1Y0-205: Citrix Virtual Apps and Desktops 7 Administration

VDA registration requires reachable Controller communication paths, Kerberos authentication with clocks kept within the permitted skew, and a running VDA registration service. Misconfigured firewalls can block required traffic; time differences can invalidate Kerberos tickets; and a stopped Citrix ICA service (BrokerAgent/Citrix Desktop Service) prevents the VDA from registering.
