   A company is consolidating two data centers and needs to move a large number of volumes from an older PowerMax to a new PowerMax without disrupting ongoing application I/O. The migration must be reversible if issues arise. Which SRDF use case and feature combination should the architect choose?

   • AUse SRDF data migration with a one-to-one topology and perform a controlled failover
   • BUse SRDF disaster recovery with automatic failover on link loss
   • CUse SRDF workload relocation with a many-to-one topology
   • DUse SRDF asynchronous mode with a multi-hop topology

   What is the primary benefit of placing multiple SRDF devices in a consistency group?

   • AIt allows different devices to use different SRDF modes
   • BIt increases the total storage capacity available to the host
   • CIt reduces the number of SRDF links required for replication
   • DIt ensures write-order consistency across all devices in the group

   Which SRDF mode provides the lowest potential data loss (RPO) but may impact host write performance due to waiting for remote acknowledgment?

   • ABulk copy mode
   • BAsynchronous mode
   • CSynchronous mode
   • DAdaptive copy mode

   A bank runs a core banking application on PowerMax at its primary site. The bank wants to replicate data to a secondary site for disaster recovery and also to a third site for reporting. The reporting site does not require real-time data and can tolerate up to 15 minutes of lag. The disaster recovery site must have zero RPO. Which SRDF topology and mode combination should the architect choose?

   • AMulti-hop topology with synchronous mode to the reporting site and asynchronous mode to the DR site
   • BOne-to-one topology with asynchronous mode to the DR site and synchronous mode to the reporting site
   • COne-to-many topology with synchronous mode to the DR site and asynchronous mode to the reporting site
   • DMany-to-one topology with synchronous mode to both sites

   An administrator is configuring SRDF on a PowerMax array for a new application that requires synchronous replication. The application uses multiple devices that must be replicated together. What is the most efficient way to manage these devices as a single unit in PowerMax?

   • AUse SRDF/S and rely on the host to coordinate writes
   • BUse SRDF/A and configure a separate consistency group for each device
   • CCreate an SRDF consistency group and add all devices to it
   • DConfigure each device with a separate SRDF pair and manage them individually
