Your question is Testing Resource Load and Metrics. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you approach testing resource load for a React application, including what metrics you would use, what data you would base it on, and where you would obtain that data?
Explain how you would plan the test, establish realistic workload assumptions, instrument the application, and interpret results. Cover both browser-side resources and relevant backend or network dependencies.
