Certified Information Systems Auditor (CISA) — Question 190

Which of the following types of testing would BEST mitigate the risk of a newly implemented system adversely impacting existing systems?

Answer options

• A. User acceptance testing (UAT)
• B. Functionality testing
• C. Sociability testing
• D. Unit testing

Correct answer: C

Explanation

Sociability testing focuses on how well the new system interacts with existing systems, which is crucial for identifying potential adverse impacts. User acceptance testing (UAT) is more about user satisfaction, functionality testing evaluates specific features, and unit testing checks individual components, none of which directly address the integration risks.
