderbolt Intel and Apple collaborated on Thunderbolt to add PCIe to VESA's DisplayPort and to make the resulting interface smaller and less expensive to connect. HDMI, DVI, and VGA are not equivalent to DisplayPort with PCIe added in.

When installing multiple add-on cards of the same type, which type of cards might you need to bridge together to function as a single unit? A. Video B. Sound C. USB D. eSATA

When replacing a power supply, which of the following tends to vary among power supplies and must be chosen properly to support all connected devices? A. Wattage B. Voltage C. Amperage D. Resistance

A. Wattage Power supplies are rated in watts. When you purchase a power supply, you should make sure the devices inside the computer do not require more wattage than the chosen power supply can offer. The voltage is fairly standard among power supplies, and it has nothing to do with the devices connected to the power supply. Amperage and resistance are not selling points for power supplies. Another thing that could vary is the number of power connectors—make sure the new power supply has enough to support all installed peripherals.

Which of the following allows you to navigate file⁄folder structures in Windows 10? A. Start menu B. File Explorer C. KDE D. GNOME

B. File Explorer The File Explorer allows you to navigate the file⁄folder structure in Windows 10. The Start menu allows you to launch applications. KDE and GNOME are Linux desktop shells.

Which of the following is a program that runs on top of the OS and allows the user to issue commands through a set of menus or some other graphical interface? A. Taskbar B. Shell C. Desktop D. Source

B. Shell The shell is a program that runs on top of the OS and allows user interaction with the operating system. The taskbar is an element of the Desktop. The Desktop does not allow for commands to be executed. Source is not related to the graphical interface.

B. Copy and move files C. Change file attributes The Windows File Explorer program can be used to copy and move files. Window File Explorer can also be used to change file attributes. Windows File Explorer cannot be used to browse the Internet or to create backup jobs.

You need to replace memory in a desktop PC and to go purchase RAM. When you are at the store, you need to find the appropriate type of memory. What memory chips would you find on a stick of PC3-16000? A. DDR-2000 B. DDR3-2000 C. DDR3-1600 D. PC3-2000

B. DDR3-2000 Remember the 8:1 rule. Modules greater than but not including SDR SDRAM are named with a number eight times larger than the number used to name the chips on the module. The initials PC are used to describe the module; the initials DDR are used for the chips; and a single-digit number after PC and DDR is used to represent the level of DDR. The lack of a single-digit number represents DDR as long as the number that is present is greater than 133 (such as PC1600). Otherwise, you're dealing with SDR (such as PC133). This means that PC3-16000 modules are DDR3 modules and are populated with chips named DDR3 and a number that is one-eighth of the module's numeric code: 2000.

Danielle has been asked to configure virtualization at her company. She recommends that her manager buy multicore processors. What justification should she give as to why virtualization workstations require as many CPU cores as possible? A. Each virtual machine has one or more cores installed directly in it. B. Each virtual machine makes use of actual CPU resources for processing instructions and data. C. Fault tolerance dictates that if one CPU core fails, there should be one or more in line to take its place. D. Because each guest operating system runs in its own space, multiple cores are required to store the collective data.

B. Each virtual machine makes use of actual CPU resources for processing instructions and data. Virtual machines do not imply virtual processing. The data storage, processing cycles, and RAM usage are all real. The separate hard drive and chassis for each operating system are virtual. The other answers all have at least one fundamental problem with their logic. CPU cores are not installed in virtual machines but in CPU packages within physical machines. CPU cores do not take over for each other. There is no fault tolerance among them. Storing data is the job of RAM, which should also be maximized for virtualization workstations.

Which of the following have been common methods to backlight an LCD monitor? (Choose two.) A. RGB OLEDs B. LEDs C. Incandescent bulbs D. Halogen bulbs E. Fluorescent bulbs

B. LEDs E. Fluorescent bulbs Early LCD monitors featured one or more fluorescent bulbs that were used to produce light that shone through the LCD panel. Modern LCD monitors have LED panels to generate the light, the advantage being that there is now a separate LED for each picture element instead of a common light source for the entire monitor. OLEDs do provide light, but RGB OLEDs are not used. Incandescent and halogen bulbs are not used for backlighting

B. Maximum RAM A NAS should support file sharing and media streaming, and have a Gigabit NIC card and a RAID array. Additional RAM in a NAS offers no advantage for the performance of the NAS past a certain point. The tasks the NAS is asked to perform do not require high performance.

You are configuring a virtualization workstation for your home use. Which of the following is required for your new system? A. Multiple host operating systems B. Maximum RAM allowed C. File sharing services D. Multiple NICs

B. Maximum RAM allowed Maximum RAM and CPU cores are the primary requirements for such systems. Although there are multiple guest operating systems, generally there is but one host to those guests. File sharing may be a service the administrator decides to offer, and multiple NICs might prove advantageous with virtual machines that are popular among the clients, but these workstations do not require either.

Which of the following is not an example of a connector for a standard peripheral input device? A. 1/8" jack B. Molex C. D-sub D. USB

B. Molex Peripherals most often use USB today, but they can also use D-sub connectors (rarely), and audio devices such as microphones and speakers use 1/8" jacks. Molex connectors are power connectors for PATA hard drives and optical drives.

Which of the following system types does not benefit from video enhancements? A. CAD/CAM design workstation B. Network-attached storage device C. A/V editing workstation D. Gaming PC

B. Network-attached storage device CAD/CAM design workstations, A/V editing workstations, and gaming PCs can all benefit from video enhancements. A NAS does not benefit from enhanced video and might not use a monitor at all.

A technician asks you how to get a computer's processor to run faster than it currently does. What is he trying to achieve? A. Hyperthreading B. Overclocking C. Virtualization D. Multicore support

B. Overclocking Overclocking is when someone sets the speed of the processor to run faster than it was rated for. While overclocking can make a computer faster, it can also cause the processor to overheat, and it voids the warranty. Hyperthreading allows for a processor core to handle multiple processes simultaneously. Virtualization is when you create multiple virtual machines on a computer. Multicore means that the processor has more than one core—it's not a configurable option.

You need to install a new video card into a desktop computer. What type of expansion slot is preferred today for high-performance graphics adapters? A. AGP B. PCIe C. PCI D. SATA

B. PCIe PCIe is the newest and fastest slot for video cards. AGP and PCI are legacy technologies. SATA is for hard drives.

In Windows, a deleted file can be retrieved using which of the following? A. My Computer icon B. Recycle Bin C. Control Panel D. Settings app

C. Trackball A trackball is a sort of stationary upside-down mouse that has the ball for movement detection on the top of the device along with the keys. The ball is actuated by the thumb or fingers, not by moving the device along a flat surface or mouse pad. Trackballs are ideal where desk space is limited. Touch pads feature a touch-sensing surface with no ball for movement, while track pad is a more rare term meaning the same.

How do you connect a DVI-A interface on a peripheral to a DVI-D interface on the computer? A. With a DVI-I cable B. With a cable that is terminated on one end with a DVI-A connector and on the other end with a DVD-D connector C. You wouldn't interconnect those two interfaces D. With a standard DVI cable

C. You wouldn't interconnect those two interfaces Such a connection should not be made. DVI-I cables act like universal cables; they can connect two DVI-A interfaces or two DVI-D interfaces with adapters. Natively, they are used to connect two DVI-I interfaces, both of which are configured as either analog or digital. They are unable to convert the analog signal to a digital one, however. Analog and digital DVI interfaces are too disparate to interconnect.

You are choosing a flash standard for a client. They want the smallest flash cards possible. Which standard should you recommend? A. SD B. CompactFlash C. microSD D. miniSD E. xD

C. microSD The smallest of the options is microSD, at 15 mm × 11 mm. Perhaps "micro" gives it away, but that also makes it easy to remember. SD cards are 32 mm × 24 mm. CompactFlash cards are the largest, at 36 mm × 43 mm. MiniSD cards measure at 21.5 mm × 20 mm, and xD cards are 20 mm × 25 mm.

You are installing a new hard drive and want to know if the operating system will be able to support it. What is the largest NTFS volume size supported, assuming a 64 KB cluster size as maximum? A. 1 TB B. 2 TB C. 128 TB D. 256 TB

D. 256 TB A fixed number of clusters is supported by each operating system, leading to a corresponding maximum volume size. If the maximum NTFS cluster size of 64 KB is used, NTFS can support a single-volume size of 64 KB less than 256 TB. When a cluster size of one sector, or 512 bytes (1/2 KB), is used, the maximum volume size reduces to 2 TB. Because of this math, 1 TB and 128 TB are incorrect answers.

Which of the following descriptions most closely matches that of a thin client? A. A high-resolution monitor, keyboard, and mouse B. A computer with a low-profile case C. A laptop D. A dumb terminal with a NIC

D. A dumb terminal with a NIC Although not all thin clients are devoid of local processing capability, some are. High-resolution graphics are not a requirement, but thin clients do require a system unit with a NIC.

You are installing a replacement monitor on a desktop computer. Which of the following is true regarding a monitor's refresh rate? A. As long as the graphics adapter can refresh the image at a particular rate, the attached monitor can accommodate that refresh rate. B. The refresh rate is normally expressed in MHz. C. The refresh rate is normally selected by using the controls on the front panel of the monitor. D. As you lower the resolution, the maximum refresh rate allowed tends to increase.

D. As you lower the resolution, the maximum refresh rate allowed tends to increase. As you lower the resolution, the maximum refresh rate allowed tends to increase. The refresh rate is most often expressed in cycles per second (Hz), not millions of cycles per second (MHz). You must usually select the refresh rate that you want from the display settings dialogs, not through the monitor's built-in menu system, although the monitor can often tell you the refresh rate that you're using. Finally, both the monitor and adapter must agree on the refresh rate you select. If either device does not support a particular refresh rate, such a rate cannot be used.

Which of the following is a common feature of a standard thick client? A. Has enhanced video capabilities B. Has a high-performance hard drive C. Has as much RAM installed as possible D. Can run a full version of Windows

D. Can run a full version of Windows These standard systems do not have any special requirements, only that they can run Windows and desktop applications. Thick clients do not need enhanced video, hard drives, or RAM.

You want to enhance your display capabilities. Which of the following is possible to do with multi-monitor settings? A. Connect multiple monitors to your computer only by using a graphics adapter with two video interfaces. B. Cause two different Desktops to merge onto the same monitor. C. Connect two laptops together so they display the same Desktop D. Display different parts of your Desktop on different monitors.

D. Display different parts of your Desktop on different monitors. The multi-monitor feature allows two monitors to display exactly the same thing (clone) or to extend your Desktop onto the second monitor. There is no need to use one adapter to achieve this result. In fact, the two adapters don't even have to use the same expansion-bus architecture. The two cards must, however, use the same graphics-adapter driver. Multi-monitor settings do not cause two Desktops to merge, nor do they allow two laptops to display the same Desktop.

Which part of the operating system can be described as extremely specific software written for the purpose of instructing the OS on how to access a piece of hardware? A. Source code B. Application C. Kernel D. Driver

D. Driver A driver is specifically written to instruct the operating system to communicate with a piece of hardware. Source code is the original code the software is written in. An application is a program written to perform a specific purpose to interact with the user. The kernel is the core of the operating system.

You must make sure that the voltage selector switch on the back of the power supply is switched to the lower setting if the computer is going to be used in Europe. B. SATA hard drives most often use the same type of power connector that PATA hard drives use. C. Power supplies supply power to ATX-based motherboards with connectors known commonly as P8 and P9. D. Power supplies convert AC input to DC output.

D. Power supplies convert AC input to DC output. PC power supplies accept alternating current (AC) as input and produce direct current (DC) for the internal components. Europe requires the voltage selector switch be set at the higher setting. SATA drives most often use a specific power connector that is not compatible with the Molex connector used by PATA drives. Legacy AT-based motherboards called for P8 and P9 connectors; ATX motherboards have a newer 20- or 24-pin single power connector.

To turn off a Windows 10 operating system gracefully, you should do which of the following? A. Run the turnoff command at a command prompt. B. Turn off the switch and unplug the machine. C. Press Ctrl+Alt+Del. D. Select Start, then the power icon, and then choose Shut Down.

D. Select Start, then the power icon, and then choose Shut Down. In Windows 10, when you click the Start button, a power icon is displayed on the lower left. From the power icon, you can sleep, reboot, or shut down the operating system. There is no command named turnoff. Tuning the power switch off and unplugging the machine are not graceful way to power off the operating system. Pressing Ctrl+Alt+Del alone will not power down the computer.

An engineer on your network is complaining that his CAD workstation is slow and he wants a GPU upgrade. Which of the following reasons is justification for having a powerful video card in a CAD/CAM workstation? A. Only powerful GPUs can stream graphical information efficiently. B. Manufacturing equipment is generally faster than design equipment, which needs faster GPUs to keep up. C. On a CAD system, the CPU defers to the GPU for all system processing requirements. D. The algorithms used in rendering graphics can be GPU-intensive.

D. The algorithms used in rendering graphics can be GPU-intensive. Quite simply, the rendering of 2D and 3D graphics makes use of complex algorithms that need all of the GPU power they can get to remain usable. CAD workstations deal with static images, not streaming video. Manufacturing equipment is generally slower than computers used for the design phase. The CPU still does its job, but CAD workstations call for high-end video, which includes graphics adapters with GPUs often more powerful than the system's CPU.

Why might you use a KVM switch? A. You have multiple Ethernet devices that need to communicate with one another. B. You need to be able to switch the voltage supplied to a particular device. C. You have a printer that is not attached to the network but you want multiple computers to be able to print to it. D. You have more than one server and don't want to buy certain external peripherals separately for each.

D. You have more than one server and don't want to buy certain external peripherals separately for each. KVM switches are ideal when you have multiple computers situated near one another and do not want to commit the extra desk space to each computer having its own keyboard, mouse, and monitor. KVMs are not designed for Ethernet devices or printers, and do not switch voltage.
