After an administrator deployed a private cloud a couple of years ago, users have started reporting that the network is getting slower. The administrator looks at the monitoring tools and notices that, even though supernetting was used to allow for 8,000 more VMs, the most utilized switch port in the datacenter is only using 40% of its total throughput speed. Which of the following is MOST likely the problem?

A.
The number of VMs using 1Pv4 is causing the network to crash.

B.
Each host only has two links to the network, and they are becoming saturated.

C.
The network only has 4Gbps HBAs when all cloud networks should be using 10Gbps.

D.
There are too many devices broadcasting on the subnet.
