. One set of advice suggests increasing the maximum connection pool size for db2datasource.
. The other suggests reducing the maximum connection pool size for db2datasource.
How should the administrator configure the data sources before reusing the Performance and Diagnostic Advisor?
A. Create a data source of the same name under cell scope.
B. Create a data source of the same name under server scope for each server.
C. Increase the minimum connection pool size for the data source.
D. Decrease the maximum connection pool size for the data source.
Answer: B
