Question 8
Domain 1: Design ApplicationsA developer needs to configure a chain so that data is passed into a model and a result is returned from it. Which chain components should the developer choose to match the desired model input and output?
Correct answer: A
Explanation
Choose chain components based on the data a model must receive and the result it must produce. The input side should align to the model input, and the output side should align to the model output. — official.txt
Why each option is right or wrong
A. Components selected to match the required model input and the expected model output
The stated objective is to select chain components for a desired model input and output, so the correct choice is the one that aligns components with both what the model receives and what it returns.
B. Components selected only for the expected model output, regardless of model input needs
Chain components must be chosen for both model input and model output, not output alone.
C. Components selected only for the required model input, regardless of model output needs
Chain components must be chosen for both model input and model output, not input alone.
D. Components selected independently of the model input and output requirements
Selection is based on the desired model input and output requirements.
