CompTIA Data+ Exam (2025) 認定 DA0-002 試験問題 (Q37-Q42):
質問 # 37
A sales manager wants to understand how sales are trending year over year. Which of the following chart types is the most appropriate to display the information?
正解：B
解説：
This question falls under theVisualization and Reportingdomain, focusing on selecting the appropriate visualization for a specific data trend. The task is to show sales trends over time (year over year).
* Line (Option A): Line charts are ideal for displaying trends over time, such as year-over-year sales, as they clearly show changes and patterns across a continuous time axis.
* Donut (Option B): Donut charts show proportions or percentages of a whole, not suitable for time- based trends.
* Bubble (Option C): Bubble charts display three dimensions of data (e.g., size, x-axis, y-axis), not ideal for simple time trends.
* Hierarchy (Option D): Hierarchy charts (e.g., treemaps) show nested relationships, not time-based trends.
The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and a line chart is best for time-series trends.

質問 # 38
Which of the following is the best reason for a company to use a CSV file to share data instead of an Excel file?
正解：A
解説：
This question pertains to theData Concepts and Environmentsdomain, focusing on file formats for data sharing. The task is to identify the best reason to choose CSV over Excel for sharing data.
* CSV files can store different types of encoding (Option A): While CSV files can use different encodings, this isn't the primary reason to choose them over Excel.
* CSV files are not vendor-specific (Option B): CSV is a plain-text format that can be opened by any software, unlike Excel files, which are tied to Microsoft Excel, making CSV more interoperable and the best reason for sharing.
* CSV files are smaller in size (Option C): CSV files are often smaller due to their simplicity, but this isn't always the primary reason for sharing.
* CSV files are easier to change in text editors (Option D): While true, this isn't the most compelling reason for sharing data across systems.
The DA0-002 Data Concepts and Environments domain includes understanding "data schemas and dimensions," and CSV's vendor-neutral nature makes it ideal for sharing data.

質問 # 39
Which of the following best describes the function of a data type?
正解：A
解説：
This question falls under theData Concepts and Environmentsdomain, focusing on the purpose of data types in data management. Data types define how data is stored and interpreted.
* To provide a generic identifier for files used in analysis (Option A): Data types apply to fields within datasets, not files.
* To identify the program needed to open a file (Option B): File extensions (e.g., .csv) identify programs, not data types.
* To differentiate the real value of the field in its context (Option C): Data types (e.g., integer, string, date) define how a field's value is interpreted (e.g., "123" as a number vs. text), ensuring its real meaning in context, making this the correct answer.
* To make the addition of individual records simpler (Option D): Data types don't directly simplify record addition; they ensure proper data handling.
The DA0-002 Data Concepts and Environments domain includes understanding "data schemas and dimensions," and data types ensure fields are interpreted correctly in their context.

質問 # 40
Which of the following AI types is the best option for time-series forecasting?
正解：B
解説：
Foundational models are large AI models trained on vast amounts of data, often exhibiting strong generalization capabilities. While not specifically architected for time-series, their ability to learn complex patterns could potentially be leveraged for forecasting tasks through fine-tuning or specialized architectures built upon them.
In reality, the best AI types specifically designed for time-series forecasting include:
* Recurrent Neural Networks (RNNs), especially LSTMs and GRUs:These architectures are designed to handle sequential data and capture temporal dependencies.
* Transformer Networks:Originally developed for NLP, Transformers have shown remarkable success in time-series forecasting due to their ability to capture long-range dependencies.
* Traditional statistical models:ARIMA, Exponential Smoothing, and other statistical methods remain powerful and interpretable options for time-series analysis.
Therefore, while "foundational models" have some potential, it's important to understand that they aren't the primary or specifically designed AI type for time-series forecasting.
質問 # 41
A data analyst is creating a forecast for a product line introduced early last year. Which of the following should the analyst use to create projected sales and customer satisfaction for next year?
正解：B
解説：
This question pertains to theData Analysisdomain, focusing on data types and methods for forecasting. The task involves projecting sales (numerical) and customer satisfaction (likely ordinal,e.g., ratings), requiring appropriate data attributes.
* Standard deviation and constraints (Option A): Standard deviation measures data spread, and constraints are conditions, neither of which directly supports forecasting.
* Mean and median (Option B): Mean and median are descriptive statistics, not sufficient for forecasting future values.
* Boolean data and an array (Option C): Boolean data (true/false) and arrays (data structures) are not relevant for forecasting sales and satisfaction.
* Numerical and ordinal attributes (Option D): Sales are numerical (e.g., units sold), and customer satisfaction is often ordinal (e.g., 1-5 ratings). These attributes are suitable for forecasting models (e.g., time-series analysis for sales, regression for satisfaction).
The DA0-002 Data Analysis domain includes "applying the appropriate descriptive statistical methods," and numerical and ordinal attributes are key for forecasting sales and satisfaction.
