Certified Information Systems Auditor (CISA) — Question 1190

Which of the following is the BEST approach to validate whether a streaming site can continue to provide service during a period of live streaming with an anticipated high volume of viewers?

Answer options

• A. Fuzzing
• B. Usability test
• C. Fault grading
• D. Load test

Correct answer: D

Explanation

The correct answer is D, Load test, as it specifically measures how the system performs under high traffic conditions, which is critical for live streaming events. Options A, B, and C do not focus on assessing performance under load; fuzzing tests for security vulnerabilities, usability tests evaluate user experience, and fault grading examines error handling rather than service capacity.
