Final answer:
HA and DRS are compatible features of VMware vSphere that can be used together, with HA providing high availability through failover capabilities and DRS optimizing workload distribution across hosts in a cluster.
Step-by-step explanation:
The statement that HA (High Availability) and DRS (Distributed Resource Scheduler) cannot be used together is false. Both HA and DRS are features provided by VMware vSphere, and they are not only compatible but also often used together to provide a more robust and efficient virtualized environment.
High Availability ensures that in the event of a server failure, the virtual machines on that server are restarted or continued on other servers within the cluster without significant downtime. On the other hand, Distributed Resource Scheduler assists in balancing workloads across various hosts in a cluster to optimize performance.
When combined, HA and DRS can handle both failover scenarios and resource distribution, ensuring that the user experience is both seamless and efficient. These functionalities provide a level of resiliency and automation that are critical for modern virtualized data centers.
