EMC Symmetrix Solutions Design Exam for Technology Architects Sample Questions:
Question 1
What can happen if an over-subscribed thin pool becomes full?
A. writes to unallocated extents on TDEV's continue within cache and the virtual pool is not automatically expanded to the needed level.
B. writes to unallocated extents on TDEV's stay in a queued state until the storage administrator can assign additional capacity.
C. writes to unallocated extents on TDEV's continue within cache and the virtual pool is automatically expanded to the needed level.
D. writes to unallocated extents on TDEV's fail and an I/O error is returned. If the host is booting from SAN, this may also result in a server hang condition.
Question 2
You have been working with a customer on a new SRDF/A design and need to validate the configuration using Symmetrix data. Which tool do you use?
A. SymmMerge
B. E-lab Advisor
C. Tier Advisor
D. Analyzer Helper
Question 3
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. FAST VP Data Movement Mode
B. Min Initial Workload Period
C. Data Movement Mode
D. Workload Analysis Period
Question 4
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 of the databases during the 8-hour business day, Monday through Friday as shown in the exhibit. During an average business day, the transaction log processes 43 GB worth of data.
Following EMC best practices, which discount can be taken from the overall write IOPS when calculating for the database writes?
A. 597
B. 392
C. 989
D. 196
Question 5
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. Upgrade both arrays to Symmetrix VMAX.
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. Provide more remote adapters.
D. Provide more bandwidth and more remote adapters. Upgrade both arrays to Symmetrix VMAX.
