Certified Internal Auditor (CIA) Part 2: Practice of Internal Auditing — Question 215

An internal auditor was assigned to assess the risks related to the oil dispatch process. The auditor visited the oil dispatch facilities, met the manager responsible for oil sales, saw oil being loaded onto railway carriers, and talked to employees involved in the process. Which of the following best describes these audit testing methods?

Answer options

Correct answer: D

Explanation

The correct answer is D because the auditor conducted physical observation of the oil loading process and obtained testimonial evidence through discussions with employees. The other options do not fully capture the combination of methods that involve direct observation and employee interactions as effectively as option D does.
