NVIDIA-Certified-Professional Accelerated Data Science 認定 NCP-ADS 試験問題 (Q53-Q58):

質問 # 53
A data scientist is working with large-scale datasets in a RAPIDS AI pipeline and needs to efficiently process and organize the data while leveraging GPU acceleration.
Which of the following approaches best ensures optimized processing and memory management when using NVIDIA technologies?

A. Process data using Apache Spark on CPU before transferring results to GPU for model training.
B. Write intermediate data to disk as CSV files before reading them back into RAPIDS AI to avoid memory overflow.
C. Use cuDF to store and process data in GPU memory, leveraging its vectorized operations for transformations and aggregations.
D. Store data in a pandas DataFrame first and then convert it to cuDF only when GPU operations are needed.

正解：C

質問 # 54
A data scientist is using NVIDIA RAPIDS to perform statistical analysis as part of exploratory data analysis (EDA) on a dataset containing millions of product reviews. They need to compute basic descriptive statistics such as mean, median, and variance efficiently.
Which of the following methods is the most appropriate for performing these calculations on GPUs?

A. Use cuDF's built-in statistical functions like .mean(), .median(), and .var()
B. Convert the dataset into a PyTorch tensor and use PyTorch's statistical methods
C. Use NumPy's statistical functions, such as numpy.mean() and numpy.var()
D. Use a traditional SQL database to compute statistics and then transfer results to the GPU

正解：A

質問 # 55
After profiling a deep learning model using NVIDIA DLProf, you notice that a specific GEMM (General Matrix Multiplication) operation takes significantly longer than expected. The profiler output reveals that tensor cores are underutilized despite having an Ampere-based GPU with Tensor Cores enabled.
Which of the following actions is the MOST appropriate to improve performance?

A. Disable CUDA graphs and enforce PyTorch's eager execution mode to improve kernel execution order.
B. Increase the batch size to maximize GPU memory usage and reduce kernel launch overhead.
C. Switch from stochastic gradient descent (SGD) to Adam optimizer, as Adam improves convergence and computational efficiency.
D. Convert the model's data type to float16 or bfloat16 and re-run the training with automatic mixed precision (AMP).

正解：D

質問 # 56
You are working with a large dataset in a cloud environment for a deep learning model. The dataset consists of several features including numerical values, categorical data, and timestamps.
Which of the following choices would result in the most efficient use of GPU and cloud resources when determining the optimal data type for each feature? (Select three)

A. Use datetime64[ns] for timestamp features to ensure high precision.
B. Use int8 for categorical features where there are fewer than 256 categories.
C. Use float64 for all numerical features to ensure maximum precision.
D. Use int32 for all numerical features to save memory.
E. Use object data types for categorical features to avoid type conversion overhead.

正解：A、B、D

質問 # 57
You are training a convolutional neural network (CNN) model with a large dataset on a single GPU.
The model is consuming too much GPU memory, and training is slow.
Which of the following techniques would help you reduce GPU memory consumption while maintaining or improving the efficiency of training? (Select two)

A. Use a smaller batch size to reduce the memory requirements per training iteration, allowing for faster training.
B. Implement mixed precision training to lower memory usage and speed up computation without losing accuracy.
C. Use automatic differentiation for every operation to save memory during the backpropagation phase.
D. Decrease the size of the model by reducing the number of layers or the number of filters per layer.
E. Use batch normalization to reduce memory usage by skipping some of the computations during training.

正解：A、B
