Hi Pradip,

I'm not exactly sure where you obtained these questions and why you're looking for the answers on this forum, but I would recommend to download the 'Exam details' file for the Reactive Developer certification from https://www.outsystems.com/certifications/. It contains a Detail Sheet, listing all the study materials that you should need to answer these and any exam questions.

It looks like you're trying to find quick answers for your exam, but honestly, the best way to learn and pass is by doing these exercises in Service Studio yourself. Using forum answers might help you now, but understanding the work hands-on will benefit you way more in the long run. Plus, some of the answers you've marked are correct, so you're on the right track! Just give it a try, and you'll see it's worth the effort.

These are the few sample questions i got from the various sites, and forums. I posted here because i did not find the answers. I have also sample file which is available on the certification page, few answers i got.
