According to the vRealize Operations Cloud Getting Started guide1, the two steps that are needed to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance are:

• Deploy and configure a cloud proxy. A cloud proxy is a virtual appliance that acts as a bridge between the on-premises vCenter instance and the vRealize Operations Cloud instance. It collects data from the vCenter instance and sends it securely to the vRealize Operations Cloud instance. It also enables actions and remote console access from the vRealize Operations Cloud instance to the on-premises vCenter instance. The guide provides the steps to download, deploy, and configure the cloud proxy using the vRealize Operations Cloud user interface1.
• Add a vCenter cloud account. A vCenter cloud account is a configuration that defines the connection details and credentials of the on-premises vCenter instance. It also specifies the cloud proxy that is associated with the vCenter instance. The guide provides the steps to add a vCenter cloud account using the vRealize Operations Cloud user interface1.

The other options are not correct because:

• Deploying and configuring a Data node is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A Data node is a component of the vRealize Operations Cloud cluster that stores and processes data. It is managed by the vRealize Operations Cloud service provider and does not need to be deployed or configured by the customer2.
• Deploying and configuring a Primary node is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A Primary node is a component of the vRealize Operations Cloud cluster that provides the user interfaceand administration functions. It is managed by the vRealize Operations Cloud service provider and does not need to be deployed or configured by the customer2.
• Adding a vRealize Operations Cloud account is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A vRealize Operations Cloud account is a configuration that defines the connection details and credentials of the vRealize Operations Cloud instance. It is used to integrate vRealize Operations Cloud with other VMware Cloud services, such as VMware Cloud on AWS or VMware Cloud Director. It is not related to the on-premises vCenter instance3. References: 1: vRealize Operations Cloud Getting Started guide, pages 9-132: vRealize Operations Cloud Concepts guide, pages 5-63: vRealize Operations Cloud User Guide, pages 17-18.

To discover custom application services running on virtual machines, the administrator needs to install the vRealize Operations Service Discovery Management Pack1. This management pack enables service and application discovery using the Service Discovery adapter, which leverages the Telegraf agent to collect data from the end point VMs2. The administrator can configure the Service Discovery adapter to discover predefined and custom applications and services, and view their relationships and metrics in vRealize Operations3. The administrator can also create custom application definitions based on object names, tags, or properties, and import them as XML files. Configuring a white list is not a valid option, as it is used to filter out unwanted services from discovery. References: 1: vRealize Operations Service Discovery Management Pack - VMware 2: Service and Application Discovery - VMware 3: Configure Service and Application Discovery - VMware : Create Application Definition - VMware Docs : Configure White List - VMware Docs

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)
