EMC provides free practice tests to assess your knowledge in preparation for the exam.  Practice tests allow you to become familiar with the topics and question types you will find on the proctored exam. Your results on a practice test offer one indication of how prepared you are for the proctored exam and can highlight topics on which you need to study and train further.  A passing score on the practice test does not guarantee a passing score on the certification exam.

1: A customer runs its critical Oracle environment through a Fibre Channel connection to a CX3-40c. In order to leverage the existing iSCSI connections, management decides to allocate a small amount of storage to support several Windows file servers. The customer needs to make certain that the Oracle SLA is not impacted by the non-critical Windows file servers. Which solution do you recommend?
A.Use Navisphere Quality of Service Manager to set limits on applications connected through iSCSI
B.Change the write aside cache value for Windows LUNs
C.Use Navisphere Service Taskbar to assign a higher SLA to the Oracle environment
D.CX3-40c will automatically assign higher priority to FC connections over iSCSI
Correct Answers: A

2: A customer has set up a disaster recovery site 50 miles (81 km) away from their production site. The customer is using MirrorView/S over IP with the Write Intent Log enabled. In addition, they have a dedicated 45 Mb/s line with a latency of 2 ms. During the testing of the automated solution for disaster recovery, an administrator accidentally disables the Write Intent Log. What is the likely outcome of this error if a secondary image becomes fractured?
A.The fracture log will continue to maintain a log of changed blocks.
B.The fracture log will continue to persistently maintain a log of changed blocks.
C.The Write Intent Log will flush all records of changes.
D.The Write Intent Log will hold change records up to the point where it was disabled.
Correct Answers: A

3: A customer has two 50 GB MirrorView/S mirrored LUNs between two CX3-40s without a Write Intent Log. LUN1 is on SP A and LUN2 is on SP B. The two CX3-40s are connected via dedicated Fibre Channel links.
During the nightly maintenance window, the connection between SP A on the local array and SP A on the remote array is lost for 2 minutes. SP B is unaffected. When the customer logs in the next morning, they notice that LUN1 has a status of "attention" and is still fractured.
What caused this behavior?
A.Auto recovery is not possible on the CLARiiON
B.Missing Write Intent Log
C.Recovery policy is set to Manual
D.SP A set the affected front-end FC port administratively down
Correct Answers: C

4: A customer has a 300 GB application LUN on which they would like to take a snapshot. The LUN will later be presented to a backup host for testing. The production LUN stays idle during the backup test. The testing process performed by the backup host is write intensive and will change all the data on the LUN during the test period. What is the minimum required Reserved LUN Pool size?
A.220 GB
B.420 GB
C.620 GB
D.820 GB
Correct Answers: B

5: A customer has an SQL database that initiates a clone for reporting nstance by accounting  The clone is mounted read-only on an alternate host. The production LUN is RAID 1/0 and is 750 GB in size.
The SP event logs indicate that the clone LUN was trespassed during the synchronization. What is the status of the clone?
A.Peer SP continues the operation but the clone is corrupt
B.Peer SP fractures the clone and will need manual resynchronization
C.Peer SP halts the operation and the clone is now corrupted
D.Peer SP will continue the synchronization and the clone remains usable
Correct Answers: D

6: A customer has decided to implement a DR solution using CLARiiON storage. The target storage will be located 15 miles (24 km) from the source storage, which will be connected by Fibre Channel. There is no IP connectivity to the DR site for CLARiiON management. The site will require the use of a modem for management and monitoring. Which Event Monitor architecture should be used?
Correct Answers: A

7: A company has requested an independent consultant to develop and implement a security model for the CLARiiON storage platform. The company has limited access to the administrator role by removing rights for all accounts. However, they would like to keep the single administrator role account for top level management.
Management of user security should not be done by the administrator role user. In addition, the storage object administrators should not be able to change user security when using the Secure CLI. CLARiiON storage systems are located in a protected data center with limited physical access.
Which method should be employed to manage user security?
A.Create a Security Administrator role user and create a Manager role user account for storage object managers.
B.Create a Security Administrator role user, enable the CLI filter, and create a Manager role user account for storage object managers.
C.Implement security using PKI certificates, create a Security Administrator role user, and enable the CLI filter.
D.Implement security using PKI certificates, enable the CLI filter, and create a Manager role user account for storage object managers.
Correct Answers: B

8: A customer has recently upgraded their CLARiiON to FLARE R26. What software and configuration changes must the storage administrator ensure are in place to take advantage of the Asymmetric Active/Active features of the software?
A.PowerPath 5.0; and change all initiators to use Failover mode 2
B.PowerPath 5.0; disable ArrayCommPath, and change all initiators to use Failover mode 4
C.PowerPath 5.1; and change all initiators to use Failover mode 4
D.PowerPath 5.1; disable Array CommPath, and change all host initiators to use Failover mode 3
Correct Answers: C

9: An AIX administrator requests an additional LUN for a development server. The server already has existing LUNs allocated from the CLARiiON array. The storage administrator creates the desired LUN size, masks it to the AIX host, and notifies the AIX administrator.
The AIX administrator runs cfgmgr to rescan new disks and notices the appropriate number of logical hdisks. However, the AIX administrator is unable to add the logical hdisks to the desired volume group.
What should be done to ensure the new LUN is read/write ready?
A.Execute powermt check from the host to create the emcpower#
B.Execute powermt config from the host to create the hdiskpower#
C.Execute powermt load from the host to create the emcpower#
D.Execute powermt restore from the host to create the disk slices
Correct Answers: B

10: A customer has been performing MirrorView/S replication between different buildings in their campus. An SP on the source CLARiiON failed and needed to be replaced. The failure caused the mirrors on the failed SP to perform a full resynchronization. What can the customer do to protect against full resynchronizations in the case of SP failures?
A.Add the write intent log to the consistency group
B.Enable persistence for the fracture log
C.Enable write cache for the write intent log
D.Enable write intent logging
Correct Answers: D
