Which two components must always be defined or specified by an administrator to make an application highly available using Oracle 92c Clusterware? (Choose two.)
A. an application VIP (Virtual IP):
Purpose: The application VIP provides a single, stable IP address that clients use to connect to the application, regardless of which node the application is currently running on.
High Availability Role: When a node fails, the VIP and the application resources associated with it are automatically failed over to another node in the cluster. Clients can continue to access the application using the same VIP, ensuring uninterrupted service.
D. an application resources:
Purpose: These are the components that Oracle Clusterware manages and monitors to ensure the application's availability. This could include the application's executables, configuration files, database instances, listener, etc.
High Availability Role: Oracle Clusterware monitors these resources. If a resource fails or a node fails, Clusterware will attempt to restart the resource or fail it over, along with the associated VIP, to another healthy node.
