• B.5.4:1
• C.5.3:1
• D.3.2:1

What accurately describes a use case for Database/Analytic environments?

• A.Low, small block random I/O activity.
  Application environments that tolerate high response times.
• B.High, large block sequential I/O activity.
  Application environments that require very low and consistent response times.
• C.High, small block random I/O activity.
  Application environments that require very low and consistent response times.
• D.Low, small block sequential I/O activity.
  Application environments that requires very low and consistent response times.

An XtremIO storage array reports an overall efficiency of 10:1. Which combination of Deduplication Ratio (DR), Compression Ratio (C), and Thin Provisioning Saving (TPS) would achieve this efficiency?

• A.DR = 5.0:1; CR = 1.0:1; TPS = 80%
• B.DR = 2.5:1; CR = 2.0:1; TPS = 20%
• C.DR = 2.5:1; CR = 2.0:1; TPS = 50%
• D.DR = 5.0:1; CR = 1.0:1; TPS = 33%
