Question 4. Distributed file systems. (20 marks) (a) List and briefly describe five key benefits of a Distributed file system. (b) NFS, CIFS, Hadoop, and NetWare are examples of distributed file sys- tems. Compare and contrast, concerning the performance, fault-tolerance, and replication, two of the examples provided above (for instance NFS vs Hadoop) (c) What is a stateless server? (d) What is the advantage of caching in remote file access? Caching can either be done at a client or in the network (by a proxy server or gateway). Explain the advantages and disadvantages of both strategies
