Question #: 199
Topic #: 1

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. Asynchronous replication ensures zero data loss the remote replica in disaster conditions Block storage resources can be replicated synchronously and asynchronously
C. Asynchronous replication over long-distance does not impact latency Asynchronous replication ensures zero data loss to the remote replica in disaster conditions
D. 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

A is correct. D is not correct as in last it says "File and block storage resources can be replicated synchronously and asynchronously" which is not correct statement, File can only be Async replication.

Create a synchronous replication session for file storage Before you begin Complete the following: For remote replication: Identify the remote system that will act as the replication destination. Create relevant replication interfaces, replication connection, and a storage resource on the remote system that will act as the destination. The storage resource on the destination system must have the same size. For local replication, create a storage resource that will act as the destination. For file replication, create a replication session on the NAS server associated with the file storage.

should be D. Async is not zero data loss.
