CompTIA Data+ (DA0-001) — Question 157

A business analyst reviews the following text:

txt = “I have registered for a certification exam and will take it within a couple of months. I need to work hard to pass the exam with flying colors.”

The analyst then splits the string into two parts:

txt1 = “I have registered for a certification exam and will take it within a couple of months.”

txt2 = “I need to work hard to pass the exam with flying colors.”

Which of the following BEST describes the process the business analyst is following?

Answer options

• A. Data blending
• B. Data appending
• C. Imputation
• D. String manipulation

Correct answer: D

Explanation

The correct answer is D, String manipulation, because the analyst is dividing a single string into two distinct strings. The other options do not apply as data blending involves combining data from different sources, data appending refers to adding data to an existing dataset, and imputation is used for filling in missing values.
