Exam 1Y0-403 topic 1 question 94 discussion

Scenario: A Citrix Architect is designing a new Citrix Virtual Apps and Desktops environment. Currently, the environment is configured as 2 locations with identical
Citrix Virtual Desktops Sites. Each Site has 2 Delivery Controllers, 2 StoreFront servers, and 1 Citrix ADC high-availability pair. The same applications have been published from both Sites for all users. Two zones (Zone A and Zone B) are configured in each Site with 1 Delivery Controller in each zone. The Microsoft
Exchange server is only accessible from Virtual Delivery Agent (VDA) machines in Zone A in each Site.
Six access requirements have been identified:
✑ Users should have a single URL when accessing resources from different Sites.
✑ Users should always connect to the data center closest to their location.
✑ Applications added to Favorites within the Citrix Workspace app should be retained when accessed from different Sites.
✑ Launched applications and desktops should always connect through a local Citrix ADC.
✑ No duplication of applications published from different Sites.
✑ Microsoft Outlook should always launch in Zone A.
What should the architect recommend configuring to avoid duplication of the same applications being delivered from different Sites?
