VMware vRealize Operations - Cloud Management Automation 2023 Changed 5V0-35.21 Questions

 To estimate the monthly cost of running workloads in IBM Cloud, the administrator can use the What-If Analysis feature of vRealize Operations, which allows forecasting the impact of migrating a workload to a public cloud instance such as AWS, IBM Cloud, Microsoft Azure, Google Cloud or to VMware Cloud on AWS1. The administrator can select the Migration Planning option and choose IBM Cloud as the target cloud provider. Then, the administrator can import the existing VMs that support the business-critical applicationfrom the custom group in vRealize Operations and select all machines to be included in the scenario. Finally, the administrator can run the scenario and get the vRealize Operations analysis and assessment of the plan, which includes the cost and capacity information for the IBM Cloud region2. References: 1: What-If Analysis - Migration Planning: Public Cloud 2: Migration Planning

According to the vRealize Operations Cloud Getting Started guide1, the two steps that are needed to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance are:

• Deploy and configure a cloud proxy. A cloud proxy is a virtual appliance that acts as a bridge between the on-premises vCenter instance and the vRealize Operations Cloud instance. It collects data from the vCenter instance and sends it securely to the vRealize Operations Cloud instance. It also enables actions and remote console access from the vRealize Operations Cloud instance to the on-premises vCenter instance. The guide provides the steps to download, deploy, and configure the cloud proxy using the vRealize Operations Cloud user interface1.
• Add a vCenter cloud account. A vCenter cloud account is a configuration that defines the connection details and credentials of the on-premises vCenter instance. It also specifies the cloud proxy that is associated with the vCenter instance. The guide provides the steps to add a vCenter cloud account using the vRealize Operations Cloud user interface1.

The other options are not correct because:

• Deploying and configuring a Data node is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A Data node is a component of the vRealize Operations Cloud cluster that stores and processes data. It is managed by the vRealize Operations Cloud service provider and does not need to be deployed or configured by the customer2.
• Deploying and configuring a Primary node is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A Primary node is a component of the vRealize Operations Cloud cluster that provides the user interfaceand administration functions. It is managed by the vRealize Operations Cloud service provider and does not need to be deployed or configured by the customer2.
• Adding a vRealize Operations Cloud account is not a required step to onboard an on-premises vCenter instance into an existing vRealize Operations Cloud instance. A vRealize Operations Cloud account is a configuration that defines the connection details and credentials of the vRealize Operations Cloud instance. It is used to integrate vRealize Operations Cloud with other VMware Cloud services, such as VMware Cloud on AWS or VMware Cloud Director. It is not related to the on-premises vCenter instance3. References: 1: vRealize Operations Cloud Getting Started guide, pages 9-132: vRealize Operations Cloud Concepts guide, pages 5-63: vRealize Operations Cloud User Guide, pages 17-18.

 The frequency at which new services are discovered when using Service Discovery in vRealize Operations is every 5 minutes. Service Discovery is a feature of vRealize Operations that allows the administrator to discover and monitor the applications and services running on the virtual machines in the environment1. Service Discovery can be performed using two methods: credential-less and credential-based. Credential-less Service Discovery uses VMware Tools to query the guest operating system for the list of running processes, and then matches them with a predefined set of signatures to identify the applications andservices2. Credential-based Service Discovery uses the credentials provided by the administrator to log in to the guest operating system and run commands or scripts to discover the applications and services3. Credential-less Service Discovery collects the information about the services running inside the guest every five minutes4. Credential-based Service Discovery collects the information about the services running inside the guest every 24 hours5. Therefore, the frequency at which new services are discovered when using Service Discovery in vRealize Operations depends on the method used, but the most frequent one is every 5 minutes for credential-less Service Discovery. References:

To enable High Availability (HA) on a vRealize Operations cluster, the following two options are requirements:

• The cluster must have at least one Primary node: The primary node is the first node that is deployed in the cluster and it is responsible for managing the cluster configuration, user interface, and administration functions. The primary node also stores data and performs analytics like any other data node. Without a primary node, the cluster cannot function properly1.
• The cluster must have at least one Data node: A data node is a node that collects data from various sources, stores data in its local file system, and performs analytics and alerting functions. A data node also participates in the cluster load balancing and data replication. To activate HA, you must have at least one data node deployed, in addition to the primary node. This allows the creation of a replica node that can take over the primary node functions in case of a failure2. References: 1: About vRealize Operations High Availability 2: High Availability (HA)
