VCDX is the highest level of certification offered by VMware, and is only awarded to those candidates who have demonstrated an elite level of solution design and implementation before a panel of VCDX accredited VMware experts. The VCDX Panelist is a critical component of this process, and a member of world-class consulting architects. After earning the VCDX themselves, VCDX Panelists must meet a high level of preparation and practice before judging candidates on a VCDX panel.
