Data nodes are the type of node in a vRealize Operations (vROps) design that allow an administrator to scale out vROps to monitor very large environments. Data nodes are additional nodes that have all the vROps services installed, such as UI, Controller, Analytics, Collector, and Persistence. Data nodes perform data collection and analysis, and increase the capacity and performance of the vROps cluster. Data nodes can be added or removed as needed to adjust to the changing workload and environment size. Remote collectors are not a type of node in a vROps design, but a separate component that can be deployed to collect data from remote sources and send it to the vROps cluster. Remote collectors do not store data or perform analysis, and do not increase the capacity or performance of the vROps cluster. Replica Primary nodes and Primary nodes are not the type of node that allow an administrator to scale out vROps to monitor very large environments, but the type of node that provide high availability and continuous availability for the vROps cluster. Replica Primary nodes and Primary nodes contain critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. Replica Primary nodes and Primary nodes do not perform data collection and analysis, and do not increase the capacity or performance of the vROps cluster. References: About vRealize Operations Cluster Nodes, section “About vRealize Operations Cluster Nodes”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

To compare the cost of running workloads hosted with two different custom cloud providers, the administrator needs to create two new pricing cards in vRealize Operations. A pricing card is a template that defines the cost of cloud resources, such as compute, storage, network, and services. By creating two pricing cards, one for each custom cloud provider, the administrator can specify the prices for each resource type and apply discounts or markups as needed. The administrator can then use the pricing cards to run a what-if analysis and compare the cost of migrating or scaling workloads to the custom cloud providers. The other options are not correct for comparing the cost of running workloads hosted with two different custom cloud providers. Adding custom cloud providers as cloud accounts is not possible, as vRealize Operations only supports adding public cloud accounts, such as AWS, Azure, or Google Cloud. Inputting prices manually when running a what-if analysis is not efficient, as it would require entering the prices for each resource type and workload every time. Adding two custom cloud providers is not a valid option, as it is not clear how the administrator would define the cost of the cloud resources without using pricing cards. References: Create a Pricing Card, Compare the Cost of Running Workloads on Different Cloud Providers, What-If Analysis

vRealize Operations allows for different node sizes when deploying a cluster to suit various environments and scalability needs. The sizes typically include Small, Medium, and Large, and these sizes determine the capacity and performance of each node in a High Availability configuration.
