What are considerations for the storage administrator in creating the DR solution?

A storage administrator is tasked with creating a DR solution for block and file storage resources. The company has multiple regional and international sites containing a mix of physical and virtual Dell EMC Unity systems.

What are considerations for the storage administrator in creating the DR solution?
A . Synchronous remote replication should be restricted to within 100 km between sites to keep latency below ms
Block storage resources can be replicated synchronously and asynchronously
B . Synchronous remote replication should be restricted to within 100 km between sites to keep latency below 10 ms
File and block storage resources can be replicated synchronously and asynchronously
C . Asynchronous replication ensures zero data loss the remote replica in disaster conditions
Block storage resources can be replicated synchronously and asynchronously
D . Asynchronous replication over long-distance does not impact latency
Asynchronous replication ensures zero data loss to the remote replica in disaster conditions

Answer: D
