At ValidExamDumps, we consistently monitor updates to the VMware 5V0-35.21 exam questions by VMware. Whenever our team identifies changes in the exam questions,exam objectives, exam focus areas or in exam requirements, We immediately update our exam questions for both PDF and online practice exams. This commitment ensures our customers always have access to the most current and accurate questions. By preparing with these actual questions, our customers can successfully pass the VMware vRealize Operations Specialist exam on their first attempt without needing additional materials or study guides.
Other certification materials providers often include outdated or removed questions by VMware in their VMware 5V0-35.21 exam. These outdated questions lead to customers failing their VMware vRealize Operations Specialist exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the VMware 5V0-35.21 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
Which three key benefits does vRealize Operations provide within an environment? (Choose three.)
vRealize Operations provides the following three key benefits within an environment:
Capacity optimization: vRealize Operations helps you optimize the capacity of your infrastructure and applications by providing visibility, analysis, planning, and automation. You can monitor and forecast the demand, supply, and utilization of resources, identify and reclaim unused or overprovisioned resources, balance the workload across clusters and datastores, and plan for future growth or consolidation scenarios. You can also automate the capacity optimization actions based on policies and alerts.
Performance optimization: vRealize Operations helps you optimize the performance of your infrastructure and applications by providing real-time and historical metrics, alerts, dashboards, and reports. You can monitor and troubleshoot the health, risk, and efficiency of your environment, identify and resolve performance issues, analyze the root cause and impact of problems, and optimize the configuration and placement of your workloads. You can also automate the performance optimization actions based on policies and alerts.
Monitoring and troubleshooting: vRealize Operations helps you monitor and troubleshoot your environment by providing comprehensive and integrated visibility across physical, virtual, and cloud infrastructures. You can collect and analyze data from various sources, such as vSphere, NSX, vSAN, Kubernetes, AWS, Azure, etc., and correlate them to provide a unified view of your environment. You can also leverage artificial intelligence and machine learning to detect anomalies, generate smart alerts, and provide recommendations. You can also use various tools, such as dashboards, heat maps, topology maps, logs, etc., to drill down into the details and resolve issues faster.
When Workload Planning is performed, it returns that an existing cluster does not have the capacity to accommodate the selected virtual machines.

An administrator is configuring Workload Optimization to minimize the workload contention across clusters by reducing vMotion operations.
Which setting should be configured to meet this goal?
According to the VMware vRealize Operations Reference Materials, Workload Optimization is a feature that allows you to automatically balance and optimize workloads across your virtualized infrastructure. Workload Optimization has four settings that determine how aggressively it moves workloads between clusters: Moderate, Balance, Consolidate, and Buffer. Each setting has a different impact on the number of vMotion operations, the cluster headroom, and the workload contention.
The Consolidate setting is the most aggressive setting that aims to minimize the workload contention across clusters by reducing the number of clusters used and maximizing the utilization of each cluster. The Consolidate setting performs the most vMotion operations, leaves the least cluster headroom, and has the lowest workload contention. The Consolidate setting is suitable for environments that have overprovisioned clusters and want to free up some clusters for other purposes or reduce the infrastructure costs. Therefore, option C is correct.
The other options are not correct because they do not meet the goal of minimizing the workload contention across clusters by reducing vMotion operations. Option A is not correct because the Moderate setting is the least aggressive setting that aims to maintain the current state of the clusters and avoid unnecessary vMotion operations. The Moderate setting performs the least vMotion operations, leaves the most cluster headroom, and has the highest workload contention. The Moderate setting is suitable for environments that have stable clusters and do not want to disrupt the existing workload placement. Option B is not correct because the Balance setting is a moderate setting that aims to balance the workload distribution across clusters and improve the performance of the clusters. The Balance setting performs a moderate number of vMotion operations, leaves a moderate cluster headroom, and has a moderate workload contention. The Balance setting is suitable for environments that have some imbalanced clusters and want to optimize the workload placement. Option D is not correct because the Buffer setting is a conservative setting that aims to create more cluster headroom and reduce the risk of resource shortage. The Buffer setting performs a low number of vMotion operations, leaves a high cluster headroom, and has a low workload contention. The Buffer setting is suitable for environments that have unpredictable or bursty workloads and want to ensure enough capacity for future demand.References:

An administrator wants to configure vRealize Operations to operate in Continuous Availability mode for resiliency. The administrator has deployed all required nodes, registered the nodes as members of the vRealize Operations cluster, and must now configure the Continuous Availability mode.
How should this configuration be completed?
What are the two required components of an alert definition? (Choose two.)
Symptom: A symptom is a condition that indicates a deviation from the normal or expected behavior of an object. A symptom can be based on metrics, properties, events, or messages. A symptom can have a severity level and a wait cycle. A symptom is a required component of an alert definition, as it triggers the alert when it is met.
Recommendation: A recommendation is a suggestion or a guidance that provides a possible solution or a mitigation for the issue that caused the alert. A recommendation can include a link to a relevant document or a workflow. A recommendation is an optional component of an alert definition, as it helps the user to resolve the alert, but it does not affect the alert generation.
Action: An action is a task or a workflow that can be executed automatically or manually to resolve the issue that caused the alert. An action can be based on vRealize Orchestrator workflows or vRealize Operations Manager tasks. An action is a required component of an alert definition, as it defines the response for the alert when it is generated.
Node: A node is a vRealize Operations Manager instance that is part of a cluster. A node is an optional component of an alert definition, as it helps the user to specify the scope and the source of the alert definition, but it does not affect the alert generation.
Therefore, the two required components of an alert definition are symptom and action, while the other components are optional.References:
