Correct Answer: A, EElastic DRS (Distributed Resource Scheduler) in a VMware Cloud on AWS environment will add another host to the cluster under the default Baseline policy in two specific situations: first, when there is a failure in an availability zone, which ensures that the workload can be redistributed to maintain availability; second, when storage utilization reaches 80%, to ensure there is sufficient storage capacity available in the cluster. Other metrics such as CPU and memory utilization do not trigger the addition of a host under the default settings.
