   A hospital runs an electronic health record (EHR) system across multiple PowerMax devices. The application issues writes to several devices in a specific order, and the hospital requires that the remote copy be crash-consistent. The SRDF links are asynchronous. What must the architect configure to ensure write-order consistency across all devices?

   • APlace all devices in a single SRDF consistency group
   • BConfigure each device with its own SRDF pair and rely on the application to reorder writes
   • CUse synchronous mode for each device individually
   • DEnable SRDF adaptive copy disk mode on all devices

   A retail company replicates its order database from a primary PowerMax to a secondary site using SRDF. The link between sites is occasionally congested, and the application can tolerate a few seconds of data loss. The company wants to minimize the impact of link congestion on application performance. Which SRDF mode should be used?

   • AAdaptive copy tape mode
   • BAsynchronous mode
   • CAdaptive copy disk mode
   • DSynchronous mode

   A company runs a critical application on PowerMax and replicates to a DR site using SRDF. The application requires zero RPO, but the link between sites has a latency of 10 ms. The application team complains about performance degradation. The architect is asked to balance the zero RPO requirement with application performance. Which approach should the architect recommend?

   • AMove the DR site closer to the primary site
   • BSwitch to asynchronous mode to improve performance
   • CUse adaptive copy disk mode to balance performance and RPO
   • DKeep synchronous mode but optimize the SRDF link and use PowerMax features to reduce latency impact

   A media company uses PowerMax at its primary data center to replicate a single production volume to two different remote sites for disaster recovery and for a separate reporting workload. The company wants to maintain independent RPOs for each remote site. Which SRDF topology should be used?

   • AMany-to-one (fan-in)
   • BOne-to-many (fan-out)
   • COne-to-one
   • DMulti-hop (cascade)
