A customer plans to move a performance-sensitive application to a new EMC VNX with all SAS drives. The application will reside on an NFS export, and the customer requires the file system provide consistent performance. The customer also needs to create additional CIFS shares, which do not share the same performance requirement. How should both sets of file systems be created?
A. Place four dvols in a user-defined pool for the NFS-exported file systems and let AVM manage the CIFS file systems with system-defined pools.
B. Place five dvols in a user-defined mapped pool for the NFS-exported file systems and let AVM manage CIFS file systems with system-defined pools.
C. Place four dvols in a system-defined pool for the NFS-exported file systems and let AVM manage the CIFS file systems with user-defined pools.
D. Place five dvols in a system-defined mapped pool for the NFS-exported file systems and let AVM manage the CIFS file systems with user-defined pools.
A DBA wants to create a replicated, recoverable copy of an Oracle 11g database environment that will reside on a number of EMC VNX target drives.
The DBA performs the following:
-Puts the required tablespaces in hot backup mode
-Issues a checkpoint to the database
-Synchronizes and fractures the Oracle device pairs
-Ends hot backup mode
-Brings the replicated copy online
What action must the DBA take to enable the copy to start up successfully?
A. Apply the Archive Logs
B. Vary on the volume groups on the target volumes
C. Copy the master Init.ora file to the target volume
D. Copy the Oracle control file to the target
An Oracle DBA creates a new database and requests a LUN to store the online redo logs. What is the recommended configuration for this LUN?
A. RAID 1/0 using SAS drives
B. RAID 5 using Flash drives
C. RAID 1/0 using Flash drives
D. RAID 5 using SAS drives
A hospital wants to configure a tiered pool on an EMC VNX to support a vSphere ESXi 5.0 environment with fifteen hosts. Which disk layout is supported for a tiered pool?
A. 4 Flash drives RAID 1/0, 5 SAS RAID 5, 5 NL-SAS RAID 5
B. 4 Flash drives RAID 1/0, 5 SAS RAID 5, 6 NL-SAS RAID 6
C. 5 Flash drives RAID 5, 5 SAS RAID 5, 5 NL-SAS RAID 5
D. 5 Flash drives RAID 1/0, 5 SAS RAID 5, 6 NL-SAS RAID 6
A customer has DR enabled between their primary and backup sites using EMC VNX and MirrorView. SnapView Snapshots are enabled at the backup site. A third VNX array is installed at the backup site. The customer tries to use Incremental SAN Copy (ISC) to pull data updates from a SnapView snapshot onto stopped Web server LUNs located on the new VNX. The customer reports they are not able to configure the SAN Copy session.
Why does the customer need to rework this solution?
A. The source for Incremental SAN Copy must be on the secondary mirror, and the mirror needs to be fractured.
B. The source for Incremental SAN Copy must be on the primary mirror, and the mirror needs to be in synchronizing state.
C. The source for Incremental SAN Copy must be on a SnapView snapshot from the synchronizing primary mirror.
D. The source for Incremental SAN Copy must be on a SnapView snapshot from the fractured secondary mirror.

A client has a storage requirement for an object database. The application is expected to generate random I/O requests. The I/O profile is:
-70% random reads
-30% random writes
-Total host I/O per second is 20,000
-Required usable capacity is 35 TB
The client is concerned about cost, so RAID 5 (8+1) data protection will be used. What is the minimum number of 300 GB 15K SAS drives needed to meet the client's performance and storage requirements, including hot spares drives?
A. 223
B. 166
C. 292
D. 238
An EMC VNX supports several iSCSI Windows hosts, as well as a home directory structure for fifty CIFS clients. The iSCSI hosts run an application with an I/O pattern that is 80% writes with a 2 MB I/O size. The customer reports overall write performance is less than expected. Your examination of the VNX reveals frequent forced flushing. Which recommendation is most likely to improve performance for the home directory clients?
A. Increase the high watermark to 90%
B. Change the write-aside value to 1023 KB
C. Use a pre-fetch multiplier greater than the segment multiplier
D. Split the iSCSI and file workloads to different LUNs
A vSphere ESXi v5.0 administrator receives an alert that a VM (virtual machine) has been paused. What action should they take to resume this VM's operation?
A. Add additional storage to the thin-provisioned storage of the VM.
B. Restart a fractured MirrorView replication session on the VM's datastore.
C. Restore a failed network link on the ESXi server's teamed network interface adapters.
D. Ensure that one of the VM's applications is not pinned to a failed vCPU.
A healthcare company uses MirrorView replication between VNX located at their two data centers. They use the Write Intent Log (WIL) feature on both VNX. There was an outage at the production data center and production workload was transferred to the DR data center. When then production workload was failed back to the production data center, the customer found all MirrorView LUNs completed a full resynchronization. What caused this situation?
A. The WIL information is stored on the SP Cache and was lost during the outage of the production data center.
B. The WIL information was lost during the production data center outage and a full re- synchronization of all the LUNs was required.
C. The WIL information was not transferred from the production data center to the DR data center after the outage.
D. The WIL information is non-relevant after the MirrorView secondary images have been promoted to primary image.
A customer asks you to design an EMC VNX for an Oracle database composed of 300 GB RAID 1 and 600 GB RAID 5 (4+1) drives. Which configuration provides maximum usable capacity balanced with reasonable performance?
A. Place the Redo log and Archive log files on RAID 1. Place the Control and database files on RAID 5.
B. Place the Control and database files on RAID 1. Place the Redo log and Archive log files on RAID 5.
C. Place the Control, Redo log, and Archive log files on RAID 1. Place the database files on RAID 5.
D. Place the database files on RAID 1. Place the Control, Redo log, and Archive log files on RAID 5.
