EMC Symmetrix Solutions Design Exam for Technology Architects Sample Questions:

1. Which action is part of the analysis and design of a synchronous data protection solution for a Symmetrix VMAX implementation?

A) Use Change Tracker to determine the bandwidth required from the DELTA data set for a given interval.
B) Use STP Navigator to examine the BTP data and determine if the data is valid for further analysis.
C) Use Symmetrix Performance Analyzer to determine the peak data requirement based on STP data collected from the source array for a 24 hour sample period.
D) Use Performance Analyzer and EMC Control Center repository data to determine the peak data period and bandwidth required.

2. A customer is trying to perform an SRDF/A Consistent Mode Change. The change rejected repeatedly by the secondary array. What could cause this condition?

A) The 70% cache write pending limit on the primary array is reached
B) Enginuity versions on both arrays are below 5875
C) More than 50% of the SRDF/A write cache on the R2 site is in use
D) SRDF/A MSC is not configured

3. 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 "N:\". You have decided on RAID-5 protected 15,000 RPM drives for the new SQL database and RAID-1 for the transaction log.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.

A) Provide more bandwidth. Upgrade both arrays to Symmetrix VMAX.
B) 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.
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.

5. Exhibit:

You have used BCSD to model an SRDF/A solution and have an SRDF/A risk analysis, as shown in the exhibit. What should be your recommendation?

B) Provide more bandwidth. Upgrade both arrays to Symmetrix VMAX.
C) Ensure that the RDF devices use the same RAID and drive configuration. Provide more remote adapters.
D) Provide more bandwidth and more remote adapters. Ensure that the local and remote arrays run the same Enginuity level.
