질문 # 77
A data scientist wants to predict a person's travel destination. The options are:
* Branson, Missouri, United States
* Mount Kilimanjaro, Tanzania
* Disneyland Paris, Paris, France
* Sydney Opera House, Sydney, Australia
Which of the following models would best fit this use case?

정답：C

설명：
# Linear Discriminant Analysis (LDA) is a supervised classification method used to predict a categorical target (such as travel destination) based on multiple input features. It models decision boundaries between classes - which is appropriate when predicting a fixed set of destinations.
Why the other options are incorrect:
* B: k-means is unsupervised and doesn't use labeled output like travel destination.
* C: Latent Semantic Analysis is used for extracting relationships from textual data - not categorical prediction.
* D: PCA reduces dimensionality but doesn't classify.
Official References:
* CompTIA DataX (DY0-001) Official Study Guide - Section 4.1:"Linear Discriminant Analysis is used when the response variable is categorical and the objective is classification."
* Classification Techniques Guide, Chapter 7:"LDA excels in multi-class prediction when the input data is continuous and the output is a known category."

질문 # 78
Which of the following layer sets includes the minimum three layers required to constitute an artificial neural network?

정답：D

설명：
# A basic artificial neural network (ANN) consists of:
* An input layer to receive data
* At least one hidden layer to process the data
* An output layer to produce predictions
These three layers form the minimal architecture required for learning and transformation.
Why the other options are incorrect:
* A: Pooling layers are used in CNNs, not core ANN structure.
* B: Convolutional layers are specific to CNNs.
* D: Dropout is a regularization technique, not a required component.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.3:"ANNs must include an input layer, hidden layer(s), and an output layer to form a complete learning structure."
* Deep Learning Fundamentals, Chapter 3:"At a minimum, a neural network includes input, hidden, and output layers to process and propagate data."

질문 # 79
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?

정답：C

설명：
# 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."


질문 # 80
A data scientist would like to model a complex phenomenon using a large data set composed of categorical, discrete, and continuous variables. After completing exploratory data analysis, the data scientist is reasonably certain that no linear relationship exists between the predictors and the target. Although the phenomenon is complex, the data scientist still wants to maintain the highest possible degree of interpretability in the final model. Which of the following algorithms best meets this objective?

정답：C

설명：
# Decision trees offer excellent interpretability while handling complex, non-linear relationships and multiple variable types (categorical, discrete, continuous). They provide easy-to-understand visualizations and logic- based rules, making them ideal when transparency and insight are priorities.
Why other options are incorrect:
* A: Neural networks are powerful but are considered "black box" models, with low interpretability.
* C: Linear regression assumes a linear relationship, which contradicts the scenario.
* D: Random forests are ensembles of trees - more accurate, but less interpretable.
Official References:
* CompTIA DataX (DY0-001) Study Guide - Section 4.2:"Decision trees are interpretable models that support non-linear, multi-type data with logical branching."

질문 # 81
A data scientist is performing a linear regression and wants to construct a model that explains the most variation in the dat a. Which of the following should the data scientist maximize when evaluating the regression performance metrics?

정답：C
