Ans: B
Exp: While data is being written to a node and that node become unresponsive while data is being written. Because of either H/W, network or overloaded node issue. If the failure detector marks a node as down and hinted handoff is enabled in the Cassandra.yaml file, then all the missed writes are atored by coordinator node for a period of time. Hints are stored in local directory on each node for improved replay.
