Question 61

Scenario: A Citrix Architect is designing a multi-data center Citrix Virtual Apps and Desktops environment that will use Citrix Provisioning (PVS) to manage Virtual

Delivery Agent (VDA) machine images. Each data center will have a separate PVS farm. During design discussions, the architect created a diagram to depict the way in which vDisk files will be replicated among PVS farms, based on the available storage for the vDisk stores.

Click the Exhibit button to view the diagram.

Overall, the customer has identified 3 objectives for the image-replication process:

✑ Administrative time required to replicate images among farms must be minimized.

✑ The process must be usable by storage administrators without PVS farm administrative permissions.

✑ Pre-existing infrastructure and processes should be used where possible.

Which method should the architect use to replicate vDisk files among data centers?

    Correct Answer: C

    In this scenario, the customer needs to replicate vDisk files among data centers with minimal administrative time, allow storage administrators without PVS farm administrative permissions to manage the process, and use pre-existing infrastructure. SAN replication is the best method to achieve these objectives as it automates the replication process at the storage level. This minimizes administrative effort, does not require specific PVS administrative permissions, and utilizes existing SAN infrastructure. Therefore, SAN replication is the optimal choice to meet all the customer's objectives.

Discussion
certhunterfembotOption: C

SAN Replication looks to be the best. "vDisks and Storage – For vDisk stores hosted on local, Direct Attached Storage (DAS) or Storage Area Network (SAN), replication should be used to synchronize the vDisks. If using Network Attached Storage (NAS), ensure that the vDisks are hosted on a highly available network share." https://docs.citrix.com/en-us/xenapp-and-xendesktop/7-15-ltsr/citrix-vdi-best-practices/design/design-userlayer4.html

C. SAN replication

keplerOption: C

both have SAN storages. Obviously native SAN replication works the best in this scenario.
