CCA-410 · Question #31
Under which scenario would it be most appropriate to consider using faster (e.g 10 Gigabit) Ethernet as the network fabric for your Hadoop cluster?
The correct answer is A. When the typical workloads generates a large amount of intermediate data, on the order of the input data itself. 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…
Question
Under which scenario would it be most appropriate to consider using faster (e.g 10 Gigabit) Ethernet as the network fabric for your Hadoop cluster?
Options
- AWhen the typical workloads generates a large amount of intermediate data, on the order of the input data itself.
- BWhen the typical workloads consists of processor-intensive tasks.
- CWhen the typical workloads consumes a large amount of input data, relative to the entire capacity of HDFS.
- DWhen the typical workloads generates a large amount of output data, significantly larger than the amount

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.
