   A financial services company runs a multi-device database on PowerMax. They need to ensure that the SRDF replication maintains write-order consistency across all devices in the event of a disaster. The administrator is configuring SRDF and wants to use a consistency group. Which SRDF feature should be enabled to guarantee that all writes are applied in the same order on the R2 side?

   • ASRDF Consistency Group (CG)
   • BSRDF/Asynchronous mode
   • CSRDF Adaptive Copy
   • DSRDF/Synchronous mode

   An administrator needs to create a new SRDF pair between two PowerMax arrays. The administrator is using SYMCLI and wants to establish the pair in synchronous mode. Which SYMCLI command should be used?

   • Asymrdf -g <grp> establish -type RDF1 -rdf <rdfg> -remote_rdf <rdfg> -synch
   • Bsymrdf -g <grp> add -type RDF1 -rdf <rdfg> -remote_rdf <rdfg> -async
   • Csymcfg -g <grp> add -type RDF1 -rdf <rdfg> -remote_rdf <rdfg> -synch
   • Dsymrdf -g <grp> create -type RDF1 -rdf <rdfg> -remote_rdf <rdfg> -synch

   An administrator is performing a planned failback after a disaster recovery test. The SRDF pair is currently in the 'Failed over' state. The administrator wants to return the R1 device to the production role. Which operation should the administrator perform?

   • ASRDF Split
   • BSRDF Suspend
   • CSRDF Failback
   • DSRDF Failover

   What is the main benefit of using an SRDF consistency group for a multi-device application?

   • AIt ensures the target copy is crash-consistent across all devices, allowing a consistent recovery point.
   • BIt automatically fails over the application to the target in case of a source failure.
   • CIt allows the target devices to be used for read/write operations while replication is active.
   • DIt reduces the amount of data that needs to be replicated by compressing the writes.

   After a planned failover, what is the purpose of the failback operation?

   • ATo return production to the original source device and resume replication.
   • BTo synchronize the target with the source before the failover.
   • CTo create a new consistency group for the target devices.
   • DTo permanently keep the target as the primary and remove the SRDF pair.
