CompTIA Data+ Exam Sample Questions (Q203-Q208):

NEW QUESTION # 203
A data analyst worked on a project that contained medical content and a list of requirements.
Which of the following are most likely the reasons the privacy team flagged the analyst's report?
(Choose two.)

A. The exclusion of data occurred only after a participant invoked a right to withdraw.
B. The directive did not mention that it was vital for PHI to be encrypted in the data set.
C. The collection of data was stored according to protocols that are too strict.
D. The practice of data masking was irreversible and all PII was lost.
E. The retention policy did not allow data to be used beyond one year after the project.
F. The method used to anonymize identifying values in the data was insufficient.

Answer: B,F

Explanation:
Medical data contains highly sensitive information, so insufficient anonymization of identifying values can leave individuals vulnerable to re-identification and violate privacy requirements.
Additionally, PHI (Protected Health Information) should be encrypted to protect confidentiality and meet regulatory and security expectations. These issues would be likely reasons for a privacy team to flag the report.

NEW QUESTION # 204
A developer builds an online survey that requires all questions to have an answer. Which of the following inconsistencies does this setting prevent?

A. Duplication
B. Data corruption
C. Missing values
D. Completeness

Answer: C

Explanation:
Requiring every survey question to be answered prevents missing values by ensuring that no response fields are left blank. This helps maintain complete data collection and reduces gaps in the dataset.

NEW QUESTION # 205
A data analyst creates a report that identifies the middle 50% of the collected data. Which of the following best describes the analyst's findings?

A. Skewness from the slope
B. Mean variance
C. The difference between mode and median
D. Interquartile range

Answer: D

Explanation:
This question pertains to theData Analysisdomain, focusing on statistical measures. The middle 50% of a dataset refers to a specific statistical concept related to data distribution.
* Interquartile range (Option A): The interquartile range (IQR) is the range between the first quartile (Q1, 25th percentile) and the third quartile (Q3, 75th percentile), representing the middle 50% of the data, which matches the description.
* The difference between mode and median (Option B): This measures the spread between two central tendency metrics but doesn't represent the middle 50% of the data.
* Mean variance (Option C): Variance measures data dispersion around the mean, not the middle 50%.
* Skewness from the slope (Option D): Skewness measures data asymmetry, and "slope" is irrelevant here.
The DA0-002 Data Analysis domain includes "applying the appropriate descriptive statistical methods," and the IQR is the standard measure for the middle 50% of a dataset.

NEW QUESTION # 206
A data analyst is gathering data from multiple tables in a database. The analyst needs certain columns from each table. Which of the following is the best method to accomplish this task?

A. Join
B. Union
C. Aggregate
D. Nest

Answer: A

Explanation:
This question falls under theData Acquisition and Preparationdomain, focusing on combining data from multiple tables. The analyst needs specific columns from each table, suggesting a method to combine data horizontally based on relationships.
* Aggregate (Option A): Aggregation (e.g., SUM, COUNT) summarizes data, not suitable for combining columns from tables.
* Union (Option B): Union stacks tables vertically, requiring identical structures, but the analyst needs specific columns, likely based on relationships, not a vertical stack.
* Nest (Option C): Nesting is used for hierarchical data (e.g., JSON), not for combining relational tables.
* Join (Option D): A join (e.g., INNER JOIN) combines tables horizontally based on a common key, allowing the analyst to select specific columns from each table, which fits the task.
The DA0-002 Data Acquisition and Preparation domain includes "executing data manipulation," and joining tables is the best method for combining specific columns from multiple tables.

NEW QUESTION # 207
An analyst must use the same data to create reports for police patrol supervisors, the city council, and a public website. Which of the following is the best way to differentiate the reports?

A. Accessibility
B. Detail levels
C. Sensitivity
D. Persona type

Answer: D

Explanation:
This question falls under theVisualization and Reportingdomain, focusing on tailoring reports for different audiences. The same data is used for three distinct groups (supervisors, city council, public), requiring differentiation.
* Persona type (Option A): Persona types define the audience's needs and preferences (e.g., supervisors need operational details, the city council needs summaries, the public needs simplified data), making this the best way to differentiate the reports.
* Detail levels (Option B): Detail levels are a result of persona types, not the method of differentiation.
* Accessibility (Option C): Accessibility ensures access for all users (e.g., screen readers), but it's not the primary way to differentiate content.
* Sensitivity (Option D): Sensitivity determines data access (e.g., confidential vs. public), but the scenario implies all reports use the same data, just presented differently.
The DA0-002 Visualization and Reporting domain emphasizes "translating business requirements to form the appropriate visualization," and persona types guide report differentiation for diverse audiences.
