Exam: Technology Architect Solutions Design

1. A customer is deploying a new Microsoft Exchange environment and has requested assistance with the
associated disk design. They are deploying Exchange for 850 users with an average of 3 I/Os per user.
They expect a 60% read and 40% write distribution.
The customer would like to know the number of disks required for both RAID 5 and RAID 1/0 DMX
configurations with 15k rpm drives. How many disks are required for each configuration type?
A. RAID 5 28 and RAID 1/0 18
B. RAID 5 31 and RAID 1/0 20
C. RAID 5 38 and RAID 1/0 24
D. RAID 5 43 and RAID 1/0 28
Answer: A

2. A customer plans to create two regional offices that are between 800 and 2,000 km away from their
main data center. Each regional office will have a data center that will serve four to six branch offices
between 30 and 50 km away.
At the close of business each evening the customer will shut down the application and transmit changes
to each regional office. The amount of new information sent from the head office each night will vary from
0.5 and 1.5 GB. Later each night, an application at the regional offices will read the data from the head
office and generate approximately 50 MB of new rate information appropriate for its branch offices.
What is the most cost-effective EMC solution?
A. 1. Configure CLARiiON arrays in each office.
2. Use MirrorView/A and T3 networks for all data transfers.
B. 1. Configure Symmetrix arrays in the head office and CLARiiONs in the regional offices.
2. Use OC-3 networks to transmit the same master copy of data from the head office to the regional
offices using Open Replicator.
3. At the regional offices, create a snap of the data received and transmit the changes to the branch
offices using SAN Copy.
C. 1. Configure Symmetrix arrays at all the main data centers and CLARiiONs at the regional and branch
offices.
2. Use OC-3 network links between the main data centers.
3. Use DS-3 between the regional and branch offices.
4. Use SRDF/DM for data transfer in each case.
D. 1. Configure Symmetrix arrays at the head office and regional offices.
2. Configure CLARiiONs at the branch offices.
3. Use SRDF/DM and T1 network links between the head office and regional offices.
4. Use Open Replicator incremental offline push to distribute rate information to the branch offices
using T1 network links.
Answer: D

3. A customer decided to consolidate their storage onto a Symmetrix. They have a mix of Windows and
UNIX servers and want one copy of data for creating backups each night. They also want another copy to
be made during the day. This second copy will be a standby to perform a fast recovery in the event of data
corruption.
The initial survey of the customer environment shows that the read/write ratio of their application is 1. 2                                                                                                                                                                                                                                                                             during the day and 5. 1 at night. The application appears to be highly sensitive to disk response times
during the day.
Which initial solution should be considered?
A. TimeFinder/Clones for the standby copy and TimeFinder/Mirror BCVs for backups at night
B. TimeFinder/Snap for the standby copy and TimeFinder/Clone for backups at night
C. TimeFinder/Snap for the standby copy and TimeFinder/Mirror BCVs for backups at night
D. TimeFinder/Mirror BCVs for the standby copy and TimeFinder/Snaps for backups at night
Answer: D

4. A customer has implemented a second Brocade director into their environment. They have moved
several hosts and one of their two storage arrays onto the new director. When a large batch cycle was run,
the customer experienced queuing on the directors when previously there was none.
The customer discovered the following during their analysis of the issue.
The hosts running the batch cycle used storage from both arrays.
The only LUNs having problems came from the array attached to the new director.
When the batch process was re-run with all LUNs made available through the original director, no
problems were encountered.
What would you recommend to solve the performance problem?
A. Add departmental switches to the fabric, creating a core/edge design
B. Change FSPF costs
C. Implement additional Brocade ISLs
D. Utilize Brocade ISL Trunking to optimize the ISL traffic
Answer: D

5. You are designing an EMC ControlCenter solution for a new customer to reduce the overall storage and
management costs. The customer would like management and reporting on a variety of hosts and
storage systems. All managed objects are located in one data center.
Which factors must you consider when designing an EMC ControlCenter infrastructure?
A. Network firewall type, number of hosts, and total storage capacity
B. Network firewall type, number of IP switches, and number of Fibre Channel switches
C. Network latency, number of Exchange servers, and number of Oracle database
D. Network latency, number of hosts, and number of arrays
Answer: D
