• Question 117:

  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. During an average business day, the transaction log processes 87 GB worth of data.

  

  Following EMC best practices, what is the minimum number of spindles that must be allocated for optimal transaction log performance?

  A. 2
  B. 4
  C. 8
  D. 10
  B. 4

• Question 118:

  A customer is implementing a Microsoft Exchange environment on a Symmetrix VMAX. The environment will be deployed on 600 GB FC 15K drives using RAID 5 data protection. The application generates 2000 I/ O per second with an I/O pattern that is 75% reads and 25% writes. What is the minimum number of drives recommended to support the application?

  A. 12
  B. 18
  C. 24
  D. 32
  C. 24

• Question 119:

  Prior to starting an implementation, which tool should be used to automate the data collection on a UNIX host?

  A. EMCGrab
  B. EMCReports
  C. E-Lab Advisor
  D. Change Tracker
  A. EMCGrab

• Question 120:

  A Symmetrix VMAX has been configured with Dynamic Cache Partitions. What is a criterion that must be met for a cache slot to be eligible for donation?

  A. The fall through time must be greater than the donation age
  B. The fall through time must be less than the donation age
  C. The cache slot must belong to a static partition
  D. There must be available cache slots in the default partition
  A. The fall through time must be greater than the donation age
