Which two components must always be defined or specified by an administrator to make an application highly
available using Oracle 12c Clusterware?

A.
A Server Pool

B.
an application VIP

C.
an application resource

D.
a resource dependency definition

E.
a script agent

Explanation:
Oracle Clusterware manages applications when they are registered as resources with Oracle Clusterware.
Oracle Clusterware has access to application-specific primitives that have the ability to start, stop, and monitor
a specific resource. Oracle Clusterware runs all resource-specific commands through an entity called an agent.
Note: When initializing the agent framework, if any of the mandatory entry points are not provided, then the
agent framework invokes a script pointed to by the ACTION_SCRIPT resource attribute.
