Which two statements about server pools are correct?

A.
Server pools logically apportion a cluster into groups of servers offering database or application
services.

B.

C.

D.

Explanation:
Server pools logically apportion a cluster into groups of servers offering database or application
services. Server pool properties control the scalability and availability of those databases and
applications. You can configure each server pool with a minimum and maximum size, which
determines scalability. Oracle Clusterware manages availability between server pools, and you can
further regulate availability by configuring the importance value of individual server pools.
