You are interviewing a customer about their applications. The customer requires write order fidelity for their application.
What would you recommend?

• A.host groups
• B.parity groups
• C.consistency groups
• D.number of journal groups

Which two workload measurements are used to calculate bandwidth requirements for replication? (Choose two.)

• A.readIOPS
• B.Write MB/s
• C.Host response time
• D.Write IOPS

You are designing an asynchronous replication solution for a customer. The customer would like to replicate a database and transaction logs. The customer experienced an unplanned outage.
In this scenario, which statement is true?

• A.Log volumes will contain all transactions.
• B.The database cannot be recovered.
• C.The database can be recovered to current state.
• D.Log volumes may not contain all transactions.

A large bank requires a no data loss copy of data over 250 km away, however they have budget restrictions which prevent them from placing hosts at the in-region intermediate site and therefore will always recover at the out-of-region remote location.
Which solution meets the requirement?

• A.a TrueCopy cascade off of a ShadowImagecopy
• B.a three data center cascade solution
• C.a Hitachi Universal Replicator cascade off of a ShadowImagecopy
• D.a three data center multi-target

You want to calculate resource requirements for Hitachi Universal Replicator.
Which two formulas are appropriate? (Choose two.)

• A.Host delay = 2 * [(distance between MCU and RCU) / (speed of light)] + losses due to network overhead
• B.Bandwidth = peak rolling average in MB/sec
• C.Journal Capacity = (peak rolling average write MB/sec) * RPO (minimum of 6 GB)
• D.Number of RAID groups for journal volumes = (peak rolling average MB/sec based on RPO) / (total throughput per RAID group)
