• A.Nothing. Promotions on the source do not affect the target
• B.The corresponding extent on the R2 device will be promoted simultaneously only if the FAST VP policy allows it
• C.The corresponding extent on the R2 device will be promoted if the target Symmetrix is not too busy
• D.The corresponding extent on the R2 device will be promoted as long as there is storage space available in the higher tier

• C.Added volumes to an ASM instance would rebalance all existing Oracle objects automatically.

What is the impact on response time when multiple concurrent writes to an RDF device arrive from different FA ports on a Symmetrix VMAX?

• A.Response time is mostly determined by the application write behavior.
• B.Writes need to be finished before new writes arrive and negatively impacts response time.
• C.Concurrent SRDF/S writes will not help to improve response time.
