Hi Sudheer
Welcome to Q&A Forum; this is a great place to get support, answers, and tips.
Thank you for posting your question; I'll be more than glad to help you out.
As Dave already stated...
You must take an exam and finish it successfully to earn a certification.
On some certifications, it is enough to run one exam (like AZ-104 - Azure Admin) or two exams to receive your certification (like AZ-304 - Azure Solution Arch.)
I hope my answer is helpful to you,
Your
Bjoern Peters
