Which of the following modes saves maximum battery power while maintaining the current state of a computing session?
Answer: A Explanation:
Hibernate mode saves maximum battery power while maintaining the current state of a computing session.
What is hibernate mode? Hide
Hibernate mode is a power savingfeature for computers. In hibernate mode, the current state of a computer is saved to the hard disk, and the computer shuts down. A user will have to power on the computer to restore the previous settings.
When a computer resumes from hibernate mode, it reads the saved settings from the disk and restores the system state as it was before it entered hibernate mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or
APM-enabled, users will have to enter hibernate mode manually. Userscannot set the computer to automatically hibernate after a certain time. With ACPI-enabled and APM- enabled computers, users are able to set hibernate mode automatically.
Answer option B is incorrect. The standby mode is a power saving feature for computers. In this mode, a computer does not shut down completely. The computer goes to low power state and, as a result, it consumes less power. When the computer resumes from the standby mode, full power is restored to its devices. During the standby mode, if the power supply is disconnected or interrupted, data might be lost.
The standby mode is available automatically on ACPI-enabled or APM-enabled computers. Users do not need to enable this mode manually.
This mode is not available in non-ACPI and non-APM based computers.
Answer option D is incorrect. Safe mode is not a power saving mode. What is Safe Mode? Hide
Safe Mode is a Windows feature used to start a computer with basic drivers, such as mouse, keyboard, etc. It bypasses blocking issues, such as system corruption, or installation of incompatible drivers or system services, enabling the Administrator to resolve such issues.
Answer option C is incorrect. There is no such power saving mode as Session. Reference: TechNet, Contents: quot;Chapter 20 – Power Managementquot;

You are using infrared devices in your network. You want to improve the quality of connections and achievebetter communication between infrared devices. What will you do to achieve this? Each correct answer represents a complete solution. Choose three.
Move the devices closer together.
Keep the devices in line of sight.
Remove any obstruction betweenthe devices.
Keep the devices in different geographic locations.
Answer: A,B,C Explanation:
To improve the quality of your connections, keep the devices in line of sight so that they point directly at each other. Also, move the devices closertogether and remove any obstruction between the devices so that the signal transmitted by the devices can reach to
the other devices.
You can also verify that no other devices are interfering with the connection, because some household devices, like TV remotes, emit infrared signal that can interfere with your connection.
