A customer is deploying an Exchange 2010 environment on an EMC VNX. There will be 30,000 mailboxes distributed across mailbox servers within a DAG (database availability group) that maintains three database copies. Each user sends approximately 350 messages per day. The customer wants to use 600 GB 15K drives in a RAID 5 group. How many spindles are needed to support the performance required for this Exchange environment?
A. 197
B. 132
C. 158
D. 175
You review a Perfmon log that contains several days worth of data for a customer's SQL Server database LUN. The log contains both read and write I/O per second collected at 3-minute intervals.
What method should you use to determine the correct I/O per second target number for calculating the number of RAID corrected spindles?
A. 75th percentile
B. Overall Peak
C. Overall Average
D. 90th percentile
An ISP will provide infrastructure to clients as part of a cloud computing strategy. They are concerned about their storage requirements and supporting the many small customer environments targeted by their marketing campaign.

C. Maintains database changes until it is written out to the redo log files on the disk
D. A set memory structure and a number of system processes
A customer configures SnapView clones on their EMC VNX. A 256 GB clone is fractured for 10 minutes. The source LUN performs fifty 32 KB random writes per second. The clone resynchronization is configured to 6 MB/s. How long will it take to resynchronize the clone?
A. 10.5 minutes
B. 21.0 minutes
C. 35.0 minutes
D. 60.0 minutes
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. VDMs are not configured on the secondary site.
B. The CIFS service is not running on the secondary site.
C. Source side file systems are not correctly sized.
D. Source side VDM Replication licensing is not enabled.
