CompTIA Data+ Exam 認定 DA0-002 試験問題 (Q11-Q16):

質問 # 11
Given the following tables:

Which of the following data privacy practices is being used to protect employees' email addresses when creating a report?

正解：D

解説：
Masking hides sensitive data by replacing portions of the original value with obscured characters, such as replacing email addresses with "xxxxx@company.com" while preserving the format.


質問 # 12
A data analyst is building a new report using data from a sales column. Upon review, the analyst finds that the sales date is stored as a character type. Which of the following function types should the analyst use to filter by a specific month?

正解：B

解説：
Since the sales date is stored as a character (text) data type, the analyst must use string functions to extract or identify the month portion of the date value before filtering. String functions are designed to manipulate and analyze text data stored in character fields.


質問 # 13
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?

正解：A

解説：
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.

質問 # 14
An organization sees an increase in requests to view its online dashboard. Providing access is time-consuming. Which of the following actions should the data team take to provide access and ensure the security of the online portal?

正解：D

解説：
A self-service portal with user credentials allows users to request and access the dashboard independently while maintaining security through authentication and access controls. This approach reduces administrative effort, scales efficiently as requests increase, and ensures that only authorized users can access the online portal.


質問 # 15
A data analyst is working on a three-year project to deliver sales reports on a monthly basis. The client wants a thorough analysis into customer profiles for a specific region and month. Which of the following delivery methods best fulfills this request?

正解：B

解説：
An ad hoc delivery method is used when a stakeholder requests a detailed, specific analysis that is not part of the standard recurring reports. The request for a thorough analysis of customer profiles for a particular region and month is a targeted, one-time inquiry that is best fulfilled through an ad hoc report.
