What is the purpose of parameter exposure in a custom transformer regarding input attributes?

• A. All input attributes are automatically exposed.
• B. You can manually control exposure of inputs.
• C. Parameters must be numerical.
• D. Exposure is mandatory for every input.

Answer: (B)

Exposure of input attributes in a custom transformer lets you choose which inputs are surfaced to users as configurable parameters. This gives you control over the transformer’s user interface and behavior: you can surface only the attributes that matter for the workflow, rename or alias them for clarity, and drive logic or mappings without editing the transformer each time. That’s why the best answer is that you can manually control exposure of inputs.

Remember that not all attributes must be exposed (so it isn’t automatic), parameters aren’t limited to numbers, and exposure isn’t mandatory for every input.
