The Global Server Load Balancing (GSLB) feature provided by Citrix ADC is designed to detect when a server or data center is unavailable and automatically failover to a secondary data center. In this scenario, since GSLB has health monitors configured for the load-balanced servers, it will detect that the Delivery Controllers in the primary data center are down. As a result, GSLB will redirect connections to the secondary data center, ensuring continuous availability and avoiding service interruption. Thus, GSLB will start redirecting connections to the secondary data center.
To meet the business requirement of having automatic update functionality disabled and deploying software exclusively via electronic software distribution (ESD), the Citrix Workspace Updates settings must be configured accordingly. The correct command line interface parameter to disable automatic updates when installing Citrix Workspace app for Windows is /AutoUpdateCheck=disabled.
To meet the requirements of accessing the environment in a single data center, performing maintenance without requiring an outage, and keeping management efforts to a minimum, the appropriate hardware requirement is N+1 Citrix Hypervisor hosts in a single cluster/pool. This setup provides redundancy (N+1) allowing for maintenance activities without downtime and simplifies management by using a single cluster within the data center.
To produce a report of all unsuccessful connections for Citrix Virtual Apps, the architect needs to configure the 'GroomFailuresRetentionDays' to 365 days to store failure logs for the desired period. Additionally, upgrading to Citrix Virtual Desktops Premium licenses is necessary as Advanced licenses limit the data retention to 31 days, whereas the Premium licenses allow longer retention periods required for the 12-month report.
The Microsoft Hyper-V Server 2012 R2 must be changed. NVIDIA virtualized GPUs, such as the NVIDIA GRID Tesla P40, require a minimum of Windows Server 2016 with the Hyper-V role to function properly. Hyper-V Server 2012 R2 does not support these virtualized GPU configurations, and thus it is the component that does not meet the requirements for the Citrix Virtual Desktops environment utilizing shared virtualized GPUs.
