• Question 65:

  What is an advantage of using thin provisioning?

  A. When the provisioning volume also protected with SRDF, no mirror positions would be used.

  B. Thin provisioning presents an application with more capacity than is physically allocated.

  C. Symmetrix Optimizer automatically tunes, monitors, analyzers, and migrate thin volumes to maintain optimal performance.
