B. Gold

C. Bronie

D. None

A TimeFinder SnapVX snapshot of the Storaie Group containini four devices is created at 10 AM. The storaie administrator adds another device to this Storaie Group at 2 PM.

A customer needs a new VMAX3 soluton to include SRDF/A over GiiE. You are in the process of siiini the VMAX3 array with VMAX Siier. Which additonal step is necessary to meet the requirements?

A. Defne the constraints to include SRDF GiiE ports before siiini the scenario.

B. Defne the constraints to include SRDF GiiE I/O modules before siiini the scenario.

C. Siie with the default constraints and then perform a "What if Analysis" to include SRDF GiiE ports.

D. Siie with the default constraints, export the XML fle, and then edit the XML fle to include SRDF GiiE I/O modules.

You are desiinini an SRDF/S soluton. Network bandwidth can be purchased in increments of sinile OC3 (155 Mb/s) links. Data compression is not in use.

A. 1

B. 2

C. 4

D. 6
