250-513 Question #8: Real Exam Question with Answer & Explanation

You administer storage for an application "myapp" on server QA1, with a file system dedicated to code and configuration data for that myapp. Part of the testing discipline is to return myapp's file system to a known initial state prior to each test activity, and to run a series of tests beginning with the same initial state. The traditional approach to preparing for each test involves restoring the file system from a backup image prior to each test, which imposes an hour's delay between the end of one test run and the beginning of the next. A typical testing session lasts only two to three hours, the hour of restore delay between tests reduces the availability of the server for testing by about 30%. What kind of Storage Foundation mechanism would work best to reduce the delay required between tests?
