Network engineers and system administrators must demonstrate mastery of Citrix Provisioning Server 5.0 architecture, including the deployment of vDisks, implementation of stream-based target device booting, and configuration of PXE-enabled infrastructure. Candidates must execute end-to-end setups involving SQL database connectivity, Active Directory integration, and the management of write-cache files to ensure high availability for virtualized desktop environments. Mastery involves optimizing BIOS and NIC configurations, securing communication through DHCP and TFTP scopes, and performing complex maintenance tasks such as vDisk versioning, base image updates, and load balancing across server farms. Technical proficiency extends to troubleshooting stream service performance bottlenecks and multi-site replication.
