Question 1

Click on the calculator icon in the upper left corner. A customer would like to add a new database application to their VMAX. This application is expected to produce 3000 I/O per second with 45% read hit and 25% write. The customer expects to use RAID 5 (3+1) on new drives that are not yet utilized. These drives perform 100 SCSI commands per second (read/writes) at 100% utilization.
Assuming drive utilization should not exceed 70%, how many physical drives, excluding hot spares, does the customer need to achieve performance requirements?

A. 56 disks B. 32 disks C. 68 disks D. 48 disks

Question 2

A customer is implementing Replication Manager to create local clone replicas of their SQL database on their VMAX array. The customer is concerned the RM replica jobs may run for an extended period of time and could cause resource conflicts with other production applications. How can the customer best minimize the impact of the RM replica jobs on the array?

A. Stagger the replica jobs and run them during off-peak hours. B. Run the replica jobs simultaneously and during off-peak hours. C. Stagger the replica jobs and run them during peak hours. D. Run the replica jobs simultaneously and during peak hours.

Question 7

Your customer has an Oracle 11g environment that requires a database to be recoverable within a few minutes over an extended distance. Which best practice would you recommend to ensure recoverability on the target side?

A. Using SRDF/A across the RDF link, apply the redo logs on the target side after the split B. Enable Archive Log mode on the production database; enable SRDF/A across the RDF link; split the RDF link (consistent); and apply the archive logs on the target side. C. Enable SRDF/AR for full source-to-target synchronization at the bunker site D. Enable SRDF/S for full source-to-target synchronization. After the RDF split, apply the redo logs to ensure recoverability

Question 8

Click on the calculator icon in the upper left corner. Refer to the exhibit.

You are designing the Symmetrix VMAX architecture for a DAS-to-SAN SQL Server migration. Currently all user databases reside on a single locally attached disk enclosure, mounted to "M:\". You have decided on RAID-1 protected 15,000 RPM drives for the new SQL environment.
Last week, you configured Perfmon to record the current IOPS load of the databases during the 8-hour business day, Monday thru Friday as shown in the exhibit. During an average business day, the transaction log processes 43 GB worth of data.
Following EMC best practices, what is the minimum number of spindles that must be allocated for optimal transaction log performance?

A. 6 B. 10 C. 2 D. 4
