Dma — Microsoft Azure Administrator (AZ-104) Practice Questions

Direct Memory Access (DMA) is a hardware capability that allows peripherals to transfer data directly to and from system memory without involving the CPU for each operation. In the AZ-104 context, DMA awareness surfaces when configuring Azure virtual machines with high-performance workloads, GPU-enabled VM sizes, or InfiniBand-connected HPC clusters where DMA-capable network adapters are used. Administrators must understand how Azure Accelerated Networking leverages DMA-based SR-IOV to bypass the hypervisor and deliver low-latency, high-throughput networking to supported VM sizes.
