A: Device Settings
Feedback: The information and configurable settings found on the Device Settings tab are based on hardware-specific information provided by the device driver.

Q: Why are the device drivers for graphics adapters considered to be more problematic than drivers for other devices? (Choose all that apply.)
- The device driver is likely to be revised more often.
- The device driver is likely to be simple to install and without adequate documentation.
- The device driver is less likely to be included with the operating system.
- The device driver is more likely to cause compatibility or functionality problems.
A: The device driver is likely to be revised more often.; The device driver is less likely to be included with the operating system.; The device driver is more likely to cause compatibility or functionality problems.
Feedback: Many of the graphics adapters on the market are really self-contained computers in themselves, with their own processors and memory. The drivers for these complex devices are equally complex, and are often much more problematic than simple keyboard drivers for the following reasons: - The device driver is likely to be revised more often: Drivers that are required to do more are more likely to have problems. Generic keyboard drivers can go for years without upgrades, because keyboards rarely change. Manufacturers often release new graphics adapters, however, and therefore require new drivers as well. - The device driver is less likely to be included with the operating system: The Windows 8.1 installation disk includes hundreds of device drivers, but the older the operating system gets, the less likely it is to include the latest drivers for the newest devices. In these cases, you must obtain the drivers you need from the hardware manufacturer and install them yourself. - The device driver is more likely to cause compatibility or functionality problems: New devices are often rushed to market, and as a result, the drivers that ship with them might not be fully debugged. This is particularly true with graphic adapter drivers. It is a good idea to always check the manufacturer’s web site for the latest drivers before installing new hardware.

Q: Normally, why do hardware manufacturers release new driver updates? (Choose all that apply.)
- To change the startup method of the device
- To address problems with the previous driver release(s)
- To remove features not licensed from the device
- To enhance performance of the device
A: To address problems with the previous driver release(s); To enhance performance of the device
Feedback: Typically, there are three main reasons why hardware manufacturers release new driver updates: - To address problems with the previous driver release(s) - To implement new features - To enhance performance of the device

Q: What is the basic process employed to digitally sign a device driver or other piece of software?
- The device driver files are encrypted using the publisher’s public key and then run through a hash algorithm.
- The device driver files are run through a hash algorithm and then encrypted using the publisher’s private key.
- The device driver files are encrypted using the publisher’s private key and then run through a hash algorithm.
- The device driver files are run through a hash algorithm and then encrypted using the publisher’s public key.
A: The device driver files are run through a hash algorithm and then encrypted using the publisher’s private key.
Feedback: The process the publisher uses to create the digital signature starts by running the device driver files through a hash algorithm and then using the publishers private key to transform the hash result cryptographically. The resulting value is the digital signature of the device driver.

Q: What is the value of a protected checksum dependent upon?
- The size of the data object
- The contents of the data object
- The regional formatting of the data object
- The country of origin of the data object
A: The contents of the data object
Feedback: A digital signature value is a protected checksum. A protected checksum is the value of an algorithmic function that is dependent on the contents of the data object and that is stored together with the data object.

Q: Which of the following statements are true regarding the behavior of Windows 8.1 64-bit editions and drivers? (Choose all that apply.)
- If the driver is not signed, Windows will prompt you for action.
- If the driver is not signed, Windows will not install it.
- If the driver has been modified after being signed, Windows will prompt you for action.
- If the driver has been modified after being signed, Windows will not install it.
A: If the driver is not signed, Windows will not install it.; If the driver has been modified after being signed, Windows will not install it.
Feedback: As with earlier 64-bit versions of Windows, Windows 8.1 requires device drivers to be digitally signed, or it will not install them. Also, new to Windows 8.1 is a check to see if a driver has been modified. If it has, Windows 8.1 will again refuse to install it.

Q: What should you enter into the Run dialog box to open the Device Manager console?
- devcmgr.msc
- dvcmgr.msc
- compmgt.msc
- devmgmt.msc
A: devmgmt.msc
Feedback: From the Run dialog box, you will type the file name of the Device Manager snap-in (devmgmt.msc) in the Open text box, and then click OK.

Q: On which tab of a driver’s properties dialog box will you find information about the driver’s provider and date of creation?
- Details
- Resources
- General
- Events
A: Events
Feedback: The Driver tab displays the device driver’s provider, date, version, and digital signer.

Q: On which tab of a driver’s properties dialog box will you find information about any conflicts the driver may be experiencing?
- Details
- Resources
- General
- Events
A: Resources
Feedback: The Resources tab displays the hardware resources being used by the device and indicates whether there are any conflicts with other devices in the computer.

Q: After updating a device driver, the device has started to malfunction. What should you do first to try and resolve this issue?
- Disable the device
- Reboot the computer
- Uninstall the device
- Roll back the driver
A: Roll back the driver
Feedback: It is not uncommon for new drivers to cause more problems than they solve, and many users find that they would prefer to go back to the old version. Windows 8.1 makes this possible with the Roll Back feature, which you initiate by clicking the Roll Back Driver button on the Driver tab of the devices Properties sheet. This procedure uninstalls the current driver and reinstalls the previous version, returning the device to the state before you performed the most recent driver update.

Q: What is the net effect of deleting a device using Device Manager and then restarting the computer?
- The device will be removed from the system until you manually reinstall it within Windows.
- The device will be detected by Windows during the restart and Windows will try to reinstall it automatically.
- The device will be detected by Windows during the restart but Windows will not try to reinstall it since it was previously manually deleted.
- The device will be detected by Windows during the restart and you will be prompted to take an action by Windows.
A: The device will be detected by Windows during the restart and Windows will try to reinstall it automatically.
Feedback: Deleting a device and then restarting the computer will allow Windows 8.1 to detect and install the device again automatically.

Q: When Windows fails to correctly identify a detected device during the Windows installation, several things can happen. Which of these options is not one of the possible outcomes?
- The Windows installation program installs a generic driver instead.
- The Windows installation program leaves the device without a driver and completes the installation.
- The Windows installation program reboots the computer and attempts to identify the device again.
- The Windows installation program permits you to supply an alternate driver.
A: The Windows installation program reboots the computer and attempts to identify the device again.
Feedback: One of the primary functions of the Windows 8.1 installation program is to identify the hardware devices in the computer and install the appropriate device drivers for them. For most devices, this process occurs invisibly. There are occasions, however, when the installation program fails to identify a device. When this occurs, one of three things happens: - The Windows installation program installs a generic driver instead. - The Windows installation program leaves the device without a driver and completes the installation. - The Windows installation program permits you to supply an alternate driver.

Q: What does the fact that you can decrypt a driver using that signer’s public key confirm?
Feedback: That the owner of the private key has signed it and that the software has not been modified The fact that you can decrypt the driver using that signer’s public key confirms that the owner of the private key has signed it and that the software has not been modified.

Q: With a few exceptions, the device drivers included with the Windows 8.1 operating system are supplied by the ___________, not by __________.
Feedback: hardware manufacturers, Microsoft With a few exceptions, the hardware manufacturers themselves supply the device drivers included with the Windows 8.1 operating system, not Microsoft. Therefore, if you experience driver problems for a specific device, you are much more likely to get help from the hardware manufacturer than from Microsoft.

Q: As a general rule, what is considered best practice regarding driver updates?
Feedback: Test them before deploying them As a general rule, it is a good idea to test all driver updates before deploying them, especially in an enterprise environment. A comprehensive testing program will apply a new update to all the workstation environments currently in use on production networks and run them through a realistic program of everyday tasks under typical operating conditions.
