Hitachi HITACHI DATA SYSTEMS CERTIFIED EXPERT -REPLICATION SOLUTIONS ARCHITECT Sample Questions:
1. A customer is planning to replicate 66 TB of data using Hitachi Universal Replicator. What are three considerations for sizing the expected solution? (Choose three.)
A) number of disk drives of the primary system
B) number of RAID groups for journal disks at both sides
C) the percentage of writes for the environment
D) the number of back-end directors on the recovery system
E) total number of the IOPS for the environment
2. Which two factors are used together to calculate journal size requirements to buffer replication during network outages? (Choose two.)
A) latency
B) read/write ratio
C) peak write MB/sec
D) anticipated outage duration
3. A customer is replicating a database with a five minute RPO between two HUS 150 arrays. They have workload bursts that exceed their available bandwidth.
Which replication technology would meet this requirement?
A) Hitachi Universal Replicator
B) TrueCopy
C) Hitachi High Availability Manager
D) TrueCopy Extended Distance
4. 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) consistency groups
C) number of journal groups
D) parity groups
5. You want to calculate resource requirements for Hitachi Universal Replicator.
Which two formulas are appropriate? (Choose two.)
A) Journal Capacity = (peak rolling average write MB/sec) * RPO (minimum of 6 GB)
B) Bandwidth = peak rolling average in MB/sec
C) Host delay = 2 * [(distance between MCU and RCU) / (speed of light)] + losses due to network overhead
D) Number of RAID groups for journal volumes = (peak rolling average MB/sec based on RPO) / (total throughput per RAID group)
