A Correct answer
Explanation

Disk duplexing is a variation of disk mirroring in which each of multiple storage disks has its own SCSI controller. Disk mirroring (also known as RAID 1) is the practice of duplicating data in separate volumes on two hard disks to make storage more fault-tolerant. LAN can safeguard data by disk mirroring or disk duplexing.
