Question 47

Scenario: A Citrix Engineering maintains a multi-zone XenDesktop infrastructure with two Virtual Delivery Agent (VDA) machines located in the Primary Zone and two VDAs in the Satellite Zone. Each zone contains a single Delivery Controller.

During an unexpected outage, the Delivery Controller in the Satellite Zone went offline and did NOT resume.

What will happen to the two VDAs in the Satellite Zone?

Both VDAs in the Satellite Zone will go to an unregistered state and NOT attempt to re-register until the local Delivery Controller resumes and is online.

Both VDAs in the Satellite Zone will immediately attempt to register with the Delivery Controller in the Primary Zone.

Both VDAs in the Satellite Zone will remain in a registered state, even when the Delivery Controller is offline.

Correct Answer: A

Both VDAs in the Satellite Zone will make intermittent attempts to re-register with the Delivery Controller in the Satellite Zone and then attempt to register with the Delivery Controller in the Primary Zone. This behavior aligns with how VDAs are designed to attempt to reconnect to their original Delivery Controller first before looking for alternatives, ensuring that they do not immediately switch to backup controllers unless necessary.

Discussion

AcademOption: C

C looks correct. ” If no local Controllers are available (for example, because the local Controllers cannot accept more VDA registrations or the local Controllers have failed), the VDA will attempt to register with a Controller in the primary zone”
