Answer: D


NEW QUESTION # 176
A project manager requests an unscheduled report that provides a list of clients. Which of the following frequencies is best for this report?

Answer: C

Explanation:
An ad hoc report is created on demand to satisfy a specific, unscheduled request. Since the project manager requested a report outside the regular reporting schedule, an ad hoc report is the most appropriate choice.


NEW QUESTION # 177
A data analyst receives a request for the current employee head count and runs the following SQL statement:
SELECT COUNT(EMPLOYEE_ID) FROM JOBS
The returned head count is higher than expected because employees can have multiple jobs.
Which of the following should return an accurate employee head count?

Answer: C

Explanation:
Counting distinct employee IDs returns each employee only once, even if the employee appears in multiple job records, which produces an accurate head count.


NEW QUESTION # 178
A developer builds an online survey that requires all questions to have an answer. Which of the following inconsistencies does this setting prevent?

Answer: C

Explanation:
This question pertains to theData Governancedomain, focusing on data quality and consistency in survey design. Requiring all questions to have an answer ensures a specific type of data quality.
* Missing values (Option A): Requiring answers prevents missing values (NULLs or blanks) in the survey responses, which is the primary inconsistency this setting addresses.
* Duplication (Option B): Duplication refers to repeated records, not prevented by requiring answers.
* Data corruption (Option C): Data corruption involves damaged or altered data, not related to missing answers.
* Completeness (Option D): Completeness is the concept of having all necessary data, but "missing values" is the specific inconsistency prevented here.
The DA0-002 Data Governance domain includes "data quality control concepts," and preventing missing values ensures data integrity in survey responses.
