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.

Asynchronous replication is suitable for long distances like 4,200 km because it does not require real-time data transfer, unlike synchronous replication, which is limited by latency over such distances.
