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 5874 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?
B. FAST VP
C. Symmetrix Priority Controls
D. Virtual Provisioning
A company is planning to deploy Enterprise Flash Drives (EFDs) in their EMC Symmetrix VMAX array. When using devices on the EFDs, which I/O profile will benefit the most?
A. High random reads
B. Sequential reads
C. High random writes
D. Sequential writes
A company requires their ESXi server to boot from an EMC Symmetrix VMAX device over the SAN. What is a consideration?
A. Boot controller should be in the lowest-numbered PCI slot on the server.
B. Boot LUN must have a logical unit number between 10-20.
C. Boot LUN must have only one path from the Symmetrix VMAX.
D. Boot LUN must have RAID 5 protection.
A company is managing their VMware vSphere environment from a Microsoft Windows host. They want to use EMC Virtual Storage Integrator Storage Viewer and Path Management plug-ins. Which software should be installed on the Windows host before installing the VSI plug-ins?
A. Solutions Enabler (32 bit)
B. Solutions Enabler (64 bit)
C. Solutions Enabler (32 bit) and PowerPath/VE Remote Tools
D. PowerPath/VE Remote Tools
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. Move the application’s LUNs to more lightly utilized disks to bring overall response time down.
B. Double the number of drives on the director loop to increase the available capacity.
C. Double the size of the drives used to reduce overall drive capacity usage.
D. Adjust the application I/O to a larger size to increase its throughput while reducing IOPS.
A company has been creating TimeFinder/Clone replicas of several Microsoft Exchange 2010 mailbox servers using Replication Manager. They have recently added a new Exchange Server 2010 mailbox host to the environment. In addition, the company has created a scheduled job to create replicas of five storage groups in consecutive order. They notice that the newly added replica jobs seem to take a long time to complete. What is the source of the problem?
A. NTFS volumes containing the databases were not formatted with the correct cluster size
B. Replication Manager job should have been configured to create the replicas simultaneously
C. Latest Replication Manager Client Service Pack was not installed on the Exchange server
D. Exchange management utilities were not installed on the Replication Manager mount host
A company must deploy Symmetrix Access Control restricting access to hosts that belong to the ADMIN group. Which two default Symmetrix Access Control Entries (ACE) must be removed to restrict access to hosts that do not belong to the ADMIN group?
A. BASE from group UnknwGrp for ALL devices.
ALL from group UnknwGrp for non-pooled devices.
B. BASECTRL from group UnknwGrp for ALL_DEVS.
ALL from group UnknwGrp for INPOOLS devices.
C. HostID from group UnknwGrp for ALL_DEVS.
ALL from group UnknwGrp for INPOOLS devices.
D. HostID from group UnknwGrp for ALL devices.
ALL from group AdminGrp for non-pooled devices.
Prior to creating your Symmetrix VMAX architecture for SQL, you are given a Perfmon Log view containing data for your database LUN. The file contains read and write IOPS collected over the past week, at 3-minute intervals. Which method should be used to determine the correct IOPS target for calculating the appropriate number of RAID corrected spindles?
A. 75th percentile
B. 90th percentile
C. Overall Average
D. Overall Peak
Four DRV devices are configured on an EMC Symmetrix VMAX array. As per current settings, a maximum of four simultaneous swaps and eight swaps per day are allowed in the Symmetrix. Optimizer analyzes the back-end I/O and decides to swap. How many swaps are allowed at the same time?
