Question 7
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.)
Assign a custom memory share value to the resource pool containing the Production VMs.
Assign a memory reservation value to the resource pool containing the Production VMs.
Create a parent resource pool for the Production VMs.
Create a sibling resource pool for each of the Production and Test VMs.
Create a child resource pool for the Test VMs.
Correct answer: BE
Explanation:
Option B and E are correct because they allow the administrator to create resource pools for the Production and Test VMs and assign memory reservation values to the Production resource pool, which guarantees that the Production VMs are always allocated their full memory. Option A is incorrect because assigning a custom memory share value to the Production resource pool does not guarantee that the Production VMs are always allocated their full memory, but only gives them higher priority when there is contention. Option C is incorrect because creating a parent resource pool for the Production VMs does not change anything unless there are child resource pools under it. Option D is incorrect because creating a sibling resource pool for each of the Production and Test VMs does not change anything unless there are different resource settings for each pool.
