Question 100

Refer to the exhibit.

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 if 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.

Given this scenario, what should the size (in Gbps) of the Retail network resource pool be?

Correct Answer: D

The distributed switch configuration has four ESXi hosts with two 10 Gbps NICs each, totaling eight 10 Gbps NICs. The amount of bandwidth reserved for VM traffic is 4 Gbps. To guarantee that VMs in the Retail distributed port group can access 50 percent of the available reserved bandwidth for VM traffic, you first calculate 50% of the 4 Gbps reserved bandwidth, which is 2 Gbps. Given that there are 8 NICs in total, the correct size of the Retail network resource pool should be calculated as follows: 2 Gbps * 8 NICs = 16 Gbps. Hence, the size of the Retail network resource pool should be 16 Gbps.

4Gbps*8Nic=32Gbps*50%=16Gbps

"...50 percent of the available reserved bandwidth..." Thats 50% of the 4Gbps reserved = 2Gbps. Multiply by the 4 hosts = 8Gbps

kernelkraut

Just saw my own mistake.... 16Gbps is correct

For anyone reading this in the future, the mistake is that each host has a pair of NICs. So you are multiplying by eight NICs, not four hosts.
