Lesson 2 Review
1. Under what circumstances would you adjust the resource settings for a device
Adjustments to a driver are usually necessary for resolution of device conflicts involving devices that cannot be completely configured automatically by the operating system, such as older Industry Standard Architecture (ISA) devices or devices bridged to Peripheral Component Interconnect (PCI).
2. You need to remove a PnP device from a configuration temporarily, but want to leave it physically connected to the computer. You want to minimize the amount of work required to use the device later. Which of the following is the best option to accomplish your goal a. From the Properties page of the device, choose Do Not Use this Device (Disable). b. From the Properties page of the device, choose Uninstall. c. Using the Safely Remove Hardware utility, choose to remove the device.
The correct answer is a. This method will allow for the temporary disabling of the device. All that needs to be done for the device to be usable again is to Enable it. Other options require either a reinstallation or rescanning of the computer to reactivate the device.

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 prob lem 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, making the last changes permanent. Safe mode will allow you to roll back the driver by using Device Manager.
2. In Device Manager, you have a device that displays an error icon. On the Properties page for the device, you read that the Device Status is: device could not start. What course of action will solve the problem
