You recommended an ILM strategy to ABC.com, and received a reply that they already have ILM
implemented. ABC.com’s policy is to retain data on Symmetrix and then archive it to optical disk
after a year. Why is ABC.com’s process defective according to ILM principles?

ABC.com is planning to migrate its data and Windows hosts from an existing CLARiiON array to a
DMX in its enterprise SAN. ABC.comwould like to complete the migration with the least amount of
downtime and no host involvement. What migration method is considered the best for achieving
the desired objectives, while adhering to the design considerations?

You have been tasked with assessing ABC.com’s Exchange environment that is experiencing a
performance issue with its Microsoft Exchange environment. Your idea is to compare the results of
the assessment to Microsoft best practices. What is the best tool to use to achieve this?

You are a designer for ABC.com. ABC.com is keen on a solution that offers detailed reports on all
the files, filesystems, Oracle databases, SQL Server databases and Exchange Servers in its
environment. To design a suitable solution, which of the following information must you collect?

ABC.com, whohas a Windows 2003 database environment, notices that the performance of their
CLARiiON LUNs is lower than expected. Even though the workload has not increased in the last
six months, the performance has declined steadily. For a full working day, you collect Analyzer
data that proves ABC.com’s observations. Which combination of problems is probably the reason
for this poor performance?

ABC.com is using TimeFinder/Snaps for its daily reports on a database that has several LUNs for
data and logs. The report generation runs on a secondary host. The application cannot be
quiesced without downtime. How can you eliminate the downtime, and still ensure that a

restartable copy is available for report generation?

ABC.com has a CX700 SAN for its Microsoft application environment. During the implementation
of SnapView, you find that the Microsoft file systems are misaligned on the production LUNs. The
file systems have to be aligned before employing SnapView for these hosts. Host downtime must
to be kept to a minimum. Which method would achieve the desired objectives best?

What are the most important metrics to use for storage performance reporting in the
Hosts/Application tier?

You are a designer for ABC.com. ABC.com needs to archive data as unalterable sets of files,
which have to be available to both UNIX and Windows clients. What technology do you
recommend to satisfy this requirement?

ABC.com has contacted EMC to solve its backup infrastructure problem. Its current backup
infrastructure consists of several different types of backup software and tape drives, dedicated to
its own servers. After several meetings you designed a centralized backup infrastructure,
implementing backup to disk technology. ABC.com is very concerned about disaster recovery
times. You propose one CX500 with ATA disks to be used onsite, at the primary location, and
another CX500 at a secondary location so backup data can be replicated from one CLARiiON to
the other one through the WAN. This will ensure that the backup data will be available in case of a
major disaster with the primary location. What other action should be taken?
