Which statement accurately describes the benefit of the policy-managed database feature with
Oracle KAL 12cR1?

A.
It protects against cascade failures due to network usage. It migrates workload isolation to
specific pools. Less important workloads shut down immediately.

B.
It protects against cascade failures due to load. It ensures that workload isolation is balanced
between pools. Less important workloads start transactionally.

C.
It protects against cascade failures due to load. It ensures workload isolation between pools. Less
important workloads shut down transactionally.

D.
It protects against cascade failures due to load. It ensures workload isolation between pools. Less
important workloads shut down and start uniformly.

E.
It protects against cascade failures due to load. It ensures workloads are not isolated between
pools. Less important workloads shut down transactionally.
