As per our exchange of messages on LinkedIn:
The NSX-T exams are on 2.4 and now 3.0 - I don't know what training or other certifications you have done but you need to make sure you meet ALL the requirements:
I would add here that the NSX-T 2.4 exam will retire long before the 3.0 exam, on that basis I would suggest focusing on 3.0.
The link above will expose exam guides for both NSX-T exams.
