ABC.com is running four applications (A, B, C, and D) daily as follows: “A” has its consistent peak
workload of 65K IOPS with an average 4KB blocksize for 4 hours from 9am. “B” has its consistent
peak workload of 20K IOPS with an average 8KB blocksize for 3 hours from 8am. “C” has its
consistent peak workload of 50K IOPS with an average 4KB blocksize for 4 hours from 10am. “D”
has its consistent peak workload of 10K IOPS with an average 8KB blocksize for 2 hours from
11am. From a performance viewpoint, what is the minimum number of 2Gbit array ports into a
single array would you suggest to handle both this workload and 25% growth?

What is the classic formula for calculation percentage availability?

of the following is true for this situation?

ABC.com needs to add NAS capability to use excess capacity in its CLARiiON storage array. It
has 140 Windows Servers, which are all at least three years old. There is a total of 8.2TB of

Which Celerra model would be the best to propose?

An engagement with a mobile device manufacturer has yielded a solution that includes several
storage arrays and controlcenter. As part of the solution EMC will provide system integration and
training.
What is the scope of this solution?

ABC.com’s backup policy, for part of its environment consists of weekly fulls and daily incremental.
After a virus attack, the system administrator was forced to reintall a server and perform a full data
recovery. As a result different sets of tapes (one full and several incrementals) were required and

the recovery tool a long time to complete. What can be done to reduce the time it takes to
complete a full recovery in the future?
