• Question 184:

  A customer wants to protect production data using local and remote replication on a pair of VMAX arrays located 500 km apart. Both VMAX arrays are fully configured with virtually provisioned thin volumes.

  The customer has a Recovery Point Objective (RPO) of thirty minutes and wants to replicate the production volumes to the remote array while maintaining a separate backup copy on the local array. Which replication options do you recommend they implement?

  A. TimeFinder/Clone and SRDF/A.

  B. TimeFinder/Clone and SRDF/S.

  C. TimeFinder/Mirror and SRDF/A.

  D. TimeFinder/Snap and SRDF/S.

  Correct Answer: A

• Question 185:

  A customer wants to protect production data using local and remote replication on a pair of VMAX arrays located 100 km apart. Both VMAX arrays are fully configured with virtually provisioned thin volumes.

  The customer has a near zero Recovery Point Objective (RPO) and wants to replicate the production

  volumes to the remote array, while maintaining a separate backup copy of the production data on the local

  array.

  Which replication options do you recommend they implement?

  A. TimeFinder/Snap and SRDF/A.

  B. TimeFinder/Clone and SRDF/S.

  C. TimeFinder/Mirror and SRDF/S.

  D. TimeFinder/Clone and SRDF/DM.

  Correct Answer: B
