Let me start by saying they didn't make sense to me when they asked them.1. Where do VAS mapping files exist? are they stored physically in AD?2. What version of LIB C is required for VAS client?3. Do group policy cron jobs get a kerb ticket?4. Is group policy top down or bottom up enforcement?5. When using mappings what, if any kerberos ticket do they get?6. Can VAS work if DNS reverse lookup is disabled?6. Can all group policies be managed from the command line?
