All server pools in a cluster are controlled by the policy set, when user-defined policy management is used.

A server pool can have different attributes defined for different policies in the policy set, when user-defined policy management is used.

A server pool can have the same attributes defined for different policies in the policy set, when user-defined policy management is used.
