Which statement correctly identifies the default startup mode?

• A. Power-saving mode
• B. Normal mode
• C. Eco mode
• D. Fast mode

Answer: (D)

The default startup mode is the option that gets the system up and usable as quickly as possible right after power-on. Fast mode is designed to boot the device quickly by prioritizing speed during initialization and loading essential services first, so you can start using it sooner. This makes it the best fit as the default, since the common expectation is a responsive experience immediately after turning on the device. The other modes emphasize conserving resources or balancing performance and energy: power-saving slows the boot to save energy, Eco mode focuses more on reducing resource use, and Normal mode aims for a middle ground.
