Custom groups are collections of objects that you define based on criteria that you specify. You can use custom groups to assign different vRealize Operations policies to a particular set of objects that share common characteristics or belong to a specific business unit1. Custom groups allow you to override the default policy settings for the objects in the group and apply a different policy that suits your requirements2. For example, you can create a custom group of ESXi clusters that run database servers and assign a different capacity policy to them than the rest of the clusters in your environment2. References: = 1 Managing Custom Object Groups in vRealize Operations - VMware Docs, 2 Policies - VMware Docs

 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. References: 1: vRealize Operations User Guide, pages 57-59, 62-632: vRealize Operations User Guide, pages 69-703: vRealize Operations User Guide, pages 81-824: vRealize Operations User Guide, pages 84-85.

 Cloud Proxies are special types of remote collectors that enable vRealize Operations Cloud to collect and monitor data from on-premises data centers. Cloud Proxies establish a one-way communication channel from the on-premises environment to the vRealize Operations Cloud, and they securely upload data to the cloud instance without requiring any inbound ports to be opened on the firewall. Cloud Proxies can support multiple vCenter Server accounts and other management packs, and they provide data persistence and high availability features12. References: 1: Configuring Cloud Proxies in vRealize Operations 2: Managing Cloud Proxies in vRealize Operations
