What command would Kayden most likely have executed to create a backup and restore the MBR from a Linux machine?

The dd command is commonly used in Linux for low-level copying and conversion of data, making it particularly suitable for tasks such as backing up and restoring the Master Boot Record (MBR) of a hard drive. When it comes to the MBR, dd allows for precise control over the data being copied, enabling users to specify the input file (if) and output file (of). This functionality is crucial when duplicating the MBR since it contains critical boot information about the operating system and the disk structure.

For example, to create a backup of the MBR, a command like dd if=/dev/sda of=mbr_backup.img bs=512 count=1 would be used, where "/dev/sda" is the disk containing the MBR, mbr_backup.img is the file where the MBR backup will be saved, and bs (block size) is set to 512 bytes, which is the standard size of the MBR.

This command's versatility makes it an essential tool for tasks related to disk management and recovery, distinguishing it from the other options listed. For instance, while the cp command is used for copying files and directories, it is not designed for low-level disk operations. The rs
