To enable High Availability (HA) on a vRealize Operations cluster, the following two options are requirements:

• The cluster must have at least one Primary node: The primary node is the first node that is deployed in the cluster and it is responsible for managing the cluster configuration, user interface, and administration functions. The primary node also stores data and performs analytics like any other data node. Without a primary node, the cluster cannot function properly1.
• The cluster must have at least one Data node: A data node is a node that collects data from various sources, stores data in its local file system, and performs analytics and alerting functions. A data node also participates in the cluster load balancing and data replication. To activate HA, you must have at least one data node deployed, in addition to the primary node. This allows the creation of a replica node that can take over the primary node functions in case of a failure2. References: 1: About vRealize Operations High Availability 2: High Availability (HA)

Expected Utilization is the workload option that should be included in the scenario to simulate 25% utilization of the resources. Expected Utilization is a percentage value that indicates how much of the allocated resources (CPU, memory, and storage) are expected to be used by the workload. By setting the Expected Utilization to 25%, the administrator can model the impact of adding or removing a workload that consumes 25% of the resources in the datacenter. Memory, Annual Projected Growth, and CPU are not workload options, but workload attributes. Memory and CPU are the amount of resources allocated to the workload, and Annual Projected Growth is the percentage by which the workload is expected to grow each year. These attributes do not directly specify the utilization of the resources by the workload. References: What-If Analysis - Workload Planning: Traditional, section “How What-If Analysis - Workload Planning: Traditional Works”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

 Cloud Proxies are special types of remote collectors that enable vRealize Operations Cloud to collect and monitor data from on-premises data centers. Cloud Proxies establish a one-way communication channel from the on-premises environment to the vRealize Operations Cloud, and they securely upload data to the cloud instance without requiring any inbound ports to be opened on the firewall. Cloud Proxies can support multiple vCenter Server accounts and other management packs, and they provide data persistence and high availability features12. References: 1: Configuring Cloud Proxies in vRealize Operations 2: Managing Cloud Proxies in vRealize Operations
