CompTIA Linux+ (XK0-004) — Question 28

Which of the following can be used to boot a DVD from a remote device to initialize a Linux system setup on bare metal hardware as if it is a local DVD?

Answer options

• A. UEFI
• B. PXE
• C. NFS
• D. GRUB

Correct answer: B

Explanation

The correct answer is B, PXE, which stands for Preboot Execution Environment and allows for network-based booting of systems. UEFI (A) is a firmware interface for booting but does not directly handle remote DVD booting. NFS (C) is a file system protocol for accessing files over a network, and GRUB (D) is a bootloader that does not facilitate remote booting of DVDs.
