Answer : B

Deep learning, a subset of machine learning, relies on large datasets to train multi-layered neural networks, enabling them to learn hierarchical feature representations and complex patterns autonomously. While machine learning encompasses broader techniques (some requiring less data), deep learning's dependence on vast data volumes distinguishes it. Inferencing, the application of trained models, typically uses smaller, real-time inputs rather than extensive training data.

Answer : D

NVIDIA GPUDirect Storage enables direct data paths between GPU memory and local or remote storage (e.g., NVMe over fabrics), bypassing the CPU and host memory. This maximizes throughput and minimizes latency in AI data pipelines. NVLink connects GPUs, GPUDirect P2P facilitates GPU-to-GPU transfers, and InfiniBand is a network fabric, but only GPUDirect Storage targets storage access.

Answer : D

InfiniBand is renowned for three key features: low latency (microsecond-scale communication), high bandwidth (100 Gb/s and beyond), and CPU offloads (via RDMA), which shift data transfer tasks to the network hardware, boosting system efficiency. High latency contradicts InfiniBand's design, and GPU offloads are not a core networking feature, making low latency, high bandwidth, and CPU offloads the definitive trio.

Answer : D

A Data Processing Unit (DPU) is a programmable processor that offloads, accelerates, and isolates infrastructure workloads---like networking, storage, and security---from the CPU. This enhances performance, reduces CPU overhead, and improves security by segregating tasks, benefiting AI data centers. It doesn't handle backups or physical infrastructure directly, focusing instead on compute efficiency.

Answer : C

Deep learning breakthroughs stem from three pillars: advances in hardware (e.g., GPUs and TPUs) providing the compute power for large-scale neural networks; the availability of large datasets offering the data volume needed for training; and improvements in training algorithms (e.g., optimizers like Adam, novel architectures like Transformers) enhancing model efficiency and accuracy. While internet speed, sensors, or smartphones play roles in broader tech, they're less directly tied to deep learning's core advancements.
