    Which parameter should be changed?

    A. Data Relocation Rate

    B. Max Simultaneous Moves

    C. Max Moves per Day

    D. Data Movement Mode

  • Question 12:

    Refer to the exhibit.

    A. Moderate Skew

    B. Heavy Skew

    C. Low Skew

    D. Default Skew

  • Question 13:

    The SiRT feature is enabled on the RA in an SRDF/S configuration. When does the host receive the acknowledgement of a write?

    A. When I/O is written to the cache at the R2 site and acknowledgement is received by the R1 site from R2 site

    B. When I/O is written to R2 site cache but not acknowledged yet

    C. When I/O is written at R1 site cache and sent to the R2 site

    D. Immediately after the I/O is written to R1 cache

  • Question 14:

    C. Protection Bitmap

    D. Symmetrix Track Table

  • Question 15:

    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. Data Movement Mode

    C. Workload Analysis Period

    D. Min Initial Workload Period

  • Question 16:

    What is the most important advantage of implementing an ASM, Oracle 11g application on an existing Symmetrix array?

    A. Added volumes to an ASM instance would rebalance all existing Oracle objects automatically.

    B. Added new volumes to the ASM disk group will enable the DBA to issue an ASM rebalance command.

    C. Added volumes to the ASM disk group will automatically re-stripe the data across the target TimeFinder/Clone volumes.

    B. Oracle online redo logs and archive log files

    C. DSS database with high sequential write activity

    D. Database objects with pure sequential workload

  • Question 20:

    Prior to creating the Symmetrix VMAX architecture for Microsoft SQL, you are given a Perfmon Log view containing data for the database LUN. The file contains read and write IOPS collected over the past week, at 3-minute intervals.

    Which method should be used to determine the correct IOPS target for calculating the appropriate number of RAID corrected spindles?

    A. 90th percentile

    B. 75th percentile

    C. Overall Peak

    D. Overall Average
