The company is implementing XenDesktop globally for desktop virtualization. How should the architect recommend installment of controllers for high availability?
The correct answer is B. Install one controller in New York and one in Hong Kong. For a global XenDesktop implementation, placing controllers in geographically diverse locations like New York and Hong Kong offers robust high availability and disaster recovery.

Why each option
For a global XenDesktop implementation, placing controllers in geographically diverse locations like New York and Hong Kong offers robust high availability and disaster recovery.
London and Paris are geographically proximate, offering limited protection against wide-area regional outages compared to intercontinental distribution.
Distributing the minimum two Delivery Controllers across widely separated continents, such as New York and Hong Kong, provides global disaster recovery capabilities. This strategy ensures service continuity even if an entire region or data center experiences a catastrophic outage, addressing the 'globally' requirement.
Hong Kong and Tokyo are geographically proximate within Asia, providing insufficient global disaster recovery capabilities.
While New York and London offer intercontinental separation, New York and Hong Kong provide an even greater global spread, which is often preferred for comprehensive 'global' high availability scenarios.
