You are planning a Hadoop cluster and considering implementing 10 Gigabit Ethernet as the network fabric. Which workloads benefit the most from faster network fabric?

The correct answer is D. When your workload generates a large amount of intermediate data, on the order of the input. "When we encounter applications that produce large amounts of intermediate data - outputting data on the same order as the amount read in - we recommend two ports on a single Ethernet card or two channel-bonded Ethernet cards to provide 2 Gbps per machine."
