A storage resources takes 10ms to service a request when there are no other requests in its
queue. What would be the new service time, according to Little’s Law, if the resource were 80%
utilized?

ABC.com is planning to migrate data from an 8530 to a CX700. Both arrays are in the same SAN.
A script will be crated to setup and start the SAN copy sessions. After zoning the 8530 ports to the
CX Sp-ports, what other dependencies must be completed prior to setting up the SAN copy
sessions?

Customer applications are running HP-UX servers attached to a CX700. The CLARiiON LUNs
currently used by the application are 50GB metalLUNs. The applications require more disk space.
Expansion of the CLARiiON metaLUNs to 100GB has been proposed. What additional information
is critical to the success of this solution?

You are a designer for ABC.com. ABC.com requires you to analyze a performance problem. After
conducting a root cause analysis, you trace the problem to the layout of the database across the
backend of the storage device. This is a characteristic of which type of solutions design
engagement?

ABC.com environment consists of 25 UNIX and 15 Windows servers. All of the servers have either
internal storage or direct attached storage. These servers are used for file sharing, home
directories and custom applications. You need to get a complete picture of the customer’s servers
in order to propose a storage solution. Which method of data collection provides the most
complete picture of the customer’s servers?

Delta Devices 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. The customer 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?

You are a designer for ABC.com. As a result an audit of their overall business processes,
ABC.com must now implement increased security for its Symmetrix environment. Which actions
can best improve the security at the logical volume level on the Symmetrix in ABC.com’s SAN?

What are the major characteristics of a tactical solutions design engagement?

In your capacity as a designer for ABC.com, You have been asked to design a new centralized
backup solution. ABC.com has forwarded a list that consists of the number of servers, the amount
of data, the daily change rate, and information about the backup policy. ABC.com does not want to
change its current backup policy. What other essential piece of information will you need to
correctly size the solution in terms of throughput requirements?

ABC.com has an imaging application and is currently capturing images of its contracts, saving
them to tape, and shipping them to a secondary datacenter for offsite storage. The government
requires ABC.com to hold on to certain records, but the local administrator informs you that he has

that ABC.com recently lost a storage administrator and that the three remaining administrators are
overworked. He also described how ABC.com’s business has been growing rapidly, and that they
are preparing to purchase a new tape silo for their environment. In addition, the CIO complains
about tape corruption issues and rising tape management costs. Which edition of Centera is best
for ABC.com?
