A company has a storage subsystem that supports a variety of replication options. They have
purchased an identical array and placed it at a secondary site 4,200 km away and want to keep
the two arrays as closely synchronized as possible.

Which solution should be chosen?

A.
Asynchronous replication is the only replication option for distances of this length.

B.
Synchronous replication is the only replication option for distances over 4,000 km.

C.
Snapshots allow for data to be quickly captured, copied, and mounted from one storage array
to another and is the ideal solution for all distances.

D.
Synchronous replication will keep the arrays in the closest sync and is ideal for short distances
such as 4,200 km.
