A customer is using Hitachi Universal Replicator (HUR) and does not have sufficient network bandwidth. During a peak write workload, the customer overflows their HUR journals and replication suspends in error.
What happens when the customer issues a resychronization?
A. HUR performs a differential copy.
B. HUR performs an at-time split.
C. HUR performs a no copy.
D. HUR performs an initial copy.
正解:A
質問 2:
Which sizing metric is directly affected by the peak write MB/sec measurement provided by the workload analysis?
A. cache
B. telecommunication bandwidth
C. selection of DWDM or IP-based connectivity
D. shared memory
正解:B
質問 3:
A customer is implementing TrueCopy between their primary and secondary data centers. Due to budget constraints the RCU has larger, slower disk drives than the MCU.
What is the risk associated with the design?
A. Back-end director utilization may increase
B. Journal utilization may increase
C. Host response time may increase
D. Primary volumes may suspend
正解:C
質問 4:
A customer has chosen TrueCopy for their disaster recovery replication to minimize data loss. The solution must minimize any potential host performance impact.
What are two considerations for this hardware configuration? (Choose two.)
A. Production hosts should be removed from the RCU.
B. The RCU should have the same number of replication ports as the MCU.
C. MCU and RCU disk configurations should be identical.
D. Both MCU and RCU should have additional disks added as journal volumes.
正解:B,C
質問 5:
A customer has stated several disaster recovery objectives. The acceptable data loss is 4 hours. They must have their systems operational within 7 hours of a disaster. They must also have three copies of the data at the recovery site.
What is the customer's recovery point objective?
A. 3 hours
B. 11 hours
C. 4 hours
D. 7 hours
正解:C
質問 6:
A customer is concerned with maintaining real-time recovery volumes across several hundred kilometers with minimal impact to host response time. Network infrastructure between the two facilities is subject to periodic bandwidth reductions due to surges in overall network activity. The customer is unwilling to invest in additional network capacity.
Which replication approach should you recommend for this application?
A. Mediated point-in-time replication
B. Synchronous replication
C. Journal-based asynchronous replication
D. In-system replication to virtualized storage
正解:C
質問 7:
A customer has a remote replication requirement using HUS 150 arrays between two sites 150 km apart and is using only IP connectivity for the SAN infrastructure. The customer is unwilling to purchase new SAN equipment.
What will satisfy the customer's requirement?
A. TrueCopy with i SCSI
B. TrueCopy Extended Distance with Fiber Channel
C. TrueCopy Extended Distance with iSCSI
D. TrueCopy with Fiber Channel
正解:C
