What is the purpose of vSphere Replication?

vSphere Replication is designed specifically to provide disaster recovery capabilities, which is why the chosen answer is correct. It enables the replication of virtual machines from one location to another, ensuring that a copy of the VM is always available in case of a failure at the primary site. This functionality allows businesses to minimize downtime and safeguard their data, making it a critical component of a robust disaster recovery strategy.

The other options relate to different functions within VMware environments. Cloning VMs across hosts refers to creating complete copies of virtual machines for testing or scaling purposes, which is not the specific aim of vSphere Replication. Managing DRS (Distributed Resource Scheduler) rules pertains to workload balancing across hosts in a cluster and ensuring optimal resource allocation, which does not involve replication. Enhancing VM performance focuses on optimizing the operational efficiency of virtual machines, such as improving processing speed or resource utilization, rather than addressing the need for disaster recovery.
