CompTIA Data+ (DA0-001) — Question 225

An analyst is developing a form to collect data from clients. Which of the following techniques should the analyst use to best ensure data integrity?

Answer options

• A. Adding rules for data validation
• B. Making all fields required
• C. Enabling an ‘other’ option for each question
• D. Enabling text fields throughout the entire form

Correct answer: A

Explanation

The correct answer is A, as adding rules for data validation helps ensure that the data entered meets specific criteria, thus maintaining its integrity. While making all fields required (B) can increase the amount of data collected, it does not guarantee accuracy. The 'other' option (C) can lead to ambiguous responses, and enabling text fields (D) may allow for inconsistent or irrelevant data to be submitted.
