According to the VMware vRealize Operations Reference Materials, the Wait Cycle and the Cancel Cycle are the settings that determine how long a symptom condition must be true or false before the symptom is triggered or cancelled. The default cycle for both settings is 5 minutes, which means that each cycle corresponds to one collection interval of 5 minutes. Therefore, if a symptom has a Wait Cycle of 3 and a Cancel Cycle of 2, it will take 15 minutes (3 cycles x 5 minutes) for the symptom to be triggered after the condition becomes true, and 10 minutes (2 cycles x 5 minutes) for the symptom to be cancelled after the condition becomes false. The other options are incorrect because they do not match the calculation based on the given settings and the default cycle. References: Symptom Definition Settings; Alert Definition Best Practices

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.

 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.
