A _____ is functional if it is in _____.

• A. Computer system; Normal booting
• B. Operating system; Safe mode
• C. Network device; Online
• D. Application; Active

Answer: (A)

System functionality hinges on the boot state: a computer system is functional when it completes a normal boot. When the startup sequence proceeds normally, the BIOS/UEFI initializes hardware, the bootloader and OS load, and essential services start, making the computer ready for full operation and user tasks. In contrast, Safe Mode runs with limited drivers and services, so it isn’t the standard fully functional state. Being online just means network connectivity is available, not that the entire system is functioning normally. An application being active shows that that particular program runs, but it doesn’t guarantee the whole system is ready for general use.
