CompTIA DY0-001 시험요강:

주제소개
주제 1
  • Specialized Applications of Data Science: This section of the exam measures skills of a Senior Data Analyst and introduces advanced topics like constrained optimization, reinforcement learning, and edge computing. It covers natural language processing fundamentals such as text tokenization, embeddings, sentiment analysis, and LLMs. Candidates also explore computer vision tasks like object detection and segmentation, and are assessed on their understanding of graph theory, anomaly detection, heuristics, and multimodal machine learning, showing how data science extends across multiple domains and applications.
주제 2
  • Operations and Processes: This section of the exam measures skills of an AI
  • ML Operations Specialist and evaluates understanding of data ingestion methods, pipeline orchestration, data cleaning, and version control in the data science workflow. Candidates are expected to understand infrastructure needs for various data types and formats, manage clean code practices, and follow documentation standards. The section also explores DevOps and MLOps concepts, including continuous deployment, model performance monitoring, and deployment across environments like cloud, containers, and edge systems.
주제 3
  • Mathematics and Statistics: This section of the exam measures skills of a Data Scientist and covers the application of various statistical techniques used in data science, such as hypothesis testing, regression metrics, and probability functions. It also evaluates understanding of statistical distributions, types of data missingness, and probability models. Candidates are expected to understand essential linear algebra and calculus concepts relevant to data manipulation and analysis, as well as compare time-based models like ARIMA and longitudinal studies used for forecasting and causal inference.
주제 4
  • Modeling, Analysis, and Outcomes: This section of the exam measures skills of a Data Science Consultant and focuses on exploratory data analysis, feature identification, and visualization techniques to interpret object behavior and relationships. It explores data quality issues, data enrichment practices like feature engineering and transformation, and model design processes including iterations and performance assessments. Candidates are also evaluated on their ability to justify model selections through experiment outcomes and communicate insights effectively to diverse business audiences using appropriate visualization tools.
주제 5
  • Machine Learning: This section of the exam measures skills of a Machine Learning Engineer and covers foundational ML concepts such as overfitting, feature selection, and ensemble models. It includes supervised learning algorithms, tree-based methods, and regression techniques. The domain introduces deep learning frameworks and architectures like CNNs, RNNs, and transformers, along with optimization methods.

질문 # 42
Which of the following types of machine learning is a GPU most commonly used for?

정답：A

설명：
# GPUs (Graphics Processing Units) are optimized for parallel computations, which are essential for training deep neural networks. These models involve massive matrix operations across multiple layers, making GPUs significantly faster than CPUs in deep learning tasks.
Why the other options are incorrect:
* B: Clustering (e.g., k-means) can benefit from acceleration but doesn't usually require GPU-level computation.
* C: NLP tasks may use GPUs if they involve deep learning (e.g., transformers), but the correct choice is the model type.
* D: Tree-based models (e.g., decision trees, random forests) typically run efficiently on CPUs.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.3:"Deep learning models, such as neural networks, are computationally intensive and commonly require GPUs for efficient training."

질문 # 43
A data scientist wants to digitize historical hard copies of documents. Which of the following is the best method for this task?

정답：A

설명：
# Optical Character Recognition (OCR) is the process of converting scanned images or hard copy text into machine-encoded text. It is the standard technique for digitizing printed or handwritten content.
Why the other options are incorrect:
* A: Word2vec is for generating word embeddings from digital text.
* C: Latent Semantic Analysis analyzes semantic structure of existing digital documents.
* D: Semantic segmentation is used in image processing for pixel-wise classification - not text extraction.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 6.3:"OCR converts scanned physical documents into text files that can be searched, analyzed, or stored digitally."
* Practical NLP Applications, Chapter 2:"OCR is a prerequisite for turning printed or written material into structured data suitable for text analytics."

질문 # 44
A data scientist is presenting the recommendations from a monthslong modeling and experiment process to the company's Chief Executive Officer. Which of the following is the best set of artifacts to include in the presentation?

정답：C

설명：
Executive audiences need concise, high-level insights: what you found (results), what you suggest (recommendations), why it matters (justifications), and visual summaries (clear charts). Detailed methods, code, or raw data aren't appropriate at the C-suite level.


질문 # 45
In a modeling project, people evaluate phrases and provide reactions as the target variable for the model. Which of the following best describes what this model is doing?

정답：A

설명：
The model predicts people's reactions (e.g., positive, negative, neutral) to given phrases, which is the core of sentiment analysis.


질문 # 46
A data scientist is working with a data set that has ten predictors and wants to use only the predictors that most influence the results. Which of the following models would be the best for the data scientist to use?

정답：B

설명：
LASSO regression uses an L1 penalty that drives less‐important feature coefficients to exactly zero, effectively selecting only the predictors that most influence the outcome.
