You are planning a CIFS DR solution for two existing EMC VNX. Each VNX has dual Control Stations. Each VNX is also configured for a RecoverPoint protection solution on other VNX LUNs that are non-file related. What recommendation would you give the customer concerning the CIFS DR solution?

A. Configure IP aliasing on the Control Stations for both source and destination VNX systems before configuring VNX Replicator

B. Configure IP aliasing on the Control Stations for both source and destination VNX systems after configuring VNX Replicator

C. Configure IP aliasing on the source VNX system Control Stations before configuring VNX Replicator, and then configure IP aliasing on the destination VNX system Control Stations after configuring VNX Replicator.

D. Configure IP aliasing on the source VNX system Control Stations before configuring VNX Replicator and use RecoverPoint to provide protection of the source VNX Control Stations to the destination VNX.

A customer has vSphere v4.x hosts connected to an EMC VNX with thin provisioned pools. They report capacity shortages even after deleting or migrating some VMs. You recommend the customer upgrade their virtual environment to vSphere v5.0 to benefit from the new features and enhancements in VAAI. Which VAAI feature will address their issue?

A. Dead Space Reclamation

B. Thin Provisioning Stun

C. Hardware Acceleration

D. Hardware assisted locking

A customer has an EMC VNX configured as an FTP server. They want to determine how many FTP connections are currently open. What server_stat statistic type could be used to determine this information?

A. fact

B. set

C. counter

D. element

A storage administrator recently replaced their secondary EMC CLARiiON with a new EMC VNX. The secondary CLARiiON was used to store secondary images of their production LUNs using MirrorView/S.

After the replacement, the storage administrator realizes they fractured the mirrors to the primary CLARiiON, but did not destroy them. The storage administrator reports they are not able to destroy the old mirrors and receives an error message stating the secondary SP cannot be reached.

What is the recommended method to destroy the old mirrors?

A. Enable Engineering Mode and delete the mirrors.

B. Put the original CLARiiON DAEs into the VNX and delete the mirrors.

C. EMC Support must be engaged to delete the mirrors.

D. Use Navisphere Secure CLI to delete the mirrors.

Exchange 2010 is installed on a virtual machine using VMDK files. Replication Manager is being used to take snapshots of the virtual machine files and back them up to disk. After a few weeks, the Exchange server backups stop functioning. What is the most likely reason for this failure?

A. Replication Manager agent service has stopped

B. Replication Manager can only snapshot powered off VMs

C. Replication Manager is not compatible with VMFS version 5

D. Replication Manager agent is installed on each DAG server

An SQL server is connected to a VNX array using dual HBAs connected to separate fabric switches with no ISLs (Inter Switch Links). PowerPath is used for multipathing. What is the minimum acceptable response time threshold that will ensure server to storage response time for log file write operations is "very good"?

A. <3ms

B. <10ms

C. <12ms

D. <5ms

You are implementing a VNX using AVM, and you cannot create any more dvols from their remaining classic LUNs to create a stripe volume.

What could be a reason for this?

A. LUNs must have the same RAID configuration.

B. LUNs must come from the same RAID Groups.

C. LUNs must not exceed 18 TB in size.

D. LUNs must have different RAID configurations.

What action in RecoverPoint/SE will cause a full volume sweep?

A. Detaching the Write Splitter for a replication volume

B. Pausing replication for a Consistency Group

C. Changing the assigned primary RPA for a Consistency Group

D. Rebooting the primary RPA

When deploying a RecoverPoint/SE solution using vRPAs, which connectivity method is used by the vRPAs to access the replication volumes?

A. iSCSI

B. Fibre Channel

C. FCoE

D. FCIP

A System Administrator is configuring Data Mover interfaces. They want to keep the same IP addresses on both sites, but also want to reduce the risk of having duplicate IPs on the same network.

How can this be accomplished?

A. The non-production site interface must be manually configured to be off-line. During a failover, the interface must be manually configured to be on-line.

B. The non-production site interface must be manually configured to be off-line. During a failover, the interface will automatically go on-line.

C. There is no need for manual manipulation of the interfaces during a failover operation.

D. Interfaces on both sites can be up but DNS cache must be flushed during a failover.
