3. Event-Driven Architecture [OR_MUST]
4. Cloud Serverless Functions

[!NOTE]
Behavior Breakdown:
[OR_MUST]: The respondent must select at least one of the flagged options (Option 2 or Option 3*) to qualify for the study.
[EXCLUSIVE]: Selecting Option 5 ("None of the above")* automatically unchecks and locks out all other choices, preventing invalid multiple combinations. If you also want selecting "None of the above" to immediately screen out / disqualify the respondent, combine it with [CLOSE] (e.g., [FIX, EXCLUSIVE, CLOSE]).
