Question #23
A VMAX3 system administrator needs to create a SRDF relationship for a planned data migration. Which replication mode of SRDF is recommended for the initial bulk data transfer?
- AAdaptive Copy Disk
- BSynchronous
- CAsynchronous
- DAdaptive Copy Write Pending
Correct Answer:
A
SRDF/Synchronous (SRDF/S), SRDF/Asynchronous (SRDF/A), and SRDF Adaptive Copy are the basic operation modes of SRDF. The first two are valid for
Oracle database protection and maintain dependent write-order consistency. The third is useful for bulk data transfers or in combination with more complex SRDF solutions such as SRDF/Automated Replication (SRDF/AR)
