2. 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/
B) TimeFinder/Mirror and SRDF/S.
C) TimeFinder/Clone and SRDF/S.
D) TimeFinder/Clone and SRDF/DM.

3. A customer has implemented an Oracle application on a Symmetrix VMAX with a mix of Enterprise Flash Drives (EFD) and FC 15K drives. EFD are configured in RAID 5, and FC 15K drives are configured both in RAID 5 and RAID 1. In terms of IOPS activity, reads are predominant over writes. The customer decided to place a portion of the database in each tier.
Which Oracle database object(s) is suitable for placing on the FC 15K RAID 1 drives?

A) Data files
B) Index files
C) Temp file
D) Redo log files

4. A customer needs to configure SRDF/S between two sites 10 km apart. The customer
connected the R1 ports to fabric-A at site 1 and the R2 ports to fabric-B at site 2. The customer does not want to merge the two fabrics between sites.
What is the recommended solution?

A) Implement FCIP connection to isolate the fabric
B) Connect the RDF ports using DWDM or SONET.
C) Implement FC routing or Virtual SAN to isolate the fabric
D) Merge two fabrics, and zone R1 and R2 ports.

5. 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 can run in parallel and response time is slightly improved.
C) Writes need to be finished before new writes arrive and negatively impacts response time.
D) Concurrent SRDF/S writes will not help to improve response time.
