Hitachi Vantara Certified Expert - Replication Solutions Architect 認定 HCE-3710 試験問題：

1. A customer wants to replicate 20 TB of data asynchronously on a VSP. They have two different applications and would like to control failover of the applications independent of each other.
How much additional cache is required to support replication for the RCU?
Response:

A) 14 GB
B) 0 GB
C) 5 GB
D) 7 GB

2. A customer is using Hitachi Universal Replicator to continuously replicate a database's data and log volumes. Which two statements describe what will happen?
(Choose two.)
Response:

A) In the case of a planned outage, log volumes may not include all transactions.
B) At recovery time, the database will reconcile logs and transactions.
C) In the case of an unplanned outage, log volumes may not include all transactions.
D) A database checkpoint will be created upon failover.

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

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

4. 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?
Response:

A) a Hitachi Universal Replicator cascade off of a ShadowImage copy
B) a three data center multi-target
C) a three data center cascade solution
D) a TrueCopy cascade off of a ShadowImage copy

5. What are two concerns when deploying data collectors for sizing replication?
(Choose two.)
Response:

A) read IOPS data is not collected
B) read MB/sec data is not collected
C) improper duration of data collection
D) relevant volumes not included in data collection
