1. You want to calculate resource requirements for Hitachi Universal Replicator.
Which two formulas are appropriate? (Choose two.)
A) Bandwidth = peak rolling average in MB/sec
B) Host delay = 2 * [(distance between MCU and RCU) / (speed of light)] + losses due to network overhead
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)
2. What are two concerns when deploying data collectors for sizing replication? (Choose two.)
A) read MB/sec data is not collected
B) read IOPS data is not collected
C) relevant volumes not included in data collection
D) improper duration of data collection
3. A customer plans a 2-day disaster recovery test once a quarter. They use a 4-copy model for replication and have an RPO of 24 hours.
Which statement is true?
A) Creating an additional point-in-time copy is required for non-disruptive disaster recovery testing.
B) Testing against the recovery copy will not impact the RPO if they have a disaster during the test.
C) No additional point-in-time copy is required for non-disruptive disaster recovery testing.
D) Testing against the disaster recovery site point-in-time copy will not impact the RPO if they have a disaster during the test.
4. Your customer wants to ensure that the Hitachi Universal Replicator pairs are immediately suspended if the VSP detects a blocked path condition.
