Pass the CompTIA CompTIA Data+ DA0-002 Questions and answers with CertsForce

This question pertains to theVisualization and Reportingdomain, focusing on selecting the appropriate communication method for a report. The requirements emphasize simplicity, clarity, accessibility, and automatic updates, which point to a specific approach.

Executive summary (Option A): An executive summary is a written document that summarizes metrics but isn’t typically updated automatically and may not be accessible toall levels without distribution.

Slide presentation (Option B): A slide presentation can be clear but requires manual updates and isn’t inherently accessible to all company levels.

Key performance indicator dashboard (Option C): A KPI dashboard provides a simple, visual summary of metrics, is clear and concise, can be understood by all levels, and can be set up to update automatically, meeting all requirements.

Open data portal (Option D): An open data portal provides raw data access, which may not be simple or easily understood by all levels.

The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and a KPI dashboard is the best approach for meeting these requirements.

This question pertains to theData Acquisition and Preparationdomain, focusing on tools for automating repeatable tasks in data processes. The task is to identify the most efficient programming method.

LLM (Option A): Large Language Models (e.g., GPT) are for text generation, not efficient for repeatable data tasks.

Deep learning (Option B): Deep learning is for complex pattern recognition (e.g., image classification), not efficient for simple repeatable tasks.

NLP (Option C): Natural Language Processing is for text analysis, not general repeatable tasks.

RPA (Option D): Robotic Process Automation (RPA) automates repetitive, rule-based tasks (e.g., data entry, file processing), making it the most efficient for programming repeatable tasks.

The DA0-002 Data Acquisition and Preparation domain includes "executing data manipulation," and RPA is a widely used method for automating repeatable data tasks.

This question falls under theVisualization and Reportingdomain, focusing on identifying tools used for business intelligence (BI), which typically involves data visualization and reporting.

SAS (Option A): SAS is a statistical analysis software, not primarily a BI tool focused on visualization.

Python (Option B): Python is a programming language, not a BI software, though it can be used for data analysis with libraries.

Notepad++ (Option C): Notepad++ is a text editor, not a BI tool.

Tableau (Option D): Tableau is a leading BI software designed for data visualization, dashboards, and reporting, making it the correct choice.

The DA0-002 Visualization and Reporting domain includes understanding "the appropriate visualization in the form of a report or dashboard," and Tableau is a recognized BI tool for this purpose.
