The two steps the cloud administrator can take to troubleshoot this issue are: D. Log in to the VMware ESXi host using SSH and run 'esxtop' to examine CPU statistics, and E. Use the VMware vSphere Client to connect to the VMware vCenter which manages the virtual machine and examine its performance statistics. By using the 'esxtop' command, the administrator can view real-time CPU statistics and look for any anomalies that may be causing the performance issues. Additionally, by connecting to the VMware vCenter, the administrator can look at performance statistics and graphs to identify any potential problems.

VMware vSAN is a distributed storage platform that is integrated into the VMware Cloud software-defined data center (SDDC). It provides policy-based storage management, allowing cloud administrators to define storage policies that can be applied to virtual machines and other workloads. These policies govern how data is stored, replicated, and secured, and are used to ensure that data is stored in a consistent and compliant manner.

The statement that most accurately describes the service features of VMware Cloud on Dell EMC is C. An SDDC includes a minimum of one rack with three hosts. You can add hosts to the rack, up to the maximum supported by the rack. An SDDC consists of a rack with a minimum of three hosts, which can then be expanded up to the maximum supported by the rack. VMware Site Recovery is not included as part of the initial service offering.
VMware Cloud on Dell EMC provides a service that enables customers to run their VMware-based workloads on Dell EMC's hardware, in a jointly-engineered and fully-supported environment. The service allows customers to deploy a fully-configured VMware SDDC on Dell EMC VxRail or VxRack SDDC systems, with the option to add more hosts to the rack as needed.
