Hi @SrihitaR Our FAQs state: 
What happens if I don’t pass the exam the first time?
You are welcome to reregister and retake the exam after 14 days. You can retake the exam as many times as you would like, but you have to wait 14 days between each take. Each attempt is charged at the same price as the original exam. Databricks will not issue free retake vouchers for any exam.
