127.0.0.1

You have a small home network that uses 192.168.1.0 with the default subnet mask for the network address. The default gateway address in 192.168.1.254, and the router is providing DHCP on the network. The Wrk2 computer has been assigned the IP address of 192. 168.1..55. Which of the following is considered the loopback for the Wrk2 computer?

127.0.0.1 Explanation 127.0.0.1 is the loopback address for any device. This special address means "this host."If you ping the loopback address, the TCP/IP configuration will be tested. A successful test means that TCP/IP is correctly configured on the host. 192.168.1.55 is the current IP address assigned to the host. You can ping this address, but the address is not considered the loopback address. also, to pong the host's IP address, you must first know the address. Pinging the loopback address always tests the current host regardless of its current IP address. 192.168.1.255 is the broadcast address for the network meaning äny host"on the network.

Which of the following is a valid IP address?

172. 16.1.26 2.2.2.2 Explanation A valid IPv4 address consists of 4 8-bit (1 byte) numbers separated by periods. For example, 10.0.0.65. Because they are 8 bits long, these numbers are frequently called octets. Even though we typically express these numbers using decimal notation, it's important to remember that these numbers are binary numbers. The lowest value one of these numbers can have is 00000000. The decimal equivalent for this number is simply 0. The highest value one these numbers can take is 11111111. The decimal equivalent of this number is 255. Therefore, in decimal notation, each octet must contain a number between 0 and 255 inclusively.

In preparation to use your laptop on the airplane as you travel to a conference, you disconnected the USB mouse. However, after removing the external mouse, the cursor drifts consistently to the left side of the screen while using the built-in trackpad and mouse buttons. What should you do?

Access the BIOS/UEFI configuration and disable the USB pointer option. Explanation This issue is frequently seen in notebook systems where both the internal trackpad and an external mouse interface (such as USB or even PS/2) are enabled at the same time in the BIOS/UEFI configuration. Essentially, the two mouse interfaces contend with each other for control of the cursor. This problem can be fixed by disabling the external mouse option in the BIOS/UEFI configuration. If that doesn't work, then you can try updating the trackpad drivers or even replacing the trackpad.

which partition type identified the partition as one that holds the boot loader program used to start the OS?

Active

Which partition type identifies the partition as one that holds the boot loader program used to start the operating system?

Active Explanation The active partition identifies which partition holds the boot loader code. When the system starts, it looks in the volume boot record (VBR) of the active partition to identify the location of the boot loader code. The system partition is the partition that holds the operating system files. This might be the same as the active partition, but can be different. A primary partition is a partition type on a basic disk. An active partition must be a primary partition, but there can be additional non-active primary partitions on a disk. An extended partition is a partition type that is subdivided into logical drives. The extended partition cannot be the active partition.

You have a computer with an onboard LAN adapter. The LAN adapter has failed and you are unable to connect the computer to the network. What should you do?

Add a network card using a PCI slot. Explanation In this case, you should install a network adapter in a PCI slot. Your computer would then use the new network adapter instead of the one integrated on the motherboard. While installing the new card, you should disable the onboard LAN adapter to prevent it from showing in Device Manager. Replacing the motherboard is too expensive when compared to installing a new expansion card. AGP slots are used for video cards, not network cards. Clearing the CMOS settings erases the configuration information but does not fix the LAN adapter that is not functioning.

Boot into the recovery environment and run the bootrec /rebuildbcd comman

One day while trying to start your Windows 10 system, you see the following error displayed: Could not read from the selected boot disk. Check boot path and disk hardware.

Boot into the recovery environment and run the bootrec/rebuildbcd command. Explanation This error message is generated when the system cannot find the partition specified in the BCD database where the operating system files are located. For example, the database might be pointing to the C: drive for the operating system files, but that drive does not exist. To fix this problem, boot into the recovery environment and then run the bootrec/rebuildbcd command to rebuild the boot loader database with a list of valid operating system locations. You will not be able to boot into Safe Mode because the operating system files have not yet been loaded. The fixmbr and bootcfg commands were used on older versions of Windows.

Can be used to connect wireless clients to wired clients on the same network.

Six months age, you purchased a new laptop. Since then, you have noticed that the battery life has been steadily going down. When it was new, a full charge lasted about 3 hours. Now you are lucky to get 2 hours before the battery charge level drops below 5%. What should be your first step to correct this problem?

Calibrate the battery. Explanation If your battery seems to be losing the ability to hold a charge, or if the power drops shortly after starting to use it, you might need to recalibrate the battery. Over time, the power meter gets out of sync with the actual power that is left in the battery. Calibration resets the power meter so that the percentages are a more accurate reflection of the remaining charge. It is common for batteries to lose their ability to hold a charge over time. However, most batteries last between 1-3 years. You should only replace the battery after you determine that calibration will not correct the problem. You cannot replace the power meter chip in a battery; in fact, you should never disassemble a battery. Cleaning the contacts will have no effect.

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 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 options will allow you to play the games on your home system with the best gaming experience possible?

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, or the 75 Hz card, or both will limit the performance of your system to the rate of the slowest component, which will not be sufficient for the fast moving graphics in the games.

Which of the following is a valid MAC address?

C0-34-FF-15-01-8E

Which of the following is a valid MAC address?

UTP Cable Types

Cat 3, Cat 5, Cat5e, Cat6, Cat 6a

What type of cabling can be used for an Ethernet 100Base-T (100 Mbps) network?

Category 5e UTP Category 5 UTP Explanation Ethernet 100Base-T uses category 5 and 5e cabling. Cat 3 is designed for use with 10 megabit Ethernet or 16 megabit token ring. Coaxial cabling is used with 10Base2 or 10Base5 Ethernet.

You have purchased an LED monitor and connected it to the DVI-I port on your computer using a DVI-D cable. You configure the screen resolution to 1440 x 900 with 32-bit colour. The display on the screen seems to be pixilated. What should you do to correct the problem?

Change the screen resolution to the native resolution of the monitor. Explanation LED and LCD monitors have a native display resolution. You should set the resolution of the video board to the native resolution of the monitor (whatever it might be). While it might be possible to set the resolution other than the native resolution, the images on the display will be distorted or pixelated. DVI-D and DVI-I cables are compatible-- both carry digital output to the monitor. DVI-A cables are incompatible with DVI-D or DVI-I hardware because they use an analogue signal. Changing the colour depth increases the number of colours that the monitor displays.

You have purchased a 1600 x 1200 LCD monitor and connected it to the DVI-I port on your computer using a DVI-D cable. You configure the screen resolution at 1280 x 1024 with 24-bit colour. The display output seems to be fuzzy and stretched. What should you do to correct the problem?

Change the screen resolution to the native resolution of the monitor. Explanation LCD monitors have a native display resolution. The native display of this monitor is 1600 x 1200. While it might be possible to set the resolution lower than the native display, you should use the native display setting for the clearest picture. Using a DVI-D cable is the same as using a DVI-I cable-- both will give you digital output. Using a DVI-A cable (if it will work on the monitor) could result in lower quality images as you will be using an analogue signal. Increasing the colour depth increases the number of colours that the monitor displays.

Which of the following disk maintenance utilities optimizes the performance of your hard drive by verifying the file system integrity of a hard disk and fixing the errors it detects?

Check Disk Explanation Check Disk is a utility that verifies the file system integrity of a hard disk. Check Disk detects disk integrity errors and fixes them. Disk Defragmenter optimizes the performance of your hard drive by joining fragments of files that are in different locations on your hard drive into a single location. The more information that is on the drive the more time it will take to defragment the drive. Disk Cleanup helps manage disks by locating and disposing of files that can be safely removed from the disk. Disk Management is a tool for viewing, modifying, and creating partitions.

Explanation

Check Disk detects disk integrity errors and fixes them. Errors that can be checked and fixed by Check Disk include: Lost clusters are a series of used clusters on the hard disk drive that are not associated with a specific file. A cross-linked file occurs when two files claim the same cluster. Check Disk will identify cross-linked files and correct their cluster associations. Orphaned files are files that exist on the hard drive but which are not associated with a directory in the index. Normally Check Disk can re-associate the file with the correct directory. A bad sector is a portion of the hard disk that cannot be used. Bad sectors are marked so that they are no longer used. Any used bad sectors are redirected to another sector.

A customer complains that a recently purchased monitor no longer displays a picture. You verify that the monitor is powered on and that the video cable is securely fastened to the video port. Which of the following actions should you take next?

Check the monitor's brightness and contrast settings using the controls on the monitor. Explanation It's not uncommon for a monitor's brightness or contrast controls to be accidentally turned down. Check the brightness and contrast on the monitor to see if it has any effect on the problem. When troubleshooting, be sure to check the obvious things first before taking more serious actions, such as returning the monitor to the manufacturer. Moving the video card or reloading the video driver is unlikely to resolve the customer's problem in this scenario.

Compact Disc (CD)

Explanation

Compact Discs (CDs) were first developed store digital music. Later, the CD technology was adapted to store digital computer data. Data is stored on a CD's disc surface in a series of lands and pits. Reflective light is used to interpret the data on the disc. Digital Versatile Disc (DVD) is an optical media standard that can be used to store large amounts of different types of data ( computer, data, video, audio). Single-sided discs can hold about 4.7 GB of data. Dual-layer discs can hold up to 8.5 GB of data. A red laser causes a crystal to form which creates the reflective and non-reflective areas on the bottom of the DVD-RW disc. Blu-ray Disc (BD) was originally developed for high definition video (and expanded content on movie discs), but can also be used for data storage. Blu-ray uses a blue laser instead of the red laser used with CDs and DVDs. The blue laser light has a shorter wavelength, which allows data to be packed more tightly on the disc.

You've just purchased 10 new notebook systems for your users. You are concerned that users will leave the systems on for long periods of time, which could result in display burn-in. What should you do to prevent this from happening?

Configure a screen saver on each system. Explanation Burn-in can happen when the same image is displayed on the screen for an extended period of time. The best way to prevent this from happening is to configure a screen saver on each system. Configuring the systems to automatically power off after 5 minutes of inactivity will also prevent burn-in, but will also make them very inconvenient to use. Increasing hardware acceleration settings will not prevent burn in from occurring. Installing a software utility on each system that is designed to fix stuck pixels can be used to repair a burnt-in display, but it will not prevent it from happening in the first place.

If a notebook computer is exhibiting symptoms that seem to indicate a malfunctioning keyboard, what troubleshooting steps can you take to determine if the keyboard needs to be replaced?

Connect an external keyboard. Check for special keyboard features that could be enabled that may cause some keys to perform alternate tasks. Explanation Check to see if the user has inadvertently set a special notebook keyboard feature that alters the way certain keys work. For example, setting the NumLock feature may cause part of the keyboard to emulate 10-key functionality. IF no special features have been set, you can connect an external keyboard to see if the malfunctiong keyboard symptoms go away. If they do, the laptop keyboard needs to be replaced. None of the other troubleshooting options could be used to determine what is wrong with a notebook keyboard.

You want to implement name resolution on the Linux workstations in your company. Which protocol will you use to do this?

DNS

You want to implement name resolution on the Linux workstations in your company. Which protocol will you use to do this?

DNS Explanation You can use DNS name resolution for Linux workstations for Linux workstations (as well as for most other operating systems). NetBIOS name resolution (LMHOSTS files or WINS) is typically used on Windows-based networks. The Lmhosts file is a local text file that maps Internet Protocol (IP) addresses to NetBIOS names of remote servers with which you want to communicate over the TCP/IP protocol. A WINS server address is only needed if your have older Windows clients on multiple networks. Network Time Protocol (NTP) is a means of transmitting time signals over a computer network.

Which of the following video card connectors provides digital video output?

DVI-D HDMI Explanation High- Definition Multimedia Interface (HDMI) is a digital video and audio connector used for high-definition digital audio and video. A DVI-D (digital video-digital) connection provides digital output. A DVI-I (digital video-integrated) connection also provides digital output as it sends both a digital and an analogue signal. Most video cards have DVI-I ports that allow you to connect both digital and analogue monitors. A DVI-A (digital video-analogue) connection is used only for analogue video signals, and will be found on cables but rarely (if ever a video card itself). A composite video connection on a video card provides analogue, video-only TV output in a single channel. S-video (separate-video. V/C. or S-VHS) supply analogue, video-only TV output in two channels. An HDTV connector supplies analogue, video-only TV output in three separate channels.

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?

Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not.

You have a computer with three hard disks. A RAID 0 volume uses space on Disk 1 and Disk 2. A RAID 1 volume uses space on Disk 2 and Disk 3. Disk 2 fails. Which of the following is true?

Data on the RAID 1 volume is accessible; data on the RAID 0 volume is not. Explanation In this scenario, Disk 2 is shared between both volumes. If Disk 2 fails, the RAID 1 is still accessible because RAID 1 (mirrored) volumes can sustain a loss of a single disk. The data on the RAID 0 volume is not accessible. RAID 0 uses striping, which distributes the data evenly between multiple disks. If a single disk fails, the entire volume is lost.

Windows 10 features a storage solution called Storage Spaces. What is the name of the Storage Spaces feature that allows to allocate space for redundant information using options that include two-way mirroring, three-way mirroring, and parity?

Data resiliency Explanation Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: Simple, which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as such device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. Three-way mirror requires at least five storage devices. The data is written to three storage devices. This option provides redundancy for the data if two storage devices fail at one time. Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy that the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity requires only 50 percent more redundancy space than storage space.

Which of the following devices allows network communications to be transmitted over existing AC power lines?

Ethernet over Power Explanation An Ethernet over Power device allows for network communications to be transmitted over existing AC power lines. An Ethernet over Power device is plugged in to one AC power outlet, and a second Ethernet over Power device is connected to the same AC circuit. These devices multiplex the AC copper power lines to transmit digital network signals at a frequency higher than the AC electrical power already on the circuit.

Explanation

Ethernet uses a variety of connectivity devices, including the following: A hub provides a central connection for multiple media, segments on the same subnet. When a hub receives a signal, it is repeated out to all other ports. Hubs operate in half-duplex mode, meaning devices can either send or receive data at any given time. A switch provides a central connection for multiple media segments on the same subnet. When a switch receives a signal, it forwards that signal only to the port where the destination device is connected. Switches operate in full-duplex mode meaning devices can send and receive data at the same time because transmission paths are dedicated to only the communicating devices. A router connects two network segments that have different subnet addresses. Routers use the IP address within a packet to move packets between networks. A bridge connects two segments within the same subnet that use different media types. For example, use a bridge to connect wireless clients to wired clients on the same network.

Hard disk drive (HDD)

Explanation

Hard disk drives (HDD) are thick magnetic disks made of aluminum platters, They use read/write heads to access data stored on the platters. They have up to several TB in storage capacity and their cost per MB is cheap. Solid state drive (SSD) is a flash device with storage capacity similar to a small hard drive. They are faster than other devices. They have no moving parts and last longer than other storage devices. Optical discs use lasers to read and write information that is stored in the form of pits in their reflective coating. They are ideal for storing and playing music and video. They are portable and cheap and have a long shelf life.

Healthy

You have four volumes on a basic hard disk. You convert the disk to dynamic. After the conversion, which of the following do you expect to see as the status of the fourth volume if it is valid and has no errors?

Healthy Explanation If a basic disk gets converted to dynamic, the status of all partitions on that disk would be changed to show just Healthy. There are no Primary or Logical partitions on a dynamic disk. A basic hard disk can only have 4 primary partitions. To get around this limitation on basic disks, the fourth partition is automatically configured as an extended partition that can hold logical drives. So, the fourth partition would show a status of Healthy (Logical Drive).

You have four volumes on a basic hard disk. Which of the following do you expect to see as the status of the fourth volume if it is valid and has no errors?

Healthy (Logical Drive) A basic hard disk can only 4 primary partitions. To get around this limitation on basic disks, the fourth partition is automatically configured as an extended partition that can hold logical drives.

You're troubleshooting a malfunctioning notebook computer. Nothing appears on the LED display when the system is powered on. What is the first thing you should do?

Plug in an external monitor. Explanation If the built-in monitor isn't working, connect an external monitor to the laptop. If the display appears on an external monitor but not the built-in display, the problem could be a malfunctioning LED assembly or it could be due to the display output being redirected to the external monitor port using the Fn key. If you don't get a display on the internal or external monitor, you can assume that there is a problem with the video card. Repairing the video card typically means replacing the motherboard. You should calibrate the battery if your battery seems to be losing the ability to hold a charge or if the power drops shortly after starting to use it.

What drive configurations uses striping w/out fault tolerance?

RAID 0

Which RAID configuration level provides increased using only two disks?

RAID 0 Explanation RAID 0 (striping) uses two or more disks and provides an increase in performance but not fault tolerance. RAID 1 (mirroring) uses two disks to provide fault tolerance but not an increase in performance. RAID 5 uses a minimum of three disks and provides both fault tolerance and an increase in read performance.

Which of the following drive configurations uses striping without fault tolerance?

RAID 0 Explanation RAID 0 uses disk striping and offers no fault tolerance. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. A failure of one disk in the set means all data is lost. This is the fastest of all RAID types. RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure. RAID 1 provides fault tolerance but does not use striping. An expanded volume set is a volume that spans more than one hard drive. An expanded volume set also offers no fault tolerance, yet does not use striping.

Which of the following drive configuration uses striping with parity for fault tolerance?

RAID 5 Explanation RAID 5 also uses disk striping, but provides fault tolerance for a single disk failure. Disk striping breaks data into units and stores the units across a series of disks by reading and writing to all disks simultaneously. RAID 0 uses disk striping and offers no fault tolerance. A failure of one disk in the set means all data is lost. RAID 1 provides fault tolerance but does not use striping. A RAID 10 array nests a mirrored array within a striped array.

What is an advantage of RAID 5 over RAID 1?

RAID 5 improves performance over RAID 1

What is an advantage of RAID 5 over RAID 1?

RAID 5 improves performance over RAID 1. Explanation RAID provides both fault tolerance and improved performance RAID (mirroring) provides only fault tolerance with no performance benefit.

What is the most common disk interface used for optical drives on home and office computers?

SATA

What type of interface is most commonly used for internal hard disks in notebook systems?

SATA

Which of the following is the most common disk interface used for optical drives on home and office computers?

SATA Explanation Most modern computer systems use SATA optical drives. At one time, IDE/EIDE (ATAPI) optical drives were the most common type of optical drives implemented but this has changed. SCSI was also used at one time but has fallen out of favour for optical drives. In the early 1990's some sound cards provided a proprietary internal connector for ealy CD-ROM drives, but these are now obsolete. Likewise, parallel ports were used in the early 1990's optical drives, but these are also now obsolete.

Which interface is primarily used for internal hard drives in modern desktop PC systems?

SATA Explanation SATA is primarily used for internal hard drives in modern desktop PC systems. PATA (also called EIDE, IDE, and ATAPI) is a parallel ATA interface and was the most common interface used for hard disks and CD/DVD drives in the past, but not in modern PC systems, USB and Firewire are interface standards for connecting various external devices, including external hard drives. SCSI is commonly used for server storage, but is rarely used for hard disks in modern desktop systems.

Which generation of SATA storage devices does the following? Supports up to 6 Gbps data transfer rates. Addresses solid state drives.

SATA3 Explanation SATA3 support up to 6Gbps (600 MBps). It mainly addresses solid state drives with SATA (hard disk drives are not capable of sending data at this rate). SATA1 is the original SATA standard. It provided for 1.5 Gbps (150 MBps) data transfer.

You have purchased an LED monitor and connected it to the HDMI port on your computer using an HDMI cable, You configure the screen resolution to 1280 x 1024 with 32-bit colour. The geometry of the images displayed on the screen appear to be distorted. What should you do to correct the problem?

Set the display resolution to the native resolution of the monitor. Explanation LED and LCD monitors have a native display resolution. You should set the resolution of the video board to the native resolution of the monitor (whatever it might be). While it might be possible to set the resolution other than the native resolution, the images on the display will be distorted or pixilated. Changing connection types will not correct an incorrectly set display resolution, nor will increasing the hardware acceleration or installing an updated driver.

You have purchased an LED monitor and connected it to the HDMI port on your computer using an HDMI cable. You configure the screen resolution to 1280 x 768 with 32-bit colour. The images displayed on the screen appear to be overly large. What should you do to correct the problem?

Set the display resolution to the native resolution of the monitor. Explanation LED and LCD monitors have a native display resolution. You should set the resolution of the video board to the native resolution of the monitor (whatever it might be). In this scenario, the display resolution has been set to a resolution that is much smaller than the native resolution, causing the images on the display to appear over-sized. Changing connection types will not correct an incorrectly set display resolution, nor will increasing the hardware acceleration or installing an updated driver.

You recently upgraded a client's older workstation from Windows 7 to Windows 10. The client has called to complain that the interface is very slow. For example, after clicking on the Start button, the Start Menu slowly appears on the screen. How can you fix this problem without upgrading the hardware itself?

Set the visual effects for best performance. Explanation You need to adjust the visual effects for best performance. This will disable animation, shading, and fading effects used by Windows. Doing so reduces the load on the older hardware used in the client's systems and should increase the performance of the user interface. However, the best resolution to this problem would be to install a newer video adapter in the system. Changing the resolution setting changes the size of text and windows in relation to the screen. Changing the colour depth affects the number of colours that can be displayed at one time. Increasing the video acceleration settings increases the amount of processing done by the video card instead of the CPU.

You want to set up a Windows system to also be able to boot to Linux. To be able to dual boot, the system needs a partition on which to install Linux. You don't have an extra hard disk that can be used for the Linux partition. The existing disk has no unpartitioned space available, but it has about 300 GB of free space. Which disk management operation can you perform on the disk to use some of the free space for the Linux partition?

Shrink the primary partition Explanation You can decrease the space used by primary partitions and logical drives by shrinking them into adjacent, contiguous space on the same disk. For example, if you discover that you need an additional partition but do not have additional disk, you shrink the existing partition from the end of the volume to create new unallocated space that can then be used for a new partition.

On a Windows 10 workstation, you want to use the Storage Spaces feature to create a logical drive. Which of the following components are used to configure Storage Spaces?

Storage devices, which are physical drives such as SATA drives or external drives. Pools of storage, which are logically created from free space on storage devices. Storage spaces, which are logically defined units created from a pool of storage. Explanation Storage spaces are composed of three components: Devices are the hard disks or other types of storage from which storage pools are created. You can use a variety of devices such as SATA drives and external drives to create storage pools. Pools of storage are created from the available disk space. A pool is a logical concept composed of the free space available on the specified storage devices. Storage spaces define logical units of space created from a pool. One or more storage spaces can be created from the pool. To the Windows system and the user, storage spaces appear as disks with typical drive letters (e.g., E: drive, F: drive). Parity, thin provisioning, and data resiliency are benefits of Storage Spaces.

Explanation

Storage spaces can include data resiliency. Choosing an option that provides resiliency requires you to allocate space for redundant information. The options for storage spaces data resiliency include: Simple which does not provide redundancy. This option simply adds space from the storage pool to the storage space. When you select the Simple option, all of the data in the storage space is lost if one of the drives fails. Two-way mirror requires at least two storage devices. The data is written to two devices. Two-way mirror requires twice as much device space as the amount of storage allocated to the storage space. This option protects you from a single storage device failure. Three-way mirror requires at least five storage devices. The data is written to three storage devices. This option provides redundancy for the data if two storage devices fail at one time. Parity requires that you have at least three storage devices. This option uses parity information to reconstruct data if one of the storage devices fails. Parity uses less space for redundancy than the mirror options, but performance is not as good as the mirror options if a device failure occurs. Parity require only 50 percent more redundancy space than storage space.

Your computer currently uses a 5,400 RPM hard disk. You want to improve your computer's overall performance by optimizing your hard disk performance. Which of the following would be the most effective means for optimizing your hard disk performance?

Upgrade to a 10,000 RPM hard disk. Upgrade your hard disk interface to SATA 3. Explanation Upgrading to a 10,000 RPM hard disk and upgrading to a SATA 3 disk interface are the two most effective steps you can take to improve your computer's overall performance. The 7,200 RPM hard disk is not the fastest hard disk option. At 600 Mbps, the SATA 3 disk interface is twice as fast as the SATA 2 interface. Although hard disk drives are not capable of sending data at the full Mbps they can go faster than the SATA 2 interface allows. Implementing RAID 0 does improve hard disk performance, but it requires a minimum of two disks. Adding another hard disk while keeping your current 5,400 RPM disk would not improve your hard disk performance as much as upgrading to 10,000 RPM hard disk with a SATA 3 disk interface.

You have just finished installing Windows on a system that contains four physical hard disk. The installation process has created system volume and a C: volume on the first disk (Disk 0).

Unallocated Explanation A disk that has been initialized will show as Unallocated if no volumes have been created. The Healthy or Online status indicates that the disk is turned on and can be accessed. The volume on the disk is valid and has no errors. The Formatting status is shown for volumes during the formatting process. After formatting, the status for the volume changes to Healthy. The Initializing process shows while a disk is being converted from a basic disk to a dynamic disk. After the conversion, the status for the volume changes to Healthy. The Unavailable status indicates that errors have occurred on physical or dynamic disks. The Unreadable status indicates a hardware failure, I/O errors, or other corruption but might also be caused by a delay in reading the disk in Disk Management.

A user installs a new graphics application on her Windows system. During the installation process, the application prompts the user to load a custom video driver that has been optimized for the application. She does so and then completes the installation. Several days later, the user reports that her display doesn't seem to be working properly under some conditions. To fix the problem, you need to reload the old video driver. How could you accomplish this?

Use Device Manager to roll back the video driver. Revert the system to a restore point prior to installing video driver. Explanation To roll back to a previous driver, access Device Manager and then use the Roll Back Driver option available in the video driver's properties. You may need to boot the system into Safe Mode first if the problem is serious enough to make the display difficult to see. Alternatively, you could also revert the system to a prior restore point that was created before the problematic driver was installed. You should not disable the driver in this situation. The Last Known Good configuration boot option is only available on Windows 7 and earlier systems. Even if it were available, it would not work in this scenario because the system has been rebooted and the user has logged in since the change was made. Running a startup repair would not correct a problem with an erratic video driver.

A user in sales cannot get his laptop to display through a projector. He sees the screen output on the built-in display, but the video is not being seen on the projector. What should you do first?

Use the Fn key to redirect display to the external video port. Explanation Toggle the display setting with the Fn key. Most laptops offer several display choices, such as: PC screen only, Second screen only, Duplicate (both screen), and Extend (both screens). The most likely culprit in this scenario is that the display has been toggled to PC screen only, so choosing either of the other two settings should allow the user to see the display on the projector. Upgrading the video card, replacing the display, or checking the backlight settings are not necessary as the video shows properly on the internal display.

A user recently used her notebook to make a presentation that required her to display her screen from a projector in the conference room. She is now back at her desk, her notebook is still on, but the display is blank. What should you do first to restore the display>

Use the Fn keys to toggle the display output to the laptop monitor. Explanation The first step to try to restore the display is to use the Fn keys to toggle the display output to the laptop monitor. It is very likely that the Fn keys were used to toggle the display output to the projector for the presentation and then not toggled back to the laptop monitor. Rebooting the computer will probably restore the default display output, but is not the best first solution to try. The other steps might become necessary is some cases, but only after the easiest and likeliest solutions are tried.

How do switches and bridges learn where devices are located on a network?

When a frame enters a port, the source MAC address is copied from the frame header

How do switches and bridges learn where devices are located on a network?

When a frame enters a port, the source MAC address is copied from the frame header. Explanation Bridges and switches learn addresses by copying the MAC address of the source device and placing it into the MAC address table.
