CompTIA DataAI Certification Exam Sample Questions (Q21-Q26):

NEW QUESTION # 21
An analyst wants to show how the component pieces of a company's business units contribute to the company's overall revenue. Which of the following should the analyst use to best demonstrate this breakdown?

Answer: A

Explanation:
# A Sankey diagram is ideal for illustrating flow-based relationships, such as how different units or sources contribute to a total. It's especially effective for showing proportions, hierarchy, and decomposition - such as revenue contribution by business units.
Why the other options are incorrect:
* A: Box plots show distributions and spread - not contributions or breakdowns.
* C: Scatter plot matrix explores relationships between numeric variables, not part-to-whole relationships.
* D: Residual charts are diagnostic tools for regression - not for revenue visualization.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 5.5:"Sankey diagrams are useful for visualizing contributions, flows, and proportional allocations across categories."
* Data Visualization Best Practices, Chapter 7:"Sankey charts are preferred when tracking contributions from multiple inputs to a unified output."


NEW QUESTION # 22
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?

Answer: B

Explanation:
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.


NEW QUESTION # 23
A data scientist is building a proof of concept for a commercialized machine-learning model. Which of the following is the best starting point?

Answer: C

Explanation:
# In the proof-of-concept phase, the first practical step is model selection - identifying which modeling technique is most appropriate based on the nature of the problem, data, and business goal. Literature reviews are helpful but usually precede model experimentation.
Why the other options are incorrect:
* A: Literature review informs planning but isn't the first hands-on step.
* B: Performance evaluation comes after models are built.
* C: Hyperparameter tuning applies after a model is chosen.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.1:"Model selection is a critical step during early prototyping when evaluating different algorithms for feasibility."
* CRISP-DM Framework - Modeling Phase:"Selecting candidate models is the first step in model development after understanding the data."


NEW QUESTION # 24
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?

Answer: A

Explanation:
# For executive-level presentations, the focus should be on strategic outcomes. Therefore, concise results, clear actionable recommendations, visual summaries (charts), and minimal justifications are best. Technical details such as p-values, code, or full methods are too granular.
Why the other options are incorrect:
* A: Too method-heavy for executive audiences.
* C: Includes code reviews - not suitable for a CEO.
* D: Overly technical for high-level stakeholders.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 5.5:"Executive communication should focus on outcome-driven recommendations, high-level insights, and actionable visuals."
* Harvard Business Review - Communicating Data to Executives:"Avoid technical detail. Use visuals and clearly stated recommendations supported by business-focused justifications."


NEW QUESTION # 25
Given the equation:

Xt = # + #1Xt#1 + #t, where #t # N(0, ##²)
Which of the following time series models best represents this process?

Answer: B

Explanation:
# The provided equation represents an autoregressive model of order 1 (AR(1)). It describes Xt as a function of its immediately prior value (Xt#1) plus white noise.
Key identifiers:
* No differencing (so not ARIMA).
* No moving average term (so not ARMA).
* No seasonal component (so not SARIMA).
Why the other options are incorrect:
* A: ARIMA(1,1,1) includes integration and MA terms, which are absent here.
* B: ARMA(1,1) includes both AR and MA terms, but only AR is present.
* C: SARIMA involves seasonal and differencing components - not applicable here.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 3.5:"AR(p) models describe a variable as dependent on its previous values with no differencing or moving average."
* Time Series Analysis Textbook, Chapter 4:"Xt = #Xt-1 + #t describes an AR(1) process when #t is white noise."
