CompTIA DY0-001 認定試験の出題範囲：

トピック 出題範囲
トピック 1
  • 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.
トピック 2
  • 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. It also addresses unsupervised learning, dimensionality reduction, and clustering models, helping candidates understand the wide range of ML applications and techniques used in modern analytics.
トピック 3
  • 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.
トピック 4
  • 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.
トピック 5
  • 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.

CompTIA DataAI Certification Exam 認定 DY0-001 試験問題 (Q40-Q45):

質問 # 40
Which of the following distributions would be best to use for hypothesis testing on a data set with 20 observations?

  • A. Normal
  • B. Student's t-
  • C. Power law
  • D. Uniform

正解：B

解説：
With only 20 observations and an unknown population variance, the t-distribution (with 𝑛 - 1 degrees of freedom) properly accounts for the extra uncertainty in the standard error when performing hypothesis tests.


質問 # 41
Which of the following belong in a presentation to the senior management team and/or C-suite executives?
(Choose two.)

  • A. High-level results
  • B. Full literature reviews
  • C. Security keys and login information
  • D. Code snippets
  • E. Detailed explanations of statistical tests
  • F. Final recommendations

正解：A、F

解説：
# Senior executives and the C-suite are primarily interested in decision-support insights rather than technical or academic depth. Thus, appropriate content includes:
* C. Final recommendations: Executives need clear actions or decisions.
* D. High-level results: Summarized performance, trends, or KPIs without technical jargon.
Why the other options are incorrect:
* A: Literature reviews are too detailed and academic.
* B: Code is technical and not relevant to business strategy.
* E: Statistical tests may overwhelm a non-technical audience.
* F: Sharing security keys violates cybersecurity protocols.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 5.5 (Communication & Visualization):
"Executive presentations should include concise, actionable insights and high-level summaries to support strategic decision-making."
* Harvard Business Review - Data Storytelling:"Executives value clear insights, visual summaries, and recommendations. Avoid technical deep dives unless specifically requested."

質問 # 42
Which of the following best describes the minimization of the residual term in a ridge linear regression?

  • A. e
  • B. e2
  • C. 0
  • D. |e|

正解：B

解説：
Ridge regression extends ordinary least squares by adding an L2 penalty on the coefficients, but it still minimizes the sum of squared residuals (e²) as its loss term.


質問 # 43
Which of the following image data augmentation techniques allows a data scientist to increase the size of a data set?

  • A. Clipping
  • B. Masking
  • C. Scaling
  • D. Cropping

正解：D

解説：
# Cropping involves selecting portions of an image to create multiple training samples from one image. This technique helps increase dataset size and variability, which improves model generalization.
Why the other options are incorrect:
* A: Clipping typically refers to limiting pixel values, not augmentation.
* C: Masking hides or removes parts of an image - used more in object detection or inpainting, not to expand the dataset.
* D: Scaling changes the image size but doesn't create new samples.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 6.3:"Cropping is a data augmentation strategy that allows for synthetic expansion of the dataset by generating multiple views."

質問 # 44
Which of the following measures would a data scientist most likely use to calculate the similarity of two text strings?

  • A. String indexing
  • B. k-nearest neighbors
  • C. Word cloud
  • D. Edit distance

正解：D

解説：
Edit distance quantifies how many single-character insertions, deletions, or substitutions are needed to transform one string into another, making it a direct measure of their similarity.
