What is one benefit of using the Controller service provider interface (SPI)?

  1. Modifications can be made directly to the navigation model.

  2. The Controller SPI can be used to make changes to any virtual portal that is running on the system from the base portal.

  3. Changes can be made and applied to a running portal environment. The portal does not need to be restarted for the changes to take effect.

  4. The modifications that are made come into effect immediately for the controller and are reflected in the persistence layer without committing the controller.

Answer: D Explanation: Explanation :

The Controller SPI provides controllers for portal resources. You can use these controllers to modify portal resources that are exposed by particular models of the Model SPI. Controllers offer methods to modify the topology and properties of the model and of its nodes. They expose the same interfaces as the corresponding read-only model, and they

instantly reflect modifications that you apply to the controller.

Note: While the modifications come into effect immediately for the controller, they not reflected in the persistence layer until you commit the controller and the changes that you made by it.
