Question
Refer to the exhibit. A customer was running a database application whose data and logs were distributed across Symmetrix arrays S1 and S2. The data was being remotely replicated on Symmetrix arrays T1 and T2 using synchronous SRDF. A network outage caused the links between S1 and T1 to fail, while the application continued to run and data continued to be replicated from S2 to T2. A few hours later a disaster caused the entire source site to fail. When the customer tried to start up the applications at the remote site, the data on S2 and T2 were found to be unusable. Which SRDF technology would have prevented the problem? EMC E20-500 Exam
