 According to the VMware vRealize Operations Reference Materials, the cloud provider that needs to be added as a custom cloud provider when running a What-If Analysis is Oracle Cloud. The What-If Analysis feature allows the administrator to compare the cost and performance of running workloads in different public cloud providers, such as AWS, IBM Cloud, Microsoft Azure, Google Cloud, and Alibaba Cloud. These public cloud providers are supported out-of-the-box in vRealize Operations, and the administrator can select them from the predefined list when creating a migration scenario. However, if the administrator wants to compare the cost and performance of running workloads in Oracle Cloud, they need to add it as a custom cloud provider, and upload a rate card that contains the pricing information for Oracle Cloud services. The other options are incorrect because they are supported out-of-the-box in vRealize Operations, and they do not need to be added as a custom cloud provider when running a What-If Analysis. References: What-If-Analysis - Migration Planning: Public Cloud; VMware vRealize Operations What-If Analysis; VMware vRealize Operations for Public Cloud

According to the VMware vRealize Operations Reference Materials, the component that will be available when a user logs in to the vRealize Operations Product UI is the Dashboards page. The Dashboards page is the main interface of the Product UI, where the user can view and interact with various dashboards that display the data and analysis of the monitored objects and environments. The Dashboards page also allows the user to create and customize their own dashboards, as well as access other features such as alerts, reports, views, and policies. The other options are incorrect because they are not available in the Product UI, but in the Admin UI. The Software Update page, the Certificate management, and the System Status page are all components of the Admin UI, which is a separate interface that provides the administrative and configuration functions for the vRealize Operations cluster. The Admin UI can be accessed by logging in to the master node or the replica node of the cluster, using the admin user account or a user account with the Administrator role. The user who has access only to the Product UI cannot access the Admin UI or its components. References: vRealize Operations Manager Overview; Log in to vRealize Operations Manager; vRealize Operations Manager Administration

To enable east/west firewall in VMware Cloud Director Tenant Portal, you need to perform the following steps:

Login to Customer Organization and go to Networking Section of Tenant Portal. This is where you can access the networking capabilities provided by NSX Data Center for vSphere in your VMware Cloud Director organization virtual data center.

Go to Edge Gateways and enable firewall on one of the Edge Gateways. This will allow you to configure the edge gateway firewall rules for north/south traffic enforcement and perimeter security functionality. You can also enable other services such as NAT, VPN, load balancing, etc. on the edge gateway.

Go to Networking and enable Distributed Firewall for one of the Network inside the Network section. This will allow you to configure the distributed firewall rules for east/west traffic isolation and access control. You can also apply security policies and groups to the network and the virtual machines within it.

The Object List widget (A) is used to select objects. Once an object is selected, the Object Relationship widget (D, E) shows the relationship map of this selected object. To fulfill the requirement that the Alert List widget (F, G, H) should only show the active alerts for the selected object, the selection output of the Object List widget must be connected to both the Object Relationship and Alert List widgets.

Thus, you need to connect the output of the Object List widget (point B) to the input of the Object Relationship widget (point E), and also to the input of the Alert List widget (point G). This setup ensures that selecting an object in the Object List widget will update both the Object Relationship map and the Alert List with the relevant information for the selected object.

 To add a custom metric configuration file to a scoreboard widget in a dashboard, the correct process is to create a metric file in XML format, set the scoreboard widget Self Provider to Off, and create a widget interaction with a provider widget. A custom metric configuration file is a file that defines the metrics that the scoreboard widget displays for different object types. The file must be in XML format and follow a specific schema. The file must be uploaded to the vRealize Operations server and selected in the Metric Configuration option of the scoreboard widget. The Self Provider option determines whether the widget shows metrics of the objects selected during editing of the widget or selected on another widget. When the Self Provider option is set to Off, the widget shows metrics of the objects selected on another widget. The widget interaction is a mechanism that allows widgets to communicate with each other and pass data. A provider widget is a widget that provides data to another widget. A receiving widget is a widget that receives data from another widget. To create a widget interaction, the administrator must edit the dashboard and select the provider widget and the receiving widget, and then configure the interaction type and the data to pass. By creating a widget interaction with a provider widget, the administrator can enable the scoreboard widget to display the custom metrics for the objects selected on the provider widget. References: How the Scoreboard Widget and Configuration Options Work; Question on How to Scoreboard Dashboard - Metric Configuration XML - Max & Avg Metric Values; Dashboard widget can set default metric key

 According to the VMware vRealize Operations Reference Materials, interactions between widgets allow you to display data that shows dependencies between objects in your environment. For example, you can configure a widget to act as a provider or a receiver of data from another widget. When you select an object in the provider widget, the receiver widget updates to show the data related to that object. In this case, the list view widget should be configured as a provider, and the other widgets on the dashboard should be configured as receivers. This way, when the operator clicks on a virtual machine in the list view, the other widgets will show the relevant data for that virtual machine. Therefore, option D is correct.

The other options are not correct because they are not related to the problem of updating the widgets based on the selection in the list view. Option A is not correct because dashboard sharing is a feature that allows you to share a dashboard or a dashboard template with one or more user groups, but it does not affect the widget interactions. Option B is not correct because the Refresh Content option is a setting that allows you to refresh the data in a widget manually or automatically, but it does not affect the widget interactions. Option C is not correct because the object relationship widgets are a type of widgets that show the relationships between objects in your environment, such as parent-child, sibling, or peer relationships, but they are not related to the widget interactions. References:

The type of node that should be deployed to monitor a remote datacenter using an existing vRealize Operations Manager cluster is a Remote Collector node. A Remote Collector node is a node that is deployed in a remote datacenter location across a firewall, and collects data from the remote objects without performing analysis or storing data. A Remote Collector node can reduce the bandwidth consumption and the load on the vRealize Operations analytics cluster, and can also navigate firewalls and interface with remote data sources12. A Remote Collector node can be deployed on a different operating system than the rest of the cluster, and can support a round-trip time (RTT) of up to 200 ms3.

The other options are not correct, because they are not suitable for monitoring a remote datacenter with a high RTT. A Replica node is a node that is converted from a Data node to provide high availability (HA) or continuous availability (CA) for the vRealize Operations cluster. A Replica node is a copy of the Primary node, and must be deployed in the same datacenter as the Primary node1. A Data node is a node that performs data collection and analysis for the vRealize Operations cluster, and can be added to scale out the cluster capacity and performance. A Data node must be deployed in the same datacenter as the Primary node, and can support a RTT of up to 10 ms1. A Witness node is a node that is required for continuous availability (CA) of the vRealize Operations cluster, and acts as a decision maker in case of a network partition between two fault domains. A Witness node must be deployed in a third datacenter that is separate from the two fault domains, and can support a RTT of up to 100 ms1.

 The advanced sizing guide should be used instead of the basic sizing guide in the vRealize Operations Manager (vROps) online Sizing tool when additional management packs are going to be implemented. The basic sizing guide provides the default sizing recommendations based on the number of objects and metrics collected from the vSphere environment. However, if the monitored environment includes other types of objects and metrics from different sources, such as management packs, the basic sizing guide may not be accurate. The advanced sizing guide allows the user to specify the number of objects and metrics for each management pack and get a more precise sizing recommendation12. References: 1: vRealize Operations Sizing Guidelines 2: vRealize Operations 8 - VMware Docs

The cause of this issue is that changes made to scope, time, or potential evidence are not saved after logging out of the vRealize Operations user interface. The troubleshooting workbench feature allows the administrator to perform advanced troubleshooting tasks on an alert or an object by looking for potential evidences of a problem within a specific scope and time range. The administrator can modify the scope, time, or potential evidence in the active session, but these changes are not persistent and are lost when the administrator logs out or closes the browser1. The administrator can see the virtual machine context as a recent search because the recent searches are stored in the browser’s local storage, but the changes made to the troubleshooting workbench are not2.

The other options are not the cause of this issue. Option A is incorrect because the troubleshooting workbench feature is available in all editions of vRealize Operations, and the license edition does not affect the saving of the changes3. Option C is incorrect because there is no Save option when using the troubleshooting workbench, and the administrator cannot save the changes manually1. Option D is incorrect because restoring the vRealize Operations instance from an earlier backup would not affect the changes made to the troubleshooting workbench, as they are not stored in the vRealize Operations database or file system1.

To allow the newly added group members to login quickly into vRealize Operations, the administrator needs to synchronize the user groups from the Active Directory source and check if the automatic synchronization option is enabled. Synchronizing the user groups imports the latest user group information from the source to vRealize Operations. Checking the automatic synchronization option ensures that the user group membership is updated periodically without manual intervention. Re-adding or deleting the authentication source are not necessary steps, as they would disrupt the existing user access control. Adding a SAML IdP as authentication source is not relevant, as the question is about Active Directory groups. References: Import User Groups From Source, Export and Import of User Groups, Synchronize the Active Directory Groups for VMware Aria Operations in Workspace ONE Access
