D)RAN

Question

Quizplus · Accepted Answer

RAID (redundant array of independent disks) is a technology that duplicates data across multiple physical disks to improve data reliability and prevent data loss in case of disk failure. It provides fault tolerance and increased storage capacity while increasing system performance. RAS (reliability, availability, and serviceability) is a measure of system uptime and availability, but it does not refer specifically to data duplication. NAS (network-attached storage) is a type of storage device that provides file-level data access to multiple clients over a network, but it does not necessarily duplicate data for reliability. RAN (radio access network) is a telecommunications network that provides wireless connectivity to mobile devices and does not relate to data duplication.
