Below is the sample question from MapR Certified Cluster Administrator Study Guide . Can anyone explain why the answer is 800TB. I believe the answer should be A i.e., 640 TB considering default replication factor (3 x 180TB+5x20TB=640TB)
Q9.You are creating a new cluster, and will load 200 TB of non-compressible data into the cluster. 20 TB of the data is considered critical, and will have a replication factor of 5. The rest of the data will use the default replication factor.About how much total cluster storage space should you start with?
