Which Vblock 300 option is recommended to enable fault isolation, eliminate resource overhead
and monitor performance?

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?

Refer to the exhibit.

A customer has a production data center (Site A) and a synchronous disaster recovery data center
(Site B). They recently purchased a third data center (Site C) 820 km away from the production
site. The customer now wants to implement SRDF/Star. In addition to licensing SRDF consistency
groups at Site A and SRDF/Star on all participating Symmetrix DMX-4, what minimal licensing is
required?
