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 medical transcription company is deploying NVIDIA Riva for automatic speech recognition to transcribe doctor-patient consultations. They need accurate recognition of medical terminology including drug names, anatomical terms, and procedure names that are frequently misrecognized by the base ASR model. The deployment uses a Conformer-CTC acoustic model. Which two configuration requirements must be met to enable word boosting for these specialized medical terms in NVIDIA Riva? (Select two!)
Multiple correct answersAConfigure the ASR service to use Flashlight decoder instead of greedy decoder
BSwitch to a Whisper-based model which supports medical term boosting
CAdd medical terms to SpeechContext objects with boost values between 20 and 100
DEnable lexicon-free decoding mode for faster inference
EUse Parakeet multilingual models which have built-in medical vocabulary
Explanation
Word boosting in NVIDIA Riva requires two key configurations: using the Flashlight decoder instead of greedy decoder, and configuring SpeechContext objects with the specialized terms and boost values typically ranging from 20 to 100. The Flashlight decoder is required because it inspects multiple hypotheses and uses language model scores in conjunction with acoustic model scores to weight these hypotheses, enabling word boosting. The greedy decoder does not support word boosting. SpeechContext allows you to bias the ASR engine to recognize particular words by giving them higher scores during decoding. Whisper models do not support word boosting according to NVIDIA Riva documentation. Lexicon-free decoding mode is incorrect as word boosting requires lexicon-decoding mode with a language model. Parakeet multilingual models also do not support word boosting features.
2. A machine learning team is deploying a conversational AI model using TensorRT-LLM backend with Triton Inference Server. They need to support streaming responses where tokens are returned as they are generated rather than waiting for complete sequences. The model will serve multiple concurrent users with varying request lengths. Which two configuration parameters must be set in the Triton model config.pbtxt file to enable streaming with dynamic request handling? (Select two!)
Multiple correct answersASet model_transaction_policy with decoupled: true
BSet batching_strategy to inflight_fused_batching
CSet instance_group kind to KIND_CPU
DSet dynamic_batching preserve_ordering to false
ESet backend to pytorch
Explanation
Setting model_transaction_policy with decoupled true enables streaming responses in TensorRT-LLM, allowing tokens to be returned incrementally rather than waiting for completion. Setting batching_strategy to inflight_fused_batching allows new requests to be added to batches at each token generation step, optimizing throughput for concurrent users with varying request lengths. This combination provides both streaming capability and efficient dynamic batching. Setting instance_group to KIND_CPU would use CPU instead of GPU, drastically reducing performance. Setting preserve_ordering to false is unrelated to streaming enablement. Using pytorch backend instead of tensorrtllm would bypass TensorRT-LLM optimizations entirely.
3. A research team is implementing a vision-language model for visual question answering about technical diagrams. They are comparing different VLM architectures and need to understand the role of the projector component. The projector must transform vision encoder outputs to be compatible with the language model's input space. Which architectural approach does BLIP-2 use for its projector component? (Select one!)
AGated cross-attention layers
BSimple linear MLP projection layer
CPerceiver Resampler with cross-attention
DQ-Former with learned queries
Explanation
BLIP-2 uses a Q-Former (Query Transformer) with learned queries as its projector component. The Q-Former is a lightweight transformer module that uses a set of learnable query tokens to extract visual features from the frozen vision encoder through cross-attention, then outputs a fixed number of query embeddings that serve as input to the frozen LLM. This design allows BLIP-2 to bridge frozen vision and language models efficiently. Simple linear MLP projection is used by LLaVA, not BLIP-2. Perceiver Resampler is the approach used by Flamingo. Gated cross-attention layers are also a Flamingo architectural feature, not BLIP-2.
4. A machine learning platform team is monitoring GPU utilization using nvidia-smi and notices that GPU processes are frequently reinitialized, causing initialization overhead. Which nvidia-smi command should they run to enable persistence mode and reduce initialization latency? (Select one!)
Anvidia-smi -c EXCLUSIVE_PROCESS to set exclusive compute mode
Bnvidia-smi -l 1 to enable continuous monitoring mode
Cnvidia-smi --persistence-mode=ENABLED to activate persistent process management
Dnvidia-smi -pm 1 to enable persistence mode
Explanation
The command nvidia-smi -pm 1 enables persistence mode, which keeps the NVIDIA driver loaded even when no processes are using the GPU, reducing initialization latency for new GPU processes. The flag -pm 1 sets persistence mode on (1=on, 0=off). The command nvidia-smi -l 1 enables loop mode for continuous monitoring every 1 second but does not enable persistence mode. While --persistence-mode=ENABLED might seem logical, the actual nvidia-smi syntax uses the shorter -pm flag, not a long-form flag. The command -c EXCLUSIVE_PROCESS sets the compute mode to exclusive, limiting GPU access to one process at a time, which is unrelated to persistence mode and would actually reduce utilization.
5. An AI research team is analyzing hallucinations in their deployed vision-language model for product description generation. They observe that the model frequently describes objects that do not exist in product images. Which specific hallucination type are they experiencing? (Select one!)
AObject Hallucination where the model describes non-existent objects
BAttribute Hallucination where the model describes incorrect object properties
CRelationship Hallucination where the model describes incorrect spatial relationships
DScene Hallucination where the model misidentifies the overall context
Explanation
Object Hallucination occurs when a vision-language model describes objects that do not exist in the image, which is exactly what the team is observing with non-existent objects in product descriptions. Attribute Hallucination involves describing incorrect properties (like wrong color or size) of objects that actually exist in the image, not describing non-existent objects. Relationship Hallucination involves incorrect spatial relationships or interactions between objects that do exist in the image. Scene Hallucination involves misidentifying the overall context or action in the scene, such as confusing indoor/outdoor or action types, not describing non-existent objects.
