Maker Code 3/9 in C# Lesson 3 Review

1. You have finished configuring a new display driver and are prompted to restart the computer for the changes to take effect. Shortly after logging on, the computer screen goes blank, making working on the computer impossible. Which troubleshooting techniques or tools will allow you to recover most easily from the problem with the display driver a. Last Known Good Configuration b. Driver Rollback c. Safe mode d. Recovery Console

The correct answers are b and c. The Last Known Good Configuration option is useless because you have logged on to the computer, so the Last Known Good registry key includes the changes. Safe mode will allow you to start the system with limited drivers and services and roll back the driver using Device Manager.

2. In Device Manager, a device displays an error icon. In the General tab of the device s Properties, you notice that the Device Status is Device Could Not Start. What course of action will solve the problem

3. The vendor for a wireless network card installed in your computer has released a new driver. You want to test the driver for proper functionality. Which Device Manager option should you select to test the new driver

The Device Manager option you should select is Update Driver. Although the Reinstall Driver option would allow you to install the new driver, selecting the Update Driver option will create a backup of the current driver, enabling driver rollback if the driver does not perform properly.

If there s one truism about information technology, it s that no matter how much storage you have today, it will be full tomorrow. You probably remember when hard drives were measured in megabytes. Many organizations are now talking terabytes. And with all that data and all those users needing all that information comes an enormous strain on the storage subsystems on your servers. Large organizations are turning to storage area networks (SANs) made up of fiberconnected, fault-tolerant arrays of disk drives. But storage that is actually attached to your servers won t disappear quite yet, so you will want to make sure that you have configured server storage to provide the optimum balance of storage capacity, performance, and fault tolerance. In this chapter, you will learn how to do just that: leverage one or more physical disks to address your storage requirements. You will learn about the storage options that Microsoft Windows Server 2003 provides, including flexible structures that make it easy to extend capacity, provide redundancy, and boost performance usually without a restart! You ll also learn to configure and recover fault-tolerant disk sets created by Windows Server 2003 s redundant array of independent disks (RAID) support. Finally, you will examine Check Disk, Disk Quotas and Disk Defragmenter, which will keep those drives working smoothly and perhaps delay the inevitable exhausting of their capacity.
