Correct Answer: C
C

Explanation:

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 the guest 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.

Question #12

An administrator is configuring Workload Optimization to maximize the workload performance.

Which configuration proactively moves workloads so that the resource utilization ensures maximum headroom for all resources?

A . Buffer
B . Moderate
C . Balance
D . Consolidate

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

Workload Optimization is a feature of VMware vRealize Operations that enables self-driving operations management for hybrid and multi-cloud environments. It uses artificial intelligence and machine learning to monitor, analyze, and automate the performance, capacity, cost, and configuration of applications, infrastructure, and services12.

Workload Optimization allows administrators to set a goal for workload optimization, which defines how vRealize Operations balances the resource utilization across clusters and data centers. The goal can be one of the following options34:

Balance: This option proactively moves workloads so that the resource utilization ensures maximum headroom for all resources. This means that vRealize Operations tries to distribute the workload evenly across the clusters and data centers, and avoid resource contention or overcommitment. This option is suitable for scenarios where workload performance is the first priority, and where there is a need for extra space for growth or spikes in demand.

Moderate: This option minimizes the workload contention by moving workloads away from clusters and data centers that are experiencing high resource utilization. This means that vRealize Operations tries to reduce the risk of performance degradation or SLA violations by ensuring that there is enough capacity to meet the workload demand. This option is suitable for scenarios where workload availability and reliability are the main goals, and where there is a moderate tolerance for resource imbalance or inefficiency.

Consolidate: This option proactively minimizes the number of clusters and data centers used by workloads by moving workloads to the clusters and data centers that have the lowest resource utilization. This means that vRealize Operations tries to optimize the resource efficiency and reduce the operational cost by freeing up unused or underutilized resources. This option is suitable for scenarios where workload consolidation and cost optimization are the primary objectives, and where there is a high tolerance for resource contention or overcommitment.

Therefore, the configuration that proactively moves workloads so that the resource utilization ensures maximum headroom for all resources is Balance.

Question #13

Users have reported several application VMs are performing very slowly. The system administrator was requested to find out the source of the problem on both VMs and/or ESXi hosts level. vRealize Operations has not been configured with Application Remote Collector.

Which action will help the administrator to quickly identify the underlying problem?

A . Under Inventory, select Manage Agent, then select the VMs, and run Remote Checks on ICMP, HTTP checks.
B . Under Report, use Configuration Report – Virtual Machines to list down possible changes that have occurred.
C . Under Administration, choose Configuration, select Object Relationships, and then identify the VMs and ESXi hosts relationship to generate a correlation of the metric, and finally, isolate the issue.
D . Under Dashboard, choose the out-of-the-box Performance dashboards that displays contention on both VMs and ESXi hosts.

Reveal Solution Hide Solution

Correct Answer: D
D

Explanation:

According to the vRealize Operations User Guide1, one of the best ways to quickly identify the underlying problem of slow application VMs is to use the out-of-the-box Performance dashboards that display contention on both VMs and ESXi hosts. These dashboards show the key performance indicators (KPIs) of CPU, memory, disk, and network for the selected objects, and highlight any contention or saturation issues that may affect the performance. The administrator can use these dashboards to drill down into the details of the metrics, alerts, events, and properties of the objects, and isolate the root cause of the problem. The other options are not correct because:

Under Inventory, selecting Manage Agent, then selecting the VMs, and running Remote Checks on ICMP, HTTP checks is not a helpful action, as it only verifies the connectivity and availability of the VMs, but does not provide any information about the performance or contention of the VMs or the ESXi hosts2.

Under Report, using Configuration Report – Virtual Machines to list down possible changes that have occurred is not a helpful action, as it only shows the configuration details of the VMs, such as name, UUID, power state, guest OS, CPU, memory, disk, and network, but does not show any performance or contention metrics or alerts of the VMs or the ESXi hosts3.

Under Administration, choosing Configuration, selecting Object Relationships, and then identifying the VMs and ESXi hosts relationship to generate a correlation of the metric, and finally, isolate the issue is not a helpful action, as it only shows the hierarchical and logical relationships between the objects, such as parent, child, sibling, and peer, but does not show any performance or contention metrics or alerts of the objects4.

Question #15

What is the minimum number of fault domains required to achieve vRealize Operations continuous availability with a primary node, data node, and witness node?

A . 4
B . 1
C . 3
D . 2

Question #16

To meet a requirement for protection against data loss in the event of a physical rack failure, an administrator is deploying a vRealize Operation cluster in a Continuous Availability configuration.

Which three node types will be configured within this scenario? (Choose three.)

A . Secondary Replica node
B . Remote Collector node
C . Primary Replica node
D . Primary node
E . Witness node
F . Secondary node

Reveal Solution Hide Solution

Correct Answer: C D E
C D E

Explanation:

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.

C . The alert will not require an attached recommendation.
D . The alert must have a recommendation but does not require symptom definitions.

Question #19

Which regulatory, standards-based compliance pack is available in vRealize Operations?

A . Sarbanes-Oxley Act (SOX)
B . Common Vulnerabilities and Exposures (CVE)
C . CIS Security Standards
D . General Data Protection Regulation (GDPR)

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

The regulatory, standards-based compliance pack that is available in vRealize Operations is the CIS Security Standards. The CIS Security Standards are a set of best practices and recommendations for securing IT systems and data against cyberattacks. The CIS Security Standards are developed and maintained by the Center for Internet Security (CIS), a nonprofit organization that provides cybersecurity resources and guidance to organizations and individuals1. The vRealize Operations Compliance Pack for CIS provides alerts, policies, and reports to validate the vSphere resources against the CIS hardening guide. The following resources are being validated using this content: ESXi Host, Virtual Machine, vCenter Server, Distributed Switch, Distributed Port Group, and Distributed Firewall2. The vRealize Operations Compliance Pack for CIS can be downloaded and installed from the VMware Marketplace3. The Sarbanes-Oxley Act (SOX) (option A) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. SOX is a federal law that regulates the financial reporting and auditing of public companies in the United States. SOX does not provide specific technical guidelines or benchmarks for securing IT systems and data4. The Common Vulnerabilities and Exposures (CVE) (option B) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. CVE is a list of publicly known cybersecurity vulnerabilities and exposures that are assigned unique identifiers and descriptions. CVE does not provide specific security standards or recommendations for securing IT systems and data5. The General Data Protection Regulation (GDPR) (option D) is not a regulatory, standards-based compliance pack that is available in vRealize Operations. GDPR is a legal framework that regulates the collection, processing, and transfer of personal data of individuals in the European Union and the European Economic Area. GDPR does not provide specific technical guidelines or benchmarks for securing IT systems and data.

Question #20

Which two options can be applied as a super metric? (Choose two.)

A . The average CPU usage of VMs within a Datacenter
B . The difference of CPU utilization for each VM between two defined time stamps
C . String operators that are valid to be used with mathematical calculations in a function
D . Count of Non-Windows VMs in a vSphere cluster
E . The average SCSI count with disk size of VMs within an ESXi host

Reveal Solution Hide Solution

Correct Answer: A, D
A, D

Explanation:

A super metric is a mathematical formula that contains one or more metrics or properties for one or more objects. It can be used to create custom metrics that are specific to your environment and can help you gain deeper insights into the performance and health of your infrastructure1. Super metrics can be applied to any object type that contains the objects or metrics involved in the formula2.

Option A is a valid super metric, as it calculates the average CPU usage of VMs within a Datacenter, which is an object type that contains VMs as child objects. The formula for this super metric could be something like avg(${this, metric=cpu|usage_average, depth=1}), which means the average of the CPU usage average metric for all the child objects of the current object3.

Option D is also a valid super metric, as it counts the number of Non-Windows VMs in a vSphere cluster, which is an object type that contains VMs as child objects. The formula for this super metric could be something like count(${this, metric=guestfilesystem|osType, depth=1, where=not contains windows}), which means the count of the guest OS type metric for all the child objects of the current object, where the value does not contain the word windows3.

Option B is not a valid super metric, as it involves the difference of CPU utilization for each VM between two defined time stamps, which is not a metric or property that can be used in a super metric formula. Super metrics can only use metrics or properties that are collected by vRealize Operations, not arbitrary time stamps2.

Option C is not a valid super metric, as it involves string operators that are valid to be used with mathematical calculations in a function, which is not a metric or property that can be used in a super metric formula. Super metrics can only use numerical values, not string values, in mathematical calculations2.

Option E is not a valid super metric, as it involves the average SCSI count with disk size of VMs within an ESXi host, which is not a metric or property that can be used in a super metric formula. Super metrics can only use metrics or properties that are available for the object type that the super metric is assigned to, and the SCSI count and disk size are not available for the ESXi host object type2.
