What could prevent VDA machines from registering in Citrix Cloud during migration?

• A. The VDA master image was NOT updated to communicate with the Cloud Connectors.
• B. One of the two Cloud Connectors is down and unresponsive.
• C. The Citrix policies have NOT been migrated to Citrix Cloud.
• D. The VDA on the master image has NOT been updated to a later version.

Answer: (A)

VDA registration to Citrix Cloud relies on the VDA agents knowing where to contact for registration. When VDAs are created from a master image during migration, that image must be prepared with the Cloud Connector information so the agents can reach Citrix Cloud and register. If the master image was NOT updated to communicate with the Cloud Connectors, the VDAs have no destination to register to, so they won’t appear in Citrix Cloud regardless of other conditions.

If a Cloud Connector is down, registration can fail only if there is no working connector available; in a typical two-connector setup, one being down doesn’t automatically prevent registration, because the other can handle it. Policies being migrated is not required for the initial registration, since registration happens before policy application. Updating the VDA to a newer version helps compatibility but isn’t the direct cause of being unable to register when the image isn’t configured to contact the Cloud Connectors in the first place.
