AZ-802 Manage Storage and File Services Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Receive Side Scaling (RSS)

  Why it's wrong here

  Receive Side Scaling (RSS) helps distribute network receive processing across multiple CPU cores to prevent a single core from becoming a bottleneck. While beneficial for general networking, it is not the technology that enables the zero-copy, direct memory access capabilities provided by SMB Direct and RDMA.

• ✓

  Remote Direct Memory Access (RDMA)

  Why this is correct

  RDMA is the underlying hardware capability required for SMB Direct. It allows data to be moved between the memory of two computers without involving either one's operating system or CPU in the data transfer, resulting in significantly higher throughput and reduced latency for storage-heavy communication.

• ✗

  Virtual Machine Queue (VMQ)

  Why it's wrong here

  Virtual Machine Queue (VMQ) is a hardware virtualization feature that accelerates network traffic for virtual machines by delivering packets directly to the VM's memory. While it improves performance in Hyper-V environments, it does not provide the direct-memory-to-network capabilities defined by the SMB Direct protocol.

• ✗

  Network Teaming (LACP)

  Why it's wrong here

  Network Teaming and LACP provide link aggregation and redundancy by combining multiple physical adapters into a single logical interface. While this increases total bandwidth and provides fault tolerance, it does not enable the advanced RDMA features required for SMB Direct to function on Windows Server.
