質問 # 90
In an AI environment, the NVIDIA software stack plays a crucial role in ensuring seamless operations across different stages of the AI workflow. Which components of the NVIDIA software stack would you use to accelerate AI model training and deployment? (Select two)
正解：B、D
解説：
For AI model training and deployment:
* NVIDIA cuDNN(A) accelerates training by providing optimized GPU primitives (e.g., convolutions) for deep neural networks, used by frameworks like PyTorch and TensorFlow.
* NVIDIA TensorRT(B) optimizes models for deployment, enhancing inference speed and efficiency on GPUs.
* NVIDIA DGX-1(C) is hardware, not a software component.
* NVIDIA Nsight(D) is for profiling, not direct acceleration of training/deployment.
* NVIDIA DeepStream SDK(E) is for video analytics, not general AI workflows.
cuDNN and TensorRT are core to NVIDIA's AI software stack (A and B).
質問 # 91
How is out-of-band management utilized by network operators in an AI environment?
正解：A
解説：
Out-of-band management provides a dedicated channel, separate from the production network, for remotely managing and troubleshooting devices (e.g., switches, servers) in an AI environment. This ensures control and recovery even if the primary network fails, unlike options tied to model training, compute power, or traffic prioritization.
質問 # 92
A healthcare company is using NVIDIA AI infrastructure to develop a deep learning model that can analyze medical images and detect anomalies. The team has noticed that the model performs well during training but fails to generalize when tested on new, unseen data. Which of the following actions is most likely to improve the model's generalization?
正解：B
解説：
Applyingdata augmentation techniques(C) is the most likely action to improve the model's generalization on unseen medical imaging data. Let's dive into why:
* What is generalization?: Generalization is a model's ability to perform well on new, unseen data, avoiding overfitting to the training set. Overfitting occurs when a model memorizes training data (e.g., specific image patterns) rather than learning robust features (e.g., anomaly shapes).
* Role of data augmentation: Augmentation artificially expands the training dataset by applying transformations (e.g., rotations, flips, brightness changes) to medical images, simulating real-world variability (e.g., different lighting, angles in scans). This forces the model to learn invariant features, improving its performance on diverse test data. For example, rotating an X-ray image ensures the model recognizes anomalies regardless of orientation.
* Implementation: NVIDIA's DALI or cuAugment can GPU-accelerate augmentation,integrating seamlessly with training pipelines on NVIDIA infrastructure. Techniques like random crops or noise injection are particularly effective for medical imaging.
* Evidence: The symptom-high training accuracy, low test accuracy-indicates overfitting, a common issue in deep learning, especially with limited or uniform datasets like medical images. Augmentation is a standard remedy.
Why not the other options?
* A (Fewer epochs): Reduces training time, potentially underfitting, not addressing overfitting.
* B (Larger batch size): Improves training stability but doesn't inherently enhance generalization; it may even mask overfitting by smoothing gradients.
* D (More complex model): Increases capacity, worsening overfitting if data variety isn't addressed.
NVIDIA's healthcare AI resources endorse augmentation for robust models (C).
質問 # 93
As an IT Professional, you have been assigned to optimize the performance of a deep learning model. Which of the following is a benefit of NVIDIA TensorRT?
正解：C
解説：
NVIDIA TensorRT is a high-performance deep learning inference library that optimizes trained models, improving inference speed and reducing latency without retraining the model.
質問 # 94
Which type of GPU core was designed to offer multi-precision computing for deep learning training and inference?
正解：A
解説：
Tensor Cores are specialized GPU cores designed to accelerate multi-precision matrix operations, which are fundamental for deep learning training and inference, providing significant speed-ups over standard CUDA cores.
