Linux サーバーが最近更新されました。サーバーは起動プロセス中に停止し、画面が空白になり、 fs> プロンプトが表示されます。この問題の原因として最も可能性が高いのは次のどれですか。
正解:B
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide References:The fs> prompt typically indicates that the Unified Extensible Firmware Interface (UEFI) has entered the EFI shell due to a failure in locating the bootloader or a critical Linux boot file. This often occurs after an update where boot files are moved, renamed, or deleted. To resolve: * Verify the bootloader configuration (e.g., GRUB) and ensure the correct partition is set for booting. * Recreate or repair the bootloader files if necessary. * Ensure the boot sequence in UEFI settings points to the correct disk and partition. Other options: * A. USB flash drive booting:Unlikely unless the boot order was unintentionally altered. * C. BIOS not finding a bootable hard disk:Would generally result in a different error message. * D. BIOS firmware upgrade:Not typically required for this specific issue.
