Which three statements are true about a job chain?
The correct answer is A. It can contain a nested chain of jobs. B. It can be used to implement dependency-based scheduling. E. It can be executed using event-based or time-based schedules. Oracle Scheduler job chains support nested chains, dependency-based scheduling, and both event-based and time-based execution triggers.

Why each option
Oracle Scheduler job chains support nested chains, dependency-based scheduling, and both event-based and time-based execution triggers.
A job chain can reference another chain as a step, allowing nested chains to model complex workflows with sub-dependencies.
Job chains are specifically designed to link steps with conditional logic and dependencies, so one step only runs after a prior step completes with a defined outcome.
Oracle Scheduler does allow the same program or nested chain to appear in multiple steps within a single chain, so this restriction does not exist.
A job chain step can have multiple dependencies on other steps using AND or OR conditions, so the one-dependency limit is incorrect.
A job chain can be attached to a schedule or event so it fires either at a scheduled time or in response to a system or user-defined event.
