Which formula is appropriate?
A) Bandwidth = peak write workload
B) Bandwidth = peak rolling average based on RPO
C) Bandwidth = cycle time peak rolling average
D) Bandwidth = peak rolling average * RPO / 2
4. A customer is using a multi-target Three Data Center Delta Resync configuration with A as the primary copy, B as a TrueCopy copy, and C as a Hitachi Universal Replicator copy. The customer performs a planned outage at the primary facility, fails over, and begins running production from the synchronous copy (B).
What happens when the customer is ready to resume replication?
