NEW QUESTION # 113
Which architecture is the core concept behind large language models?
Answer: D
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.
(Reference: NVIDIA AI Infrastructure and Operations Study Guide, Section on Large Language Models)
NEW QUESTION # 114
In a large enterprise cluster, frequent out-of-memory errors occur mid-experiment. What operational feature resolves this?
Answer: B
Explanation:
Reserving GPU memory and monitoring usage through the workload manager ensures that jobs are allocated sufficient resources and prevents multiple jobs from oversubscribing memory, avoiding out-of-memory errors during execution.
NEW QUESTION # 115
You are managing an AI data center where multiple GPUs are orchestrated across a large cluster to run various deep learning tasks. Which of the following actions best describes an efficient approach to cluster orchestration in this environment?
Answer: A
Explanation:
Implementing a Kubernetes-based orchestration system to dynamically allocate GPU resources based on workload demands is the most efficient approach for managing a multi-GPU AI cluster. Kubernetes, enhanced by NVIDIA's GPU Operator, supports dynamic scheduling, resource allocation, and scaling for deep learning tasks, ensuring optimal GPU utilization and adaptability.Option A (round-robin) ignores workload specifics, leading to inefficiency. Option B (least power) sacrifices performance for minor cost savings. Option D (most powerful GPU) creates bottlenecks and underutilizes other GPUs. NVIDIA's documentation on Kubernetes integration highlights its effectiveness for AI cluster orchestration.
NEW QUESTION # 116
How many 1 Gb Ethernet in-band network connections are in a DGX H100 system?
Answer: A
Explanation:
The DGX H100 system uses high-speed NVIDIA ConnectX-7 QSFP56 ports (supporting 10 GbE and above) for in-band management and storage traffic, with no 1 Gb Ethernet interfaces allocated to in- band networks. A single 1 GbE RJ45 port exists, but it's reserved for out-of-band Baseboard Management Controller (BMC) tasks, not in-band connectivity.
NEW QUESTION # 117
A customer is evaluating an AI cluster for training and is questioning why they should use a large number of nodes. Why would multi-node training be advantageous?
Answer: C
Explanation:
Multi-node training is advantageous when a model's size--its parameters, activations, and gradients-exceeds the memory capacity of a single GPU. By sharding the model across multiple nodes (using techniques like data parallelism or model parallelism), training becomes feasible and efficient. User count and inference scale are unrelated to training architecture needs, which focus on compute and memory distribution.
