On the left Side you have access to the Main Desktop , Vcenter Server Appliance , ESXi Hosts , Actve Directory Server , VUM , vSphere Replication Server .
In the Main Desktop you can access the vSphere Web Client and also vsphere viclient to connect to the ESXi Hosts .
Thanks for your response on my query, in that case we should be able to connect to vcenter server as well using vSphere viclient?
kindly please advise if it allow 30 minutes extra for no English countries as it is not mention in Blue print unlike from VCAP 550 blue print?
