What are two ways vsphere cluster, enabled with high availability HA and distributed resource scheduler DRS , differs from traditional failover solution? (Choose two)

A vSphere HA cluster provides automated failover support for all virtual machines within the cluster without requiring specific agents or software to be installed inside each VM's guest operating system, which is a common requirement for many traditional failover solutions.

vSphere HA operates at the hypervisor level and does not require special software or drivers to be installed within the application or the virtual machine's guest operating system for its basic failover functionality.

If a host fails, vSphere HA restarts the virtual machines, but vSphere DRS adds continuous optimization by migrating virtual machines using vMotion to balance resource utilization and optimize performance across the cluster, even reacting to increased workloads, which goes beyond basic traditional failover functionality.

vSphere HA protects virtual machines within a cluster, requiring at least two ESXi hosts and shared storage for failover; it does not protect the availability of virtual machines installed on a standalone ESXi host.
