A composite group spanning two Symmetrix arrays is set up to run SRDF/Star using Cascaded
SRDF as illustrated in the exhibit. Which condition must be met before an MSC cycle switch is
performed at site B?

Refer to the exhibit.

A customer has four Symmetrix logical volumes assigned to a host for a specific application. The
Symmetrix has FAST enabled and configured for performance management. Which Symmetrix
logical volume will be the first swapped to a higher performance tier?

Refer to the exhibit.

In the SRDF/Star environment shown in the exhibit, what is the result of issuing the symstar halt
command from the host at the workload site?

Refer to the exhibit.

A company has three data centers that they use to run Concurrent SRDF/Star. Due to a network
problem, links between the workload and synchronous target sites have become unavailable.
Which diagram accurately reflects the status of the Concurrent SRDF/Star configuration?

Refer to the exhibit.

In a Cascaded SRDF/Star environment, Site B fails. The surviving sites are reconfigured to enable
remote data protection. What is used to determine the invalid tracks that must be moved from Site
A to Site C?

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 “N:\”.
You have decided on RAID-5 protected 15,000 RPM drives for the new SQL database and RAID-1
for the transaction log.
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 87 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 customer is planning to replace an end-of-lease DMX-2500 with a new two engine VMAX.
Because the customer has reported some performance issues with the DMX, you have been
asked to analyze the DMX and recommend the VMAX configuration. This customer’s plan is for
10% growth over the next 24 months. The DMX has 256GB cache and 380 x 300GB-10K FC
drives. To avoid past performance issues but keep the cost low, which configuration should be
recommended?

Refer to the exhibit.

A company plans to deploy a one engine Symmetrix VMAX array in their VMware vSphere
environment. The ESXi hosts will be connected to the VMAX array over a FC SAN. What is the
recommended best practice when zoning an ESXi host with two HBAs to the VMAX?
