QUESTION 83
When sizing a solution involving deduplication. how does the rate of changed blocks between backups affect the deduplication ratio?
A. Deduplicaton ratio is only afiected by the backup software.
B. The lower the block change rate. the higher the deduplication ratio.
C. No changed blocks between backups result in a deduplication ratio of 0%
D. The rate of changed blocks does not affect deduplication efficiencye
Answer: B
Explanation:
Architecting Multi-site HP Storage Solutions page258 – The Lower the ‘Block Change Rate’ of the backup datathe higher the deduplication ratio.
QUESTION 84
A customer has an environment that spans two data centers in a campus environment. The primary storage is HP 3PAR 10400, and data is replicated between sites with an RPO of zero.
Recent bad weather has caused flooding near the customer site and the customer is questioning whether they have adequate protection. You suggest creating a data center at a remote location and actively replicating the data to it. The customer is concerned that the remote link to the third site will have insufficient bandwidth and will create a local replication bottleneck.
Which statement addresses the customer concerns?
A. Synchronous Long Distance will schedule data replication outside high latency periodsautonomic ally
B. Data is transmitted in a continuous stream with write order being handled by the target array.
C. Remote Copy uses multiple connections over the same link from multiple volumes.
D. Over provisioning of the remote link will ensure enough bandwidth is always available for replication.
Answer: C
Explanation:
C – Correct.

QUESTION 85
You are designing an HP 3PAR StoreServ solution that replicates to a second 3PAR StoreServ array at the customer secondary data center, which is 20 miles away You determine that the round trip latency between sites is 5ms.
Which replication solution should you recommend?
A. Synchronous Long Distance
B. Asynchronous Periodic
C. Synchronous
D. Asynchronous Real Tame
Answer: B
Explanation:
Synchronous Replication supported on round trip latencies less than 2.6. so convert to async.
QUESTION 86
A system administrator is integrating a tape library into a SAN environment to facilitate the SAN backup process. The administrator needs to simplify configuration and maintenance procedures and to manage security and reliability across the SAN.
What should the administrator do to accomplish these tasks?
A. Implement a Fibre Channel interface controller.
B. Configure the SAN for automatic zoning information updates.
C. Install DAT drives that use DDS technology and automated disaster recovery.
D. Implement an FC-AL topology by modifying an N_Port to be an NL_Port
Answer: A
Explanation:
QUESTION 87
Your customer has made a strategic decision to implement a DR solution that will incorporate an active/ active bi-directional replication configuration. The two sites in question will have live applications running at both locations, and both sites will have a fluid server estate with new systems coming online on a regular basis. Additionally, there is an aggressive server replacement schedule keeping instep with the HP server generation roadmap.
All of the customer servers will utilize Boot from SAN. The sites are 55 km apart with a single 1G Ethernet link that is at 50% utilization. There is no SLA. The customer has already purchased one pair of MPX200 FCIP gateways per site.
What is a potential effect of this configuration? (Select two.)
A. The link speed will need to be upgraded to 10Gb
B. WAN instability will cause fabric instability.
C. Multiple 1Gb links will form a single 10Gb link.
D. LSANs will maintain fabric stability.
E. The fabric will be extended across the two sites.
Answer: BE
QUESTION 88
A customer has heavy bandwidth traffic on their WAN link that they have isolated to HP 3PAR StoreServ Remote Copy replication between their primary and DR site. They are not concerned with the RTO but would like to improve the RPO.
Which recommendation should you make to decrease their WAN link traffic?
A. Use synchronous long distance mode of the entire database
B. Use synchronous mode replication of the entire database
C. Create more Remote Copy volume groups
D. Replicate Just the database logs
Answer: D
QUESTION 89
A retail customer has primary data centers, distribution centers, and retail stores. The retail locations are smaller sites that have less than 2 TB of data that need to be highly available. Each location is consolidating between six and twelve physical servers into a virtual cluster running on two HP ProLiant DL380 Gen8 servers.
The customer needs a low-cost storage solution that they can use at each retail location and can scale using similar technology for the distribution centers. The solution also needs to integrate with VMware and provide future replication with no additional cost.
Which HP Storage solution should you recommend?
A. HP Storevirtual
B. HP 3PAR StoreServ
C. HP MSA
D. HP EVA
Answer: C
Explanation:
A – correct. http://h18004.www1.hp.com/products/quickspecs/14437_div/14437_div.PDF p7 bullet 2 “Industry leading VMware integration” while bullet 1 claims “Every StoreVirtual array includes integrated synchronous and asynchronous replication at no additional cost. ”
B – too expensive for retail store
C – MSA has replication; SRA for VmWare. cost less than storevirtual. just for 2 servers – direct attach. no sense to use LeftHand for 2 servers in a remote office.
D – additional costs for replication.
QUESTION 90
A backup administrator has an HP D2D4112 G2 Backup System,which was upgraded to 3.x software and uses HP Data Protector 7.01.The administrator is ready to implement HP StoreOnce Catalyst. What should the administrator purchase so the existing infrastructure and software investment is maximized?
A. a new HP StoreOnce B6200 Backup System with HP Catalyst license
B. a new HP StoreOnce 4220 Backup System with HP Catalyst license
C. HP Catalyst license for the existing HP StoreOnce system
D. HP Data Protector Catalyst license
Answer: C
Explanation:
A and B are incorrect, because : http://www8.hp.com/h20195/v2/GetDocument.aspx?docname=4AA4- 4673ENW p9, topic “StoreOnce Enhancements for 2013”
C – correct :
http://h18004.www1.hp.com/products/quickspecs/productbulletin.html#spectype=worldwide&type=html&docid=14450
See : Features -> topic “HP StoreOnce Catalyst -seamless data movement across the enterprise” quote : “For StoreOnce Catalyst implementation with StoreOnce 2620, 4210, 4220, 4420, 4430: Each Catalyst-enabled product requires a StoreOnce Catalyst license per base unit that is to be used as a target for Catalyst backups or copy operations. ”
D – did not check, because C is correct.
