According to the VMware vRealize Operations Cloud Cost Management Guide1, cost drivers are the factors that influence the cost of running a service or a resource. Cost drivers can be based on various parameters, such as hardware, software, labor, power, cooling, etc. Cost drivers can be configured in vRealize Operations to reflect the actual costs of the monitored environment and to generate accurate cost reports and analysis.

One of the types of cost drivers that can be configured in vRealize Operations is Server Hardware. This cost driver allows the administrator to specify the purchase price and date of the physical servers that host the virtual machines. The purchase price and date are used to calculate the depreciation and the residual value of the servers over time. The Server Hardware cost driver has three sub-types: Traditional, Hyper-Converged, and Cloud. Each sub-type has different options and calculations for the cost driver.

The Traditional sub-type is used for servers that have separate storage devices, such as SAN or NAS. The Hyper-Converged sub-type is used for servers that have integrated storage devices, such as vSAN. The Cloud sub-type is used for servers that are hosted by a cloud provider, such as AWS or Azure.

Therefore, the correct answer is A. Server Hardware: Hyper-Converged, as this is the type of cost driver that should be selected by the administrator to configure the cost of the nodes within the VMware vSAN cluster that are being monitored. References:
