Citrix Workspace – Planning and Building — Question 81

Scenario: A Citrix Architect needs to support a XenApp and XenDesktop environment with two datacenters. App Layering is being used to create Layered Images that are used by the Virtual Delivery Agent (VDA) machines in both datacenter locations. To comply with disaster recovery requirements, administrators must be able to modify and deploy Layered Images from either datacenter if needed.
Which statement correctly describes the process that the architect must follow to meet the requirements?

Answer options

• A. All required layers should be exported from the first Enterprise Layer Manager to an SMB file share, and then imported into the second Enterprise layer manager.
• B. All required layers should be copied from the first Enterprise Layer Manager to the second Enterprise Layer Manager using robocopy commands.
• C. All required layers should be copied from the first Enterprise Layer Manager to the second Enterprise Layer Manager using Microsoft DFS-R.
• D. All required layers should be exported from the first Layer Manager using the hypervisor hosting the machine, then imported to the hypervisor resource pool in the secondary datacenter.

Correct answer: C

Explanation

The correct answer is C because Microsoft DFS-R allows for efficient replication of the required layers between the two Enterprise Layer Managers, ensuring that both datacenters have access to the same Layered Images. Options A and B suggest methods that do not provide continuous synchronization, and option D involves exporting and importing layers manually, which is not as efficient or compliant with disaster recovery needs.
