I would at least start with VCIX before going for VCDX, especially not having that much experience with VMware. Go up the track, doing VCP > VCAP > VCIX and then you should be better prepared for VCDX.
Thanks , you are absolutely right , am already started to follow the same path.
But as per VMWARE certification map , we have only VCP>VCAP>VCDX paths. correct me if am wrong. ?
Yes, you are right. VCIX is actually an Accreditation that you get when you do both VCAP-Deploy and VCAP-Design.
