Which one of the following entails immediately transmitting copies of on-line transactions to a
remote computer facility for backup?

A.
Archival storage management (ASM)

B.
Electronic vaulting

C.
Hierarchical storage management (HSM)

D.
Data compression

Explanation:
“Electronic vaulting makes an immediate copy of a changed file or transaction and sends it to a
remote location where the original backup is stored….Another technology used for automated
backups is hierarrchial storage management (HSM). In this situation, the HSM system dynamically
manages the storage and covery of files, which are copied to storage media devices that vary in
speed and cost. The faster media hold the data that is accessed more often and the seldom-useed
files are stored on the slower devices, or near-line devices. The different storage media rang from
optical disk, magnetic disks, and tapes. Pg. 619 Shon Harris CISSP All-In-One Certification Exam Guide
