CompTIA Cloud+ (CV0-003) — Question 68

A system administrator supports an application in the cloud, which includes a restful API that receives an encrypted message that is passed to a calculator system. The administrator needs to ensure the proper function of the API using a new automation tool. Which of the following techniques would be BEST for the administrator to use to accomplish this requirement?

Answer options

• A. Functional testing
• B. Performance testing
• C. Integration testing
• D. Unit testing

Correct answer: A

Explanation

Functional testing is the most suitable approach as it verifies that the API behaves as expected and meets the specified requirements. Performance testing focuses on the speed and responsiveness of the API, while integration testing examines how different components work together, and unit testing checks individual parts of the code, none of which directly ensure the API's proper functionality.
