220-1201 Practice Question: A user wants to boot their laptop from a USB…

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Enter the UEFI setup and change the boot order permanently.

  Why it's wrong here

  Entering the UEFI setup utility to permanently alter the boot order is a functional, but inefficient, method for a one-time boot from a USB drive. This approach requires navigating through several menus to change the default boot sequence, and then necessitates re-entering the UEFI settings again later to revert the change to the original primary boot device, such as the internal hard drive. This makes it a cumbersome solution for a temporary need, as it modifies the system's persistent configuration unnecessarily.

• ✓

  Press the appropriate key to open the one-time boot menu and select the USB drive.

  Why this is correct

  Pressing the appropriate function key (commonly F12, F10, Esc, or F9, depending on the manufacturer) to access the one-time boot menu is the most efficient and recommended solution for booting from a USB drive temporarily. This menu allows the user to select a specific boot device for the current startup session without making any permanent changes to the system's UEFI/BIOS boot order settings. It provides a quick, non-disruptive way to initiate a boot from an alternative medium, such as a USB installation or recovery drive.

• ✗

  Disable Secure Boot in the UEFI settings.

  Why it's wrong here

  Disabling Secure Boot in the UEFI settings is unrelated to the process of selecting a different boot device. Secure Boot is a security feature designed to prevent unauthorized operating systems or malicious software from loading during the startup process by verifying the digital signatures of boot loaders. While it might be necessary to disable Secure Boot if the USB drive contains an unsigned or incompatible operating system, it does not influence the *order* in which bootable devices are presented or selected; its function is purely for boot integrity validation.

• ✗

  Remove all other bootable drives from the system.

  Why it's wrong here

  Physically removing all other bootable drives from the system is an extreme, impractical, and entirely unnecessary measure for booting from a USB drive. This process involves opening the laptop chassis, disconnecting internal storage devices like SSDs or HDDs, and then reassembling the system, which is time-consuming and carries a risk of damaging components. Modern UEFI/BIOS firmware provides convenient software-based boot selection options, rendering such invasive hardware manipulation completely obsolete for this task.
