EMC Technology Foundations e20-322 Web Demo
This webdemo is just a demo data, only for reference and learning, there is no other purposes
1. A customer has a SAN fabric consisting of several MDS-9509s for host to disk array connectivity.
They have purchased a Fibre Channel tape library and want to implement
LAN-free backups. You have proposed making a tape VSAN on the existing
MDS infrastructure and have recommended that they use QoS so that tape
I/O does not use ISL bandwidth at the expense of disk I/O.
Which license is needed on the MDS directors?
A. Enterprise package
B. Fabric Manager Server
C. Storage Services Enabler package
D. Tape Write Acceleration package
Answer: A
2. A prospective customer has presented you with multiple applications.
All applications have high write activity levels and unpredictable
growth patterns. The applications are currently hosted on
direct-attached storage in a RAID 1 configuration. They are concerned
with making too many
changes at one time in their environment.
The prospect has asked you to justify your recommendation of RAID 1/0
on the CLARiiON configuration you are proposing. How do you respond to
the request?
A. RAID 1 has a higher write penalty than RAID 1/0
B. RAID 1 is less flexible for growing LUNs than RAID 1/0
C. RAID 1 is unavailable in current CLARiiON configurations
D. RAID 1 LUNs are unable to utilize write cache
Answer: B
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

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
5. 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.
