質問 1：
What are two benefits of using ShadowImage on an HUS 150?
(Choose two.)
Response:
A. S-Vol size can be larger than the P-Vol.
B. S-Vol can be cascaded off a TrueCopy volume
C. It provides up to 8 copies.
D. It provides up to 9 copies.
正解：B,C

質問 2：
A customer is planning to replicate 10 TB of data using synchronous replication. What are two primary considerations?
(Choose two.)
Response:
A. the number of host write IOPS per second of the secondary system
B. the number of host channels attached to the secondary system
C. the available bandwidth
D. the distance between data center
正解：C,D

質問 3：
A customer is conducting a test and has performed a planned failover to their Hitachi Universal Replicator copies at the secondary site. They have confirmed their recovery capabilities and they are ready to return operations to the production site.
Which fallback procedure applies?
Response:
A. Replication pairs must be suspended to allow changed tracks to be managed using the bitmap.
B. Replication direction can be reversed without need for a full initial copy.
C. A full initial copy will be required from the recovery storage back to the primary storage.
D. Copy pace should be reduced until the resync copy is complete.
正解：B

質問 4：
A customer would like a daily point-in-time copy of their database and retain each copy for two weeks.
The customer would like to maximize their host write performance on the production server when the pairs are suspended.
Which product would satisfy the requirement?
Response:
A. Copy-on-Write
B. ShadowImage
C. Hitachi Thin Image
D. Hitachi Dynamic Replicator
正解：C

質問 5：
A customer is using ShadowImage(SI) on a Virtual Storage Platform (VSP) for a point-in-time copy. The SI P-Vol resides in a SAS HDP pool and the SI S-Vol resides in a SATA HDP pool. During resychronization, the VSP cache write pending hits 60 percent utilization in CLPRO.
What are two ways to reduce the resynchronization impact on host performance?
(Choose two.)
Response:
A. Run an SI quick split.
B. Run an SI resync during non-peak hours.
C. Keep the SI pairs in PAIR state.
D. Put the SI S-Vols in a separate CLPR.
正解：B,D

質問 6：
The customer's administrator estimates that the time required to bring up the network is one hour; the time required to bring up recovery hosts will be two hours; and that the time required to failover storage and present to hosts is thirty minutes.
The recovery process must be done in sequence. The customer has a Recovery Time Objective (RTO) of three hours.
What is the difference between the RTO and the estimated time to recover?
Response:
A. The customer will be over their RTO by one hour.
B. The customer will be under their RTO by one hour.
C. The customer will be under their RTO by thirty minutes.
D. The customer will be over their RTO by thirty minutes.
正解：D
