A,B and C are correct E is incorrect because itis about reverse DNS lookup zone record. In ListOfDDC registry or GPO setting you put DNS FQDN and DNS Forward lookup zone record is used to resolve the name to IP.

A, B and C are correct. A and B are self explanatory. C because the names of the delivery controllers can be specified in a GPO and if they are wrong, it will cause registration to fail. I am pretty sure reverse DNS lookups are not an issue.

That is what I believe as well. The ICA service would only affect the VDA from being able to use other published apps. There isn't a policy that would define the connection to the VDA.

But there is a Citrix policy (called "Controllers") where you specify List Of DDCs for VDA. Regardong answer "E" they mention reverse DNS lookup but VDA only needs to resolve DDC FQDN (if DDC is not specified by IP) however in blog pasted above they mention to ping DDC by FQDN from VDA and vice versa ping VDA from DDC by FQDN - means forward DNS lookup (not reverse)
