B. Set trigger through Advanced Run options: Advanced Run options are used to control a single, specific execution of a task, such as starting from a particular timestamp, not for creating a recurring schedule.
C. Set trigger through Task Designer: The Task Designer is where the task's components (endpoints, table selection, transformations) are defined, but it does not contain settings for scheduling execution.
D. Enable task on full load and apply changes: This describes the manual process of starting a one-time full load. It is not an automated or recurring process.
