• Workload Management is a feature of VMware vRealize Operations that enables self-driving operations management for hybrid and multi-cloud environments. It uses artificial intelligence and machine learning to monitor, analyze, and automate the performance, capacity, cost, and configuration of applications, infrastructure, and services12.
• Workload Management allows administrators to set a goal for workload optimization, which defines how vRealize Operations balances the resource utilization across clusters and data centers. The goal can be one of the following options34:
• Workload Management relies on VMware Distributed Resource Scheduler (DRS) and VMware Storage DRS to perform the workload optimization actions. DRS is a feature that automatically balances the compute resources and power consumption across the hosts in a cluster. Storage DRS is a feature that automatically balances the storage resources and I/O load across the datastores in a datastore cluster .
• To enable Workload Management to move a storage resource, such as a virtual disk or a virtual machine, Storage DRS must be enabled for the cluster that contains the storage resource. Storage DRS can be enabled or disabled at the cluster level, and can be configured with different automation levels, such as manual, fully automated, or partially automated .
• If Storage DRS is not enabled for the cluster, Workload Management cannot move the storage resource, as it does not have the permission or the mechanism to do so. This is the underlying reason for the problem. The other options are not relevant for moving a storage resource. DRS is only responsible for moving the compute resources, such as CPU and memory, not the storage resources. Storage DRS can be configured for both intra-datacenter and cross-datacenter migrations, not only for cross-datacenter migrations. The automation level of DRS does not affect the ability of Workload Management to move the storage resource, as long as Storage DRS is enabled.

 The vRealize Operations sizing tool is a web-based tool that helps you estimate the resources required for deploying and running vRealize Operations in your environment. The tool has two modes: Basic and Advanced. In the basic mode, you only need to enter information about vCenter objects, such as the number of clusters, hosts, virtual machines, and datastores. The tool also asks for the projected growth rate and data retention period for your environment. Based on these inputs, the tool provides recommendations for the node size, cluster size, and disk space for vRealize Operations. The tool also shows the maximum number of objects and metrics that can be collected by the recommendedconfiguration123. Therefore, the attribute that is required for using the vROps sizing tool in basic mode is the number of clusters. The other attributes, such as the number of virtual machine disks, vSwitches, and port groups, are not required in the basic mode. However, they can be entered in the advanced mode, along with other data sources, such as management packs, vRealize Automation, vRealize Log Insight, etc., to get a more accurate and customized sizing recommendation123. References: 1: Introducing the vRealize Operations Sizing Tool 2: vRealize Operations 8.6.0, 8.6.1, and 8.6.2 Sizing Guidelines 3: Everything You Need To Know About vRealize Operations Manager Sizing Tool

According to the VMware vRealize Operations Reference Materials, the three details that can be configured when creating a custom view are presentation, format, and data. The presentation option allows the administrator to select the view type, such as list, summary, trend, distribution, or text, and the visualization, such as table, chart, or heatmap. The presentation option also allows the administrator to configure the display settings, such as title, legend, labels, colors, and filters. The format option allows the administrator to select the output format, such as PDF, CSV, or XML, and the orientation, such as portrait or landscape. The format option also allows the administrator to configure the header and footer, such as logo, title, date, and page number. The data option allows the administrator to select the subject, which is the object type that applies to the view, and the data, which are the metrics, properties, or tags that are displayed in the view. The data option also allows the administrator to configure the data settings, such as aggregation, transformation, sorting, and grouping. The other options are incorrect because they are either not available or not relevant when creating a custom view. The custom view tag option is not available in the view configuration, but it can be used to filter the views in theview library. The input transformation option is not available in the view configuration, but it can be used to modify the input data for a widget in a dashboard. The subject option is not a separate detail, but a part of the data option in the view configuration. References: Create a View; View Configuration; View Types

VMware Tools is a base requirement of the virtual machine for non-credential based service discovery in a virtualization environment using vRealize Operations. Non-credential based service discovery leverages VMware Tools to discover services running on the virtual machines without requiring credentials. VMware Tools is a suite of utilities that enhances the performance and management of the virtual machines. It includes a service discovery plugin that enables vRealize Operations to collect information about the services and processes running on the virtual machines. The service discovery plugin uses netstat or ss commands to identify the services and their dependencies. VMware Tools also provides other benefits such as improved network and graphics performance, time synchronization, graceful power operations, and more. Therefore, VMware Tools is a base requirement of the virtual machine for non-credential based service discovery in vRealize Operations. References: Credential-Less Service Discovery with vRealize Operations; Service Discovery with VMware vRealize Operations; Service and Application Discovery

To view the status of all objects in vRealize Operations, you can create a dashboard by adding widgets or views. You can create and modify dashboards and configure them to meet your environment needs. Widgets are graphical elements that display data and analysis from vRealize Operations. Views are predefined or custom presentations of object data that you can use in dashboards, reports, or alerts. Alerts, recommendations, and reports are not objects that can be used to create dashboards, but they can be displayed or accessed from dashboards. References:

According to the vRealize Operations documentation, the Administrator role includes privileges to all features, objects, and actions in vRealize Operations, including creating and managing dashboards1. Therefore, if a user has been granted the Administrator role, they can create dashboards regardless of any other roles they may have. The ReadOnly role does not prevent the user from creating dashboards, as it only limits their access to read operations1. The ContentUser and DashboardManager roles are not required for creating dashboards, as they only provide privileges to manage specific content types1. References: 1: Roles and Privileges in vRealize Operations - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.10/com.vmware.vcom.core.doc/GUID-9F316466-FACA-4DA0-8F3E-51BC73793990.html)

 Exporting the dashboard from the development instance, and importing the dashboard into the other instance is the correct action to accomplish the goal. This method allows the administrator to share the dashboard configuration file (in JSON format) with other vROps instances, and edit the dashboard in the other instances as needed. Generating a custom URL, setting the expiration to “never expire”, and importing this URL into the other instance is not a valid option, as this method only allows the administrator to share a non-authenticated view of the dashboard, not the dashboard configuration file. Using the Embed option to import the HTML code into the other instances is not a feasible option, as this method only allows the administrator to embed the dashboard into a web page, not to import the dashboard configuration file. Connecting the vROps instances together, and synchronizing the dashboards is not a possible option, as vROps does not support thisfeature. References: Export and Import Dashboards, section “Export and Import Dashboards”. Options for Sharing Dashboards, section “Options for Sharing Dashboards”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

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 Docs(https://docs.vmware.com/en/vRealize-Operations/8.6/com.vmware.vcom.core.doc/GUID-B9095E9B-7F10-4B2F-95A9-3D54CF5038FF.html)  2: Service and Application Discovery - VMware Docs(https://docs.vmware.com/en/vRealize-Operations/8.10/com.vmware.vcom.core.doc/GUID-CC683117-D936-432C-B30B-CCCA08E863FB.html)  3: Configure Service and Application Discovery - VMware Docs(https://developer.vmware.com/apis/579/vra-advanced-designer/) : Create Application Definition - VMware Docs : Configure White List - VMware Docs
