Which of the following statements describes a parameter requirement for a task type that integrates with an external application?

• A. A parameter is required for a task that integrates with an external application and requires a year and month input.
• B. A parameter is optional for all tasks.
• C. A parameter is required for every task regardless of type.
• D. No parameter is ever required.

Answer: (A)

When a task talks to an external application, it must know the scope of what to process. If the external integration relies on a specific time period, you must supply a parameter that defines that period, typically a year and month, so the task targets the correct slice of data.

This is why the statement is the best fit: the integration task requires a year-and-month input to operate, making the parameter mandatory. Without that period context, the external operation wouldn’t know which data to fetch or apply, leading to ambiguity or errors. Other options are too broad or incorrect because not every task needs a parameter, and some tasks can run without external data or context.
