Question: 1
|
A customer is preparing to migrate data between their
data centers. They need to perform deduplicalion at the data creation point and
eliminate the need for specialized deduplication hardware in their data
centers. How does HP StoreOnce Catalyst enable the customer to achieve this
goal?
A. by performing source-side deduplication
B. by performing switch-side deduplication
C. by performing server-side deduplication
D. by performing target-side deduplication
|
Answer: A
|
Explanation: By
enabling source-side deduplication (Dedupe 2.0), HP has the advantage of
performing deduplication at the data creation point. Source-side deduplication
eliminates the need for specialist deduplication hardware at remote and branch
office sites. StoreOnce Catalyst allows customers to align backup with data
protection needs, such as minimizing bandwidth utilization when moving data
between sites or data centers. Reference: Dedupe 2.0: What HP Has In

Question: 2
|
A customer is planning to migrate a database to a new
site. They need to create an extended SAN in a single fabric namespace by using
a dedicated link over a distance of 200 km. Which network protocol should they
use to achieve this goal?
A. FCIP
B. iFC
C. FCoE
D. iSCSI
|
Answer: A
|
Explanation: FCIP connects Fibre Channel fabrics over
IP-based networks to form a unified SAN in a single fabric. FCIP relies on
IP-based network services to provide connectivity between fabrics over LANs,
MANs, or WANs. Note: HP SAN extension technologies include: * FCIP (greater than 10 km to 20,000 km)
* FC-ATM * FC-SONET * WDM (greater than 35 km to 100–500
km) * Fibre Channel using long-wave transceivers (10 km–35 km)
|
Question: 3
|
customer is extending a SAN by using wavelength division
multiplexing (WDM) to migrate their master database to a new data center. They
need to ensure that there is adequate line speed to perform the migration in
the event of a primary path failure. What should the customer do to achieve
this goal? A. Ensure that all SAN
devices use the same Fibre Channel speed. B. Ensure that all SAN switches have
the same core PID number. C. Ensure that there are separate WDM paths for
transmitting and receiving packets D. Ensure that a secondary path with
sufficient buffer-to-buffer credits is available
|
Answer: D
|
Explanation: WDM devices extend the distance between two
FICON directors. The devices are transparent to the directors and do not count
as an additional hop. To accommodate WDM devices, you must have enough Fibre
Channel BB_credits to maintain line-speed performance. WDM supports Fibre
Channel speeds of 10 Gb/s, 8 Gb/s, 4 Gb/s, 2 Gb/s, and 1 Gb/s. When planning
for SAN extension, BB_credits are an important consideration in WDM network
configurations. Typical WDM implementations for storage replication include a
primary and secondary path. You must have enough BB_credits to cover the
distances for both the primary path and secondary path so that performance is
not affected if the primary path fails. Reference: HP Mainframe Connectivity

A customer plans to migrate data from a third-party
storage system to an HP 3PAR solution. The customer has leased data center
space. Which HP 3PAR Storage solution must be integrated into an HP 3PAR
rack?
A. HP 3PAR StoreServ 10800
B. HP 3PAR StoreServ 10400
C. HP 3PAR StoreServ F200
D. HP 3PAR StoreServ 7400
|
Answer: D
|
Explanation: Note:
* The HP MPX200 Multiprotocol Router provides support for HP 3PAR
StoreServ 7000 and 10000 as well as 3PAR F/T, including 1GbE iSCSI and 10GbE
iSCSI and FCoE target support. MPX200 iSCSI provides an alternative option for
HP 3PAR storage systems if you don't want to dedicate native iSCSI ports on
your array. The MPX200 also facilitates the sharing of iSCSI/FCoE connectivity
simultaneously for HP 3PAR storage systems from the same MPX200. For Data
Migration the MPX200 provides high performance migration from P6000/EVA to HP
3PAR storage systems and simplifies Data Migration from third party storage
such as IBM and EMC to HP 3PAR.The MPX200 is an ideal solution enabler for HP
3PAR customers.

Question: 5
|
A company needs to migrate from a third-party storage
system to an environment that can grow by scaling out. The solution must also
allow use of a server for downloading upgrades. Which solution meets the
company's requirements?
A. HP 3PAR StoreServ 7000
B. HP StoreOnce 6200
C. HP StoreVirtual 4000
D. HP 3PAR StoreServ 10000
|
Answer: A
|
Explanation: Note:
* HP MPX200 Multi-protocol and Heterogeneous Data Migration The HP
MPX200 Multiprotocol Router provides support for HP 3PAR StoreServ 7000 and
10000 as well as 3PAR F/T, including 1GbE iSCSI and 10GbE iSCSI and FCoE target
support. MPX200 iSCSI provides an alternative option for HP 3PAR storage

Question: 6
|
A storage administrator needs to perform a gradual
migration of large backup volumes and jobs to a remote D2D system over time.
Because this data is being replicated for the first time, the administrator
needs to populate the target device with all the relevant hash codes. Which
method should the administrator use to achieve this goal?
A. using co-location
B. using removable media
C. seeding data over the WAN link
D. setting initializer to migration
|
Answer: C
|
Explanation: * prior to being able to replicate only
unique data between source and target D2D, we must first ensure that each site
has the same hash codes or “bulk data” loaded on it – this can be thought of as
the reference data against which future backups are compared to see if the hash
codes exist already on either source or target. The process of getting the same
bulk data or reference data loaded on the D2D source and D2D target is known as
“seeding”. * Seeding is generally is a one-time operation which must take place
before steady-state, low bandwidth replication can commence. Seeding can take
place in a number of ways: / Over the
WAN link – although this can take some time for large volumes of data / Using co-location where two devices are
physically in the same location and can use a GbE replication link for seeding.
After seeding is complete, one unit is physically shipped to its permanent
destination. / Using a form of removable
media (physical tape or portable USB disks) to “ship data” between sites.

Question: 7
|
A small-business customer needs to implement a high IOPS
storage system for an application that uses approximately 7 TB of space.
Because the customer does not expect a large amount of data growth in the next
few years, they need to minimize costs. Which storage system should the
customer implement?
A. HP 3PAR StoreServ 7400
B. HP 3PAR StoreServ 10000
C. HP 3PAR StoreServ F200
D. HP 3PAR StoreServ 7200
|
Answer: C
|
Explanation: HP 3PAR F200 9.6TB capacity Incorrect: Not A: 432 TB RAW Not B: 2.2 TB capacity Not
D: 250 TB RAW
|
Question: 8
|
A customer wants a new HP 3PAR StoreServ 7200 Storage
System to maximize storage performance. What should the customer
implement?
A. quad controllers
B. Adaptive Optimization
C. 120 SSDs
D. Dynamic Optimization
|
Answer: B
|
Explanation: The HP 3PAR Adaptive Optimization (AO)
software takes optimization a step further into sub-LUN tiering. AO migrates
sub-LUN data across CPGs based on user-defined policies. Two or three CPG tiers
can be specified per policy; all volumes inside a CPG are subject of an AO
policy. AO policies usually operate on an FC and NL tier or on an SSD, FC, and
NL tier. This tool can improve system response and reduce disk acquisition cost
by storing frequently accessed data in
the faster tier while moving infrequently accessed data to the slower and
cheaper slower tier. Incorrect: Not D:
Related to online migration: P 3PAR’s Dynamic Optimization (DO) software offers
the functionality of EVA’s Dynamic LUN Migration: volumes are migrated online
to another CPG with a different RAID level, set size, drive media type ,
etc.
