Answer:
b. Synchronous replication
Explanation:
Replication of data in storage partitions or in a number redundant array of independent disk drives helps to promote redundancy, as implied, and faulty tolerance to reduce loss of data.
There are two categories of replication and they are synchronous and asynchronous replication.
Synchronous replication requires low latency network site to mirror data, while asynchronous replication mirrors data in large metropolitan area in high latency networks.
