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.Asynchronous replication ensures zero data loss the remote replica in disaster conditionsBlock 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 msBlock storage resources can be replicated synchronously and asynchronously
• C.Synchronous remote replication should be restricted to within 100 km between sites to keep latency below 10 msFile and block storage resources can be replicated synchronously and asynchronously
• D.Asynchronous replication over long-distance does not impact latencyAsynchronous replication ensures zero data loss to the remote replica in disaster conditions

• B.From the Pool Properties page, configure the Snapshot schedule
• C.Only manually taken snapshots are supported on existing LUNs
• D.From the LUN Properties page, configure the Snapshot schedule
