A vSphere cluster has the following configuration:

$$ Virtual machines $($VMs$)$ are running Production and Test workloads vSphere Distributed Resource

$$ Scheduler $($DRS$)$ is enabled

$$ There are no resource pools in the cluster

$$ Performance monitoring data shows that the Production workload VMs are not receiving their fully allocated memory when the vSphere cluster is fully utilized.

A combination of which TWO steps could the administrator perform to ensure that the Production VMs are always guaranteed the full allocation of memory? $($Choose two.$)$

A$.$ Assign a custom memory share value to the resource pool containing the Production VMs$.$

B$.$ Assign a memory reservation value to the resource pool containing the Production VMs$.$

C$.$ Create a parent resource pool for the Production VMs$.$

D$.$ Create a sibling resource pool for each of the Production and Test VMs$.$

E$.$ Create a child resource pool for the Test VMs$.$
