    B. 12,800 kB

    C. 25,600 kB

  • Question 63:

    A customer has an environment consisting of 20 classic LUNs of 150 GB each that hold data from a custom application, and 5 thick LUNs of 500 GB each that are used for a database application. Free disk space on the system amounts to 500 GB.

    The customer runs a scan of the classic LUNs each night to check for data corruption. The application must be shut down in order to run the scan. Scans are taking too long to run, and production is affected. The customer asks for a solution to the problem.
