VMware Updated 5V0-35.21 Exam Questions and Answers by alby

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

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:

The Object List widget (A) is used to select objects. Once an object is selected, the Object Relationship widget (D, E) shows the relationship map of this selected object. To fulfill the requirement that the Alert List widget (F, G, H) should only show the active alerts for the selected object, the selection output of the Object List widget must be connected to both the Object Relationship and Alert List widgets.

Thus, you need to connect the output of the Object List widget (point B) to the input of the Object Relationship widget (point E), and also to the input of the Alert List widget (point G). This setup ensures that selecting an object in the Object List widget will update both the Object Relationship map and the Alert List with the relevant information for the selected object.

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)
