Hi my organization is providing me online training from HP.
Course ID : H9P79S VMware vSphere 6 Fast Track.
I am handling vSphere5.5(ESXi 5.5, vcenter 5.5, vcenter heartbeat, update manager)
If i take this course for which certification will i qualify.
With my experience can i go for Data Center Virtualization?
If so DCV has VCA6-DCV, VCP6-DCV, will i qualify for these with this training
vSphere 6 Fast Track is one of the qualifying training courses for VCP6-DCV - look through Path 1 on this page: VCP6-DCV Certification
It sounds like it would make sense for you to follow the DCV certifications given your vSphere experience.
VCA6-DCV has no training requirement, but I wouldn't bother taking it and go straight to VCP level as above.
