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.

D. The provisioning will help meet service-level requirements while providing powerful local-replication Capabilities.

How does Enginuity Consistency Assist (ECA) differ from PowerPath?

A. ECA suspends I/O at the Symmetrix level; PowerPath suspends I/O at the host level.

B. ECA suspends I/O at the host level; PowerPath suspends I/O at the Symmetrix level.

C. ECA cannot suspend I/O for multiple hosts, but PowerPath can.

D. ECA supports TimeFinder/Clone only; PowerPath supports TimeFinder/Clone and TimeFinder/Snap.

What is the result if one or more source (R1) devices in an SRDF/S consistency group cannot propagate data to their corresponding target (R2) devices?

A. RDF daemon trips the con-group, thereby suspending data propagation from all R1 devices in the consistency group.

B. Target (R2) devices will be Read/Write enabled at the R2 site.

C. PowerPath suspends data propagation to the R1 devices in the consistency group (trip the con-group).

D. RDF daemon suspends the data propagation from the affected R1 devices while maintaining consistency among the remaining devices.
