Scenario: A Citrix Engineer is managing a large environment with multiple locations. The setup is as follows: - The setup has a single Citrix Virtual…

The scenario describes a strict sovereign mandate requiring an application ('app1') to run exclusively in the same zone as its database (Satellite zone 1). The application cannot function without its database, and access from other zones is forbidden. The "Mandatory application home" setting is the only option that enforces this requirement. It ensures that 'app1' will only launch on a VDA in Satellite zone 1. If no resources are available in that specific zone, the launch will fail, which is explicitly stated as an acceptable outcome to comply with the mandate. This prevents any possibility of the application session running in another zone and attempting to access the database, thus violating the mandate.

B. User home to Satellite zone 1: This is a user-based preference, not an application-specific mandate. It does not prevent the user's session from launching in another zone if resources in zone 1 are unavailable.
C. Mandatory user home to Satellite zone 1: This is too restrictive and misaligned with the goal. It forces all of the user's sessions into zone 1, regardless of the application, which is inefficient for other apps. The requirement is specific to 'app1'.
D. Application home to Satellite zone 1: This is a preference, not a mandatory requirement. If VDAs in Satellite zone 1 are unavailable, the broker will attempt to launch the application in another zone, which would violate the sovereign mandate.

1. Citrix Virtual Apps and Desktops Product Documentation - Zones:

Reference: In the "Zone preference" section, the documentation distinguishes between a standard "application home" and a "mandatory" one. It states, "You can make an application home mandatory by selecting the Mandatory check box. If a mandatory application home is configured, the application launches only in that zone. In this case, the application launch fails if the zone is not available." This directly supports the use of a mandatory setting to enforce a strict location requirement.

2. Citrix Tech Zone - Citrix Virtual Apps and Desktops with Multiple Locations:

Reference: This reference architecture guide explains that zone preferences are designed to keep users, their sessions, and their data in the same location. For data sovereignty requirements where data must not cross geographical boundaries, a mandatory home zone for the application is the appropriate control to prevent session launch in non-compliant zones.
