What are two methods of maximizing VMFS performance for virtual machines across all the hosts
in a cluster? (Choose two.)

Use disk shares to prioritize virtual machine disk I/O
B.
Enable Storage I/O control
C.
Enable Storage DRS with I/O load balancing
D.
Enable Host Cache using local SSD drives
Explanation:
To maximize VMFS performance of virtual machines, you can enable Storage I/O control and
