The correct answer is B. Mixed Mode Replication. The customer needs bidirectional replication between primary and DR sites, with the DR site performing data mining whose results are replicated back without impacting its performance; Mixed Mode Replication enables this solution.
Question
An existing environment contains a two-node HP 3PAR StoreServ 10400 storage array with approximately 60 TB of capacity spread across three tiers. The customer plans to replicate their business critical data to a remote DR site. The customer cannot afford to lose any of this data. You propose that the customer install an HP 3PAR StoreServ 7400 Storage system at the DR site. The CFO does not want the remote equipment to sit idle, so the customer will use that equipment for data mining. The results must be replicated back to the main site. The customer also requires that the replication of the data mining results have zero impact on the data mining performance. Which HP 3PAR technology enables the proposed solution to meet the customer requirements?

Why each option
The customer needs bidirectional replication between primary and DR sites, with the DR site performing data mining whose results are replicated back without impacting its performance; Mixed Mode Replication enables this solution.
Peer Motion is used for non-disruptive data migration between 3PAR arrays, not for continuous replication to a DR site.
Mixed Mode Replication (MMR) for HP 3PAR StoreServ arrays allows a single storage system to function concurrently as both a primary replication source for local volumes and a remote replication target for volumes from another array. This enables the DR site's 3PAR 7400 to serve as the target for critical data from the 3PAR 10400, while also acting as the source for replicating data mining results back to the primary site, satisfying the bidirectional replication requirement.
Online Import is a feature to migrate data from third-party storage systems to HP 3PAR, not for ongoing replication between 3PAR systems.
Adaptive Optimization is an auto-tiering feature within a single 3PAR array to optimize data placement across different storage tiers, not for replication between arrays.
