問題 #1

Which one of the following options is CORRECT about DB2 pureScale feature?

A. DB2 pureScale uses the same concept of HADR where the data is replicated from a primary database to a standby database.
B. DB2 pureScale is only available for DB2 Express-C and DB2 Advanced Enterprise Edition.
C. DB2 pureScale persists data in the cluster caching facilities (CFs).
D. DB2 pureScale reduces the risk and cost associated with growing your distributed database solution by providing extreme capacity and application transparency.

問題 #2

Which of the following options best describes the differences between Label Based Access Control (LBAC) and Row and Column Access Control (RCAC)?

A. RCAC is a fixed label security model designed for the US government while LBAC is a general purpose security model best suited for commercial customers.
