1. A customer is deploying a new Microsoft Exchange environment and has requested assistance with the
\nassociated disk design. They are deploying Exchange for 850 users with an average of 3 I\/Os per user.
\nThey expect a 60% read and 40% write distribution.
\nThe customer would like to know the number of disks required for both RAID 5 and RAID 1\/0 DMX
\nconfigurations with 15k rpm drives. How many disks are required for each configuration type?
\nA. RAID 5 28 and RAID 1\/0 18
\nB. RAID 5 31 and RAID 1\/0 20
\nC. RAID 5 38 and RAID 1\/0 24
\nD. RAID 5 43 and RAID 1\/0 28
\nAnswer: A
\n2. A customer plans to create two regional offices that are between 800 and 2,000 km away from their
\nmain data center. Each regional office will have a data center that will serve four to six branch offices
\nbetween 30 and 50 km away.
\nAt the close of business each evening the customer will shut down the application and transmit changes
\nto each regional office. The amount of new information sent from the head office each night will vary from
\n0.5 and 1.5 GB. Later each night, an application at the regional offices will read the data from the head
\noffice and generate approximately 50 MB of new rate information appropriate for its branch offices.
\nWhat is the most cost-effective EMC solution?
\nA. 1. Configure CLARiiON arrays in each office.
\n2. Use MirrorView\/A and T3 networks for all data transfers.
\nB. 1. Configure Symmetrix arrays in the head office and CLARiiONs in the regional offices.
\n2. Use OC-3 networks to transmit the same master copy of data from the head office to the regional
\noffices using Open Replicator.
\n3. At the regional offices, create a snap of the data received and transmit the changes to the branch
\noffices using SAN Copy.
\nC. 1. Configure Symmetrix arrays at all the main data centers and CLARiiONs at the regional and branch
\noffices.
\n2. Use OC-3 network links between the main data centers.
\n3. Use DS-3 between the regional and branch offices.
\n4. Use SRDF\/DM for data transfer in each case.
\nD. 1. Configure Symmetrix arrays at the head office and regional offices.
\n2. Configure CLARiiONs at the branch offices.
\n3. Use SRDF\/DM and T1 network links between the head office and regional offices.
\n4. Use Open Replicator incremental offline push to distribute rate information to the branch offices
\nusing T1 network links.
\nAnswer: D
\n3. A customer decided to consolidate their storage onto a Symmetrix. They have a mix of Windows and
\nUNIX servers and want one copy of data for creating backups each night. They also want another copy to
\nbe made during the day. This second copy will be a standby to perform a fast recovery in the event of data
\ncorruption.
\nThe initial survey of the customer environment shows that the read\/write ratio of their application is 1. 2
\nduring the day and 5. 1 at night. The application appears to be highly sensitive to disk response times
\nduring the day.
\nWhich initial solution should be considered?
\nA. TimeFinder\/Clones for the standby copy and TimeFinder\/Mirror BCVs for backups at night
\nB. TimeFinder\/Snap for the standby copy and TimeFinder\/Clone for backups at night
\nC. TimeFinder\/Snap for the standby copy and TimeFinder\/Mirror BCVs for backups at night
\nD. TimeFinder\/Mirror BCVs for the standby copy and TimeFinder\/Snaps for backups at night
