Hi @Kaustav ,
The certification that you have linked is retired, as you can see from the 70-703 exam page over here:
https://www.microsoft.com/en-us/learning/exam-70-703.aspx
The new certifications for SCCM / MECM will be par tof the Microsoft 365 certifications which you will find over here:
https://video2.skills-academy.com/en-us/learn/certifications/browse/?products=m365
Also note that Microsoft Certification is currently not supported in the Q&A forums, the supported products are listed over here https://video2.skills-academy.com/en-us/answers/products (more to be added later on).
You can ask more frm the experts in the dedicated Microsoft Certification forum over here:
