A.
When the typical workloads generates a large amount of intermediate data, on the order of the
input data itself.

B.
When the typical workloads consists of processor-intensive tasks.

C.
When the typical workloads consumes a large amount of input data, relative to the entire
capacity of HDFS.

D.
When the typical workloads generates a large amount of output data, significantly larger than
the amount of intermediate data.

Explanation:
When we encounter applications that produce large amounts of intermediate
data–on the order of the same amount as is read in–we recommend two ports on a single Ethernet
card or two channel-bonded Ethernet cards to provide 2 Gbps per machine. Alternatively for

customers who have already moved to 10 Gigabit Ethernet or Infiniband, these solutions can be
used to address network bound workloads. Be sure that your operating system and BIOS are
compatible if you’re considering switching to 10 Gigabit Ethernet.
