CompTIA CASP+ (CAS-003) — Question 215

A medical device company is implementing a new COTS antivirus solution in its manufacturing plant. All validated machines and instruments must be retested for interoperability with the new software.
Which of the following would BEST ensure the software and instruments are working as designed?

Answer options

• A. System design documentation
• B. User acceptance testing
• C. Peer review
• D. Static code analysis testing
• E. Change control documentation

Correct answer: B

Explanation

User acceptance testing (UAT) is the most effective method for ensuring that the software and instruments work as intended since it involves end-users validating the functionality in real-world scenarios. The other options, while important for various stages of development, do not directly involve user validation and may not capture all interoperability issues.
