FlexCache software supports cache access for which types of clients?

FlexCache software is designed to enhance data access performance by providing a cached view of data across distributed environments. It specifically supports caching for client access via NFS (Network File System) version 3 and SMB (Server Message Block).

NFSv3 is widely used in Unix/Linux environments for file sharing, and SMB is commonly leveraged in Windows environments. By enabling these protocols, FlexCache allows clients to benefit from reduced latency and improved data access speeds, making it suitable for scenarios where multiple clients require frequent access to the same data sets.

The other options suggested protocols that are not supported by FlexCache for cache access. FTP (File Transfer Protocol) and HTTP (HyperText Transfer Protocol) are primarily used for file transfers and web communications, which do not align with the caching capabilities provided by FlexCache. Similarly, SFTP (Secure File Transfer Protocol) and AFP (Apple Filing Protocol) are also not part of the supported protocols for FlexCache, limiting their applicability in this context. Therefore, the capability of FlexCache to support access only through NFSv3 and SMB is why this answer is correct.
