EMC Symmetrix Solutions Design Exam for Technology Architects Sample Questions:
A proposed SRDF/S solution was modeled with BCSD using host-based data. The BCSD model assumed two-engine VMAX arrays with SRDF Fibre ports. The Compressed Throughput chart shows that the available throughput is greater than the peak throughput. The Volume Exceptions table lists ten devices.
What should be recommended?
- A. Provide more bandwidth
- B. Change the application layout
- C. Turn off software compression on the remote adapters
- D. Use three-engine VMAX arrays
Refer to the exhibit
What is a characteristic of the proposed configuration recommended by TierAdvisor?
- A. It will cost 2% more than the current configuration
- B. It will use 6% less storage capacity than the current configuration
- C. For compatibility with FAST the tier allocations must add up to more than 100%
- D. It will have 51% better response time than the current configuration
When using Clone Emulation, which TimeFinder/Clone command represents the symmir establish command?
- A. symclone create -precopy -incremental
- B. symclone create -precopy -differential
- C. symclone establish -copy
- D. symclone activate -copy
Refer to the exhibit.
A customer has a legacy DMX-3 at Site 1, where a BCV-R1 copy is taken of the production volumes and then replicated to another DMX-3 at Site 2 via SRDF/A. The customer will replace the legacy DMX-3 arrays at both sites with new VMAX arrays.
The customer wants to enable concurrent SRDF on the Site 1 SRDF source volumes, to maintain disaster restart protection between the legacy DMX-3 arrays and migrate the legacy DMX-3 at Site 1 to the new VMAX array. What should you advise the customer?
- A. Concurrent SRDF migration is not supported for this configuration.
- B. Enable concurrent SRDF using SRDF/A from the BCV-R1.
- C. Host level migration is the only migration option for this configuration.
- D. Enable concurrent SRDF using SRDF/S from the BCV-R1.
A customer is planning an Oracle 11g implementation. You have been asked to design the Oracle storage architecture. You recommend placing redo log files on separate drives from other Oracle files. Your customer wants an explanation of this architecture choice.
What best describes the reason for this EMC recommendation?
- A. Separation ensures that disk failure will not result in losing the entire database
- B. Redo logs on the same drives as the Oracle data files is not supported
- C. Redo logs' write performance can affect the performance of the entire database
- D. Redo logs' read performance can affect the performance of the entire database
