A customer plans to deploy Oracle on their new Symmetrix VMAX. They are concerned about the performance of the redo log files. You recommend isolating these files to their own set of disks and deploying them on striped metavolumes.
Why would you recommend striped metavolumes?
A. Write pending limit is higher
B. Actuator contention is reduced
C. Random read response is improved
D. Spindle queue depth is increased
A customer is planning an Oracle 11g implementation. You have been asked to design the Oracle storage architecture. You recommend placing redo log files on separate drives from other Oracle files. Your customer wants an explanation of this architecture choice.
What best describes the reason for this EMC recommendation?
A. Redo logs' write performance can affect the performance of the entire database
B. Separation ensures that disk failure will not result in losing the entire database
C. Redo logs on the same drives as the Oracle data files is not supported
D. Redo logs' read performance can affect the performance of the entire database
You have been assigned to gather performance data for a Microsoft SQL server database that will be migrated to a Symmetrix VMAX. Which Perfmon counter must be measured prior to designing a disk layout?

B. Physical Disk\Avg. Disk sec/Write
C. Logical Disk\Avg. Disk Bytes/sec
D. Logical Disk\Disk Write Bytes/sec
A customer is planning a new Microsoft Exchange 2010 environment on their Symmetrix VMAX. The customer wants to know how they can backup volumes containing active mailbox databases.
What advice should be provided to the customer?
A. Use the VSS plug-in that ships with Exchange 2010 or Replication Manager.
B. Only Replication Manager or a third-party Exchange-aware VSS-based application can be used.
C. Only the VSS plug-in that ships with Exchange 2010 can be used.
D. Create Custom backup scripts.
A customer is planning a new Microsoft Exchange 2010 environment on their Symmetrix VMAX. The customer wants to know how they can backup volumes containing passive mailbox database copies.
What advice should be provided to the customer?
A. To use Replication Manager or a third-party Exchange-aware VSS-based application.
B. Only the VSS plug-in that ships with Exchange 2010 can be used.
C. VSS plug-in that ships with Exchange 2010 or Replication Manager can be used
D. To create Custom backup scripts.
Your customer is using Replication Manager to make local TimeFinder/Clone backups of their Microsoft Exchange 2010 environment. The customer reconfigured the Exchange environment to place the logs on the L:\ drive and mount the database on L:\SG1DB1. They updated the associated Replication Manager replica job to reflect the change. The customer reports that the mount of the database to the backup server now fails.
What do you advise the customer?
A. Nested mount points are not supported with Replication Manager.
B. A separate application set must be configured for the database.
C. Additional clone targets need to be added to the storage pool.
D. The database replica must be part of the same replica job as the logs.
A customer recently reconfigured their Microsoft Exchange 2010 environment. They placed the log and system files on the L:\ drive and mounted the mailbox stores on L:\SG1DBMP. The customer reports that they updated the associated Replication Manager replica job to reflect the change. However, the mounts to the backup server fail.
What should you advise the customer?
A. Mount both the logs and database to separate mount points within a folder on the C. drive
B. Additional clone targets need to be added to the storage pool.
C. Log and system files on same volume are not supported.
D. The mailbox store replica must be part of the same replica job as the log files.
A customer is implementing a Microsoft Exchange environment on a Symmetrix VMAX. The environment will be deployed on 600 GB FC 15K drives using RAID 5 data protection. The application generates 2000 I/ O per second with an I/O pattern that is 75% reads and 25% writes. What is the minimum number of drives recommended to support the application?
B. 18
C. 24
D. 32
A company plans to deploy Symmetrix VMAX arrays in their VMware vSphere environment. The ESXi hosts will be connected to the VMAX arrays over a FC SAN.

B. SPC-2
C. Unique worldwide name (UWN)
D. Common Serial Number (C)
