 The alert action that the administrator should take to stop the alert from triggering again, unless the problem occurs in the future, is to cancel the alert. Canceling the alert removes the alert from the active alerts list and stops the alert from affecting the state of the object. However, canceling the alert does not resolve the underlying conditions that triggered the alert. Therefore, the administrator should only cancel the alert after investigating and resolving the problem. If the problem occurs again in the future, the alert will be triggered again. To cancel an alert, the administrator can select the alert in the alerts list, click Actions, and click Cancel Alert. Alternatively, the administrator can open the alert details, click Actions, and click Cancel Alert. References: Monitoring Alerts in vRealize Operations Manager; User Scenario: Respond to an Alert in the Health Alert List

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 add an additional data node to the existing vRealize Operations cluster, you need to deploy a new data node from the Administration Ul. A data node is a node that collects, stores, processes, and analyzes data from your environment. You can expand an existing installation to add a data node by following these steps1:

• In a Web browser, navigate to the name or IP address of the node that will become the data node. The setup wizard appears, and you do not need to log in to vRealize Operations.
• Click Expand an Existing Installation.
• Click Next.
• Enter a name for the node (for example, Data-1).
• From the Node Type drop-down, select Data.
• Enter the FQDN or IP address of the primary node and click Validate.
• Select Accept this certificate and click Next.
• Verify the vRealize Operations administrator username of admin.
• Enter the vRealize Operations administrator password.
• Click Next, and click Finish.

The other options are not correct because they do not deploy a new data node from the Administration Ul. Option A is incorrect because cloning an existing data node is not supported and may cause data inconsistency. Option C is incorrect because deploying a new virtual appliance from an OVF file is not enough to add a data node to the cluster. You still need to configure the node type and join the cluster from the Administration Ul. Option D is incorrect because enabling High Availability in the Administration Ul does not add a data node to the cluster. It only creates a replica of the primary node for failover purposes. References: Expand an Existing Installation to Add a Data Node
