Prepare for the NVIDIA-Certified Associate: Generative AI and LLMs (NCA-GENL) exam — an entry-level, 50-question, 60-minute credential validating the foundations of building LLM-powered applications with NVIDIA. Covers machine-learning and neural-network fundamentals (transformers and attention), prompt engineering, alignment (instruction tuning, RLHF, PEFT/LoRA), retrieval-augmented generation, data preprocessing and experimentation, the Python and RAPIDS/cuDF tooling used with LLMs, and the NVIDIA stack for building and deploying models — NeMo, NIM, Triton, and TensorRT — plus trustworthy AI and guardrails. Includes a knowledge check per lesson, a mastery check per domain, a full-length mock exam, and a spaced-repetition flashcard deck.
