According to the VMware vRealize Operations Reference Materials, primary nodes are responsible for managing the cluster configuration and synchronizing data across the cluster. They can also function as NTP servers for the cluster, ensuring that all nodes have the same time settings. Remote collector nodes, replica nodes, and data nodes rely on the primary nodes for NTP settings and cannot act as NTP servers themselves. References:

• vRealize Operations Manager Cluster Node Types
• Configuring NTP Settings

Removing the corrupted node, and then disabling and re-enabling vRealize Operations Manager High Availability to reassign the primary replica role to another existing node in the cluster is the correct way to resolve the availability issue within vRealize Operations Manager. This method ensures that the cluster can continue to operate with high availability and continuous availability, as the primary replica node is responsible for providing critical services that cannot be replicated across all cluster nodes, such as Global xDB, NTP server, and GemFire locator. By removing the corrupted node, the administrator can prevent any further issues or conflicts with the cluster configuration. By disabling and re-enabling vRealize Operations Manager High Availability, the administrator can trigger the cluster to select a new primary replica node from the existing data nodes, and synchronize the data and services with the primary node. Deploying a new vRealize Operations Manager node, and then adding it to the existing cluster is not a valid option, as it does not address the primary replica role assignment, and may cause additional problems with the cluster configuration. Cloning an existing primary vRealize Operations Manager node, and then adding it into the vRealize Operations Manager cluster is not a feasible option, as it may result in duplicate node IDs, IP addresses, and hostnames, and may cause conflicts with the cluster configuration. Asking the backup administrator to restore the corrupted primary replica node, and then refreshing the nodes from thevRealize Operations Manager administrator interface is not a reliable option, as it may take a long time to restore the node, and may not guarantee the consistency and integrity of the data and services on the node. References: Remove a Node from a Cluster, section “Remove a Node from a Cluster”. 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 User Guide1, tags are labels that can be assigned to objects in vRealize Operations to group them based on common attributes or criteria. Tags can be used to filter, search, and organize objects in vRealize Operations, as well as to define policies, alerts, dashboards, and reports. Tags can also be used to configure tiers, which are logical groups of objects that represent different levels of service or performance in the environment. For example, the administrator can create tiers such as Gold, Silver, and Bronze, and assign tags to the objects that belong to each tier. Then, the administrator can use the tags to apply different policies, alerts, or dashboards to each tier.

One of the grouping options in vRealize Operations that allows the configuration of tiers is Tags. This option allows the administrator to create custom groups based on the tags assigned to the objects. The administrator can select one or more tags to define the membership criteria for the custom group. The administrator can also specify the object type and the adapter type for the custom group. The custom group can then be used to configure tiers in vRealize Operations.

Therefore, the correct answer is A. Tags, as this is the grouping option in vRealize Operations that allows the configuration of tiers. References:

 To change the subscription options for a datacenter migration scenario, the administrator can use the Change Plan option in the Scenario Builder. This option allows the administrator to modify the plan type, duration, and discount for the selected cloud provider without running a new scenario. The Change Plan option also updates the cost and savings estimates based on the new subscription options. The other options are not relevant for changing the subscription options. Change Cloud Provider is used to switch to a different cloud provider for the scenario. Edit Configuration is used to modify the configuration settings, such as CPU, memory, and storage, for the scenario. Edit Discount is used to apply a custom discount percentage for the scenario. References: Change Plan, Scenario Builder, Create a Scenario for Data Center Migration

According to the VMware vRealize Operations Reference Materials, the users who are imported from an LDAP authentication source can access vSphere and other objects including third-party objects in vRealize Operations, as long as they have the appropriate permissions and roles assigned to them. The LDAP users can use their LDAP credentials to log in to vRealize Operations, and they can view and manage the objects that are within their scope of access. The other options are incorrect because they are either false or irrelevant. The credentials for the LDAP users are not stored in the central Postgres database of vRealize Operations, but in the LDAP server. The LDAP users are allowed to perform any actions in vRealize Operations that are permitted by their roles and permissions. The LDAP user password policy is not set by vRealize Operations, but by the LDAP server. References: Managing Users and Access Control in vRealize Operations; Authentication Sources; Give Administrator Access to AD or LDAP Users

The function that is unavailable in the vRealize Operations Admin UI is viewing alerts, symptoms, and policies. The Admin UI is a separate interface from the Product UI that provides access to selected maintenance functions beyond what the Product UI supports. TheAdmin UI is used for platform administration tasks, such as upgrading vRealize Operations, enabling or disabling High Availability (HA), uploading and installing vRealize Operations PAK files, taking vRealize Operations Online/Offline, and managing certificates, passwords, and users1. The Admin UI does not provide access to the operational functions, such as viewing alerts, symptoms, and policies, which are available in the Product UI. The Product UI is used for monitoring and managing the objects, metrics, alerts, dashboards, reports, and policies in vRealize Operations2.

 A vRealize Operations cluster in a Continuous Availability configuration consists of three node types: primary node, primary replica node, and witness node. These node types are deployed across two fault domains, which are separate physical locations that can tolerate failures of an entire rack or site. The witness node is deployed in a third location to monitor the network connectivity between the two fault domains and prevent split-brain scenarios1.

The primary node is the first node that is deployed in the cluster and acts as the master node. It is responsible for managing the cluster configuration, user interface, alerting, and reporting. The primary node is deployed in fault domain 11.

The primary replica node is the second node that is deployed in the cluster and acts as the backup node for the primary node. It is responsible for replicating and synchronizing the data and configuration from the primary node. The primary replica node can take over the functions of the primary node in case of a failure. The primary replica node is deployed in fault domain 21.

The witness node is the third node that is deployed in the cluster and acts as the arbitrator node. It is responsible for monitoring the network connectivity and availability of the primary node and the primary replica node. The witness node can detect a split-brain situation, which occurs when the network connection between the two fault domains is lost and both nodes assume the role of the master node. The witness node can resolve the split-brain situation by making one of the nodes offline to avoid data inconsistency. The witness node is deployed in a third location that is independent of the two fault domains1.

The other options are not node types that are configured in a Continuous Availability configuration. A secondary node is a node that is added to the cluster to increase the capacity and performance of the cluster. A secondary node can be deployed in either fault domain, but it is not required for Continuous Availability1. A remote collector node is a node that is deployed outside the cluster to collect data from remote or isolated data sources. A remote collector node can be deployed in any location, but it is not part of the Continuous Availability configuration2. A secondary replica node is not a valid node type in vRealize Operations.

 To access the Troubleshoot with Logs dashboard from vRealize Operations, the administrator must configure the vRealize Log Insight integration from the vRealize Operations interface and configure vRealize Operations in vRealize Log Insight. The Troubleshoot with Logs dashboard allows the administrator to view graphs of log events in the environment, or create custom sets of widgets to access the information that matters most. The dashboard requires the integration of vRealize Operations with vRealize Log Insight, which is a log management and analysis tool1. The integration can be done in twoways: by configuring the vRealize Log Insight adapter in vRealize Operations, or by configuring vRealize Operations in vRealize Log Insight. Both methods are necessary to access the Troubleshoot with Logs dashboard and the Logs tab in vRealize Operations2. References: 1: Troubleshoot with Logs Dashboard 2: Configuring vRealize Log Insight with vRealize Operations
