You are also concerned about the availability of data stored on each office’s server. You would like to add technology that would enable continued access to files located on the server even if a hard drive in a server fails. What integrity control allows you to add robustness without adding additional servers?
A. Server clustering
B. Load balancing
D. Scheduled backups
Scroll down for answer
RAID uses additional hard drives to protect the server against the failure of a single device. Load balancing and server clustering do add robustness but require the addition of a server. Scheduled backups protect against data loss but do not provide immediate access to data in the event of a hard drive failure.
