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.

Preview — answers shown1. A computer vision team is optimizing a custom CUDA kernel for image preprocessing on NVIDIA Ampere A100 GPUs. The kernel processes NCHW format tensors for a classification model using Tensor Cores. After profiling, they observe suboptimal Tensor Core utilization despite the A100 supporting the required precision. Which tensor format change and dimension alignment strategy will maximize Tensor Core performance? (Select one!)
AConvert tensors from NCHW to NHWC channels-last format with dimensions aligned to multiples of 8 for FP16
BUse NCHW format with dimensions aligned to multiples of 16 for INT8 quantized operations
CImplement custom NCHW tensor layout optimized for Ampere cache hierarchy
DKeep NCHW format but add automatic transposition layer before Tensor Core operations
Explanation
NHWC channels-last tensor format is optimal for Tensor Core performance as it enables efficient data access patterns for matrix operations. Dimensions should be aligned to multiples of 8 for FP16 operations on Tensor Cores. This combination eliminates the transpose overhead and maximizes Tensor Core throughput on Ampere. NCHW format requires transposition before Tensor Core operations, adding overhead. While dimensions aligned to 16 for INT8 is correct for that precision, NHWC format would still be superior. Custom NCHW layouts cannot match the native efficiency of NHWC for Tensor Core operations regardless of cache optimization.
2. A GPU compute cluster administrator needs to monitor NVIDIA GPU utilization, memory usage, and power consumption across a fleet of 128 H100 GPUs in real-time. They want to export metrics to a monitoring dashboard that updates every 2 seconds. The solution must minimize CPU overhead and support automated alerting when GPU memory exceeds 90 percent. Which approach should they implement?
AEnable persistence mode with nvidia-smi -pm 1 and query GPU metrics via NVML API programmatically
BRun nvidia-smi in loop mode with 2-second interval and parse CSV output for metrics collection
CConfigure MIG mode to partition GPUs and monitor each instance separately with dcgm-exporter
DUse nvidia-smi --query-gpu with custom queries and export to Prometheus for dashboard integration
Explanation
Enabling persistence mode with nvidia-smi -pm 1 keeps the NVIDIA driver loaded, reducing latency for metric queries. Using the NVML (NVIDIA Management Library) API programmatically allows efficient real-time polling at 2-second intervals with minimal CPU overhead and enables automated threshold-based alerting when memory exceeds 90 percent. Running nvidia-smi in a loop creates process overhead for each invocation and parsing CSV output is inefficient compared to native API access. While nvidia-smi can query specific metrics and export formats, it does not directly integrate with Prometheus without additional tooling like dcgm-exporter or custom exporters. MIG mode is for partitioning GPUs into isolated instances for multi-tenancy, not for monitoring existing full-GPU workloads, and dcgm-exporter is typically used with DCGM (Data Center GPU Manager) for Kubernetes environments with specific metric export requirements.
3. A remote collaboration platform is integrating NVIDIA Maxine Audio Effects SDK to improve audio quality for users working from home. The platform must address three specific issues: background noise from pets and household activities, echo caused by sound reflecting off walls in unfurnished rooms, and feedback loops when users have both speakers and microphones active. The solution must run on consumer RTX 3070 GPUs. Which Maxine audio effects combination addresses all three problems? (Select three!)
Multiple correct answersANoise Removal effect for suppressing household background sounds
BSuper Resolution effect for enhancing audio clarity
CRoom Echo Removal (Dereverb) for eliminating wall reflections
DAcoustic Echo Cancellation for preventing speaker-to-microphone feedback
EAI Upscaling for improving compressed audio quality
FStudio Voice for professional sound enhancement
Explanation
Noise Removal eliminates background noise from pets and household activities by distinguishing speech from 25+ noise types using AI. Room Echo Removal (Dereverb) processes reverberant audio to remove echoes caused by sound reflecting off hard surfaces like walls. Acoustic Echo Cancellation specifically prevents the speaker output from being captured by the microphone, eliminating feedback loops. All three effects run efficiently on RTX 3070 Tensor Cores. Super Resolution is a video effect for upscaling images, not audio processing. AI Upscaling is not a Maxine audio effect. Studio Voice is a general enhancement feature but does not specifically address the three technical issues described.
4. An autonomous vehicle team is building a sensor fusion system that processes synchronized LiDAR point clouds and camera images. The system must identify precise spatial correspondences between 3D objects detected in LiDAR and their visual appearance in camera feeds across multiple timestamps. The team is evaluating different multimodal fusion architectures. Which fusion approach best captures the spatial and temporal alignment between LiDAR geometry and visual features? (Select one!)
AEarly fusion by concatenating raw LiDAR voxel grids and camera image tensors at the input layer before any feature extraction
BEarly fusion with separate encoder networks for each modality followed by channel-wise concatenation and joint processing
CHybrid fusion with cross-attention mechanisms in intermediate layers that learn dynamic correspondences between 3D and visual features
DLate fusion by running independent object detection models on each modality and merging bounding box predictions at the output
Explanation
Hybrid fusion with cross-attention mechanisms in intermediate network layers is optimal for learning spatial and temporal correspondences between LiDAR 3D geometry and camera visual features. Cross-attention allows the model to dynamically learn which visual features correspond to which 3D spatial features at each time step, effectively modeling the geometric relationships between modalities. This approach processes each modality through initial layers to extract domain-specific features, then uses cross-attention to identify correspondences. Early fusion by concatenating raw inputs struggles with modality heterogeneity (LiDAR point clouds vs images have fundamentally different structures) and cannot effectively learn geometric correspondences without sophisticated architectures. Late fusion processes each modality completely independently and only combines final predictions, missing all cross-modal geometric interactions during feature learning. Early fusion with separate encoders followed by concatenation creates a fixed fusion point without the dynamic weighting needed to model complex spatial-temporal correspondences across different sensor geometries.
5. A computer vision team is optimizing a YOLOv8 object detection model for deployment on NVIDIA L4 GPUs using TensorRT. The model must handle dynamic input sizes ranging from 640x640 to 1280x1280 pixels for different camera resolutions. They need to build a TensorRT engine with optimal performance for the most common input size of 1024x1024. Which trtexec command correctly configures dynamic shapes for this deployment? (Select one!)
Atrtexec --onnx=yolov8.onnx --saveEngine=yolov8.plan --dynamicShapes=input:640-1280 --fp16
Btrtexec --onnx=yolov8.onnx --saveEngine=yolov8.plan --minShapes=input:1x3x640x640 --optShapes=input:1x3x1024x1024 --maxShapes=input:1x3x1280x1280 --fp16
Ctrtexec --onnx=yolov8.onnx --saveEngine=yolov8.plan --shapes=input:1x3x640x640,input:1x3x1280x1280 --fp16
Dtrtexec --onnx=yolov8.onnx --saveEngine=yolov8.plan --inputShapes=1x3x1024x1024 --allowDynamic --fp16
Explanation
TensorRT dynamic shape configuration requires three parameters: minShapes for minimum dimensions, optShapes for the optimization target, and maxShapes for maximum dimensions. The correct syntax specifies all four dimensions (batch, channels, height, width) for each profile. Setting optShapes to 1x3x1024x1024 ensures TensorRT optimizes performance for the most common input size. The --shapes parameter does not support dynamic ranges and would fail. The --dynamicShapes parameter with range syntax is not valid trtexec syntax. The --inputShapes parameter with --allowDynamic flag is not the correct approach; TensorRT requires explicit min/opt/max shape profiles.
