WebOct 19, 2015 · The MongoDB documentation (bit.ly/1SxKrYI) clearly states a fault-tolerance per replica set size. Only one node can fail in a replica set of three nodes. In a set of five nodes, two is the maximum number of nodes that can fail without the whole cluster going down, as shown in Figure 5. Figure 5 MongoDB Replica Set Fault Tolerance WebThis type of fault tolerance compensates for a failed power supply: a. Hardware fault tolerance b. Software fault tolerance c. System fault tolerance d. Dynamic fault tolerance. A. This is an example of hardware fault tolerance: a. Redundant hard drives in the server b. Multiple-version programs c.
