SMB Direct can utilize which protocol to speed up transfers when supported by the network adapter?

• A. Remote Direct Adapter Access (RDAA)
• B. Remote Direct Network Access (RDNA)
• C. Remote Direct Memory Access (RDMA)
• D. Remote Direct File Access (RDFA)

Answer: (C)

SMB Direct speeds transfers by using a remote direct memory access protocol when the network adapter supports it. RDMA, or Remote Direct Memory Access, moves data directly between the memory of two machines with minimal CPU involvement. This bypasses much of the OS networking stack and enables zero-copy data transfer, which reduces latency and increases throughput. When a RDMA-capable NIC is used and properly configured, SMB data can be transferred with greatly reduced CPU overhead, delivering faster file sharing over the network. The other options aren’t established protocols used for this purpose.
