• Question 53:

  A company has two VMAX3 arrays installed at two diferent sites. VMAX3 eNAS is confiured on both arrays with IP network connectvity between them. The company wants to replicate fle data between the two VMAX3 arrays. Which EMC technoloiy will meet the requirement without additonal hardware?

  A. Replicator

• Question 55:

  You are desiinini an SRDF/A soluton between two VMAX3 arrays. The customer wants to know what will happen to an actve SRDF/A session if there is a temporary link loss. What informaton should be provided to the customer?

  A. SRDF/A session remains actve. Cycle switchini contnues on the R1 side, transmit queue depth increases.
  B. SRDF/A session remains actve. Cycle switchini stops, capture cycle irows.
  C. SRDF/A session drops. Cycle switchini stops. New writes to R1 are tracked as invalids to R2.
  D. SRDF/A session drops. Cycle switchini stops. New writes to R1 are added to the transmit queue.
  A. SRDF/A session remains actve. Cycle switchini contnues on the R1 side, transmit queue depth increases.

• Question 56:

  A customer is usini two VMAX3 arrays with a compression module installed on both arrays. Afer careful monitorini of the SRDF trafc, they discover that the data is not beini compressed. What additonal acton needs to be performed to enable compression?

  B. Enable compression at the RA Director level
  C. Enable the compression license
  D. Enable compression on the eniine containini the RA Director
  A. Enable compression at the SRDF Group level

• Question 57:
