While using Citrix Studio to create a new Delivery Group, a Citrix Administrator does NOT see any machine catalogs listed, but does see an error message. Which issue can cause this to happen?

• A. The Virtual Delivery Agent (VDA) version is lower than 7.15 LTSR.
• B. There are no unassigned machine catalog machines.
• C. No machine catalog machines have been started.
• D. The administrator has insufficient permissions to create the Delivery Group.

Answer: (B)

Delivery Groups pull from machine catalogs that contain machines available for assignment. When you start the Delivery Group wizard, Citrix Studio shows catalogs only if there are machines in those catalogs that aren’t already allocated to another Delivery Group. If every machine in every catalog is already assigned, there are no eligible machines to include in the new group, so the catalogs don’t appear and an error is shown. In this scenario, the issue is that there are no unassigned machines in the catalogs. Freeing up machines (unassigning them from existing groups, powering them on, or adding more machines to a catalog) lets the catalogs populate again and allows you to create the Delivery Group. Other potential problems, like an incompatible VDA version, powered-off machines, or insufficient permissions, would present different symptoms and wouldn’t typically cause the catalogs to be invisible.
