When Planning OceanStore Unified Storage Array Synchronization Remote Replication, the Following

question 75

Multiple Choice

When planning OceanStore Unified Storage Array synchronization remote replication, the following description is correct.  (Multiple choice.)

• A) In the scenario where the actual RPO indicator requires zero, you can choose to synchronize remote replication.
• B) Synchronous remote replication can be used to map the main and secondary storage of the two sets of LUN mapping to the host to create a scenario volume instead of….
• C) Synchronous remote replication on the remote disaster recovery can be well done.
• D) Because synchronous remote replication does not use snapshots, after synchronous remote replication is interrupted abnormally, the data on the primary LUN needs to be resumed in reply. Start synchronization to the slave site.

Standard Deviation

Standard Deviation is a measure of the amount of variation or dispersion of a set of values, indicating how spread out the data points are from the mean.

P-chart

A type of control chart used in statistical process control to monitor the proportion of defective items in a process and identify variations.

Constant Sample Size
