Symmetrix Solutions Expert Exam for Storage Administrators

A system administrator needs to migrate all virtual machines in a vSphere datastore from an EMC Symmetrix DMX3 to a VMAX. The virtual machines will be migrated individually to minimize the impact to the ESX hosts. The virtual machines must remain online during the migration.

Which migration approach meets all the objectives?

A company is using Replication Manager to back up multiple Microsoft Exchange 2010 mailbox servers.
They have configured a backup job defining the options for performing VSS backups of each Exchange storage group on each server. All backups are executing successfully, but the company has recently started to experience problems with low disk space on the transaction log volume of one particular storage group.

What is the likely cause for the low disk space?

The exhibit shows the current port flag settings for a Symmetrix VMAX FA port.

Will the current settings allow Symmetrix VMAX storage to be successfully presented to a VMware vSphere ESXi server and why?

A storage administrator is configuring Optimizer on an EMC Symmetrix VMAX array. The array is configured entirely with RAID 5 (3+1) devices. All devices are 8 GB and all devices are R1 devices with SRDF/A mirrors on a remote array.

Optimizer has completed the first cycle of performance analysis and has recommended a large number of device swaps to balance the activity on the array. The storage administrator has been asked to minimize the time it takes to complete all the swaps.

What is the minimum configuration of DRV devices that the administrator needs to create?

A company requires their ESXi server to boot from an EMC Symmetrix VMAX device over the SAN.

What is a consideration?

Refer to the Exhibit.

A company has an EMC Symmetrix with remote protection. Data-at-rest encryption (DARE) is installed at the primary site.

What is required to secure information on the SRDF links?

A database administrator is concerned about the performance impact of placing a busy Oracle instance in hot backup mode. They want to take TimeFinder/Clone consistent replicas every three hours.

If Oracle is not placed in hot backup mode, what is the state of the Oracle tablespaces in the replica?

EMC Symmetrix VMAX devices 0AB and 019 are allocated to a UNIX server:

The storage administrator found that the utilization of device 019 is much higher than device 0AB.

How is the write pending limit allocated?

An EMC Symmetrix VMAX is shared between a company's sales and engineering departments. The company has the following requirements:
1. A specific user from the sales department should be allowed to execute TimeFinder commands on the devices set aside for sales using a Solaris host.
2. The same user should not be allowed control over devices belonging to engineering.
3. No other user with an account on the Solaris host should be able to exercise the same controls specified in the first two requirements.

Which combination of access control permission and user-based authorization role will fulfill this requirement?

When formatting Symmetrix volumes for use with Microsoft SQL Server online transaction processing databases, which allocation unit size should be selected?
