The Question was: An administrator set up the following configuration: The distributed switch has four ESXi hosts, and each host has two 10 Gbps NICs. In the Network I/O Control configuration, the amount of bandwidth reserved for virtual machine (VM) traffic is 4 Gbps. The administrator wants to guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic. You have 4 ESXis. Each has ESXi has 2 vmnics. Each nic has 10G.

To guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic, the administrator should create a network resource pool for the Retail distributed port group and allocate 50 percent of the reserved bandwidth for VM traffic to it. Given that there are four ESXi hosts, each with two 10 Gbps NICs, the total available bandwidth is 80 Gbps (4 hosts x 2 NICs per host x 10 Gbps per NIC). The amount of bandwidth reserved for VM traffic is 4 Gbps. To allocate 50 percent of the reserved bandwidth for VM traffic to the Retail distributed port group, the administrator should create a network resource pool for the Retail distributed port group with a size of 2 Gbps (50 percent of 4 Gbps) and associate it with the distributed switch. Therefore, the correct answer is: 8 The size of the Retail network resource pool should be 8 Gbps to guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic

Then 36Gbps *50% = 18 Gbps A.
