You are examining the performance of a weekly backup. You notice that the utilization for the Symmetrix front-end director CPUs involved in the backup is very low.
What might be causing this low utilization?

• A.Backup application is executing an equal number of reads and writes
• B.Data access is random
• C.Backup application is using a large I/O block size
• D.Data is stored on RAID 1-protected devices

An application hosted on the Symmetrix is experiencing increasingly longer processing times. However, the data has not changed in several months. New servers are being added regularly to the array, some of which are also experiencing poor performance.
Performance Manager shows an unbalanced back-end. How could this be resolved?

• A.Double the number of drives on the director loop to increase the available capacity
• B.Move the application's LUNs to more lightly utilized disks to bring overall response time down
• C.Adjust the application I/O to a larger size to increase its throughput while reducing IOPS
• D.Double the size of the drives used to reduce overall drive capacity usage

What is the finest level of backup granularity provided by Replication Manager for Microsoft SQL Server?

• A.Database Filegroup
• B.Database Table
• C.Database Server
• D.Database Instance

You have been tasked with gathering performance data for a Microsoft SQL Server database that resides on a Symmetrix VMAX LUN. Which Perfmon counter must be used to collect the write IOPS metric?

• A.Physical Disk\Avg. Disk sec/Write
• B.Logical Disk\Avg. Disk Bytes/sec
• C.Physical Disk\Disk Writes/sec
• D.Logical Disk\Disk Write Bytes/sec

A storage administrator is planning to configure an EMC Symmetrix VMAX array for a few critical Microsoft Windows application servers. The array is running Enginuity 5875 and has a mixture of SATA, FC, and EFD disks installed. The application servers all require a mix of high performance and low performance capacity.
Which Symmetrix feature should be used to ensure the most dynamic and efficient use of the array with the best performance possible for all applications?

• A.Symmetrix Priority Controls
• B.FAST
• C.Virtual Provisioning
• D.FAST VP
