An administrator is working on reclamation options in a virtualization environment and has discovered that a Powered-Off VM (SRV-A) is showing as a candidate for reclamation.
The administrator researched SRV-A and finds out that the server is only used and powered-on the first three days of a month. The administrator needs to prevent this server as a candidate for reclamation.
Which action, if any, should the administrator take to meet this goal?
A database administrator needs an overview for all the database servers in vRealize Operations for the next seven days for performance testing. An vRealize Operations administrator creates a custom dashboard with all the required metrics.
The following requirements needs to be accomplished:
Database server admin group don't have access to the vRealize Operations instance.
Access to the dashboard should only be available during the mentioned time period.
Which two actions can an administrator take to share the dashboard and accomplish these requirements? (Choose two.)
A company has a number of vSphere clusters where it runs business-critical workloads. Company policy states that to ensure adequate resources, the clusters should never have greater than a 4:1 virtual to physical CPU ratio and a 1:1 virtual to physical memory ratio.
Which capacity model should be configured for those clusters in vRealize Operations?
Answer : A
According to the VMware vRealize Operations Reference Materials, the allocation model is a capacity model that allows you to define the overcommit ratios for CPU and memory resources for your clusters. The allocation model helps you to avoid overcommitment for business-critical workloads and to comply with contractual obligations or SLAs. The allocation model calculates the capacity based on the configured overcommit ratios and the reserved capacity for the clusters. In this case, the company policy states that the clusters should never have greater than a 4:1 virtual to physical CPU ratio and a 1:1 virtual to physical memory ratio. Therefore, the allocation model should be configured for those clusters in vRealize Operations with the same overcommit ratios. This way, the capacity analytics will reflect the company policy and help to plan for infrastructure procurement or migrations based on the projection and avoid the risk of capacity shortage and high infrastructure costs. Therefore, option A is correct.
The other options are not correct because they are not capacity models that can be configured for the clusters in vRealize Operations. Option B is not correct because the demand model is a capacity model that calculates the capacity based on the actual demand for resources in the clusters. The demand model does not consider the overcommit ratios or the reserved capacity for the clusters. The demand model aims to drive towards the most efficient utilization of the clusters based on the historical utilization and the projected utilization. Option C is not correct because the limit model is not a term used in vRealize Operations, but in vSphere. The limit model is a setting that specifies the upper limit of resources that can be consumed by a virtual machine. Option D is not correct because the reservation model is not a term used in vRealize Operations, but in vSphere. The reservation model is a setting that specifies the minimum amount of resources that are guaranteed to a virtual machine.References:

A company is consuming services from multiple public clouds, and the administrator has been asked to configure vRealize Operations Manager to monitor all supported environments.
Which two Cloud Accounts may be used? (Choose two.)
Answer : A, B
Google Cloud, Alibaba Cloud, and IBM Cloud are also popular public cloud providers that offer various cloud services, but they are not supported as Cloud Accounts in vRealize Operations Manager. Therefore, they cannot be used to monitor the environments in vRealize Operations Manager. To monitor these cloud platforms, the administrator might need to use other tools or methods, such as third-party management packs, custom integrations, or external APIs .References:
