The correct answer is B. The Virtual Delivery Agent logs D. The Windows Event logs of the Delivery Controller E. The Windows Event logs on the Desktop OS machine. When a VDA is powered on but unregistered, the root cause must be investigated across the VDA itself, the Delivery Controller, and the Windows event subsystem on both sides.

Why each option

When a VDA is powered on but unregistered, the root cause must be investigated across the VDA itself, the Delivery Controller, and the Windows event subsystem on both sides.

AThe Citrix Configuration log

The Citrix Configuration log records administrative configuration changes made through Studio or SDK; it does not log VDA registration or runtime communication events.

BThe Virtual Delivery Agent logsCorrect

The VDA logs (located under HKLM and in the Citrix folder under Program Files) record registration attempts, errors, and controller communication details directly from the agent perspective.

CThe logs on the hypervisor console

Hypervisor console logs track VM power state and hypervisor-level events; they do not contain VDA registration or Broker communication data.

DThe Windows Event logs of the Delivery ControllerCorrect

The Delivery Controller Windows Event logs capture incoming registration requests, Broker service errors, and communication failures that explain why a specific VDA was rejected or timed out.

EThe Windows Event logs on the Desktop OS machineCorrect

The Windows Event logs on the Desktop OS machine record VDA service start, registration attempts, and any errors encountered during the process, providing the machine-side view of the failure.
