Answer: D

Explanation:

vRealize Operations continuous availability (CA) separates the vRealize Operations cluster into two fault domains, stretching across vSphere clusters, and protects the analytics cluster against the loss of an entire fault domain. A fault domain consists of one or more analytics nodes grouped according to their physical location in the data center. To activate CA, you must have at least one data node deployed, in addition to the primary node and the witness node. The primary node and the data node must reside in different fault domains, and the witness node must reside in a third location. Therefore, the minimum number of fault domains required to achieve vRealize Operations continuous availability with a primary node, data node, and witness node is two.
