EMC Symmetrix Solutions Design Exam for Technology Architects Sample Questions:
1. Refer to the exhibit.
A customer has a Symmetrix VMAX storage array configured with FAST VP using three storage tiers. Policies are active for all storage groups on the array. The customer would like to increase the size of data movement requests. The current configuration of FAST is shown in the exhibit.
Which parameter should be changed?
A) Max Simultaneous Moves
B) Data Relocation Rate
C) Max Moves per Day
D) Data Movement Mode
2. How many buffer to buffer credits does a Symmetrix VMAX SRDF Fibre Channel port have?
A) 12
B) 7
C) 20
D) 4
3. You are designing an SRDF/S over Fibre Channel solution. Data centers are 50 kilometers apart. 4 Gb/s FC links are in place. How many buffer to buffer credits would you recommend in order to maximize the utilization of the links?
A) 25
B) 300
C) 100
D) 50
4. Refer to the exhibit.
You have used BCSD to model an SRDF/A solution. Based on the SRDF/A risk analysis shown what are your recommendations?
A) Ensure that the SRDF devices on the source and target arrays use the same protection and reside on disks with the same RPM. Provide more remote adapters.
B) Provide more bandwidth. Upgrade both arrays to Symmetrix VMAX.
C) Ensure that the SRDF devices on the source and target arrays use the same protection and reside on disks with the same RPM. Upgrade both arrays to Symmetrix VMAX.
D) Provide more bandwidth and more remote adapters. Upgrade both arrays to Symmetrix VMAX.
5. A customer plans to configure their new Symmetrix VMAX 20K. They want your advice on how to configure a storage pool. This new storage pool will handle random write I/O
What should be your advice about RAID types as they relate to performance?
A) Use RAID 1 because RAID 5 and RAID 6 will have a higher write penalty.
B) RAID type does not matter since everything in the VMAX goes through cache.
C) Use RAID 5 because it can be more efficient for random writes than RAID 1.
D) Use RAID 6 because both RAID 1 and RAID 5 have a higher write penalty.
