What would happen if the SQL Server in the primary datacenter were turned off?

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 datacenter for all users.

The following has been configured:

– NetScaler Global Server Load Balancing (GSLB) to provide single URL direction to the active datacenter.

– GSLB has health monitors configured for the load balanced servers.

– NetScaler Gateways are on both datacenters.

– NetScaler load balancing occurs for StoreFront and Delivery Controller XML services.

– A single XenApp and XenDesktop Site exists.

– Four Delivery Controllers are members of the Site.

– Two Delivery Controllers are members of the primary zone in the active datacenter.

– Two Delivery Controllers are members of the satellite zone in the passive datacenter.

– SQL is deployed in the active datacenter.

– Local Host Cache is enabled.

– Two StoreFront servers are deployed in each datacenter aggregating resources from the Delivery Controllers in the respective datacenter.

– Virtual Delivery Agent (VDA) machines are deployed in both datacenters and configured to register with Delivery Controllers in their zone.

What would happen if the SQL Server in the primary datacenter were turned off?
A . VDA machines from the primary datacenter would register with the Delivery Controllers in the passive datacenter.
B . GSLB will NOT identify that the SQL Server is down and sessions cannot launch.
C . StoreFront in the primary datacenter would still be able to launch sessions.
D . GSLB will start redirecting connections to the secondary datacenter.
