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 array has been in service for over 30 days.
When using Unisphere for VMAX to check, the customer notices no active ingress and egress of extents for the EFD tier. The current configuration of FAST is shown in the exhibit.
Which parameter should be changed?

A) Workload Analysis Period
B) Data Movement Mode
C) Min Initial Workload Period
D) FAST VP Data Movement Mode

2. You are designing the Symmetrix VMAX architecture for a DAS-to-SAN SQL Server migration. Currently all user databases reside on a single locally-attached disk enclosure, mounted to "M:\". You have decided on RAID-1 protected 15,000 RPM drives for the new SQL environment.

Last week, you configured Perfmon to record the current IOPS load as shown in the exhibit. Following EMC best practices, what is the minimum number of spindles required to satisfy the performance needs of the database?

A) 9
B) 18
C) 10
D) 20

3. What is the EMC recommended network quality for SRDF/S over GigE?

A) Less than 0.1% packet loss
B) Less than 0.01% packet loss
C) Less than 1% packet loss
D) Less than 0.25% packet loss

4. A customer has several internal organizational units with different requirements for their unique lines of business applications. Which approach provides the most predictable performance for each business unit on the array?

A) Segregate the BCV/Clones/Pools across the front end, back end, and engines, but only if the workloads demonstrate very low concurrence.
B) Segregate the BCV/Clones/Pools across the front end, back end, engines, and disk to optimize each workload on its allocation of system elements.
C) Evenly distribute the BCV/Clones/Pools across the front end, back end, engines, and disk to optimize use of all system resources.
D) Evenly distribute the BCV/Clones/Pools across the front end, back end, engines, and disk, but only if the workloads are highly concurrent so that all system resources can be optimized.

5. 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) Enable concurrent SRDF using SRDF/A from the BCV-R1.
B) Concurrent SRDF migration is not supported for this configuration.
C) Host level migration is the only migration option for this configuration.
D) Enable concurrent SRDF using SRDF/S from the BCV-R1.
