Exam Overview
The NVIDIA-Certified Associate: Generative AI Multimodal (NCA-GENM) is an entry-level credential that validates foundational competencies in designing, implementing, and managing AI systems capable of processing and generating data across multiple modalities — specifically text, images, and audio. The exam covers seven knowledge domains: Experimentation, Core ML/AI Knowledge, Multimodal Data, Software Development, Data Analysis & Visualization, Performance Optimization, and Trustworthy AI. Candidates are assessed on their ability to apply these concepts in practical, real-world scenarios involving multimodal generative AI systems.
This certification is part of NVIDIA's broader certification portfolio offered through its Deep Learning Institute (DLI). It is priced at $125 and valid for two years from issuance, after which recertification requires retaking the exam. Upon passing, candidates receive a digital badge and an optional certificate. The NCA-GENM is distinct from the companion NCA-GENL (Large Language Models) certification in that it emphasizes multimodal architectures — including diffusion models, image synthesis, conversational AI, and digital avatar development — rather than focusing solely on text-based LLMs.
Who Should Take This Exam
The NCA-GENM is designed for professionals across a wide range of AI and software roles who work with or aspire to work with multimodal generative AI systems. NVIDIA identifies at least 13 relevant professional roles, including machine learning engineers, data scientists, AI DevOps engineers, software engineers, cloud solution architects, LLM specialists, and AI strategists. It is equally suitable for career changers and self-taught practitioners since the certification validates applied skills rather than academic credentials.
Candidates who benefit most are those seeking to formalize their understanding of multimodal AI — particularly professionals transitioning into roles that involve building or deploying systems combining vision, audio, and language models. Those already holding the NCA-GENL certification may pursue NCA-GENM to complement their LLM expertise with multimodal capabilities.
Prerequisites
There are no formal prerequisites required to register for the NCA-GENM exam. NVIDIA recommends that candidates have a basic understanding of generative AI concepts before attempting the exam. Familiarity with Python programming or algorithmic thinking is also beneficial, as the exam covers software development and implementation practices.
NVIDIA recommends completing approximately 30 hours of preparatory coursework through its Deep Learning Institute, available in both self-paced and instructor-led formats. Recommended topics include deep learning fundamentals, transformer-based NLP, conversational AI, diffusion models, and multimodal AI agents. While these courses are not mandatory, they directly align with the exam's domain structure and are the primary preparation pathway endorsed by NVIDIA.
Exam Format
The NCA-GENM exam consists of 50 to 60 multiple-choice questions and must be completed within a 60-minute time limit. The exam is delivered online and is remotely proctored, meaning candidates can take it from any location with a stable internet connection. The exam is currently offered in English only and costs $125 to register.
NVIDIA does not publicly publish a specific numerical passing score. Candidates who achieve a passing result receive a digital badge and an optional printed certificate indicating the certification level and subject area. The certification remains valid for two years from the date of issuance, and recertification is accomplished by retaking the exam — there is no separate renewal pathway.

Compared to general cloud provider AI certifications, NCA-GENM is more narrowly focused on generative and multimodal AI, making it a strong differentiator for practitioners specifically targeting generative AI roles.
Sample Questions
5 sample questions with answers and explanations. The full bank has 792 questions, enough for 12 full-length practice exams.
Preview — answers shown1. A machine learning infrastructure team is deploying a 70B parameter LLM using Triton Inference Server with the TensorRT-LLM backend. They need to configure the batching strategy to maximize throughput by adding new inference requests at each token generation step rather than waiting for entire batches to complete. Which parameter configuration should they use in the Triton model config.pbtxt? (Select one!)
Abatching_strategy: static_batching with max_queue_delay_microseconds: 0
Bbatching_strategy: dynamic_batching with preserve_ordering: true
Cbatching_strategy: continuous_batching with sequence_batching enabled
Dbatching_strategy: inflight_fused_batching with decoupled: true
Explanation
Inflight fused batching is the TensorRT-LLM batching strategy that adds new requests at each token generation step, maximizing GPU utilization by reusing batch slots as they become free. The decoupled flag must be set to true to enable streaming responses required for this batching mode. Static batching forces all requests to wait for the longest sequence. Dynamic batching in Triton is designed for traditional models, not autoregressive LLM generation. Continuous batching is terminology used by other frameworks like vLLM, but TensorRT-LLM specifically uses inflight_fused_batching.
2. A data science team is implementing multimodal RAG for a technical documentation system that includes text documents, architecture diagrams, and flowcharts. The retrieval system must efficiently match user queries against both text content and visual information in diagrams. The team wants to use a unified embedding approach rather than maintaining separate vector stores for each modality. Which architectural approach should the team implement? (Select one!)
AUse CLIP to encode both text queries and images into a shared vector space for unified retrieval
BImplement separate Faiss vector stores for text and images with a weighted fusion layer
CConvert all images to text descriptions using OCR during preprocessing, then use text-only embeddings
DUse separate BERT embeddings for text and ResNet embeddings for images with a cross-modal reranker
Explanation
CLIP is specifically designed for unified embedding of text and images into a shared vector space through contrastive learning, making it ideal for multimodal RAG where queries need to match against both text and visual content. Both the text encoder and vision encoder produce embeddings in the same 512-dimensional space, enabling direct similarity comparison between text queries and image content without separate stores or reranking stages. Using separate BERT and ResNet embeddings requires maintaining separate embedding spaces and a cross-modal reranker, adding complexity and not providing the unified approach requested. Converting images to text via OCR loses visual information present in diagrams, flowcharts, and architecture visuals that cannot be fully captured through text descriptions alone, defeating the purpose of multimodal RAG. Implementing separate Faiss stores for text and images is explicitly the opposite of the requested unified embedding approach and requires complex weighted fusion logic to combine results from different modality-specific stores.
3. A generative AI team is building a text-to-image pipeline using Stable Diffusion. During the denoising process, the U-Net must incorporate text prompt information to guide image generation toward the desired content. The text encoder produces 77 token embeddings with 768 dimensions from the input prompt. Through which architectural mechanism does the U-Net integrate these text embeddings to condition the image generation process? (Select one!)
ACross-attention layers allow spatial features to query text token embeddings throughout the U-Net
BText embeddings are concatenated with the noisy latent tensor at the U-Net input layer
CText embeddings directly replace the predicted noise at each denoising timestep
DText embeddings are encoded into the VAE latent space before diffusion processing begins
Explanation
Stable Diffusion uses cross-attention layers distributed throughout the U-Net architecture to condition image generation on text. In cross-attention, the spatial features from the image (queries) attend to the text token embeddings (keys and values), allowing each spatial location in the feature map to focus on relevant parts of the text prompt. This mechanism enables fine-grained control where different image regions are influenced by different prompt tokens. Concatenating text to the input latent would not provide the spatial-to-textual alignment needed for detailed control. Text embeddings do not replace noise predictions; the U-Net predicts noise while being guided by text via cross-attention. Text embeddings are not encoded into VAE latent space; the VAE operates on images only, while text conditioning happens within the U-Net denoising process.
4. A cloud service provider is configuring NVIDIA H100 GPUs to support multiple isolated customer workloads using Multi-Instance GPU (MIG) partitioning. Each customer requires guaranteed GPU resources with fault isolation. An administrator needs to list all available MIG GPU instances and their configurations on the system before creating partitions for customers. Which nvidia-smi command should they use? (Select one!)
Anvidia-smi mig --list-gpu-instances
Bnvidia-smi mig -lgi
Cnvidia-smi -q -d MIG
Dnvidia-smi --list-mig-instances
Explanation
The correct command to list MIG GPU instances is nvidia-smi mig -lgi (list GPU instances). This displays all configured MIG instances on the system with their profiles and resource allocations. The nvidia-smi MIG commands use the subcommand syntax with short flags. While --list-mig-instances appears intuitive, it is not a valid nvidia-smi flag. The command nvidia-smi -q -d MIG queries detailed MIG information but is more verbose than necessary for simply listing instances. The command nvidia-smi mig --list-gpu-instances uses incorrect long-form flag syntax; the mig subcommand uses -lgi, not --list-gpu-instances.
5. A machine learning engineer is comparing quantization methods for deploying a 70B parameter language model on NVIDIA H100 GPUs. The deployment scenario involves serving multiple concurrent users with batch sizes typically ranging from 24 to 48 requests. The engineer wants to select the quantization method that provides the best balance of throughput, latency, and accuracy for this high-throughput scenario. Which quantization method should be selected? (Select one!)
AINT4 AWQ weight-only quantization for maximum memory savings
BFP8 quantization for optimal performance on Hopper architecture
CGPTQ 4-bit quantization for general compression
DSmoothQuant INT8 for maximum inference speedup
Explanation
FP8 quantization is optimal for H100 Hopper architecture with large batch sizes (24-48 requests), providing the best balance of performance and accuracy. FP8 leverages Hopper's fourth-generation Tensor Cores and Transformer Engine, delivering approximately 2x speedup over FP16 with minimal accuracy degradation and no calibration required. For batch sizes of 16 or greater, FP8 is the recommended choice. INT4 AWQ weight-only quantization is best suited for memory-limited scenarios and small batch sizes of 4 or fewer, where memory bandwidth rather than compute is the bottleneck. With batch sizes of 24-48, compute becomes more important, making FP8 more effective. SmoothQuant INT8 can provide good speedup but FP8 on H100 typically achieves better performance due to hardware-specific optimizations for FP8 operations. GPTQ 4-bit provides strong compression but is primarily designed for weight-only quantization scenarios and does not fully leverage H100's advanced FP8 Tensor Core capabilities.
