   A company uses SRDF/S for disaster recovery between two PowerMax arrays. A planned maintenance window requires the storage administrator to temporarily make the secondary site the active production site, and then later return operations to the original primary. The administrator wants to minimize downtime and avoid re-initializing the replication. Which sequence of SRDF operations should be used?

   • ASuspend replication, then resume replication
   • BFailover to the secondary, then failback to the primary
   • CFailback to the secondary, then failover to the primary
   • DSwap, then failover

   A retail company uses PowerMax for its order processing system. The system can tolerate up to 30 seconds of data loss in a disaster, but the RPO must be no more than 30 seconds. The link between the primary and DR sites has a latency of 5 ms RTT, which is acceptable for synchronous replication. However, the storage administrator is concerned about the impact of synchronous replication on production performance during peak hours. Which SRDF mode should be used to meet the RPO while minimizing performance impact?

   • ASRDF/Metro
   • BSRDF/A with a short cycle time
   • CSRDF/Star
   • DSRDF/S

   Which benefit does SRDF provide in a PowerMax environment?

   • AIt increases the storage capacity of the local array
   • BIt eliminates the need for any backup solution
   • CIt accelerates local I/O performance by caching writes
   • DIt allows data to be recovered from a remote site in the event of a disaster

   A hospital runs an electronic health records (EHR) system on PowerMax. The system spans multiple LUNs and the database writes to them in a specific order. The storage administrator is configuring SRDF/S for disaster recovery and must ensure that if a failover occurs, the secondary site has a consistent image of the database. What is the most important configuration step?

   • ASet the RPO to zero for each LUN
   • BEnable SRDF/A on each LUN individually
   • CConfigure SRDF/Metro for each LUN
   • DPlace all LUNs used by the EHR system into a single SRDF consistency group

   Why is write-order consistency important in SRDF replication?

   • ATo allow multiple hosts to write to the same device simultaneously
   • BTo improve replication performance by batching writes
   • CTo ensure the remote copy is usable for recovery without corruption
   • DTo reduce the amount of data transferred over the network
