Correct answer & explanation
NFSv2: Stateless protocol using UDP, limited to 32-bit file handles
NFS versions evolved from stateless NFSv2 (UDP, 32-bit) to NFSv3 (TCP, 64-bit, async writes) to stateful NFSv4 (compound RPC, security, delegation). Common confusions include attributing v4 features to v2 and v2 limitations to v3.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
NFSv2: Stateless protocol using UDP, limited to 32-bit file handles
Why this is correct
NFSv2 is stateless and originally ran over UDP, with 32-bit file handles limiting file size.
NFSv3: Added TCP support, 64-bit file handles, and asynchronous writes
Why this is correct
NFSv3 introduced TCP for better reliability, 64-bit file handles for larger files, and asynchronous writes for improved performance.
NFSv4: Stateful protocol with compound RPC, security integration, and delegation
Why this is correct
NFSv4 is stateful, uses compound RPC to reduce round trips, integrates security features like Kerberos, and supports delegation.
NFSv2: Introduced compound RPC and stateful operations
Why it's wrong here
Incorrect — compound RPC and stateful operations are features of NFSv4, not NFSv2.
NFSv3: Limited to UDP and 32-bit file handles
Why it's wrong here
Incorrect — NFSv3 added TCP and 64-bit file handles; these limitations belong to NFSv2.
