CompTIA Data+ Exam (2025) Sample Questions (Q93-Q98):

NEW QUESTION # 93
A product goes viral on social media, creating high demand. Distribution channels are facing supply chain issues because the testing and training models that are used for sales forecasting have not encountered similar demand. Which of the following best describes this situation?

A. Incorrect sizing
B. Model bias
C. Data drift
D. Skewing

Answer: C

Explanation:
This question pertains to theData Analysisdomain, focusing on issues with forecasting models. The scenario describes a sudden change in demand (viral product) that the model couldn't predict because it hasn't seen similar patterns before.
* Model bias (Option A): Model bias occurs when a model systematically favors certain outcomes due to flawed training data, but this scenario is about a change in data patterns, not bias.
* Data drift (Option B): Data drift occurs when the statistical properties of the data change over time (e.
g., sudden high demand due to virality), causing the model to perform poorly because it was trained on different patterns, which fits the scenario.
* Incorrect sizing (Option C): This term is vague and not a standard concept in data analysis for this context.
* Skewing (Option D): Skewing refers to data distribution asymmetry, not a change in data patterns affecting model performance.
The DA0-002 Data Analysis domain includes understanding "applying the appropriate descriptive statistical methods," and data drift is a key concept in forecasting when data patterns change unexpectedly.

NEW QUESTION # 94
A database administrator needs to implement security triggers for an organization's user information database.
Which of the following data classifications is the administrator most likely using? (Select two).

A. Private
B. Sensitive
C. Public
D. Open
E. Encrypted
F. Non-Sensitive

Answer: A,B

Explanation:
This question pertains to theData Governancedomain, focusing on data classification for security purposes.
User information databases typically contain personal data, and security triggers (e.g., alerts for unauthorized access) require classifying data to determine protection levels.
* Public (Option A): Public data is openly accessible (e.g., company brochures), not suitable for user information requiring security triggers.
* Open (Option B): Open isn't a standard data classification; it's similar to public and not applicable here.
* Sensitive (Option C): Sensitive data includes information that, if exposed, could cause harm (e.g., user emails, roles), which fits user information and warrants security triggers.
* Non-Sensitive (Option D): Non-sensitive data doesn't require protection, so it wouldn't need security triggers.
* Private (Option E): Private data includes PII (e.g., names, addresses) in user information databases, requiring security measures like triggers to protect against breaches.
* Encrypted (Option F): Encrypted refers to a data state, not a classification; data can be classified as private or sensitive and then encrypted.
The DA0-002 Data Governance domain includes "data quality control concepts," such as classifying data to apply appropriate security measures. Sensitive and private classifications are most relevant for user information.
Reference: CompTIA Data+ DA0-002 Draft Exam Objectives, Domain 5.0 Data Governance.

NEW QUESTION # 95
A data analyst creates a report, and some of the fields are empty. Which of the following conditions should the analyst add to a query to provide a list of all the records with empty fields?

A. WHERE [ColumnName] IS NULL
B. WHERE [ColumnName] = NULL
C. WHERE [ColumnName] = 'NULL'
D. WHERE [ColumnName] IS NOT NULL

Answer: A

Explanation:
This question falls under theData Analysisdomain, focusing on SQL queries to identify data issues. The task is to find records with empty fields, which in SQL means NULL values.
* WHERE [ColumnName] = NULL (Option A): In SQL, NULL cannot be compared using "="; this syntax is incorrect.
* WHERE [ColumnName] IS NULL (Option B): This is the correct SQL syntax to identify NULL values, which represent empty fields.
* WHERE [ColumnName] IS NOT NULL (Option C): This finds non-empty fields, the opposite of the requirement.
* WHERE [ColumnName] = 'NULL' (Option D): This checks for the string "NULL," not a true NULL value, which is incorrect.
The DA0-002 Data Analysis domain includes "applying the appropriate descriptive statistical methods using SQL queries," such as identifying NULL values with IS NULL.
Reference: CompTIA Data+ DA0-002 Draft Exam Objectives, Domain 3.0 Data Analysis.

NEW QUESTION # 96
Which of the following best describes the function of a data type?

A. To identify the program needed to open a file
B. To make the addition of individual records simpler
C. To differentiate the real value of the field in its context
D. To provide a generic identifier for files used in analysis

Answer: C

Explanation:
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.

NEW QUESTION # 97
A data analyst is generating a custom report for a Chief Executive Officer's executive meeting. Later, the analyst learns that other custom reports will be required for future executive meetings. Which of the following delivery methods should the analyst use?

A. Ad hoc
B. Recurring
C. Real-time
D. Self-service

Answer: B

Explanation:
This question falls under theVisualization and Reportingdomain of DA0-002, which involves selecting appropriate delivery methods for reports. The scenario describes a need for custom reports for future executive meetings, implying a scheduled, repeated delivery.
* Ad hoc (Option A): Ad hoc reports are generated on-demand for one-time use, not suitable for ongoing needs.
* Real-time (Option B): Real-time delivery provides live data updates, which isn't necessary for scheduled executive meetings.
* Recurring (Option C): Recurring delivery involves scheduling reports to be generated and delivered at regular intervals (e.g., weekly or monthly), which fits the need for future executive meetings.
* Self-service (Option D): Self-service allows users to generate reports themselves, but the scenario implies the analyst will create the reports.
The DA0-002 Visualization and Reporting domain includes understanding "the appropriate visualization in the form of a report" with delivery methods , and recurring delivery aligns with scheduled reporting needs.
