Scenario: A Citrix Architect has designed an active/passive XenApp and XenDesktop environment for a customer, where the passive datacenter serves as the disaster recovery (DR) datacenter for all users.
The following has been configured:
NetScaler Gateways in both datacenters, each with a unique URL
NetScaler load balancing of StoreFront and Delivery Controller XML services
A separate XenApp and XenDesktop Site at each datacenter
Two StoreFront servers deployed in each datacenter aggregating resources from the Delivery Controllers in the respective datacenter
During a disaster recovery strategy review, the IT infrastructure director recommends exploring cloud-based disaster recovery options for the XenApp and XenDesktop environment. The director reminds the team that the new solution would also have to support the following objectives:
The DR environment needs to be fully functional in the event that the primary datacenter goes completely offline.
The DR environment should require minimal operating costs until it is needed to host active user sessions.
In a DR event, active user sessions should connect directly to the resource location without going through additional hops.
The architect develops four different conceptual diagrams to display the current architecture as well as the potential cloud-based DR locations.
Click the Exhibit button to view the conceptual diagrams.
Based on the diagrams and above requirements, which Site architecture should the architect use?
A. Option 4
B. Option 2
C. Option 3
D. Option 1
