QUESTION: 9

Which architecture is the core concept behind large language models?

BERT Large model
State space model
Transformer model
Attention model

Answer(s): C

Explanation:

The Transformer model is the foundational architecture for modern large language models (LLMs). Introduced in the paper "Attention is All You Need," it uses stacked layers of self-attention mechanisms and feed-forward networks, often in encoder-decoder or decoder-only configurations, to efficiently capture long-range dependencies in text.
While BERT (a specific Transformer-based model) and attention mechanisms (a component of Transformers) are related, the Transformer itself is the core concept. State space models are an alternative approach, not the primary basis for LLMs.

QUESTION: 10

What is a key value of using NVIDIA NIMs?

They provide fast and simple deployment of AI models.
They have community support.
They allow the deployment of NVIDIA SDKs.

Answer(s): A

Explanation:

NVIDIA NIMs (NVIDIA Inference Microservices) are pre-built, GPU-accelerated microservices with standardized APIs, designed to simplify and accelerate AI model deployment across diverse environments--clouds, data centers, and edge devices. Their key value lies in enabling fast, turnkey inference without requiring custom deployment pipelines, reducing setup time and complexity.
While community support and SDK deployment may be tangential benefits, they are not the primary focus of NIMs.

QUESTION: 11

The foundation of the NVIDIA software stack is the DGX OS.
Which of the following Linux distributions is DGX OS built upon?

Ubuntu
Red Hat
CentOS

Answer(s): A

Explanation:

DGX OS, the operating system powering NVIDIA DGX systems, is built on Ubuntu Linux, specifically the Long-Term Support (LTS) version. It integrates Ubuntu's robust base with NVIDIA-specific enhancements, including GPU drivers, tools, and optimizations tailored for AI and high-performance computing workloads. Neither Red Hat nor CentOS serves as the foundation for DGX OS, making Ubuntu the correct choice.

QUESTION: 12

What is the name of NVIDIA's SDK that accelerates machine learning?

Clara
RAPIDS
cuDNN

Answer(s): C

Explanation:

The CUDA Deep Neural Network library (cuDNN) is NVIDIA's SDK specifically designed to accelerate machine learning, particularly deep learning tasks. It provides highly optimized implementations of neural network primitives--such as convolutions, pooling, normalization, and activation functions--leveraging GPU parallelism. Clara focuses on healthcare applications, and RAPIDS accelerates data science workflows, but cuDNN is the core SDK for machine learning acceleration.

QUESTION: 13

Which aspect of computing uses large amounts of data to train complex neural networks?

Machine learning
Deep learning
Inferencing

Answer(s): B

Explanation:

Deep learning, a subset of machine learning, relies on large datasets to train multi-layered neural networks, enabling them to learn hierarchical feature representations and complex patterns autonomously.
While machine learning encompasses broader techniques (some requiring less data), deep learning's dependence on vast data volumes distinguishes it. Inferencing, the application of trained models, typically uses smaller, real-time inputs rather than extensive training data.

QUESTION: 14

Which of the following statements correctly differentiates between AI, Machine Learning, and Deep Learning?

Machine Learning is a subset of AI, and AI is a subset of Deep Learning.
AI and Deep Learning are the same, while Machine Learning is a separate concept.
AI is a subset of Machine Learning, and Machine Learning is a subset of Deep Learning.
Deep Learning is a subset of Machine Learning, and Machine Learning is a subset of AI.

Answer(s): D

Explanation:

Artificial Intelligence (AI) is the overarching field encompassing techniques to mimic human intelligence. Machine Learning (ML), a subset of AI, involves algorithms that learn from data. Deep Learning (DL), a specialized subset of ML, uses neural networks with many layers to tackle complex tasks. This hierarchical relationship--DL within ML, ML within AI--is the correct differentiation, unlike the reversed or conflated options.

QUESTION: 15

How is the architecture different in a GPU versus a CPU?

A GPU acts as a PCIe controller to maximize bandwidth.
A GPU is architected to support massively parallel execution of simple instructions.
A GPU is a single large and complex core to support massive compute operations.

Answer(s): B

Explanation:

A GPU's architecture is designed for massive parallelism, featuring thousands of lightweight cores that execute simple instructions across vast data elements simultaneously--ideal for tasks like AI training. In contrast, a CPU has fewer, complex cores optimized for sequential execution and branching logic. GPUs don't function as PCIe controllers (a hardware role), nor are they single-core designs, making the parallel execution focus the key differentiator.

QUESTION: 16

What factors have led to significant breakthroughs in Deep Learning?

Advances in hardware, availability of fast internet connections, and improvements in training algorithms.
Advances in sensors, availability of large datasets, and improvements to the "Bag of Words" algorithm.
Advances in hardware, availability of large datasets, and improvements in training algorithms.
Advances in smartphones, social media sites, and improvements in statistical techniques.

Answer(s): C

Explanation:

Deep learning breakthroughs stem from three pillars: advances in hardware (e.g., GPUs and TPUs) providing the compute power for large-scale neural networks; the availability of large datasets offering the data volume needed for training; and improvements in training algorithms (e.g., optimizers like Adam, novel architectures like Transformers) enhancing model efficiency and accuracy.
While internet speed, sensors, or smartphones play roles in broader tech, they're less directly tied to deep learning's core advancements.
