Which term describes a task that enforces precedence relationships in a workflow?

• A. Parallel Task
• B. Leaf Task
• C. Sink Task
• D. Upstream Task

Answer: (D)

In workflows, precedence is about which steps must happen before others. An upstream task is the one that appears earlier in the flow and sets the required order, effectively enforcing the sequence by something downstream cannot start until it completes. This makes it the best fit for describing a task that enforces precedence relationships. A parallel task is designed for concurrent execution, so it doesn’t enforce a strict order. A leaf or sink task represents an end point with no outgoing dependencies, not the enforcement of sequence.
