Enabling vSphere Features with the Required Component

A.

To enable features such as High Availability (HA), vMotion, and Distributed Resource Scheduler (DRS) in a vSphere environment, you need to have vCenter Server.

vCenter Server is a centralized management platform that provides a single point of control for managing multiple ESXi hosts and their virtual machines. vCenter Server provides a range of features including HA, vMotion, DRS, and many others that are required to build a robust and efficient virtual infrastructure.

High Availability (HA) is a feature that provides protection against hardware failures by automatically restarting virtual machines on other hosts in the event of a host failure. vMotion is a feature that allows live migration of running virtual machines from one host to another without any disruption in service. DRS is a feature that balances the workload across multiple hosts in a cluster to optimize performance and resource utilization.

vSphere Client is a graphical user interface used to connect and manage ESXi hosts, but it cannot enable or configure the advanced features such as HA, vMotion, and DRS.

SAN Storage is not directly related to enabling these features. It provides storage for virtual machines and can be used to create shared storage, but it is not required to enable HA, vMotion, and DRS.

Distributed Switch is also not directly related to enabling these features. It is a centralized virtual switch that provides network connectivity between virtual machines and physical network adapters. While it can enhance the functionality of features like HA, vMotion, and DRS, it is not a required component for enabling them.

In summary, vCenter Server is the required component to enable features such as HA, vMotion, and DRS in a vSphere environment.
