What are three goals of resource management within a cluster? (Choose three.)
The correct answer is A. To prevent virtual machines from monopolizing resources and to guarantee predictable service B. To exploit undercommitted resources and overcommit with graceful degradation. D. To control the relative importance of virtual machines and provide flexible dynamic partitioning. vSphere cluster resource management goals center on preventing resource monopolization, exploiting available capacity through overcommitment, and controlling the relative priority of virtual machines.

Why each option
vSphere cluster resource management goals center on preventing resource monopolization, exploiting available capacity through overcommitment, and controlling the relative priority of virtual machines.
Preventing any single VM from monopolizing cluster resources and guaranteeing predictable service levels through reservations and limits is a foundational resource management goal, ensuring all VMs reliably receive the compute capacity they require.
Exploiting undercommitted resources by allowing overcommitment - while maintaining graceful degradation under contention - is a key goal that maximizes hardware utilization without causing hard failures when aggregate demand temporarily exceeds physical supply.
Providing solutions to problems encountered when using vCenter Server is a general troubleshooting or support objective, not a resource management goal - resource management focuses on compute allocation policy, not vCenter operational issues.
Controlling the relative importance of VMs through shares and providing flexible dynamic partitioning via resource pools allows administrators to allocate and rebalance compute resources proportionally across workloads as demand fluctuates.
Network administration capabilities such as distributed switch configuration and port group management are handled by vSphere networking subsystems, not by the cluster resource management framework.
