Answer / ranojyoti chowdhury

•Version 2 and Version 3 use the User Datagram Protocol (UDP) running over an IP network to provide a stateless network connection between the client and server.NFS version 3 (NFSv3) has more features, including variable size file handling and better error reporting.
•Version 3 of NFS started to support files that are larger than 2 gb.
•It was version 3 which started a performance option of async, which we saw earlier, to improve performance.
•NFS version 4 was made for better and ease of access over the internet
•NFS version 4 does not require portmap to run (Which is a vulnerable service)
•The virtual root directory concept, that we have implemented with the help of fsid=0, argument improves security
•NFS version 4 uses TCP bydefault for better reliablity over internet
•NFS Version 4 is capable of using 32KB page size which improves the performance a lot, compared to the default 1024 bytes.
