A customer is migrating their SQL server from a NAS back end to a new RAID 1-protected Symmetrix
V-Max SE array. Perfmon was used to create a log view of an average day's activity against the database
LUN as represented in the exhibit. Unfortunately the database's data file and transaction log are located
on the same LUN. The database administrator has informed you that this database typically processes 25
GB worth of transactions over the course of their 12-hour business day.
Which discount in IOPS should be taken before determining the number of spindles required for the data
file LUN?
A.75

NO.5 A customer is running Concurrent SRDF/Star. The disaster recovery (DR) plan allows for the workload
to be switched to either the synchronous site or the asynchronous site. In addition, part of their DR plan is
to enable SRDF/Star protection once the workload site comes back online.
Which advice should be given to the customer?
A.If production fails over to the synchronous site, it is possible to run in a Star-protected configuration after
the return of the original workload site.
B.If production fails over to either the asynchronous site or synchronous site, it is not possible to run in a
Star-protected configuration from either site after the return of the original workload site.
C.If production fails over to either the asynchronous site or synchronous site, it is possible to run in a
Star-protected configuration from either site after the return of the original workload site.
D.If production fails over to the asynchronous site, it is possible to run in a Star-protected configuration
after the return of the original workload site.
