A vROps cluster in a Continuous Availability configuration consists of two fault domains, which are separate physical locations that can tolerate failures of an entire rack or site. The fault domains contain the primary node, the primary replica node, and the data nodes that store and replicate the data and configuration of the cluster. The witness node is deployed in a third location to monitor the network connectivity between the two fault domains and prevent split-brain scenarios, which occur when both fault domains assume the role of the master node due to network isolation1.

When a network outage occurs between the two fault domains, the witness node detects the situation and makes one of the fault domains offline to avoid data inconsistency. The fault domain that can still contact the witness node remains online and continues to function as the master node. The fault domain that cannot contact the witness node goes offline and stops serving requests. The VMs on the offline fault domain are restarted on the online fault domain by the vSphere HA feature1.

When the network outage is resolved and the connectivity between the two fault domains is restored, the vROps cluster will bring the offline fault domain back automatically. The offline fault domain will resync the data and configuration from the online fault domain and resume its normal operations. The administrator does not need to bring the offline fault domain online manually or restart and resync the vROps cluster1.

Therefore, the two events that will occur as a result of the outage are A. The vROps cluster will bring the fault domain back automatically once the network has been restored and D. One fault domain will go offline.

 According to the vRealize Operations Sizing Guidelines, the supported node configurations during installation are Large, Very Large, and Medium. These are the default configurations that VMware offers based on the number of objects and metrics to be monitoredby vRealize Operations. Each configuration has a different amount of vCPU, memory, disk space, and network requirements. The administrator can choose the configuration that best suits the existing infrastructure and the expected growth of the environment1.

The other options are not supported node configurations during installation. Tiny and Small are not valid configurations for vRealize Operations 8.x and later versions. These configurations were available for vRealize Operations 6.x and 7.x versions, but they are not recommended for production environments due to their limited capacity and performance2. No limit is not a configuration option, but a statement that indicates that there is no upper limit on the number of nodes that can be added to a vRealize Operations cluster. However, the number of nodes depends on the node configuration, the network latency, and the data source type3.

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

According to the VMware vRealize Operations Reference Materials, the High Availability feature in vRealize Operations cluster must be used for this requirement. The High Availability feature enables the cluster to tolerate one node failure without losing any data or functionality. The High Availability feature works by creating a replica node for each data node in the cluster, and synchronizing the data between them. The replica node acts as a standby node that can take over the role of the data node in case of a failure. The replica node can also serve as a load balancer to distribute the workload among the data nodes. The other options are incorrect because they do not meet the requirement or they are not supported by vRealize Operations. The Remote Collector option is not a cluster feature, but a type of node that can be used to collect data from remote sources and forward it to the cluster. The Remote Collector node does not store any data or perform any analysis, and it cannot replace a data node in case of a failure. The Continuous Availability option is a cluster feature that enables the cluster to tolerate multiple node failures without losing any data or functionality. However, the Continuous Availability feature requires at least two physical locations, and it is not supported for a single location. The Stretched Cluster option is not a cluster feature, but a configuration that allows a cluster to span across two physical locations. The Stretched Cluster option can provide high availability and disaster recovery, but it also requires additional network and storage configuration, and it is not supported for a single location. References: vRealize Operations Cluster and Node Maintenance; Adding High Availability to vRealize Operations; Adding Continuous Availability; Stretched Cluster

Data nodes are the type of node in a vRealize Operations (vROps) design that allow an administrator to scale out vROps to monitor very large environments. Data nodes are additional nodes that have all the vROps services installed, such as UI, Controller, Analytics, Collector, and Persistence. Data nodes perform data collection and analysis, and increase the capacity and performance of the vROps cluster. Data nodes can be added or removed as needed to adjust to the changing workload and environment size. Remote collectors are not a type of node in a vROps design, but a separate component that can be deployed to collect data from remote sources and send it to the vROps cluster. Remote collectors do not store data or perform analysis, and do not increase the capacity or performance of the vROps cluster. Replica Primary nodes and Primary nodes are not the type of node that allow an administrator to scale out vROps to monitor very large environments, but the type of node that provide high availability and continuous availability for the vROps cluster. Replica Primary nodes and Primary nodes contain critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. Replica Primary nodes and Primary nodes do not perform data collection and analysis, and do not increase the capacity or performance of the vROps cluster. References: About vRealize Operations Cluster Nodes, section “About vRealize Operations Cluster Nodes”. vRealize Operations Manager User Guide, section “Create and Configure Dashboards”.

According to the VMware vRealize Operations Install and Configure Guide1, the sizing tool is a web-based application that helps to estimate the required resources and configuration for a vRealize Operations cluster. The sizing tool takes into account various parameters,such as the number and type of objects to be monitored, the number of metrics and properties to be collected, the number of alerts and dashboards to be displayed, the number of users and concurrent sessions, and the desired availability and performance of the cluster.

Two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool are:

Time Series Data Retention: This parameter specifies the duration for which the collected metrics and properties are stored in the vRealize Operations database. The longer the retention period, the more disk space is required for the cluster nodes. The sizing tool allows the user to select the retention period from 1 month to 12 months, or to enter a custom value.

Projected Growth: This parameter specifies the expected increase in the number and type of objects to be monitored over time. The higher the projected growth, the more resources are required for the cluster nodes. The sizing tool allows the user to select the projected growth from 0% to 100%, or to enter a custom value.

Therefore, the correct answers are A. Time Series Data Retention and C. Projected Growth, as these are two of the additional parameters that are taken into account when sizing a vRealize Operations cluster using the sizing tool. References:

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

The troubleshooting workbench is a feature of vRealize Operations that provides a unified and interactive view of the alerts, metrics, events, and logs related to an object or a problem in your environment. You can use the troubleshooting workbench to quickly identify the root cause of an issue, analyze the impact and symptoms, and take corrective actions12.

The troubleshooting workbench can show the data from other vRealize Suite products when the integration is configured. The integration enables vRealize Operations to collect and display the data from the other products as additional sources of information and context for troubleshooting purposes. The integration also enables vRealize Operations to launch the other products from the troubleshooting workbench to perform further analysis or actions34.

The other vRealize Suite product that can show its data in the troubleshooting workbench when the integration is configured is vRealize Network Insight. vRealize Network Insight is a product that provides visibility and analytics for network and security across physical, virtual, and cloud environments. It helps you to plan, operate, troubleshoot, and optimize your network and security infrastructure, as well as ensure compliance and security posture56.

When vRealize Operations is integrated with vRealize Network Insight, you can see the network and security data from vRealize Network Insight in the troubleshooting workbench. For example, you can see the network flows, firewall rules, network paths, and network health of the objects or problems that you are troubleshooting. You can also launch vRealize Network Insight from the troubleshooting workbench to perform deeper network and security analysis or actions .

vRealize Operations Cloud is the SaaS offering of vRealize Operations that provides the same features and capabilities as the on-premises version, but with the benefits of faster time to value, lower operational costs, and continuous innovation. vRealize Operations Cloud supports near real-time monitoring of your applications and infrastructure, with data collection intervals as low as 20 seconds1. Near real-time monitoring enables you to detect and troubleshoot performance issues, optimize resource utilization, and ensure SLA compliance more effectively. vRealize Operations Cloud also integrates with other VMware Cloud services, such as VMware Cloud on AWS, VMware Cloud on Dell EMC, and VMware Tanzu Mission Control, to provide unified visibility and management across your hybrid and multi-cloud environments2.

The on-premises editions of vRealize Operations (Standard, Advanced, and Enterprise) do not support near real-time monitoring, as the minimum data collection interval is 5 minutes3. Therefore, they are not suitable for scenarios that require faster and more granular data analysis and alerting. The on-premises editions also have different feature sets and licensing models compared to vRealize Operations Cloud4. 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)
