A customer plans migrate several Exchange 2010 databases to a new RAID 5 storage pool on an EMC VNX. The VNX has the FAST Cache and FAST VP enablers installed.
Exchange 2010 is installed on a vSphere guest.
What performance best practice should be considered when migrating Exchange 2010 to the storage pool?

• A.Enable FAST VP for the storage pool.
• B.Use thick LUNs in the storage pool.
• C.Use eager zeroed thin LUNs in the storage pool.
• D.Enable FAST cache for the storage pool.

A corporation has configured highly available CIFS file systems with VDMs. Replication is configured from a primary site to a secondary site. During testing, the VDM and user file systems switchover successfully, but 30 minutes later Windows clients still cannot access their shares. What is the most likely cause of this problem?

• A.Source side file systems are not correctly sized.
• B.Source side VDM Replication licensing is not enabled.
• C.The CIFS service is not running on the secondary site.
• D.VDMs are not configured on the secondary site.

Refer to the exhibit.

During an initial synchronization of a MirrorView/A mirror, the Primary Image data blocks A, B, C, and D are all transferred to the Secondary Image. Before data block E can be sent to the Secondary Image, data block E is updated and becomes data block E'. What information will be shown in the Tracking DeltaMap, Transfer Deltamap,and Secondary Image once the initial synchronization is complete?

• A.Tracking DeltaMap: 1 Transfer DeltaMap: 1 Secondary Image: E
• B.Tracking DeltaMap: 1 Transfer DeltaMap: 0 Secondary Image: E
• C.Tracking DeltaMap: 1 Transfer DeltaMap: 0 Secondary Image: E'
• D.Tracking DeltaMap: 1 Transfer DeltaMap: 1 Secondary Image: E'

A customer wants to implement file system replication between two EMC VNX systems. The source production file system contains data from a random workload that resides in a pool composed of SAS drives. Due to cost concerns, the destination file system and SavVol volumes will be placed on dedicated 2 TB NL-SAS drives.
What should you tell the customer about this configuration?

• A.The destination file system can be used as a source for cascaded replication with no impact to performance.
• B.Only Flash and SAS drives should be used for Replicator SavVol volumes.
• C.Replicator session performance will decrease because SavVol shares LUNs with user applications.
• D.NL-SAS is only adequate if the source file system is on NL-SAS and contains a sequential application.

A customer has recently installed ESXi 5.0 on a five host cluster attached to an EMC VNX using FCoE. EMC PowerPath/VE has been installed on all hosts in the cluster for load balancing. The customer wants to issue PowerPath commands to all the hosts from a Remote Management Server. Which server deployment will meet the customer's requirements?

• A.A Virtual Server running RHEL5U2 64-bit
• B.A Virtual Appliance running RHELU2 64-bit
• C.A Virtual Server running RHELU2 32-bit
• D.A Physical Host running Windows Server 2008
