You should be very good in using the Power Options dialog box, and you should know all the options available.

Objective 3.3 Questions

You are a DST for a large insurance firm that has more than 200 users running Windows XP Professional workstations. A sales manager calls and says she was working on several important documents and a Microsoft PowerPoint presentation, and that she was interrupted by an important telephone call. During the telephone call, her workstation went into Standby mode, and then she accidentally kicked the power cord from her workstation. She told you that she quickly plugged it back in, but that did not return to the screen where her documents were displayed after logging on, as she usually does. She wants to know why this happened. What should you tell her?
1. You should tell her that Standby mode only returns you to the state the desktop was in if she selected Enhanced Standby mode.
2. You should tell her that Standby and Hibernate settings are affected by power outages, and that in either case she will have lost her data.
3. You should tell her that Standby mode writes the desktop settings to memory and that the power outage erased everything that was stored in memory.
4. You should tell her that her system BIOS disabled Standby mode when the power was loss on her workstation.
You are a DST for a small engineering company that supports ten engineers who travel throughout the United States doing presentations. The engineers are running Windows XP Professional on their laptops and require long battery life due to the air travel time when numerous reports are written. They also attend presentations and conferences where the laptops are sitting on conference room tables for hours on end. The chief engineer is concerned that too many of the engineers are leaving their laptops on when it is not necessary and have asked the engineers to put the workstations in Standby mode when the workstations are inactive. The engineers are complaining that it is too difficult to remember when to do it, and that they do not like it when the workstation automatically goes into Standby mode when they are thinking or analyzing information on the screen and not giving input. What should you suggest to the engineers that would solve this problem? (Choose the best answer.)
1. You should suggest that the engineers select Hibernate, Standby, or Do Nothing When The Laptop Lid Is Closed.
2. You can suggest that the engineers configure the laptops to go into Standby mode when 30 minutes of inactivity occur because that would give them more than enough time to think and analyze.
3. You can suggest that the engineers purchase additional batteries.
4. You can suggest that the engineers request to plug their laptops into power outlets when in a conference room environment.
You are a DST for a small clothing franchise that has seven sales representatives who are running Windows XP Home Edition on laptops. The laptops have been configured with two partitions, C: and D:. The C: partition contains the operating system, and the D: partition contains only reports and presentations to be used by the sales representatives. Each laptop has 512 MB RAM and each partition is 2 GB. The C: partition has 400 MB available disk space, and the D: partition has 1 GB of available disk space. The sales manager wants to be able to put her laptop into Hibernate mode, due to the problems she is having with her batteries constantly having to be recharged. She calls you and wants to know why she is not able to use Hibernate mode. What should you tell her?
1. You should tell her that Hibernate mode is not available on Windows XP Home Edition.
2. You should tell her that she needs more RAM.
3. You should tell her to copy the hibernate.dll file to the D: partition.
4. You should tell her that Hibernate mode requires an amount of free disk space on her boot partition (C:) equivalent to the amount of RAM (512 MB) on her workstation.
You are a DST for a large grocery store chain that supports more than 400 Windows XP Professional workstations. The owner of the company says that her utility bill has exceeded her budget allocation, and that she has heard that the workstations can be configured to shut off the monitors when there is inactivity for a specified time limit. She does not want the computers to go into Standby or Hibernate mode because she had received too many complaints from users who said it confused them. She wants to know if there is a way that just the monitors could be turned off. What should you tell her?
1. You should tell the owner that she will have to select Hibernate or Standby mode.
2. You should tell the owner that she can use the Power Options Properties dialog box to turn off only the monitor after a certain time limit of inactivity.
3. You should tell the owner that she could use the System Properties hardware option to turn off the monitor.
4. You should tell the owner that she could use Device Manager to turn off the monitor after a predetermined time of inactivity.
You are a DST for a large retail company that supports more than 800 users. To reduce utility costs, a manager asks you if it is possible to control the power consumption behavior of the workstations. What do you tell her?

Objective 3.3 Answers

Correct Answers: C
1. Incorrect: There is no such mode. Standby mode did not return her to the original state of her workstation because of the loss of power. Standby mode stores desktop information in memory, not on the hard drive like Hibernate mode does.
2. Incorrect: Standby mode does not save desktop settings to the disk like Hibernate mode does. When Hibernate is selected, everything that is stored in memory is copied to the hard drive, so data can be saved in the event of a power outage. Because everything in memory is written to hard disk, you must have a minimum of hard disk space equal to the amount of your system memory.
3. Correct: Standby mode does not save desktop settings to the disk like Hibernate mode does. When Hibernate is selected, everything that is stored in memory is copied to the hard drive, so data can be saved in the event of a power outage. Because everything in memory is written to hard disk, you must have a minimum of hard disk space equal to the amount of your system memory.
4. Incorrect: Standby mode does not save desktop settings to the disk like Hibernate mode does. When hibernate is selected, everything that is stored in memory is copied to the hard drive, so data can be saved in the event of a power outage. Because everything in memory is written to hard disk, you must have a minimum of hard disk space equal to the amount of your system memory. The system BIOS does not get erased during power losses because it is stored on a ROM (read-only memory) chip that does not rely on power.
Correct Answers: A
1. Correct: Using the Power Options Properties Advanced tab, you can select Hibernate, Standby, or Do Nothing When The Laptop Lid Is Closed.
2. Incorrect: Because the engineers have stated that they did not want the system to automatically go into Standby mode, this is not a good choice. Instead, they can use the Power Options Properties Advanced tab to select Hibernate, Standby, or Do Nothing When The Laptop Lid Is Closed.
3. Incorrect: Purchasing additional batteries might still not solve the problem because the computers might be left on constantly. A better solution is to use the Power Options Properties Advanced tab to select Hibernate, Standby, or Do Nothing When The Laptop Lid Is Closed.
4. Incorrect: In many instances, availability of power outlets might be limited. Because the chief has requested a way to place the workstations in Standby mode, a better solution is to use the Power Options Properties Advanced tab to select Hibernate, Standby, or Do Nothing When The Laptop Lid Is Closed.
Correct Answers: D
1. Incorrect: Hibernate mode is available in both Windows XP Professional and Windows XP Home Edition, but it requires an amount of free disk space on the boot partition, in this case, C: (where Windows XP Home Edition is installed), equivalent to the amount of RAM on the workstation (512 MB). Because the workstation has 512 MB RAM, and the boot partition only has 400 MB available disk space, Hibernate mode cannot be configured.
2. Incorrect: When Hibernate mode is selected, it copies the desktop settings from RAM to the boot partition, so it requires an amount of free disk space on the boot partition equivalent to the amount of RAM on the workstation.
3. Incorrect: There is no such file. For Hibernate mode to work, it requires an amount of free disk space on the boot partition equivalent to the amount of RAM on the workstation.
4. Correct: When Hibernate mode is selected, it copies the desktop settings from RAM to the boot partition, so it requires an amount of free disk space on the boot partition equivalent to the amount of RAM on the workstation. Because the workstation has 512 MB RAM, and the boot partition only has 400 MB available disk space, Hibernate mode cannot be configured.
