Free Practice Questions for VMware 5V0-35.21 Exam

 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, a vRealize Operations cluster consists of three types of nodes: primary, data, and remote collector. The primary node is the initial and required node that manages the cluster configuration and data synchronization. The data nodes are optional nodes that have adapters installed and perform data collection and analysis. The remote collector nodes are also optional nodes that can navigate firewalls, interface with remote data sources, reduce bandwidth consumption, and reduce the load on the analytics cluster. They only gather objects for the inventory, without storing data or performing analysis. Therefore, options A, C, and E are correct.

The other options are not correct because they are not types of nodes that make up the vRealize Operations cluster. Option B is not correct because the cloud connector is not a node, but a service that connects vRealize Operations to VMware Cloud services. Option D is not correct because the worker node is not a term used in vRealize Operations, but in vRealize Automation. Option F is not correct because the secondary node is also not a term used in vRealize Operations, but in vSphere Replication. References:

Service Discovery Overview

 According to the VMware vRealize Operations User Guide1, vRealize Operations allows the user to perform various actions on vSphere virtual machines from the product UI. These actions can help to manage, optimize, and troubleshoot the virtual machines and their resources. Some of the actions that can be performed on vSphere virtual machines from vRealize Operations product UI are:

Create virtual machine snapshot: This action creates a snapshot of the virtual machine, which is a point-in-time copy of the virtual machine state and data. A snapshot can be used to revert the virtual machine to a previous state, or to clone or migrate the virtual machine. The user can specify the name, description, and memory options for the snapshot.

Delete virtual machine snapshot: This action deletes a snapshot of the virtual machine, which frees up the disk space used by the snapshot. The user can select the snapshot to delete from a list of available snapshots for the virtual machine.

Move virtual machine: This action moves the virtual machine to a different host or cluster within the same vCenter Server. The user can select the destination host or cluster from alist of compatible and available options. The move action can help to balance the workload or improve the performance of the virtual machine.

Therefore, the correct answers are A. Create virtual machine snapshot, B. Delete virtual machine snapshot, and C. Move virtual machine, as these are three of the actions that can be performed on vSphere virtual machines from vRealize Operations product UI. References:

The administrator needs the Active Directory domain administrator account and password to configure service discovery to identify which virtual machines are running Active Directory services. 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 and services2. Credential-based service discovery uses the credentials provided by the administrator to log in to theguest operating system and run commands or scripts to discover the applications and services3. Credential-less service discovery can be used for most common applications and services, such as web servers, database servers, or file servers, but it has some limitations, such as not being able to discover clustered or distributed applications, or applications that run on non-standard ports4. Credential-based service discovery can be used for more complex and customized applications and services, such as Active Directory, Exchange, or SharePoint, but it requires the administrator to provide the appropriate credentials for each guest operating system. For Windows operating systems, the credentials must be either a local administrator account or a domain administrator account. For Active Directory services, the domain administrator account is preferred, as it has the necessary permissions to access the Active Directory information and configuration. Therefore, the administrator needs the Active Directory domain administrator account and password to configure service discovery to identify which virtual machines are running Active Directory services. No credentials are needed since credential-less service discovery can be used (option A) is not a correct answer, as credential-less service discovery cannot discover Active Directory services, which require credential-based service discovery. Local Windows administrator account and password (option B) is not a correct answer, as the local administrator account may not have the sufficient permissions to access the Active Directory information and configuration, which require the domain administrator account. Active Directory domain user account and password (option D) is not a correct answer, as the domain user account may not have the necessary permissions to access the Active Directory information and configuration, which require the domain administrator account. References:

According to the VMware vRealize Operations Install and Configure Guide1, when upgrading the vRealize Operations cluster via the Administration UI, the cluster status should change from offline to online after the upgrade process is completed. However, if the cluster status remains offline or fails during the upgrade, the administrator can use the Finish Installation option to resume the upgrade process. The Finish Installation option attempts to bring the cluster online and complete the upgrade. The administrator can monitor the progress of the upgrade from the Administration UI or the Cluster Management page.

The other options are not suitable for managing this problem and continuing the installation process. The Rollback Installation option is used to revert the cluster to the previous version of vRealize Operations, not to resume the upgrade process. The Rollback Installation option is only available if the cluster is online and the upgrade has failed. The administrator should not manually take the cluster offline, as this would interrupt the upgrade process and cause data loss or corruption. References:

According to the VMware vRealize Operations Reference Materials, two of the public cloud providers that are supported out-of-the-box in vRealize Operations What-If planning for public cloud costs are Microsoft Azure and Google Cloud. The What-If planning feature allows the administrator to compare the cost of running workloads in different public cloud providers, such as AWS, IBM Cloud, Microsoft Azure, Google Cloud, and Alibaba Cloud. The administrator can select the public cloud provider, the region, and the instance type, and then run the scenario to see the estimated monthly cost for the selected workloads. The administrator can also compare up to three public cloud providers at a time. The other options are incorrect because they are not supported out-of-the-box in vRealize Operations What-If planning for public cloud costs. Salesforce Cloud and Oracle Cloud are not among the public cloud providers that are available by default in vRealize Operations. However, the administrator can create a custom public cloud provider and upload a rate card to include them in the What-If planning. Alibaba Cloud is supported out-of-the-box in vRealize Operations What-If planning for public cloud costs, but it is not one of the correct answers, as only two options are required. 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 User Guide1, an automated action is a predefined or custom action that can be executed automatically when an alert is triggered. An automated action can help to resolve or prevent the problem that caused the alert, or to notify the relevant stakeholders. To allow an automated action to be triggered from an alert, two conditions must be met:

Within the active policy, the alert definition’s automated setting must be set to enabled. This allows the alert definition to trigger automated actions when the alert criteria are met. By default, the automated setting is disabled for all alert definitions, and must be manually enabled by the administrator.

The alert must have a recommendation attached to it. A recommendation is a suggested action that can help to resolve or prevent the problem that triggered the alert. A recommendation can include a link to a related topic in the documentation or an external URL. A recommendation can also be associated with an automated action, which can be executedby the system or by the user. An alert definition can have one or more recommendations, but only one of them can be associated with an automated action.

Therefore, the correct answers are B. Within the active policy, the alert definition’s automated setting must be set to enabled. and E. The alert must have a recommendation attached to it, as these are the two conditions that must be met to allow an automated action to be triggered from an alert. References:

 The reason why vRealize Operations reports that the cluster has 0 days remaining when the actual CPU overcommit ratio is less than the 4:1 configured value is that the CPU demand in the cluster is greater than the total CPU capacity. The allocation model is a method of calculating the capacity and utilization of resources based on the amount of resources that are allocated to the objects, such as virtual machines, clusters, or datastores. The allocation model allows the administrator to set the overcommit ratio for CPU, memory, or disk space, which is the ratio of the allocated resources to the available resources. The overcommit ratio determines how much the resources can be overcommitted without affecting the performance or availability of the objects1.

When the administrator enables the allocation model in a policy and sets the CPU overcommit ratio to 4:1 for all vSphere clusters in a vSphere datacenter, it means that the administrator allows the CPU resources to be allocated four times more than the availableCPU resources in the clusters. For example, if a cluster has 100 GHz of CPU capacity, the administrator can allocate up to 400 GHz of CPU resources to the virtual machines in the cluster. However, this does not mean that the virtual machines can consume up to 400 GHz of CPU resources without any impact. The actual CPU consumption of the virtual machines depends on the CPU demand, which is the amount of CPU resources that the virtual machines require to run their workloads. The CPU demand can vary depending on the workload type, intensity, and pattern2.

If the CPU demand in the cluster is greater than the total CPU capacity, it means that the virtual machines are requesting more CPU resources than the cluster can provide. This can result in CPU contention, performance degradation, and SLA violations. In this case, vRealize Operations reports that the cluster has 0 days remaining, which means that the cluster has reached its maximum capacity and cannot accommodate any more CPU demand. The cluster has 0 days remaining even if the actual CPU overcommit ratio is less than the 4:1 configured value, because the overcommit ratio only reflects the allocated resources, not the consumed resources. The overcommit ratio does not guarantee that the cluster can support the CPU demand of the virtual machines, but only indicates the potential capacity of the cluster based on the allocation model1.

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”.

Implementing vRealize Operations Cloud involves accessing the service, which is typically done by signing up or logging in through a web interface. Additionally, deploying and configuring a cloud proxy is essential as it acts as a bridge between your on-premises environment and the vRealize Operations Cloud. This proxy collects data from your environment and sends it securely to the cloud instance.
