Larry needs to identify a technology that provides synchronous writing that typically achieves a Recovery Point Objective (RPO) of zero lost data and not asynchronous replication. Which of the following technologies can meet this need?
A.
Mirroring
B.
Hierarchical storage management
C.
Redundant array of independent tapes
D.
Massive array of inactive disks
Explanation:
Mirroring is typically only synchronous. Synchronous writing typically
achieves a Recovery Point Objective (RPO) of zero lost data. Asynchronous
replication can achieve an RPO of just a few seconds while the remaining
methodologies provide an RPO of a few minutes to perhaps several hours.
