技術者は、Windows と Linux の両方からデュアル ブートするようにコンピューターをセットアップしようとしています。技術者は、OS をロードする前に、コンピュータが OS イメージのあるフラッシュ ドライブにアクセスできない設定があると考えています。技術者が確認すべき設定は次のうちどれですか?
正解:B
The Unified Extensible Firmware Interface (UEFI) is the setting that should be checked when a computer is not booting from a flash drive containing an OS image. UEFI is a modern firmware that replaces the traditional BIOS and includes a "Secure Boot" feature that can prevent unauthorized operating systems from loading during the system's boot process. This security feature might be the reason the computer cannot access the flash drive before loading the OS. Disabling Secure Boot or adjusting the boot order within the UEFI settings can allow the system to boot from the flash drive. This is supported by the CompTIA A+ Core 1 (220-1101) Exam Objectives, particularly in sections 1.4 "Given a scenario set up and configure accessories and ports of mobile devices" and 4.0 "Virtualization and Cloud Computing", emphasizing the importance of UEFI settings in boot processes and virtualization .
