There are different levels of certification, and different technology tracks too - the training that is either recommended or required depends on which certification you want to achieve.
In terms of levels, there are 4:
Advanced Professional: VCAP
Design Expert: VCDX
There are numerous technology tracks, each of which has training on the relevant products:
Data Center Virtualization (VCP/VCAP/VCDX) - vSphere training
Network Virtualization (VCP/VCAP/VCDX) - NSX training
Cloud Management & Automation (VCP/VCAP/VCDX) - vRealize training
Desktop & Mobility (VCP/VCAP/VCDX) - Horizon training
Digital Workspace (VCP) - Workspace ONE training
There are also "digital badges" - these are certifications for those technologies that don't have full VCP/VCAP/VCDX options.
The best thing for you to do is as per the reply above - head to the Certification page, and browse the certifications and badges.
Thanks for your detailed replay !!! Are these online trainings are available in coursera ? I am more interested in coursera training for these certifications.
I'd not heard of Coursera til just now.
There is no authorised VMware training on that platform - VMware have their own online training options, many of the courses which meet the training requirement for VCP are available in an on-demand format, plus there's VMware Learning Zone (a subscription-based service)
