NVIDIA NCA-AIIO 시험요강:

주제
소개

주제 1

Essential AI knowledge: Exam Weight: This section of the exam measures the skills of IT professionals and covers foundational AI concepts. It includes understanding the NVIDIA software stack, differentiating between AI, machine learning, and deep learning, and comparing training versus inference. Key topics also involve explaining the factors behind AI's rapid adoption, identifying major AI use cases across industries, and describing the purpose of various NVIDIA solutions. The section requires knowledge of the software components in the AI development lifecycle and an ability to contrast GPU and CPU architectures.

주제 2

AI Infrastructure: This section of the exam measures the skills of IT professionals and focuses on the physical and architectural components needed for AI. It involves understanding the process of extracting insights from large datasets through data mining and visualization. Candidates must be able to compare models using statistical metrics and identify data trends. The infrastructure knowledge extends to data center platforms, energy-efficient computing, networking for AI, and the role of technologies like NVIDIA DPUs in transforming data centers.

주제 3

AI Operations: This section of the exam measures the skills of data center operators and encompasses the management of AI environments. It requires describing essentials for AI data center management, monitoring, and cluster orchestration. Key topics include articulating measures for monitoring GPUs, understanding job scheduling, and identifying considerations for virtualizing accelerated infrastructure. The operational knowledge also covers tools for orchestration and the principles of MLOps.

최신 NVIDIA-Certified Associate NCA-AIIO 무료샘플문제 (Q18-Q23):

질문 # 18
Your AI team is deploying a multi-stage pipeline in a Kubernetes-managed GPU cluster, where some jobs are dependent on the completion of others. What is the most efficient way to ensure that these job dependencies are respected during scheduling and execution?

A. Deploy All Jobs Concurrently and Use Pod Anti-Affinity
B. Manually Monitor and Trigger Dependent Jobs
C. Use Kubernetes Jobs with Directed Acyclic Graph (DAG) Scheduling
D. Increase the Priority of Dependent Jobs

정답：C

설명：
Using Kubernetes Jobs with Directed Acyclic Graph (DAG) scheduling is the most efficient way to ensure job dependencies are respected in a multi-stage pipeline on a GPU cluster. Kubernetes Jobs allow you to define tasks that run to completion, and integrating a DAG workflow (e.g., via tools like Argo Workflows or Kubeflow Pipelines) enables you to specify dependencies explicitly. This ensures that dependent jobs only start after their prerequisites finish, automating the process and optimizing resource use on NVIDIA GPUs.
Increasing job priority (A) affects scheduling order but does not enforce dependencies. Deploying all jobs concurrently with pod anti-affinity (C) prevents resource contention but ignores execution order. Manual monitoring (D) is inefficient and error-prone. NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals" recommend DAG-based scheduling for dependency management in Kubernetes GPU clusters.

질문 # 19
A healthcare company is training a large convolutional neural network (CNN) for medical image analysis.
The dataset is enormous, and training is taking longer than expected. The team needs to speed up the training process by distributing the workload across multiple GPUs and nodes. Which of the following NVIDIA solutions will help them achieve optimal performance?

A. NVIDIA NCCL and NVIDIA DALI
B. NVIDIA cuDNN
C. NVIDIA DeepStream SDK
D. NVIDIA TensorRT

정답：A

설명：
Training a large CNN on an enormous dataset across multiple GPUs and nodes requires efficient communication and data handling. NVIDIA NCCL (NVIDIA Collective Communications Library) optimizes inter-GPU and inter-node communication, enabling scalable data and model parallelism, while NVIDIA DALI (Data Loading Library) accelerates data loading and preprocessing on GPUs, reducing I/O bottlenecks.
Together, they speed up training by ensuring GPUs are fully utilized, a strategy central to NVIDIA's DGX systems and multi-node AI workloads.
cuDNN (Option A) accelerates CNN operations but focuses on single-GPU performance, not multi-node distribution. DeepStream SDK (Option C) is tailored for real-time video analytics, not training. TensorRT (Option D) optimizes inference, not training. NCCL and DALI are the optimal NVIDIA solutions for this distributed training scenario.

질문 # 20
Which two software components are directly involved in the life cycle of AI development and deployment, particularly in model training and model serving? (Select two)

A. Prometheus
B. Apache Spark
C. Airflow
D. MLflow
E. Kubeflow

정답：D,E

설명：
MLflow (B) and Kubeflow (E) are directly involved in the AI development and deployment life cycle, particularly for model training and serving. MLflow is an open-source platform for managing the ML lifecycle, including experiment tracking, model training, and deployment, often used with NVIDIA GPUs.
Kubeflow is a Kubernetes-native toolkit for orchestrating AI workflows, supporting training (e.g., via TFJob) and serving (e.g., with Triton), as noted in NVIDIA's "DeepOps" and "AI Infrastructure and Operations Fundamentals." Prometheus (A) is for monitoring, not AI lifecycle tasks. Airflow (C) manages workflows but isn't AI- specific. Apache Spark (D) processes data but isn't focused on model serving. NVIDIA's ecosystem integrates MLflow and Kubeflow for AI workflows.

질문 # 21
A retail company is considering using AI to enhance its operations. They want to improve customer experience, optimize inventory management, and personalize marketing campaigns. Which AI use case would be most impactful in achieving these goals?

A. AI-powered recommendation systems, which personalize product suggestions for customers based on their behavior
B. Natural language processing for automated customer support chatbots
C. Image recognition for automatic labeling of products in warehouses
D. AI-driven fraud detection to prevent unauthorized transactions

정답：A

설명：
AI-powered recommendation systems are the most impactful use case for improving customer experience, optimizing inventory, and personalizing marketing in retail. These systems, accelerated by NVIDIA GPUs and deployed via Triton Inference Server, analyze customer behavior to deliver tailored suggestions, driving sales, reducing overstock, and enhancing campaigns. NVIDIA's "State of AI in Retail and CPG" report highlights recommendation systems as a top retail AI application.
NLP chatbots (B) improve support but don't address inventory or marketing directly. Fraud detection (C) is security-focused, not operational. Image recognition (D) aids warehousing but lacks broad impact. NVIDIA prioritizes recommendations for retail goals.

질문 # 22
Which NVIDIA software provides the capability to virtualize a GPU?

A. Horizon
B. virtGPU
C. vGPU

정답：C

설명：
NVIDIA vGPU (Virtual GPU) software enables GPU virtualization by partitioning a physical GPU into multiple virtual instances, assignable to virtual machines or containers for accelerated workloads. Horizon is a VMware product, and "virtGPU" isn't an NVIDIA offering, confirming vGPU as the correct solution.
(Reference: NVIDIA vGPU Documentation, Overview Section)
